A bright future

Permanent allurement motors are currently entering a new age of acceptance and will become added boundless in the next few years. New analysis conducted by Allied Bazaar Analysis apparent several factors that will accord to the added use.

According to AMR's research, the bazaar for abiding allurement motors will abound 11.7 percent by 2020 and be account $43.5 billion. Neodymium magnets are a key disciplinarian of advance in the sector, as they action able-bodied at top calefaction and are added accessible than before.

While attenuate apple magnets were ahead difficult to obtain, their accumulation became added consistent, which allows manufacturers to actualize abiding allurement motors. This access in accumulation has coincided with newfound appeal as electric motors are now acclimated in a array of industries alfresco manufacturing. New electric automobiles will accomplish all-encompassing use of the motors in their drive trains, for instance.

While new uses present agitative affairs for advance the majority of the assets will appear in manufacturing. As accomplishment becomes added automatic and that automation allows for tighter tolerances on the items getting built, the ability and bendability of abiding allurement motors are decidedly admired traits. Many manufacturers will amend their systems in adjustment to yield advantage of these attributes.

Common stone disease

1, the key is to rust prevention rust stone processing after surface treatment to be effective, in order to prevent the oxidation of iron minerals seeping surface, the general use of oil-repellant. Mainly deal with rust rust remover, but mostly due to the acidic rust agent, so not acid landscaping stone, such as marble, dolomitic, shall be tested prior to use, if necessary, add water to dilute.

2, water spots, wet marks prevent water Banzhu If the resin is injected so that the stone waterproof, moisture in the air to block and stone or cement internal exposure to the substance, reduce the chemical reaction conditions. If the use of treated water Banzhu penetration dye to change the original color of the stone, "wet marks quit" can be regarded as a major problem in the international stone tile conservation area.

3, white bloom, commonly known as tears prevent white bloom mainly in the stone processing with penetrating protectants for stone six-sided protective treatment. Processing Bai Hua phenomenon is mainly rinse the stone surface has been cleaned, it was rendered neutral, dried and then on the stone surface and joint conservation process. Rust agent and detergent should be used hyperoxia, gentle formula to remove rust stains on the stone, tea stains, straw stains, macular stains and metal oxides, must not harm the stone. http://www.stonegroupon.com/

If serious damage stone surface gloss disappearing phenomenon. If you encounter such a situation, you need to use Du Bishi polishing powder + F66 really light polishing agent. Polishing powder contains an oxidizing agent such as fine particles of aluminum oxide or tin oxide, the main ingredient containing a surface active material is not acid-containing oxide. Hand polishing suitable hotel building bathroom, kitchen area, surface, and polishing machine is used for large area surface matte area.

Decorative Stone Shop skills

When consumers buy decorative stone, often do not know how to identify its quality. Marble, landscaping stone, slate is a decorative stone in three main categories, which include natural decorative stone more than 99% of the species.
Choose decorative stone look Appearance:
Commonly used decorative stone mainly marble and granite.
Generally, marble texture and delicate, pattern varied, colorful, easy processing and finishing, but low hardness, poor wear resistance than the granite. Mainly used for interior floors, walls, window sills and cylinder finishes.
Granite is characterized by compact structure, water absorption is very small, hard, high strength, especially compressive strength of up 1200-2500kg / cm. Since the main mineral composition of stone tile strong resistance to acid, therefore extremely corrosive acid, alkali erosion class also has a strong resist force. http://www.stonegroupon.com/
Granite difficult to weathering deterioration, the appearance of color can be kept for more than a century, so much used for exterior finishes. In the air because of its strong ability to resist acid, higher than the marble hardness, wear resistance, the durability of marble, terrazzo and other stone can not, and therefore is an ideal architectural natural stone. Compared with marble, granite and less variation in color and pattern, but there are more flexible in terms of the texture changes, but appears to be more solemn and classical in the overall feeling.
Quality depends on the selection of decorative stone:
Stone material should be uniform and complete avoidance dark crack, black scar and color problem.
1. Note that the composition of the stone, avoid products containing excessive iron sulfide, iron oxide, and carbonaceous clay and other harmful substances;
2. Note that the radiation level stone;
3. Note the stone whether they contain mineral ingredients high coefficient of thermal expansion, thermal and electrical conductivity, in order to avoid cracks, thermally and electrically conductive dangerous.
To consider the selection of decorative stone Durability:
We should try to use the stone pore distribution, small aperture, low water absorption, high hardness and compressive strength. It should be noted, although higher than the major strength of the stone, but will increase the load of the structure, it will reduce the intensity and seismic capacity of buildings.

Stone describes selected

In the selection of the stone when the first, do not have cracks, second, do not have variegated lines. Transparency of white marble is better, but it will compare Mottled appear; and more white Greek marble, mostly do not have cracks, nor have variegated, so I chose to do the stone is an important part of the sculpture.
Stone selection turned out to be the same as the child's education, individualized. Through the heart of the selection, and then after a carefully crafted, into the works in the garden, it seems only natural, lively and elegant.
Inside stone field, carving techniques it is saying the use of materials, selection is very important part. For example, I want to cut a female body, you need the kind of soft feel. Western female body is very beautiful moment, because they are very beautiful marble, so for the moment the female body is very appropriate. If you want engraved farmer, get a stone Bai Bailiang light of light, that farmer looks terrifying, not the kind of rustic feel, so we will choose Guanyin rocks, stone green bucket This rugged stone.
Each stone hardness is not the same, of course, the hardest diamond, its hardness is about 10 degrees. In our engraving used, granite probably be the hardest, may be about 6,7 degrees; blue bucket mainland Fujian stone is stone, there are also about 5 degrees; marble carving in general, probably only 2,3 degrees only; Guanyin rocks is 2,3 degrees, the Goddess of Mercy is not the same rocks with marble, marble texture has a direction, a bit like a stick. Guanyin rocks with bluestone, a bit like concrete, it is a crystalline one, so it has no direction.
Aurora marble stone belongs to class, but it is relatively small quantity, like many of Milan church sculpture is carved from this stone, it's a bit like Hualien Rose Stone.
Zhu gravel belong sandstone, which is the Middle East's stone, the famous Heidelberg, Germany, the use of building materials is this stone.
Featured sand rock is that its structure is very loose, it is very coarse particles, in the middle of a structure with a structure which, with a magnifying glass to see, it is a hole in a hole, so this stone with fire to burn, it does not It will crack. This stone texture is very soft, hand rub a rub, you can put it particles rub down, but you do not move it, it can put a hundred years will not fall.
Bluestone pores do not like rough rocks Guanyin, its hardness up to 5 degrees, it is more often used in the temples of Zhu.

How to prevent stone weathering

Whether it is natural stone or artificial stone are becoming widely used in modern construction industry a class of building stone products, and whether natural or man-made stone products stone products, which will inevitably occur in the course of
Weathering phenomena; weathered stone by stone usually refers to the natural environment in a variety of factors erosion leaving the stone disintegration, especially for outdoor decoration stone, once weathering phenomenon, then life will shrink
Short, then the process of how to use the stone to prevent weathering stone? It had weathered stone from factors initiate discussions.
1, lower plants role:
In water at a temperature suitable conditions, moss, mold and other organic matter sporangia with attached stone surface, began to develop the growth of the stone surface to form a wide variety of organic stain, these organisms in order to survive, and empty
Gas carbon dioxide, sulfur dioxide, nitrogen dioxide and other substances to struggle to change the surface texture of stone. In addition, after the death of these plants form organic acids and water accelerated aging stone, the stone erosion phenomenon.
2, ultraviolet radiation:
Stone itself has many pores and capillaries smaller capillary phenomenon is more significant. Therefore, the stone water, in the sun (UV) radiation, the rate of evaporation of moisture in the pores of the stone will accelerate, with water in the rate of erosion of the stone erosion of the stone material will be increased, thus caused by aging stone.
3, cleft stick effects:
Adhesive is a stone installation method, which remains in the adhesive surface of the stone due to the effects of aging of the adhesive cementation mineral stone produce relaxation, the stone interior relaxation, easy to peel off the surface, thereby accelerating the aging stone.
4, thermal effects:
Stone expands due to the heat during the day, at night the cold and contraction, resulting in thermal expansion and contraction phenomenon, and stone contains many different minerals, its expansion coefficient, and granular erosion or lump disintegration occurs.
5, the water freezing and thawing:
Freezing and thawing of water can make stone weathering: temperature dropped to 00C below the water freezes, causing ice water after the rapid expansion of the stone, the stone disintegration fragmentation.
Therefore, in order to prevent weathering of stone, you have to take appropriate measures in accordance with the physical causes of weathering were the only way to prevent the use in the construction industry weathered stone.

Stone Fence applicability

Stone railings stone railings short, stone barricade is safe initiative measures on bridges and buildings, requiring strong, and beautiful to watch. Is a professional production and sale of stone barricade the company, the company can be carved according to the requirements of users a variety of stonework, can also be customized in various sizes bluestone, marble, granite and other stone railing. Stone barricade at the beginning and end of each group will be complemented by a mix of drum stones, concise overall better atmosphere. Shelter building, railing should not have too big a gap or climb the rungs.
Stone carving is our Chinese culture for thousands of years, is the crystallization of the working people, from ancient times to now stone reflects the milestones of social development. From the formal point of view, it can be divided between the sections of stone barricade continuous type two. Most of the back fence of bluestone carving in the shape of simple atmospheric contour lines. Modeling, stone barricade pillar stigma mostly cloudy pillar and two vases, some carved into lions, elephants and other auspicious, some carved into the shape of Chinese zodiac animals.
Common types are: wooden railing, stone railings, stainless steel railings, iron railings, forging stone railings, cement railing, composite railing. The more positive bluestone steeplechase bas-relief carving of some content Geely pattern, flowers, auspicious mainly sculpture department of cultural history and stories narrative theme. Staircase width over 1.4 meters, should be set up double-sided handrails, greater than 2.4 m, a railing to be added in the middle.
Stone barricade generally consists of pavement, bluestone steeplechase, pillars three departments.
Railing height depends primarily on the use of objects and places, the general high 900 mm; kindergarten, primary school staircase railings handrails can be built in the form of dual-channel, respectively, for both adults and children; the discretion of the heightening at high risk.
Stone barricade stone railing in a major representative of bluestone is a blue-gray marble texture more solid, is characterized by particularly resistant to weathering, it has been widely applied to large stone arch, stone carving and other construction projects.
In use since the stone barricade separated oriented role of the divided region boundary and clearer, designed railing, it is a decorative significance. The former by the column, handrail and ledge composition, handrails supported on pillars; the latter has a continuous handrails, the handrails, balusters and base composition. Stone barricade constructed of materials are wood, stone, concrete, brick, tile, bamboo, metal, glass and plastic.

Stone tiles make home renovations substitute more environmentally friendly and durable

Now living standards improve, people not only in terms of the requirements of both home improvement fashion look good, but are increasingly seeking more environmentally friendly, so that in terms of home improvement do not know what material re-election as well, for this situation, I compiled some information for friends as a reference.
Because previous performance deficiencies, the bathroom is wallpaper, art coating forbidden, now may not be the same. Look up and down the flow of water through the wallpaper has this, and no softening, loss, damage marks.
Not afraid of water wallpaper
Because previous performance deficiencies, the bathroom is wallpaper, art coating forbidden, now may not be the same. Look up and down the flow of water through the wallpaper has this, and no softening, loss, damage marks. According to reports, this wallpaper thicker than ordinary wallpaper, but soundproof, mold, insulation effect will be better, be regarded as a wallpaper border of environmentally friendly materials.
You can replace the wallpaper tiles
Wallpaper to "spread" to the bathroom, and tiles are going way toward the bedroom, the walls of this figure is not with wallpaper paste into, but posted with European-style wallpaper tiles. Compared with imitation tile wallpaper wallpaper glue can be used with less toxic gas, relatively more healthy, but tile gives a more cold feeling, applies only in the local space.
Marble and tile Composite tile
If you have recently teach each tile brand showrooms and see exactly the same surface texture and marble tiles, you do not think they are all imitation stone tiles, and some may be a composite tile marble veneer. This composite tile is made of natural stone and tile adhesive layer blanks made thinner than natural stone, lower installation costs and make use of natural stone resources is maximized.

Stone walls choices

In the curtain wall design, the need to draw based on stone size, color, materials and other factors of the detailed structural detail, and follow the complete mechanics checking the seismic design codes, compression, and other relevant parameters related nodes to ensure application of stone walls security and stability. General on the stone of choice should be based on the characteristics of the stone walls in indoor and outdoor, in accordance with detail elevation and each node, for its strength, water absorption and vibration levels and other parameters of the mechanical calculations to determine the stone selection, priority should be given characteristic nature stone products, color, texture and other physical properties and, combined with walls of sub-grid form, construction cost, design and layout required to reach the best overall design of the building stone.
In high-rise curtain wall design, for the calculation of the mechanical properties of stone walls associated nodes, we require a combination of structural curtain wall design mode, the connections, material properties and national industry standards of conduct required to complete the calculation of mechanical curtain system. Which can be divided into the following areas:
(1) carry the load is determined. Generally, in determining the load, you need to consider the weight of the stone, wind loads, seismic loads, and other loads forms, maintain effective load transfer structure, for uncertain load, can be determined according to the national standard projections and simulations.
(2) Stone force calculation. Before calculating the stone by force, need to determine the load in the form of stone and stone dry hanging way to determine the model of the stone walls, the stone walls of the load-bearing manner, security, and make calculations. In addition, we also need to make the stress analysis of the stone itself, including the physical properties of stone and indicators, complete the calculation according to the different characteristics of the safety factor of stone.
(3) Stone bending, shear resistance checking. For anisotropic stone, stone walls flexural checking the relevant section can be divided into two cases, one occurred in the largest stone plate bending stress point in the other direction of the stress is zero, as long as the maximum stress is less than in the corresponding direction on Stone allowable stress the stone plate bending performance to meet the requirements of their own, and vice versa is not satisfied. The second is the occurrence of the stone plate in the maximum bending stress point in the other direction is not zero stress, then we must also be considered when checking the stress. Then you can apply the theory of internal friction checking. When checking the shear strength of the stone, we need to be calculated based on the parameter checking the thickness of stone, hole depth.

Paving stone floor space so that you feel unexpected mood

The interior decoration stone interface used to lay the ground-based, supplemented by wall decoration. Common ground laying stone granite, marble, quartzite, etc., which have a single way of decoration stone decoration and a variety of stone mosaic decoration, single stone decoration on the ground often after laying in accordance with the same kind of planning is not the same way, and with the Stone texture combined together to form a highly decorated effects. A variety of stone mosaic decoration is not the same standard, the type of stone-paved ground, multi-used in the construction of certain places, forming a special role for the interior to add a lively atmosphere, full of sentiment, you can get unexpected Space mood.
(1) a single stone decoration
Single stone laying on the ground in the interior decoration elegant color and texture "91. In the public space, the general needs of color to soft, bright, resplendent and unadorned natural personality, especially hotels, indoor timber church was seeking beautiful, so generally used warm granite or marble, that preclude the use of color is dark granite, such as red Indian red, red South Africa; perhaps yellow marble, such as beige beige series probably like Anna in the office is simple and clean elegant, private construction indoor demand is reasonable to lay a small area, so use the stone to be arbitrarily divide the plane according to the size of the space, so that the entire plane is more personalized.
In public construction, although not the same color and material laying on the ground stone gives the same visual experience and mood, but a large area on the ground stone division, the general selection criteria square, so make the entire plane is generous and stable.
(2) a variety of stone mosaic decoration
Stone parquet floor renovation is a major renovation the most widely used method, it should be based on a different place, a different area and not the same as the space environment and planning. In addition, interior decoration mosaic stone floor plan also ponder stone types and standards. Generally, thinking to the construction of convenience and cost constraints, stone mosaic decoration planning to use some of the existing stone to form concise, orderly brief picture. Sometimes in order to set off the surroundings, outstanding stone mosaic picture of elegant artistic personality and ethnic characteristics, can take a variety of curve and line constitute the more cluttered graphics.
Parquet floor decoration can make natural stone texture and color sense perfectly reflected, material and color more vividly reflect the wonderful stone with noble, elegant personality.

Causes of discoloration in natural stone interior decoration

The so-called marble refers to the deposition of carbonate rocks or metamorphic rocks, there are marble, dolomite, limestone, sandstone, shale, and slate. Interior decoration of natural stone discoloration cause analysis, since the decorative stone is a natural product, every piece of sheet metal pattern, color characteristics are not the same, must parquet (color), so the pattern, color gradually extended transition, in order to achieve the overall color reconcile.
Interior decoration in a natural stone color Causes:
Natural stone color is colored by the minerals in the presence of ions such as iron, copper, nickel, cobalt and other heavy metal ions, and presented, these heavy metal ions in the water, the active substance in the air, will produce color change brought stone color.
Interior decoration of natural stone discoloration Cause Analysis II:
For example, the role of iron ions in the water will generate iron oxide and iron hydroxide, its color is yellow, thus the Diao yellow material; and if copper ions and carbon dioxide, water, basic copper carbonate produced by the reaction, the color is green, thus making Pan edge of the stone surface, seem faded and dull. This is the main reason for the stone color.
Interior decoration in natural stone discoloration Cause Analysis III:
Pale water brush, dry stick stone, terrazzo and other decorative surface layer, but also because of the mere mention of which stone plant produced (of course there due to the incorporation of color discoloration caused by) such as green water brush stone because of its green stone ballast bag prime ion stability is poor, it will fade after a few years of use, coupled with the surface area of ​​the gray and lose their decorative effect. Color stable rosin gravel stone, white stones, black stones, etc., so the selection of gravel should be selected color stability of species.
Interior decoration in natural stone discoloration Causes four:
Also with the mere mention of natural stone materials and related structures of stone. In general, the silicate stone (such as granite, etc.) for its crystal structure closely at atmospheric role of small color change, thus often used in outdoor decoration.
Interior decoration of natural stone discoloration Causes five:
Phosphates Ishimura (such as marble, quartzite, etc.) because of the crystal structure of loose stone ingredient calcium carbonate reacted easily with acid rain, low generation intensity, soluble in water, gypsum, so that the polished marble surface becomes rough porous, discolored and dull. So carbonate stone generally should not be used for higher durability requirements and historic, decorative monumental buildings.
Nine positive net Stone cautions, natural stone care maintenance needs attention to detail, consumers often waxed to protect the surface of the stone, but the wax covering the pores in the surface of the stone will be blocked. The secondary maintenance, adhering to the stone surface of the wax becomes secondary protective wax into the stone inside the barriers, then, cement or adhesive between the stone and the ground will be wet or chemical reaction slowly because "invasion" Stone's body, causing the stone base and anti-stain and other diseases.

Five elements stone conservation

Many people in the decoration of their new homes, in order to appear gorgeous style,stone for building will be used to do some natural stone modification. But these stones during maintenance, do not need to remember five, or make the stone surface erosion and destruction.
1, thoroughly clean to keep clean
Whether hard stone factory texture or soft texture of marble are resistant to long-term ravages of sand and soil particles. So either do a thorough dusting and cleaning.
2, regular maintenance luster
Alone dust, clean the stone can not make beautiful luster continued to maintain reclaim. Please be sure to regularly send professional companies to do maintenance and gloss renewable maintenance work. http://www.stonegroupon.com/
3, immediately remove contaminated
All stones have natural pores, pollution (oil, tea, coffee, cola, soy sauce, ink, etc.) can easily penetrate into the stone house along the pores formed nasty stains. Once down on the stone sources must be removed immediately to prevent infiltration of stone pores.
4, often dry and ventilated
Stone fear of too much humidity. Stone will produce water vapor hydration, hydrolysis and carbonation effect, resulting in water spots, Bai Hua, weathering, erosion, yellow rust and other diseases, destroy the stone. Therefore, to always keep the stone dry and ventilated, waterproof.
5, regular protective treatment
To ensure long life stone, block the penetration of water and pollution, must regularly (depending on the type of stone and Protectant best quality from 1 to 3 years to do 1 to 2 times treatment) protective treatment facilities to do. Quality protectant must pay special attention. Shi after doing must be able to maintain stone breathable and waterproof, stain resistance. You must not use unsolicited repellant, so not only reach the protective effect, but increased the stone maintenance problems.

Stone walls favored by the residential market

In recent years, due to its noble stone walls, beautiful texture liked by the public. At present, the city has used widely in stone curtain walls, glass curtain walls, metal curtain.
It is understood that the stone walls are usually composed by the panel and the support structure, the main structure does not bear the load and the building envelope. General to take the first steel for the keel, fixed on the main building, and then hung on the keel panel installation. Because this decorative manner with respect to other decorative stone method, although the cost is slightly higher, but security is high, not easily fall. Secondly, stone walls not only look beautiful, but is building a whole plays a good role in energy conservation and environmental protection, because it is equivalent to the entire building put on a coat.
"In recent years, several stone walls special inspection found that some developers or construction units, in order to reduce the project cost, the thickness of stone inadequate, excessive weight deviation profiles, stainless steel pendant non-compliance, structural adhesive glue replaced with marble and other issues, there is a security risks. "Taizhou City Construction Project Quality Supervision Station Office, 任陈琦 told the author, now combined with the requirements of the project quality management two years of action, demanding the implementation of the city Zhijianzongzhan stone wall construction plans review system, the construction program and expert verification system in the future, strengthen the process of curtain wall construction supervision and management, to ensure safe and reliable construction quality.

Great stuff parties who different views on the stone

Stone resources of nature through hundreds of millions of years before the formation of the human left nonrenewable materials, once used up no longer have. Stone as a natural thing, for various reasons, there are many undesirable places, which led people in the understanding of the formation of a variety of stone views, in the treatment of stone beauty and defects can be described as benevolent see benevolence and the wise see wisdom.
A British merchants saw the stone fireplace with a yellow rust in Omi when working out, looking at the above rust stains issue "This is gold," the lament. However, if it were our domestic professional stone people, they must be prepared to handle these materials as waste. Phrase sigh, let us find people of Eastern and Western views on the stone was so flawed a big difference. The rust point defects Stone described as "gold", which is only humorous people in the West will have such a fitting metaphor and description. Western Stone awareness of the stone, they are the use of natural stone color to create a natural posture of color, the beauty of nature, to create a kind of only a few people can understand and comprehend the raw, rugged beauty. With many black specks of yellow sandstone, German customers regard him as a valuable raw material stone processing. The Chinese stone in the processing of this material with many black specks are not completely clear, resulting in a large waste materials.
In our eyes we do not think with the material, in the eyes of German customers has become the meat and potatoes, which is west of Stone who was born naturally, take in the natural stone of views and understanding. Perhaps this is the Western Stone Industry sources for limited natural resources, material exigencies of pity, perhaps reflect those unique Western Stone aesthetic point of view. Different countries for natural stone understanding that much difference. We are for foreign manufactured stone product testing standards must not be applied mechanically relevant domestic stone products to test these products, otherwise we are likely to give their business to avoid unnecessary losses, resulting in the production process downtime to be expected.
The reason why thousands of years of natural stone popular worldwide, and more and more loved by the public, a very important point is that the stone its natural, simple, no demon not brilliant style. Throughout the rest of the world with a decorative stone buildings, luxury ornate those who have, those who have the makeup elegant; perfect those who have, riddled with those who have; hue uniform who have, those who have disorganized. Designers from its own design concept and intent of view, the use of natural stone features dotted with buildings, so that the building shines with a unique aura. Perfect beauty is the beauty of things in the highest level, but the thing of beauty but it is incomplete has other beauty charm, is a do not know, which do not understand, meaningful and timeless beauty, you can do with your imagination to comprehend, to experience.

Stone industry business model change

Stone industry after decades of development from the amount of "small, scattered, chaotic," gradually shift to changing standards. Although China has a long history of stone, but the development is slow, not as abroad has a strong strength stone industry. Domestic stone industry, "feeling the stones" at the same time learn from foreign development model, while development while exploring the road of development suitable for the domestic market. At present, the poor economic situation in the background, stone industry to accelerate the pace of reform and innovation, to change the development mode. Yunfu, head and Xinjiang vigorously building stone industrial park, complete stone industry value chain, the production, processing, logistics and marketing to unify the formation of industrial clusters. Some stone people thinking about how to improve the development of the domestic stone industry, improve the competitiveness of domestic stone enterprises.
Big brand is the development of the Road
Now alone no longer meet the new situation, the chain, pushing development, create big brands, to build a large platform, take the initiative to go out, it is the next road development. Internet to subvert the traditional market model, sales of thinking through the Internet and other Internet B2B realized towards the 2.0 era stone market. Stone professional website through market analysis to explore the formation of products, promote sales, share and win-win, personalized service and information feedback. Small business is hard to win in this kind of thinking that only the creation of big brands to survive in the Internet mode.
For enterprises in terms of traditional stone, the stone is extremely difficult in a short time to market of new products, and accepted. With that in mind, a big brand new very meaningful for new terms. If the market environment is superior, but also brought together most of the new products on the market, so from time to time to visit the elite team of designers organized exchanges, new sales is not a problem.
Stone enterprises to establish brand thinking, "small" is certainly flexible, but in the economic tide, it is difficult to withstand storms, it must be eliminated. Big brands like aircraft carriers and competitive. Faced with the plight of the self-generated power can guarantee not to be overturned wave.
Chain business model will become the mainstream
Stone large plate market has developed more mature, "Stone qualitative change" has come. Stone large plate market has experienced extensive, platform, segmentation, the next will gradually render intensive. The intensification that is looking for partners, pushing development, to achieve resource sharing, complementary advantages. In the new normal, enterprises should hold together for development, in the form of "big mall" to go out, both components display market, but also improve survival.
Establishing industry value chain, not only serves the upstream and downstream sales, but also supply services other projects. Stone business as producers and sellers can not face the majority of the market everything. Specialization and segmentation of the market needs, so indispensable partners. Fast-food industry chain mode of operation, can quickly locate the market, companies need the stone in such a way. Companies looking for partners in the stone market chain, quickly capture the market, complementary advantages.

Stone Care inseparable stone protection!

Marble floor polishing some projects after the renovation of the explosion grain, peeling, black pinhole phenomenon, the effect of after care might as well not care, to stone care industry has brought great negative impact. This happens study the fundamental reason is that people do not understand stone stone care lithology and physical and chemical properties, did not grasp the essence of stone care, and will not use the correct stone protector in stone care. Stone care because no proper use of protective agent will cause a lot of problems: water spots, rust yellow, efflorescence, mildew, polishing is not ideal, freezing and thawing conditions, etc., and so the problem was mainly due to contaminated water or liquid substance caused by stone . Natural stone is a kind of material having a microporous structure, there are many invisible pores, which makes water and contaminants can easily invade the stone, so long as the frequent contact with the liquid substance, will the above phenomenon. How to solve these problems, in fact, very simple, that is selected, with good stone protector!
The above are some of the questions put renovation will occur in property projects, we often will encounter such a situation stone floor entrance, bathroom, pantry, after a period of time, there will be water spots, rust yellow phenomenon. This is because of pollution caused by water, if we know the stone protector can effectively choke the liquid on the stone erosion, when we settled on the well protective treatment, it is possible to prevent the emergence of these phenomena, they will not face follow-up Some symptoms of governance issues. There are more similar cases from stone care proved not stone repellant.
? What is it Stone Stone Care Protectant national vocational qualification training materials are given specific definitions: stone Protectant is to prevent the generation of natural stone Bai Hua, water spots, rust and other diseases phenomenon, can effectively reduce the stone water absorption, improve Stone stain resistance and corrosion resistance of the solution.
Since the stone protector is so important, then how do we protect it? First, we must understand there is a stone Protectant grade, there is a national standard products, we should select in the construction of first-class products by the National Testing more products ; there are a lot of stone Protectant classification, to understand these classifications, we can make better choices and application specific work. For example, stone protectant by function with anti-oil type, and waterproof two, then the restaurant area stone protection during processing, we know should choose anti-oil-repellant, because such areas as the restaurant's main oil Pollution. We should also remember the 12 words in the construction repellant essentials: clean, dry, grade, adequate, uniform, and health.

Our artificial stone production capacity of about 100 million square meters

Recently, the third national seminar on the development of artificial stone industry in Henan Nanyang held and released in 2014 artificial stone Report.
According to incomplete statistics, China Stone Association research report, the number of national artificial stone companies in about 120, of which, Fujian Nan'an existing artificial stone Enterprise 40, the production line 60; Yunfu existing artificial stone Enterprise 16, the production line 34 ; Hezhou existing artificial stone Enterprise 4, the production line 13, the next two years will reach 34, the production line will reach 122; Henan Neixiang existing artificial stone Enterprise 5, the production line 11. Artificial stone companies, mostly granite production enterprises, accounts for about 80%, mainly concentrated in Fujian Nan'an, Guangdong Foshan, Zhaoqing and Yunfu City; quartz stone production enterprises accounted for about 20%, mainly concentrated in Guangdong Province. Fujian Nan'an artificial stone Enterprise annual production capacity of about 50 million square meters; Yunfu artificial stone Enterprise annual production capacity of about 11 million square meters; Hezhou artificial stone Enterprise annual production capacity of about 10 million square meters, plans to reach within the next two years 150 million square meters; Henan Neixiang artificial stone Enterprise annual production capacity of 10 million square meters. According to estimates, China's annual production capacity is about man-made stone 100 million square meters. Among them, the artificial quartz stone production capacity of about 6 million square meters.
According to customs statistics, the United States is the largest export market of artificial stone, as of November 2014, with exports amounting to $ 93 million, followed by Thailand $ 34 million; in addition, Brazil, Britain, Singapore, Iran and Malaysia, exports also are more than 10 million US dollars. Shenzhen, Guangzhou, Xiamen and Shanghai is the largest export of artificial stone 4 Customs District, which, Guangdong accounted for more than 70% of man-made stone export share.
Research report also pointed out that the vast majority of our country artificial stone production equipment is lagging behind, a considerable number of product quality is not high, blindly rely on low prices to seize the market, but there are a small number of enterprise product quality at or close to international standards, and in the international market place. Overall, the artificial stone production enterprises with product development capabilities of enterprises very few, most enterprises do not have the product development capability, lack of professional scientific and technical personnel, employees generally are not high quality.

Thin natural stone composite panels Classification and Advantages

Thin stone composite panels composed of two or more different plates bonded together with adhesive. Natural stone surfaces, the substrate is ceramic tile, stone, glass or aluminum honeycomb like.
Second, the classification
1) classification according to the substrate is divided into:
① stone - aluminum honeycomb composite panel
② Stone - hard substrate composite board
a) Stone - Tile composite panels b) Stone - Stone composite board c) stone - glass composite board d) Stone - Polyurethane (insulation material)
2) Press shape divided into:
① P plate
② arc boards
3) Press the surface material surface processing were divided into:
① mirror panels
② matte panel
③ crude panel
4) divided by class:
① class product
② First grade
③ qualified products
Third, the implementation of standards
JC / T 1049-2007 "thin natural stone composite board"
Fourth, the advantage
Light weight: the thinnest marble composite panels can only 5mm thick (with aluminum-plastic composites). Conventional composite tile or granite, also only about 12mm thick, transportation only saves a lot of costs, under the load of the building have limited circumstances it is the best choice.
High intensity: the marble and tile, granite, aluminum honeycomb panels and other composite, bending, bending, shear strength significantly improved, greatly reducing the transportation, installation and use of the process in the breakage rate.
The ability to improve anti-pollution: general marble original board (whole body board) during installation or later use, such as wet cement paste, probably after six months or a year, marble surface of a variety of discoloration and stains, very difficult removed. Composite plate because the floor is more hard and compact, as well as a thin layer, to avoid this from happening.
Easier to control color: marble composite plate is used because the original board of 1m2 (whole body board) cut into 3 or 4 into a 3m2 or 4m2, and its pattern, color is almost 100% identical with the original plate, and thus more likely to ensure that large-scale use .
Easy installation: because with the above characteristics, the installation process, regardless of weight, easily broken (strength, etc.) or separations splicing have greatly improved installation efficiency and safety, while also reducing installation costs.
Break through the taboo: marble decorative parts, regardless of the external walls, floors, bay windows, porch, desktop, and so on, the ordinary original board (whole body board) is not a problem, except the ceiling either marble or granite, not any decoration company I can not dare to take the risk. The marble and aluminum panels, bonded aluminum honeycomb composite board decorative stone to break this taboo subject. Because it is very light, weighing only 1/5 to 1/10 of the whole body board. To use decorative stone ceiling This is it.
Noise, moisture: made of aluminum honeycomb panel and marble composite board, because with equilateral hexagonal core made of hollow aluminum bees have noise, moisture, heat, cold performance. Thus, these features is far beyond the whole body panels do not have the performance characteristics.
Energy conservation, energy: Stone aluminum honeycomb composite plate because there is noise, moisture, thermal insulation performance, and therefore, can greatly reduce power and energy consumption after installation indoors and outdoors.
Cost reduction: stone composite material is thin due to lighter, saving on transportation and installation of a part of the cost, but also for the more expensive varieties of stone, have varying degrees of low price than the original cost of the finished plate after plate made of composite board.
Features advantages, there are practical advantages in performance comparison of both natural stone marble composite panels, which also determines the development trend of sustainable future markets. On the international market more and more widespread use of countries and regions, also verified the market trends marble composite board.

Other processing techniques cylinder shape

In addition to the above described common pillars, Roman and twisted columns, there is a polygonal body pillars, its cross-sectional shape of a regular polygon. Polygonal body pillars into polygonal cross-section and other body pillars and tapered polygonal cross-section ranging from body pillars. Polygonal body pillars have column bases, column caps can be divided into a whole column or column splice several parts, whether or not spliced ​​Max size is determined according to the length of the column and processing equipment.

     Processing polygonal body pillars process than for processing the other pillars simple, circular saw, bridge cutting machine and other simple stone cutting device is equipped with a rotary cylinder, fixing accessories, can be processed polygonal cylinder body pillars. Process that saw reciprocating motion, with blocks car (circular saw) or saw power head itself moves back and forth (bridge cutting machine), you can complete the cutting edge between the cylindrical surfaces of the two planes; change saws the vertical height of the sheet position, you can adjust the processing of different diameter polygonal body pillars; aliquots rotating body blanks can be processed plane between the other two edges until the completion of the entire polygonal prism stone processing. When using the equipment for processing, should be noted that, as long as the pillars of the polygonal prism maximum circumcircle diameter and the largest sum allowance (blank maximum outer diameter) equal to the maximum distance between the blade and the work surface, polygonal body pillars The process can be achieved. Sometimes in order to get more working space, you can use a small diameter diamond saw, but need to pay attention to change the drive motor speed, so that the small diameter of the blade also work at a reasonable speed cutting line.

     Use with a lathe attachment versatility of CNC machining centers more easily processed polygonal body pillars, simply rotate the cutting direction of the diamond blade 90 degrees to make it consistent with the cylinder axis direction, according to pre-programmed machining program can be completed more automatic processing prism pillars. CNC machining centers on the use of a cylindrical end mill power head, can also be processed polygonal body pillars column bases, column caps, and is an integral pillar of processing.

     You can move back and forth in the beam, the blade can rotate 0-360 CNC lathe, it can also be easily processed polygonal body pillars. If this type of CNC lathe equipped with a cylindrical end mill power head, it can also be processed polygonal body pillars column bases, column caps, but with a plinth, overall stone column cap processing, preparation and processing program is very simple. After using fixed beams CNC lathe can be processed polygonal body pillars, pillars and even the whole, it must be equipped with three-dimensional laser scanner, making the body pillars polygonal model, by scanning of the model, and the preparation of a machining program, you can processing, and this configuration is currently rarely used.

Hollow rotation system for the processing technology

Hollow rotary system products generally refers to the shape of the outer surface of a rotating hollow vases, flower beds, water dish hollow cylinders and other products, bus rotors can be any shape of the curve, but also allow the outer contour curve engraving.

     Manual lathe can be processed internal surface of the hollow body of revolution, artificial carving method is also a means of processing the hollow body of revolution, but the poor quality of products produced using these processing methods, low processing efficiency. This section describes how to use CNC lathe and CNC machining centers hollow rotating body approach. The use of CNC lathes, CNC machining center with multi-purpose lathe attachment can be processed any complex curved shape of the inner surface of the hollow rotary system products.

     Machining shape surface without vase carved hollow rotary system class product, you can use ordinary lathes, CNC lathes or CNC machining centers, multi-function devices with a lathe accessories, but must be equipped with special cutter lathe machining the bore surface of power head. Vase class manufacturing processes hollow rotating body include:! Blank selection and processing of the end face bearing hole machining - Products outer surface contour forming - inner surface of the molded article - Polishing - Cleaning - Inspection and packaging.

     Selection --- most of the blank type vase hollow body of revolution is marble, there are a small number of granite vase. In addition to marble texture soft, easy processing, the selection of marble vases material as an important reason is that the marble has beautiful patterns, can produce unique charm of artistic effect after grinding and polishing.

     Blank machining vase --- rotary type hollow billet is generally cylindrical in shape, it can also be processed into a square-type cylinder. Because in the molded article contour, using square billets need to remove the extra large number of stone, occupied CNC equipment a long time, is not conducive to reduce processing costs, so as far as possible using a cylindrical blank. Use CNC Wire Saw can cut directly from the stone blocks out of the cylinder blank; you can also use circular entrenched machine is divided into square blocks blank, and then use ordinary lathe, manual operation processed into a cylindrical blank blank square or approximately Vase Hollow Rotational contour of the blank; if no NC rope saw or lathe, or at least should use the blank circle entrenched machine processed into cylinders regular polyhedra section.

     --- End face bearing holes do not need the support structure generally applies to the processing of hollow bore vases solid class products. When machining a hollow bore vases class products, because of the need internal holes forming, then the need to cancel the rear of the support shaft, otherwise it will impede the hole machining, it is necessary to adopt boss holding structure. Processing of the support structure of cylindrical processing requirements see the content.

First detected again decoration

City Interior Quality Supervision and Inspection Station of Cao Jian said that if members of the public worried about excessive use of radioactive materials, it should focus on checks from the material procurement, rather than waiting for renovation work was completed even after the body had been violated were detected. Because radioactive hazards generally from stone, tiles, sanitary ware and other jewelry embedded fixed, in the house after the renovation, because the environment there are other materials, data can not be measured by a single material. To accurately measure it, you have to knock off a piece from the finished product, to the laboratory, but this method is clearly not feasible.

    How to check from the source? City Environmental Quality Supervision, Inspection Station, the official said, should look for three "chapters." That consumers before buying these materials, should first ask businesses to produce these materials inspection report, there should be three "chapters" on the report, namely Chapter round testing organizations, oval CMA chapter CAL chapter, at the same time report It should also be noted on these materials, "tested qualified" conclusion. City building materials and component quality inspection stations, vice president of engineering master Hui pointed out that the material used for home interior decoration materials must also be class A, because only such a material is suitable for civil interior surface, and businesses should also show consumers proof Class A decoration materials.

New "standard" regardless of Radioactive

In the city on the 15th of this month will be formally implemented "Shanghai Residential decoration acceptance criteria", the first sight for some materials may contain radioactive material in marble, granite, ceramic tiles, sanitary ware, etc., does not seem to make specific provisions. However, according to the "standard" drafting group leader, Shanghai Research Institute of Building Science detecting House Ming Gang, deputy director of the "standard" of the first part of the "basic principles" clearly states "housing decoration should abide by the laws, regulations and relevant regulations "," decorative quality of purchased materials shall comply with the relevant standards of product quality requirements. "While the national standard in 2002 start of the "building materials radionuclide limits

     GB6566-2001 ", then on supplies of natural radionuclides radium-226, thorium-232, potassium-40 and other radioactive specific activity limits were specifically defined. That is to say, the decoration on the radioactive material used also subject to the "standard" of the constraints.

Stone decoration before the first test

Myth one: deep-ray Multi-Color

    Some people think that the decoration stone darker, the stronger radioactivity. In this regard, experts have said that this statement is not tight. Although in general, as in the case of a class of white marble stone indeed rarely excessive radioactivity, radioactive malachite green, granite is relatively little more, but not necessarily a link between the color depth and intensity of radioactivity. Such as radioactive majority of black stone and will not be exceeded. The real decision radioactivity should be stone "birthplace" is the geological conditions of their origin determine its radioactivity.

Some people think that as long as it will certainly exceeded radioactive marble, experts say, it is not. On the one hand because it is a synthetic artificial marble, it is generally not contain radioactive elements, on the other hand is not even natural marble deeper the color will be exceeded. City Environmental Quality Supervision, Inspection Station last year had marble, granite and other 10 kinds of stone over testing, the results are all qualified marble, granite touches more than 40% of class A limit (ie not suitable for indoor decoration materials).

Slate Size test methods

Stone divided into two, one for one side polished stone, and the other two panel without grinding stone plane.

    (1) The flat side of the grinding stone thickness limit tolerance measurement method

     Vernier caliper with readings 0.1MM measured midpoint four sides. With the difference between the maximum thickness of the same block board and minimum thickness represents the thickness between the very poor. Contract floor thickness of 10MM, allow poor of plus or minus 1.00MM
   
    (2) the length and width measurements

     Steel ruler with a reading of measuring 1MM. Length, width were measured three straight, with the average value

Which election cabinet table?

Right now the cabinet table variety, generally with natural stone, artificial stone for building, fire boards, stainless steel and other categories. They have anti-fouling, anti-scald, anti-acid, anti-scratch surface material should have the basic properties. But their physical performance and price and other aspects have different.
Natural stone includes a variety of patterns of granite, marble, it is hard, anti-scratch performance is very prominent, and feel cold. More commonly is black and white two kinds of flowers,

But only in respect of white marble, its antifouling performance slightly less. Natural stone factory density, require strong cabinet support, and it is more than hard, lack of flexibility, such as cracks occur in case of whack, it is difficult to repair. Its cost varies with the different colors, most commonly used in several price of around 200 yuan a meter, are among the most affordable kind of countertop materials. http://www.stonegroupon.com/

Artificial stone is very popular countertop timber, it points to a seamless and seamed two kinds. Artificial stone adhesive seam up traces of obvious gaps, scratch resistance and anti-acid alkaline somewhat less certain. Its price in the 300 to 400 yuan / m. Seamless artificial stone using a material called methyl methacrylate, enrich its color, overall shape, there is no trace of seams, and repeatedly polished refurbished. General stains can be wiped off with a damp cloth or cleaner, but strong chemicals such as paint removers, to the light water containing acetone, turpentine and acid-containing cleaning agents can harm water into it, causing stains. The impact will be severe dent in the surface. Price varies due to domestic and imported, domestic prices in the seamless artificial stone 1200-1500 yuan / m on the right, but will have sold DuPont Corian 3000 yuan / m and down.

Fire board table is in the mainstream of the current market, it's anti-fouling, anti-scratch, anti-scald, anti-acid balance performance, color variety. Its base is MDF, the surface is

Fireproof materials and decorative veneer. Firewood has a high middle and low points, priced at between 300 to 600 yuan / m, we can say the price is more affordable. Compared with natural stone, fire board more flexible, will not blow and crack, its maintenance and repair and other materials is basically the same, but also very simple.

Stainless steel countertops clean and bright, the performance is more excellent. It is generally in the density of the fire board surface plus a layer of thin stainless steel plate, but with stainless steel cabinets waned in the retail market, it has not been good, the market is difficult to see the.

Countertop material directly affect the "whole kitchen," the cost of two million yuan of "Kitchen" usually use seamless artificial stone countertops, kitchen outstanding quality and decoration effects. Ten thousand yuan of "Kitchen" is more than a slit artificial stone, fire boards and other purposes. Natural stone cost varied, b

Stone type wall decoration process

(A) natural granite, marble wall structure and construction technology

      Natural granite, marble wall structure:
Natural stone is heavy, in order to ensure safety, the general approach of double insurance, ie plate with the primary connection with lashing wire, then irrigation mud mortar. Facing plates and structural walls interval of 3 to 5 cm, as grout joints, filling post every time poured height 20 cm or so, after the solid condensate continue perfusion.

      2. Natural granite, marble wall construction process:

      Primary treatment → installation grassroots sheet steel mesh → drilling → lashing plate → Filling → caulking → polishing.

      (B) the structure and construction technology quartzite wall

      Quartzite structure and construction technology glazed walls can be pasted with a similar approach. Quartzite high water absorption, to be soaked with water before pasting.

      Home decoration small size of local stone and artificial stone can refer glazed paste method.

Marble: Select skillful construction inspection

Marble material natural marble and artificial marble categories. Natural marble hard texture, color changing, shades, a variety of gloss, so the formation of unique natural beauty. Artificial marble lighter than natural marble weight, high strength, thin, corrosion-resistant, anti-pollution, better workability, can be made curved, surface, etc., to facilitate construction. But in the color and texture of natural marble less beautiful, natural and tender. For this reason, the choice of marble decorative materials, should take full account of their own in different parts of the overall decorative effect, such as walls, cylindrical, ground and the like; and marble polished plate with beautiful and colorful patterns, such as cloud-like pattern Qingyun Flying , it seems natural picture color texture. Marble is also widely used in high-end bathroom, toilet wash countertops and furniture of the table. When choosing marble material, but also deal with whether the smooth marble surfaces, edges or without defects, cracks, scratches, or without trachoma, whether pure tone screening and other aspects.

     In short, the quality requirements of marble veneer finish, stone fine, beautiful color, edges and corners neatly, the surface may not have hidden injury, weathering, corrosion and other defects.

     Construction Technology: The marble decorative panels, should be completely clear grassroots ash and debris, rinse with water and dried. Bonding layer must be dry and hard mortar, mortar should mix, mix cooked, do not use lean mortar. SHOP mortar moist grass, cement paste brush evenly, immediately lay mortar bonding layer, the bonding layer of mortar should be tapped rubbed flat. Paving the front panel, the plate should be soaked, dried, after the trial shop, and then formally paved. After positioning the plate even tap compaction, sprinkle dry cement surface paving is strictly prohibited.

     Acceptance should focus on whether the formation of solid marble finishes paving seams straight, no skew, no dirt accumulation and paste marks, clean surface, color coordination. Furthermore, it should pay attention to whether the hollowing plate, whether the level of bias seams.

Ceramic stone plate paste hanging method

Specific steps:
1, primary treatment: For pasting construction, flatness is especially important grassroots, grass-roots should be smooth but not calendered. Its tolerance is: surface roughness deviation ± 2mm, yin and yang angle vertical deviation ± 2mm, facade vertical deviation ± 2mm.

2, according to design drawings, carefully verify the actual size of the grassroots and deviations, and put bombs aspect baseline.

3, according to the size of sub-grid plate put in Wall base plate block elastic line of position, and review verification, to ensure that accurate.

4, to determine the position of the sheet and paste points and do the drilling process. (Pore diameter φ10 ~ φ12mm)

5, remove the adhesive substance is not conducive to the primary surface of the wall, dust and ceramic stone plate on the back of the hole, the mortar, grunge, floating pine, etc., manual removal may be difficult to completely remove the angle grinder. Also make sure the surface is dry grass, firm not loose.

6, after the gel according to the drawings required to gum paste and put it on a predetermined point, wiping glue thickness should be greater than the back plate to the wall grassroots clearance distance 5mm.

7, after the microcrystalline stone wall paste, according to the horizontal leveling with a spirit level correction.

8, after a microcrystalline stone positioned to deal with the adhesive to be checked, if necessary, to add rubber reinforcement.

Introduction of naming natural decorative stone

In the colorful world of stone, how they name it? For a long time, our country and the world stone circles formed several naming convention.
1, place names add color. That stone origin plus color. Such as Indian red, white Carrara (Italy), Laiyang Green, Tianshan blue, red asbestos.
2, the image name. Namely stone colors, patterns characteristic metaphor of nature in the physical image. Such as the magnificent, snow, blue, screw turn, wood, spray, tiger.
3, the image plus color naming. In order to have a physical image of the stone patterns plus color name, such as Ai Ye, amber red, red rosin, Huang Jinyu, green Jinyu, red agate.
4, names (official) plus color name. Plus celebrity or official colors. Such as Guan Yu Red, Royal Red, Imperial red, the generals red, Guandi red.
5, animals and plants add color. In the name of the flora and fauna of the flora and fauna plus color name itself. Such as sesame white, malachite green, red daisy, chrysanthemum white. Of course there are other naming convention.
In addition, exports to the needs and resources of the census, the state also made of stone work uniform numbers, it is the number of China's natural stone with a scientific approach, but the actual work really use standardized number is not much, just in engineering use drawings and international trade in a number of documents.

Use decorative stone there are three errors to be significantly out

There are "building epic" reputation of the stone in a growing number of home or commercial construction decoration is widely used, but not all use are reasonable, the reporter recently from the just-concluded "2004 Shanghai outstanding stone construction 'Stone Award '' contest was informed that at the moment there are three stone using obvious errors.

    One myth is that a number of construction companies and owners of the properties of the material properties of rock and stone applications cooked enough, learned or afraid to use stone, such as exaggerating the problem of radioactive; or carping, such as requiring stone without color; either subjective act on whim, such as hard do use some sandstone walls, but not high maintenance cost and so on. These are to some extent affected the promotion of the use of stone as the main building decoration materials.

    The second misunderstanding is stone works heavy material and light techniques. Some owners and construction workers on the stone color, texture and attention to a plus, but with the color of the stone, the technical content of construction have generally inadequate attention, undue emphasis on the material itself, "Quality is king", a result of poor technique due affecting the decorative effect. For example, materials with discord, flatness, color, corner treatment not very refined, sloppy, even in difficult technical difficulty factor there are still some quality problems large stone hanging construction and so on.

    Misunderstanding number three is only fitting heavy initial investment, ignoring conservation during use. "Three texture, seven conservation" is decorated with stone "iron law", but in practice, people tend to look at the texture of the material, environmental protection and other property, willing to spend money to buy materials, but once the renovation is completed, in the course rarely carefully tended, often they think of it, or will you have time to "tidy up tidy up", lack of regular maintenance. This will greatly affect the appearance of the beautiful stone, endoplasmic excellent continuity.

    Meanwhile, the reporter also learned that the current stone works have reached a considerable level: high altitude such as stone dry hanging and mixed with glass and aluminum curtain wall; make full use of stone interpretation of European and Chinese classical architectural style; artificial stone and stone-products a large number of ground-breaking applications indoors and outdoors, as well as thin stone top indoor applications, 9 cm thick exterior stone pavement, a large medallion with a large area of ​​the same color combination of stone and so on, are reflected in the innovative application of stone, but also Stone applications where trends.

    It is reported that since 2003, Shanghai stone industry held annually outstanding stone construction project "Stone Award" contest. There are 134 projects in 2004 election, involving 45 construction companies, 42 stone business, covering all areas of office, hotel, commercial, residential quarters, bridges, etc., of which 24 projects have been "Magnolia" award. Ultimately, there are 60 projects won "Stone Award" title.

Limestone is characterized by what?

Limestone is a sedimentary marine lagoon, usually gray, black, compact structure aphanitic massive structure, layered, thick-bedded. Main minerals calcite, dolomite minor, also common clay, quartz, feldspar, glauconite, iron oxide, and some biological remains. CaO based chemical ingredients, generally 45% to 55%, such as "Hang ash" marble CaO is 55%; times for MgO, SiO2, Al2O3, but rarely (chemical analysis loss of ignition up to 35% 50%). According to its composition, structure, formation mechanism, contained different impurities can be divided into chemical limestone (limestone that is often referred to), biological limestone, oolitic limestone, clastic limestone.

    Limestone bulk density of about 2.7g / cm3, compressive strength 65 ~ 100MPa, blistering cold dilute hydrochloric acid, Mohs hardness of 3.5 to 5. Porosity of 0.53% ~ 13.36%, 0.09% to 0.7% of water absorption, the degree of saturation of 0.25%, 0.35 coefficient of saturated water, limestone with a certain color, which is a good decorative stone. Such as Hangzhou, "Hang ash", Anhui Lingbi "red Lo Wan", Hubei Huangshi "pink lotus" and marble are limestone products.

Stone surface texture

Today there are many types of landscaping stone, the stone in order after processing of some type. The following cases of the six major types of stone surfaces:

    1. Grinding
Surface smooth, slightly shiny, you can choose a different gloss. The surface is very smooth, but porous. In many places the People's Bank of this surface is very common. Because the ground floor large aperture, you should always use penetration sealant. Grinding stone polishing surface bright color is better.

    2. Polishing
Shiny surface, over a period of time will be too many pedestrians and conservation due to improper and lose their luster. Such a surface smooth and less porous. After polishing reflective crystals produce brilliant colors, showing the natural stone mineral particles, the gloss is from the natural reflection stone tile crystals. The formation of the polished surface, not glossy coating produced using tiles and polishing powder in production.

    3. Fire
Rough surface is formed at high temperatures. When production of the stone is heated, crystal burst, thus rough surface. Porous surface, must permeate the sealant. http://www.stonegroupon.com/

    4. Roll
Surface a little rough, through the marble, granite, limestone and sometimes tumbling debris in the container, into old look. Often need to use stone toner makes the color more vivid.

    5. Sandblasting
Sand and water with high-pressure jet sprayed onto the sand stone, formed glossy, but not a smooth surface.

    6. ax
By hammering, the formation of surface texture, choose roughness.

Universality of radioactivity present in nature

Radiation phenomena on Earth earlier than the birth of mankind, that mankind is in radioactive environment phenomena multiply dozens of years. Almost all substances containing radioactive elements on earth, including our humanity itself. From natural stone, containing radioactive substances is yes, normal.

      Stone radioactivity level with other building materials radioactivity levels roughly equal

      Build our survival, residential, office space, almost all building materials, raw materials for producing building materials taken from nature, radioactivity level of the stone is a low-dose radiation ore, can not and will never be fast (short-term) lead to deterministic effects ʱ?? That is because some newspapers reported the laying of "cuckoo green" granite XXX caused infertility, or because stone radioactive lead to the occurrence of various types of cancer. This argument is based on a lack of theory and practice.

      To what extent stone radioactive effects on human health

      Low doses of radiation, professionals have different views, both sides lack the necessary clinical data stream sick science survey. But one thing is health hazard deterministic effects, and for building materials, stone production of low-dose radiation, cancer may occur, the probability of occurrence of cancer increases with increasing dose, usually a few hundred thousandths. This risk is not than by car, train ride high risk, construction, mining street inheritance. Stone standard classification is not harmful or harmless dividing line, it needs to be done and the cost benefit analysis, that a particular practice when human benefits greater than the price paid, then such practice is justified.

A stone bond strength and stain resistance of ways to improve

Natural stone such as granite, marble due to the decorative and weather resistance, widely used in interior and exterior of the building, floor, etc. Construction of natural stone paving method commonly used cement mortar. But with cement mortar paving stone not only easy to pollution, and because of its bond strength fluctuations, unstable, causing the stone to fall off. To solve this technical problem, now stone bond strength and stain resistance method according to foreign literature Introduction to an improvement.

An improved method of
In natural stone surface and the side that is modified with a functional group mortar contact surface is coated with a composition containing reactive acrylated. This not only prevents pollution stone mortar, but also to improve the bond strength of stone and mortar.

Second, the test
Take three natural granite conduct bond strength and stain resistance test: a group of natural granite face and the side of Table 1 coated to a coating weight of modified acrylic acid, dried for 24 hours, another group of natural granite in stone surface side is coated with a sealant, dried for 24 hours; in another group of natural granite without any treatment. Test methods are as follows:

1, adhesive strength test
Evaluation of a planar tensile strength test.

2, stain resistance test
(1) resistance to weathering. Immersed in a 10% solution of sodium coast;
(2) resistant cement etching: Immersion in water and cement (2:10) dubbed the cement slurry;
(3) Resistance to red ink pollution: in red ink solution (10-fold dilution) in.

Basalt is characterized by what?

The chemical composition of basalt and gabbro similar, SiO2 content varied from between 45% ~ 52%, K2O + Na2O content than intrusive rocks slightly, CaO, Fe2O3 + FeO, MgO content is slightly lower than the intrusive rocks. Mineral composition is mainly composed of mafic composition of feldspar and pyroxene, secondary minerals are olivine, amphibole and biotite, rocks are dark, usually black, sometimes grayish green and dark purple. It was patchy structure. Stomatal structure and almond universal structure.

   Basalt bulk density of 2.8 ~ 3.3g / cm3, dense by compressing great strength, up to 300MPa, and sometimes higher, the strength decreased in the presence of vitreous and pores. Basalt durability is very high, joints and more possessed brittleness, thus easily mined large pieces of stone, as pores and almonds common structure, although widespread basalt on the surface, but can be used for facing stones much.

Granite, marble radioactive material

Situation granite, marble and other building materials containing radioactive substances disclosed, immediately aroused fear in many people. "Decorated room with natural stone is not equal to suicide you?" In response to this view, the State Building Materials Industry Bureau stone expert quality monitoring center that: talk stone mere mention is unscientific, is completely unnecessary. ʱ??

      Experts pointed out: radioactivity everywhere, our planet itself is a radioactive source rock, the presence of radioactive soil is a natural objective laws. That thrive in human beings have a certain background values ​​of natural radioactivity in the environment. If human beings do not live in a little radioactive environment, the body's immune function may have been destroyed or reduced.

      Stone decoration materials in class, A class of decoration materials sales and use of unlimited scope. Class B is not available for the interior surface decoration materials including residential, apartments for the elderly, nurseries, schools, hospitals and other civil construction, including Class I, but it can be used both inside and outside finishes I kind of external finishes and other civil buildings ʱ?? Class C decoration materials can only be used for external finishes of the building. ʱ??

      At present, China is a Class A granite decoration materials more than 95%. Therefore, consumers can rest assured that the purchase and use of marble, granite products.

Artificial stone finishes

Artificial stone known as synthetic stone, artificial marble and artificial granite in general. The development of modern industrial technology, promote the development of the construction industry, building decoration materials production technology innovation, so that the production of lightweight, high strength, beautiful, multi-species, more economical building materials as possible, artificial decorative stone is in this situation Under arise. Its colors, patterns can be produced according to the design intent, a lightweight, high strength, acid and alkali, anti-pollution, light construction and so on. Compared with natural stone, synthetic stone is a more economical decorative materials, without losing the texture and texture of natural stone, can be widely used in building indoor and outdoor decoration.

      Artificial stone in a foreign country for several decades. In 1958 the United States that is using a variety of resins as binders, added more fillers and pigments to produce a simulation of natural marble texture plates. By the late 1960s and early 1970s, artificial marble Russia, Italy, Germany, Spain, Britain and Japan, the former has developed rapidly, a lot of artificial marble instead of part of the natural marble, granite, widely used in shopping malls, hotels, exhibition halls, airports and other places of the building walls, countertops and furniture cylinders and facades. In addition to the production of decorative plates, States also produce a variety of special products, and even manufacturing sanitary ware. By the late 1970s, the United States has more than half of new residential use of artificial marble, has a well-known international brand WLSONART, ARBORITE United States and Europe RESOPAL Wilsonart International Ltd. is by far the world's largest production and sales of various types of decorative panels of multinational companies. Federal Republic of Germany Adem Company (ADM) is a polyester concrete manufacturing equipment earlier artificial marble company in the world. Brighton Italian company (Breton) in the early 1960s began producing plate molding equipment, vacuum forming equipment and large pieces of artificial marble and marketing world.

      Artificial stone production process is simple, not complicated equipment, a wide range of raw materials, affordable, and therefore many developing countries have begun producing artificial marble. China in the late 1970s, beginning from abroad artificial stone samples, technical information and equipment, 80 years into the development period, the current quality of some products has reached international level of similar products, successfully applied to renovation works in high places

Granite will fade it?

The problem is consumers often mentioned, but in terms relative to the marble, granite can say "never fade." But in the long run, granite will fade, but it is time.

     Granite mineral is mainly composed of feldspar, quartz, mica, pyroxene, hornblende and other components. Some silicate minerals in the main structure, each silicon ions are surrounded by four oxygen ions, while constituting silicon-oxygen tetrahedron. This basic structural unit, nature is quite stable, acid and alkali can be strong, insoluble, resistant to weathering, no discoloration good.

     Granite stone fade because of different varieties also have differences. Generally speaking, the more dark colored granite easily fade, because dark color (such as black, dark green) is mainly composed of granite mineral pyroxene, hornblende, magnetite and other basic plagioclase. Light-colored granite mainly acidic plagioclase, K-feldspar, biotite, quartz. Minerals are generally formed in the ground, some minerals formed first, after some form. First form is often heavier atomic weight of the elements, the position of deeper, less oxygen supply, greater pressure; after the formation of the opposite. Therefore, different minerals generally have different formative years, which is roughly the order: dark minerals: olivine - pyroxene - hornblende - biotite; light-colored minerals: mafic plagioclase - acidic plagioclase - K-feldspar Stone - Quartz. After the formation of the first exposure to the mineral surface, greatly due to environmental changes, easy to produce secondary changes, the change is less formation of late, the most stable quartz. Another case is of secondary minerals than the primary minerals easy to fade, such as epidote, chlorite become the main green, grass green decorative plates, after 5--10 years, the color is fading, but with marble phase ratio, this change is still very weak. Color change (fade) also related to the environment, a high acid content in the industrial zone in the air, then easily change fade. Also maintenance level is also important.

Stone Selection Policy

Currently, the major use of stone as decoration purposes, compared with other decoration materials, the biggest difference is that the Department of Natural stone minerals, in many ways, such as various aspects of color, texture, and construction materials, etc. have made it unique Therefore, also in the selection of its application Road; conditions. Overall, the choice of stone to be considered from the following aspects:

  First, the budget cost considerations

Stone is a natural mineral-based, different stone because of its quality, quantity, mining land .... so different, often there will be a significant difference in price, and therefore, when the owners and designers at the beginning of the selection, they should have cost a considerable degree of control.

  Two expression, aesthetics

Other stone color, pattern and texture factor in the selection belongs to the more subjective level, often due to the owners and designers preferences vary, but if natural stone more in-depth understanding of the expression of artistic conception will be designed in even more remarkable flexible.

Classification ore formed mainly igneous, sedimentary and metamorphic rocks are three commonly used local construction marble stone main places category (metamorphic rocks) and granite class (igneous) based; in general, marble stone with more class rich in color and pattern, texture performance on a smooth and gentle-based, and granite class although less variation in color and pattern, but there are more flexible in terms of the texture of performance (see Table 2-1). In addition, the granite appears to be more solemn and classical in the overall feeling.

      Third, the stone quality control

      1. Material uniformity and integrity:
We should try to avoid cracking and other dark, black scar and color problem.

      2. Stone Ingredients:
(1) Avoid excessive inner stone contains iron sulfide, iron oxide, salt, carbonaceous clay .... and other harmful substances.
(2) Avoid stone containing radiation ingredients.
(3) Avoid stone containing mineral components within the high coefficient of thermal expansion, thermal and electrical conductivity, in order to avoid the risk of cracking, thermal and conductive.

Stone surface contamination and against

First, pollution and erosion of the stone surface

      People choose decorative landscaping stone, the main reason is for beauty, but now almost all of the country due to previous installation used directly without surface treatment, a long time, due to the stone itself reason or process from outside influence or cause the formation of stains, rust, discoloration, peeling and other drawbacks common, even ubiquitous. This greatly affects the appearance, which should be valued lower. Therefore, decorative stone installation before construction or during use of the surface treatment is extremely important. Foreign decades ago to carry out research in this area, and have devised various methods of surface treatment, while China is just in its infancy, it is necessary to strengthen work in this field. http://www.stonegroupon.com/

      Second, several common symptoms and causes of pollution violations

      stone tile saw cutting through the sand into a rough board, face flushing with water if not clean, more or less stick with iron, longer storage time, the wool board surface rust. Air of carbon dioxide, sulfurous acid gas dissolved in the rain, will corrode the marble stone to lose their luster.

      Because the stone has a fine pore water to penetrate, so that anchor rusting steel, iron leaking, causing rust. Wet paste installation, sheet metal and concrete in contact with water leaking alkaline solution stone surface, after drying, often forming a basic crystalline substance attached to the surface of the stone, the so-called anti-base phenomena (Bai Hua), commonly known as " drip nose "," tears ", the stone pollution discoloration. For the kitchen, the bathroom, stairs, handrails, etc. due to exposure to various oils or dirt to form traces of oil or stain. Stone products due to improper packing straw, damp or wet was, could easily lead to spots, especially by sea erosion during transport, easier to form discoloration. Stone wool characteristics and the evaporation rate is a key factor in the stone straw erosion rate. At higher temperatures or stone surface in direct sunlight, eroded faster, accelerating its surface discoloration. Because the stone pores, cracks must have access to water, causing ice cracking, cold and heat changes in the temperature difference between day and night can also cause the stone to crack. Stone encounter moisture qualitative distribution of soluble salts, in particular will be subject to abuse, so the beach stone, because the salt solution dry, wet wind erosion change, make it easier for the stone discoloration. Corrosion. Organic growth, such as moss, fungi, algae color, lichens, etc., so that the stone surface form a variety of spots, the city some organic matter in order to survive, had to sulfide, nitrogen oxide and carbon dioxide in the air as protest, and will change the texture of the stone.

Granite will fade it?

The problem is consumers often mentioned, but in terms relative to the marble, granite can say "never fade." But in the long run, granite will fade, but it is time.

   Granite mineral is mainly composed of feldspar, quartz, mica, pyroxene, hornblende and other components. Some silicate minerals in the main structure, each silicon ions are surrounded by four oxygen ions, while constituting silicon-oxygen tetrahedron. This basic structural unit, nature is quite stable, acid and alkali can be strong, insoluble, resistant to weathering, no discoloration good.

   Granite stone fade because of different varieties also differ. Generally speaking, the more dark colored granite easily fade, because dark color (such as black, dark green) is mainly composed of granite mineral pyroxene, hornblende, basic plagioclase, magnetite Wait. Light-colored granite mainly acidic plagioclase, K-feldspar, biotite, quartz. Minerals are generally formed in the ground, some minerals formed first, after some form. First form is often heavier atomic weight of the elements, the position of deeper, less oxygen supply, greater pressure; after the formation of the opposite. Therefore, different minerals generally have different formative years, which is roughly the order: dark minerals: olivine - pyroxene - hornblende - biotite; light-colored minerals: mafic plagioclase - acidic plagioclase - K-feldspar Stone - Quartz. After the formation of the first exposure to the mineral surface, greatly due to environmental changes, easy to produce secondary changes, the change is less formation of late, the most stable quartz. Another case is of secondary minerals than the primary minerals easy to fade, such as epidote, chlorite main ingredient is green, grass green decorative plates, after 5 to 10 years, the color is fading, but with marble phase ratio, this change is still very weak. Color change (fade) also related to the environment, a high acid content in the industrial zone in the air, then easily change fade. Also maintenance level is also important.

Stone vomiting yellow phenomenon clearance and prevention

Who spit stone for stone industry yellow, rust and straw printing phenomenon should be fully understood, since most people relatively weak notion of stone conservation and other well-known reasons, tend to wait until there is a problem project uses "Which pain doctors Which "approach to remedy, why we do not take" preventive measures "approach to eliminate the problem happen?

      First, we should understand the reasons for the stone vomiting yellow and rust phenomenon.
      1. Stone higher raw material iron content (such as the American white linen), carbon dioxide and water in the air invade the stone surface, iron and stone interior of the reaction generates two iron, and discharged through the stone pores to form the macula.
      2. Sawn stone in the process of surface residual iron, such as by water washing is not clean, long-term storage and the formation of rust.
      3. Rust caused by rusty anchor bars.
      4. Stone finished using rope tied packaging, water or moisture, long-term storage or long-distance transportation, easily lead to stone discoloration.
      5. Hang wet stone installation, cement mortar during the curing process, through the pores of the stone mortar pigment discharge stone surface, forming a stain, especially light-colored or white stone (such as jazz white, Aston white, beige Spain) most prone this phenomenon.

      Clear vomiting yellow stone above phenomena can be divided into physical removal and chemical purge two kinds.

      Physical removal: polishing abrasive wear off the macula. However, this method is more suitable for the flat stone is not yet installed, for stone or shaped stone installed little meaning, and material and labor costs.

      Chemical clear: we all know, the main ingredient is a mixture of rust iron hydroxide and iron hydroxide II. Materials and methods so as long as the correct use of chemical purge is the most convenient and economical. Traditional chemical cleaning agents there are two, that is, from hydrochloric acid, corrosion inhibitors, mist Yang preparations, hydrochloric acid and oxalic acid rust remover Rust (saturated solution of oxalic acid prepared) activation agent formulated. These two advantages are clean, low cost, but if not promptly treated water for washing or flushing is not complete, often counterproductive, untreated non-yellowing, treated the place but "relapse", serious damage to the stone It glosses.

      Stone descaling agent currently on the market of imported and domestic brands of many, because our research and development work in this area started late products, product quality and effect to be further improved and enhanced. Here we have the German company AKEMI stone rust agents and related products, for example, put some of my experiences and usage raised for discussion with you.

      AKEMI Rust Remover is a free hydrochloric acid scavenger, which is mainly composed of a nonionic primary surfactant and preservatives, of which the surfactant contains corresponding biodegradable detergents, can penetrate the stone surface hydroxide iron and iron hydroxide and the two converted into other substances, rather than as we imagine the rust wash. It spit yellow American white linen effect was particularly evident, but again excellent products also have the right to use, we after nearly four years of application, has accumulated some experience.

      Stone factory use: the rust remover evenly coated in a clean dry stone large plate finishes and four sides, then two stone finishes stand face stickers (this can save a veneer of rust dosage), When the paste approximately 10-12 pieces of slate, with polyethylene film in advance to pave the way for the slate covered and sealed with adhesive tape holding 12-24 hours, then water thoroughly washed finishes and four sides.

Chinese stone culture Summary

China, as one of the world's four ancient civilizations, five thousand years of culture, profound, springs from a long.

  China's stone art originated very early, from the towering spectacular Great Wall of Wei and Jin Dynasties era to cut the Dunhuang Grottoes, from Sun Yat-sen in Nanjing Ming Tombs magnificent architecture, from the Forbidden City, the Summer Palace, the Great Hall of the Royal Building, Shanghai Bund buildings, from the palace to the temple carved stone art ...... Chinese folk culture and colorful stone, the stone became indispensable part of Chinese life. In religion, architecture, gardens, cemetery, is unique.

  Dating back million years ago, ancient petroglyphs; Western Han Huo headstone sculptures; world-famous "Dunhuang, Yungang and Longmen Grottoes" and other places of stone statues; Tang, Song tomb stone; Chinese calendar of the imperial camp Court building and capital Tiananmen Square Chinese table and lions, which are all the motherland treasure, history is also a microcosm of the development of national culture.

  Our ancestors, long ago, it began to be applied to the decorative arts of the stone. Han Dynasty stone portraits of rich content recorded the prevailing social reality, ancient mythology, astronomy images. Each historical era dug caves, both reflected the various sectors of society to the extent of religious identity and architecture development process, but also to the stonework who provide a vast world, so they created numerous exquisite stone work seat ʱ?? These are part of traditional Chinese culture, it should be engraved in the hearts of those who want to stone the art of Chinese people.

  Stone broaden the application, and promote development of the industry.

  Stone as a building material, is currently in the indoor and outdoor decorative art, urban sculpture, landscape engineering, road transportation, chemical light industry raw materials, precision instruments and machinery parts, small crafts and other aspects has been applied. In terms of the stone material utilization, but also there is a great potential.

  Stone industry is a long history of industry, which originated from China's stone resources and the rich variety of species, according to preliminary proven national reserves of 30-50 one hundred million cubic meters of marble; granite reserves of over 100 billion cubic meters, and widely distributed. After years of development, mine construction stone, machinery and abrasive manufacturing, production and operation of enterprises across the country, employing nearly 400 people. Progress and economic development of the exchange of information, technology, and further broaden the horizons of people, so that technical equipment and processing stone industry has been continuously updated. In the era of reform, opportunities and challenges coexist in the broad market, how to promote the development of the industry, it is the subject of our co-workers in the stone.

  Stone is the earliest human history of the development of building materials. Stone for its natural beauty, decorated with people's indoor and outdoor environments, the ancient and modern architectural history and write a magnificent chapter in stone and gorgeous masterpiece, a unique stone culture, become the world's brilliant culture an important part.

  China is the world's ancient civilizations, the Chinese people in the long history of development, creating a number of stone buildings masterpiece, recorded the glorious history of the Chinese stone culture. Stone application design in modern buildings, the optimization of production structure of stone, has an important reference value and collection value.

  Chinese granite, rich marble resources, deposit spread throughout the provinces, municipalities and autonomous regions for the development of the stone industry, has laid a very favorable basis. With the continuous development of people's living standards, it requires a lot of excellent performance of various architectural decoration materials. Because of its unique natural stone decorative effect, in architectural culture, representing more and more important role, so will the stone products made more demand, prompting stone industry toward a more extensive development of the market.
