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.

Stone decoration selection rule

With natural stone patterns and beautiful colors for interior designers to provide a broad creative element in home decoration more and more people want to use some of the local natural stone to increase Austere flavor. Compared to other building materials, stone from the selection, paving the late maintenance, are very particular about, if not heeded, the stone can not show their beauty.

Look surface quality stone factory

It depends on the merits of natural stone blocks of quality and processing. Quality stone surface, without too much noise, cloth color uniform, not suddenly light suddenly strong case, but there are many unable indemnity cover of "defects" quality time after stone processed,stone for building so that the stone surface tone pattern is to evaluate the merits of the important indicators of the quality of the stone. If the processing technology and technology, however, finished products will appear after warping, dents, stains, stain, missing edge off angle, crack, color line, pit nest and other phenomena, such as the stone of course not really "top grade" ʱ??

According to people dedicated to selling imported stone introduction, high-quality natural stone, sheet metal cutting edges should be neat and no chipping, smooth surface, high brightness, no rough sense of touch.

Floor decoration avoid "incredibly hard"

Home decoration using stone, not around the house made "incredibly hard", should choose those light-colored stone as the surface decoration materials, give people a warm, peaceful feeling, but also the effect of the expansion of floor space. http://www.stonegroupon.com/

From the species, should try to choose those resistant, acid and alkali class marble and granite stone class. From the price point of view, production of light-colored granite series of relatively inexpensive, suitable for general income families to purchase, replace the damaged part Hao ingredients. From the specifications sheet, the ground should try to choose granite sheet metal (8-12 mm), which is mainly on account of strength and houses bearing ground two factors.

Decoration Stones

Today, when people decorated room, the pursuit of high-end decorative materials has become a new fashion. In many materials, the use of stone is more common. However, the current quality stone products on the market is good and bad. Most consumers of the type and properties of the stone are not well understood, a well on the gullible.

     Experts told reporters that the common market, the main stone marble, granite, terrazzo, synthetic stone four, where they turned white marble for the top grade marble; granite hard than marble; terrazzo are cement, concrete and other materials from forging; Synthetic stone is a natural stone gravel for raw materials, coupled with adhesives and other pressurized, polishing together.

     landscaping stone is good or bad, "Look out"

     It depends on the merits of natural stone blocks of quality and processing. Experts told reporters that, in general, uniform fine material stone structure has a delicate texture, are superior product; and stone and coarse grain structure ranging from its poor appearance, mechanical properties are not uniform, the quality of the somewhat less. Therefore, the tone pattern stone surface is to evaluate the merits of the important indicators of the quality of the stone.

     In addition, stone tile often due to geological processes in which produce some veinlets, micro-cracks, the stone most prone to rupture along these areas, attention should be removed. As for the lack of edge angle is less aesthetic impact, particular attention should be selected. If processing technology and technology, however, finished products will appear after warping, dents, stains, stain, missing edge off angle, crack, color line, pit nest other phenomena, such as stone, of course not really "top grade ʱ?? So experts say high-quality natural stone, sheet metal cutting edges should be neat no chipping, smooth surface, high brightness, no rough sense of touch.

     Ground stone for building light color

     From the perspective of the home improvement, designers recommend consumers choose home improvement stone, to select those light-colored stone as a floor decoration materials, give people a warm, peaceful feeling, but also to expand floor space effect.

     From the species, we should try to select those resistant, acid and alkali class marble and granite stone class. From the price point of view, production of light-colored granite series of relatively inexpensive, suitable for general income families to purchase, replace the damaged part of the Ye ingredients. From the specifications sheet, the ground should try to choose granite sheets (8-12 mm), which is mainly on account of the ground of strength and houses bearing two factors.

     Color table to dirt

     Stone decorative items into the home, except for the ground more is made of various types of furniture tops, it is necessary to take into account the pollution problems, and thus to choose the color of some of the deep stone, like green, blue, red series of marble Granite can be, those varieties of marble, decorated with a large pattern effect will be better.

     For the kitchen worktop in stone, 25 mm thick plate should be selected, preferably using granite. Because granite in the kitchen too much acid, alkali environment, energy and durable, yet glorious, and there is a very high intensity.
