How to evaluate the quality of granite grinding and polishing

The gloss of the decorative stone is an important standard to evaluate the quality of stone. On the one hand, the size of the gloss depends on the size of the refractive index of various minerals, on the other hand, closely related to the microstructure of the stone surface.

With a granite stone its mineral content is certain, surface is smooth, concave and convex defects was less, glossiness of stones is higher. The microstructure of the stone surface is determined by the quality of grinding and polishing. So, in the purchase of granite flooring, the stone grinding polishing is crucial to distinguish the quality. If you don't have some skills, it is a very difficult task to distinguish the quality of grinding, because in our eyes, all the surface of the stone is bright as a mirror. However actual after grinding and polishing the surface decorative stone no matter what seems light bone, the microscope magnified the microstructure is rough, sometimes even in the presence of larger defects.

Appears to the naked eye is as smooth as a mirror of the granite stone surface, under the reflecting microscope and scanning electron microscope can see the stone surface are left after grinding and polishing in the pits, and striations. These pits and streak some is caused by defects of the mineral itself in the current processing conditions cannot be overcome, some of it is because in the process due to the grindstone thickness grade is not reasonable or grinding polishing is not completely caused.

To observe these very minor defects, we need to be very careful and meticulous, but also to grasp a certain way. We have processed stone surface toward the sun light or fluorescent lamp, observe the reflective surface can be clearly identified as shown in the various pits and streak. For those irregular small pits may is mineral some defects caused by stone composition, can not to consider,tile and if you find some regular streaks on the surface of the stone is caused due to the poor quality in processing, the purchase should try to avoid this kind of stone.

Before installing the stone first good protection precautions

Currently, high-tech where to buy landscaping stones conservation products and technology, building stone for professional treatment, the stone before installation, must be effective protection for stone processing, reducing the chance of a variety of issues that arise late. Because of the characteristics and composition of the stone itself is extremely complex, so when a problem occurs again deal with and often a waste of time and money, but also may not be able to completely solve the problem, manufacturers of the stone caused great loss of goodwill, which is everyone want to see to; for consumers, spent a lot of money and time, but can not be satisfied with the final quality, it is wrong; for architects or designers, careful creation into ointment. So do before construction protective treatment, not only can ensure the quality of construction, future maintenance is simple, no waxing, just vacuumed before, then rag moistened with water and wipe or mop that economical and convenient.
Special protective agent can penetrate the stone house, forming a protective layer, a waterproof, anti-pollution, anti-rust spots, anti-oil, weathering, aging, acid, anti-stain caused by tea stains, cola, soy sauce and other effects and can effectively control the generation of Bai Hua, without prejudice to the permeability of the original types of landscaping stone walls, usually cleaning effect can be achieved by simply wiping with water.
Matters stone protector construction process is to be noted
1, before using repellant, make sure that all surfaces to be treated thoroughly clean and free of any sediment and particles;
2. repellant to brush the surface of the stone is no longer working, but not for the reprocessing of cheap landscaping stone surface. As for re-processing stone, application penetration method, but more waste;
3, stone tree processing, love wash, dry (about 72 hours), brush protectant is better;
4, the construction, to dip the brush to brush more full, the better placed flat stone;
5, after brushing the first pass, and then they go after repellant infiltrated the best brush a second time;
6, the organic silicon products, 24 hours after the brush do waterproof protection;
7, according to the actual situation, determine five or six surface protection and face protection:
8, can not use the two products;
9, carefully read the product manual, and strictly followed.
