How about quartz stone countertops?
Quartz stone physical and chemical properties: no radiation, no toxicity, antibacterial and environmental protection, high density, high strength, high hardness, high brightness, acid and alkali resistance, permeability and high temperature resistance, aging resistance, no deformation, no cracking.
Ingredients: quartz stone quartz stone is a kind of high hardness of environmentally friendly composite materials of quartz, as high as 93% natural quartz (SIO2) as the main component, and 7% unsaturated resin, mineral pigments, additives and antibacterial agent mixture, under vacuum conditions in the quartz crystal, resin and trace paint etc. the material is pressed through the heterogeneous polymerization technology.
Performance identification of quartz stone:1) look: with two different brands of models, in the sun sufficient to compare the naked eye, can compare its brightness, know its good or bad.2): with a sharp tool on the surface of quartz stone, if it is easy to draw the traces can not be wiped out, it shows that the hardness is not enough.3) bubble: soak quartz stone in easy to dye things (such as soy sauce, coffee, nicotine). After a period of time, if quartz is dyed, it shows poor permeability.4) smashing: with a certain weight of objects, quartz stone surface smashed, to see the extent of fragmentation, if the fragmentation is too much, it shows that the compactness and hardness is not enough.5) drop: a certain proportion of strong acid, alkali, drip on the surface of quartz stone, can see whether it has bubbles, if there is, then explain mixed with calcium carbonate. Of course, why should we use strong acid and strong base here, because the general situation with a small amount of calcium carbonate, if acetic acid or weak acid, it is impossible to react.
The difference between quartz stone and hillock stone, marble and artificial stone:1) packing separation:(A) quartz stone fillings are quartz content of up to 99.9%, while the hardness of quartz from its own structure, three-dimensional mesh structure makes it difficult to change, its physical hardness is second only to the natural diamond.(B) the filling of the hillock stone contains quartz, and it also contains calcium powder, so its hardness can not compare with quartz stone.(C) marble is a natural stone. In nature, marble is mainly composed of calcium carbonate. Its hardness is also inferior to quartz stone.(D) artificial stone fillers are calcium powder and aluminium powder, and the structure of calcium and aluminum cannot be compared with that of quartz.
