How to purchase the right quartz stone for polishing quartz countertop
Quartzite is an artificial stone made from broken glass and quartz sand. The biggest advantage is wear resistance, no scratch, heat resistance and no deformation. The table made of quartz stone plate has higher toughness, stronger anti external crack force and longer service life. Let's take a look at its buying skills.
1. Check wear resistance by knife stroke
The quartz stone mesa is mainly composed of silica, with the highest hardness. The quartz stone on the market is synthesized by quartz crystal and resin, and the content of quartz is about 93%. Therefore, the possibility of fracture is very small, and it is also wearable. The pseudo quartz has high resin content and low surface hardness, so it is easy to scratch. The purchase, can use the knife on the table and try to make sure.
2. Soak test with hydrochloric acid
In order to maximize profits, some manufacturers will be doped with calcium carbonate on quartz quartzite raw materials. Calcium carbonate and easily reacts with the acid, if you buy the table, later used, it is easy to change the table. Therefore, when buying, you can take a sample plate and put it in dilute hydrochloric acid or other acid liquid. If the product contains calcium carbonate, it will react with the acid.
3. Test infiltration
The surface and internal structure of high quality quartz stone plate are also meticulous and uniform, so the water absorption rate is low, and the permeability resistance is strong, but the backward production equipment and technology are often limited to the appearance, but the internal structure is loose and porous, the anti permeability is weak, the water absorbability and impermeability are strong. When buying, you can pour soy sauce on quartz stone table to check whether it will color. The inferior quartz stone surface will color for 1 days, but the high quality will not.
4, High temperature test
Quartz stone, because of its own material characteristics, determines its high temperature resistance, the temperature below 300 degrees Celsius will not have any effect on it, that is, no deformation and fracture, poor quality of quartz stone resin content is too high, heat resistance will also be reduced. Therefore, we can use this point to burn samples with lighters and see if there are any traces on them.
5. Compare the density
Good quality quartz stone has higher density and heavier weight. So the same size quartz stone will be heavier.
