The most important thing to buy quartz stone is to look at the finish because the finish represents whether it will absorb the color. Quartz stone is very troublesome to absorb the color. If you get a little oil, you can’t get it off. I will teach you a method. Buy a marker on the quartz. Scratch on the stone to see if it can be wiped off. If you wipe it off, the color will not be absorbed. If you can’t wipe it off, don’t buy it. The quartz stone produced by a regular manufacturer has a code on the back. Pay attention to the sign. Hardness is the identification of wear resistance. The simple method is to use a steel knife to draw, and the key cannot be used for identification. Take the “white crystal” as an example. A steel knife traverses it, leaving a white mark on the fake quartz stone. Because the plate is not as hard as steel, the surface is cut by the steel knife, revealing the white inside. While the pure quartz stone is scratched by a steel knife, it will only leave a black mark, which is caused by the steel knife not being able to scratch the quartz stone, but leaving traces of steel, one black and one white, the true and the false appearance.
Quartz stone is made of 94% quartz and 6% resin, with a hardness of 7 degrees, while granite is synthesized from marble powder and resin, so the hardness is generally 4-6 degrees. Simply put, the ratio of quartz stone The granite is hard, scratch-resistant, and wear-resistant.
Quartz stone is resistant to high temperatures due to its own material characteristics. The temperature below 300 degrees Celsius will not have any effect on it, that is, it will not deform and break; because of its high content of resin, granite will be exposed to high temperatures. It is particularly prone to deformation and scorching. Quartz stone is a non-radiation product and has no adverse effects on the body; the raw material of quartz stone is non-radiation quartz, and the granite is made of natural marble powder, so there may be radiation, which may cause adverse effects on the body.
When looking at the sample, there is a protective film on the surface of the stone. Quartz stone surface does not require any processing. Quartz stone countertops are currently the first choice for cabinet countertops. High-quality countertops generally use 100% high-quality all-aluminum powder. The consumption of white vinegar can make all inferior artificial stones and quartz stones show their original shape. (Other types of vinegar are invalid, such as aged vinegar is invalid). Pour a tablespoon of white vinegar on the artificial stone and quartz-stone countertops. After 30 seconds, if a reaction occurs: for example, many tiny bubbles are generated, the “granite” in the fake quartz stone and the artificial table “calcium carbonate” and white vinegar All can react and produce bubbles. Such countertops are low in price, easy to age, and crack, absorb color and have a short service life. If the price per linear meter is less than 700 yuan, you have to consider whether it is a stone countertop.
