The most important thing to buy quartz stone is to look at the finish, because the finish represents whether it will absorb color. The quartz stone is very troublesome. If you get a little oil, you can't get rid of it. Teach you a way to buy a marker in quartz. Scratch on the stone to see if it can be wiped off. If it is wiped off, it will not absorb color. If it can't be wiped off, don't buy it. There are also quartz stones behind the regular manufacturers that have coded on the back. Pay attention to the signs. Hardness is also the identification of wear resistance. The simple method is to use a steel knife to draw, and the key can not be used to identify. Take "white crystal" as an example, the steel knife is crossed, leaving the white quartz is a fake quartz stone, because the hardness of the plate is not as good as steel, the surface is cut by a steel knife to reveal the white inside. The pure quartz stone is crossed by a steel knife, leaving only a black mark. The steel knife can't move the quartz stone, but it leaves the trace of steel. It is black and white, and it is true and false. Quartz stone is made of 94% quartz and 6% resin, the hardness reaches 7 degrees, and the granite is synthesized from marble powder and resin, so the hardness is generally 4-6 degrees, which is simply quartz stone ratio. Hard stone is more scratch-resistant and wear-resistant than him. Due to the characteristics of its own material, quartz stone determines its high temperature resistance. The temperature below 300 degrees Celsius will not affect it, that is, it will not deform and break. The granite has a large amount of resin, so it is in high temperature. It is particularly prone to deformation and charring. Quartz stone is a non-radiative product, which has no adverse effects on the body; the raw materials of quartz stone are non-radiative quartz; and the granite is made of natural marble powder, so there may be radiation, which has adverse effects on the body.
When looking at the sample, there is a protective film on the surface of the granite. The surface of the quartz stone does not need any processed quartz stone countertops. It is the first choice for the countertops. The high-quality countertops generally use 100% high-quality aluminum powder. The consumption of white vinegar can make all the inferior quality. Artificial stone / quartz stone /, showing the original shape! (Other types of vinegar is invalid, such as vinegar is invalid). Use a tablespoon of white vinegar to pour on the countertops of artificial stone and quartz stone. After 30 seconds, if there is a reaction: as shown in the above figure, many tiny bubbles are generated, the "stone" in the pseudo quartz stone and the "calcium carbonate" of the artificial platform. White vinegar reacts and produces bubbles. Such countertops are low in price, easy to age, cracked, absorb color, and have a short service life! If the price per meter is less than 700 yuan, you should consider whether it is a granite countertop.
