Would a cheap quartz plate work?

　　

　　Among the many cabinet countertop materials, the processing and production of quartz stone countertops has very high technical requirements for the processing master, and due to the different grades of raw materials, the price of quartz stone fluctuates greatly, as low as 300 yuan per square meter, as high as several thousand There are yuan per square meter, and the brand quartz stone countertops are at least 500 yuan per square meter. Generally speaking, the quartz stones on the market are divided into domestic and imported, and can be divided into cast slabs and die-cast slabs from the production process. The price of die-casting slabs is higher than that of cast slabs, and imported quartz stones are even more expensive, up to several thousand dollars per square meter. Due to the difference in filling materials and production processes, quartz stone slabs are also divided into grades, so when buying must be recognized. 　　It is worth noting that the 180 yuan per square meter or more than 200 yuan per square meter on the market must be artificial granite or cast quartz stone slabs. Cast quartz stone and artificial granite look very similar to die-cast quartz stone from the outside. But its hardness and reverse osmosis are poor, and it is not environmentally friendly and toxic. The large price difference of quartz stone is mainly related to the environmental protection performance, the size of the die-casting machine, and the grade of quartz sand used as filler (the price of quartz sand also ranges from 800 yuan per ton to 2,000 yuan per ton). 　　How to distinguish them? In fact, it is easy to distinguish. Quartz stone has the characteristics of high temperature resistance. Generally, temperatures below 300 degrees will not affect the surface of quartz stone, and cracks will not occur (if the plate is partially heated, more attention should be paid. After all, quartz Stone plates have the characteristics of thermal expansion and contraction). The granite is different from the cast slab. The granite is filled with natural marble powder. The common point of the cast slab and the granite is that it contains a large amount of resin, so it is particularly easy to deform or zoom in a high temperature environment. Phenomenon. Use a cigarette butt to burn it to see if there is a mark. If there is discoloration, it is a granite or a cast quartz stone. The other is to use a sharp tool to scratch the surface. Since the cast slab and granite have not been subjected to high vibration and high pressure, their density is insufficient, so white scratches and powder will appear. Die-cast boards will only show black scratches and can be wiped off with a rag! Since ancient times, you get what you pay for, so you should carefully identify before buying to prevent being cheated
