Is low-priced quartz stone necessarily inferior?
Among the many countertop materials, the processing of quartz stone countertops has very high technical requirements for the processing masters. Due to the different grades of raw materials, the price of quartz stones fluctuates very much, from as low as 300 yuan per meter to as high as a few. Every thousand meters per thousand meters, the brand quartz stone countertops at least 500 yuan a stretch of rice. In general, the quartz stones on the market are domestically and imported, and can be divided into cast plates and die-cast plates from the production process. The price of die-casting board is higher than that of casted board. The imported quartz stone is more expensive, up to several thousand yuan and one meter. Due to different filling materials and production processes, quartz stone sheet is also divided into three or six, etc. Purchase must be recognized.
It is worth noting that 180 yuan per square meter or more than 200 meters per square meter must be artificial granite or cast quartz stone plate. Cast quartz stone and artificial granite are very similar to die-cast quartz stone. However, its hardness and reverse osmosis are very poor, and the stone is not environmentally friendly and toxic. The difference in the price of quartz stone is mainly related to the environmental performance and the size of the die-casting machine, as well as the level of quartz sand used for filling. The price of quartz sand ranges from 800 yuan per ton to 2,000 yuan per ton.
How to distinguish them? In fact, it is very well resolved. Quartz stone has the characteristics of high temperature resistance. Generally, the temperature below 300 degrees will not affect the surface of quartz stone, and there will be no cracks and other conditions (such as the local temperature of the sheet, it should be paid more attention, after all, quartz Stone plates have the characteristics of thermal expansion and contraction). The granite and the casting plate are different. The granite is made of natural marble powder. The common point of the casting plate and the granite is that it contains a large amount of resin components, so it is particularly prone to deformation or zooming in a high temperature environment. phenomenon. Use a cigarette butt to see if there is any mark, and the discoloration is granite or cast quartz. In addition, the sharp surface is scratched on the surface. Since the cast plate and the granite are not subjected to high vibration and the density is insufficient, white scratches and powder appear. Die-casting boards will only have black scratches and can be wiped off with a rag! Since ancient times, it has been a price, and it should be carefully discerned before purchase to prevent being deceived.
