In many artificial stone products, quartz stone plate is a new type of stone made of 93% quartz sand powder as the main aggregate, 7% resin, pigment and other auxiliary materials as the main adhesive material. After mixing, it is made by vacuum compression molding, curing and polishing. Because of the large density and high hardness of the plate, the quartz stone has excellent anti scraping and anti fouling property. It is not floral, impermeable, stain resistant, corrosion resistant, high temperature resistant, green and green, and can be directly contacted with food. So it is called quartz stone by quartzite manufacturers in artificial stone products. However, the physical properties of quartz stone have fine thermal expansion and contraction, there are some mechanical properties, such as certain shrinkage stress, impact toughness and so on. When the material can not bear the internal stress caused by thermal expansion and contraction, and the crack will occur when the external impact is serious.

Therefore, in order to ensure the quality of quartzite finished products, we need to pay attention to the following points in processing and installation.
1. In the design of plane splicing, the physical properties of quartz should be taken into account to avoid the consequences of the joint cracking due to thermal expansion or contraction or stress concentration. The force action of the plate must be taken into full consideration when selecting the connection position. Avoid connection at the corner or the mouth of the furnace.
2. When designing table corner, stress concentration should be taken into full consideration, causing cracking at the corner of the table. Therefore, the arc angle of more than 25mm should be maintained at all corners.
3. When opening the opening position, the opening position should be greater than or equal to 80mm from the edge of the table, so as to prevent the hole from cracking. The corner of the opening should maintain the fillet of more than 25mm radius.
4, when the table is installed, there should be 3-5mm expansion gap between the table and the wall, so as to effectively ensure the table surface is not cracked due to thermal expansion and cold contraction.
