Quartz stone countertop processing and installation pay attention to these aspects, to prevent cracking troubles

- Dec 28, 2018 -

Among many artificial stone products, quartz stone plate is 93% quartz sand powder as the main aggregate, 7% resin, pigment and other auxiliary materials are the main bonding materials. After mixing, it is formed by vacuum compression, curing and polishing. New stone made by other processes. Due to the high density and high hardness of the plate, the quartz stone has excellent scratch and stain resistance, scratching, infiltration, stain resistance, corrosion resistance, high temperature resistance, environmental protection, and direct contact with food. Therefore, it is independent of quartz stone manufacturers in artificial stone products, called quartz stone. However, the physical properties of quartz stone have slight thermal expansion and contraction, and there are certain mechanical properties such as shrinkage stress and impact toughness. When the material cannot withstand the internal stress caused by thermal expansion and contraction and severe external impact, cracking will occur. .

Therefore, in order to ensure the quality of quartz stone products, in the processing and installation, you need to pay attention to the following points.

1. When designing the plane splicing, the physical properties of the quartz stone should be taken into consideration to avoid the consequences of joint cracking caused by thermal expansion and contraction or stress concentration. When selecting the connection position, the force of the plate must be fully considered. Avoid connecting at the corner or the mouth.

2. When designing the corner of the countertop, the stress concentration should be fully considered, causing the crack at the corner of the countertop. Therefore, the arc angle of the radius of 25mm or more should be maintained at all corners during processing.

3. When designing the opening position, the opening position should be greater than or equal to 80mm from the edge of the table to prevent the hole from cracking. The corner of the opening should be rounded at a radius of 25mm or more.

4. When the table top is installed, there should be a 3-5mm expansion and contraction gap between the table top and the wall to effectively ensure that the table top is not cracked due to thermal expansion and contraction.
