From a physical point of view, quartz stone sheet is a brittle polymer composite material. It also has the characteristics of thermal expansion and contraction. It also has certain mechanical properties such as shrinkage stress, impact toughness, and elongation at break. When the material cannot withstand heat The internal stress caused by expansion and contraction and cracking will occur when severe external impacts. After all, the quartz stone sheet is an artificial stone product. Let's follow the editor of calacatta quartz slab to understand what are the reasons for the cracking of the quartz stone countertop?
1. The center of the countertop is cracked, etc.: it is subject to high temperature, external force impact, uneven cabinets or pads, internal damage to the board, etc.
2. Cracks in the corners: the wall is too tight and no shrinkage joints are left, the height between the two cabinets is uneven or not leveled, the table surface is not evenly shrunk due to external impact or temperature changes and cracks;

3. Cracks around the above counter basin: there is no gap between the above counter basin and the basin hole, the basin hole is not polished and smooth, and the table surface is cracked due to uneven shrinkage due to external impact or temperature changes;
4. Cracking around the furnace hole: there is no gap between the gas stove and the furnace hole, the furnace hole is not polished and smooth, the table surface is not uniformly shrunk due to external impact or temperature changes and cracks;
5. The rear water barrier is cracked: the cabinet is not level or the backing board is not leveled;
6. Cracks on the connecting surface of the rear water retaining edge: the glue is not firmly bonded;
7. Cracking at the seam of the countertop: When the installation worker is splicing the seam, the seam is not aligned, the glue is not evenly applied, or the curing agent is added to the glue or the excessive amount of the agent is added to make the seam brittle. It will crack when it is slightly impacted during use. .
The above is the introduction of calacatta quartz slab editor: introduction to the causes of cracks on the quartz stone countertop.
