Quartz stone 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 force, impact toughness, and elongation at break. When the plate cannot withstand the internal stress caused by thermal expansion and contraction Cracking occurs when it is severely impacted.
