In the kitchen decoration, quartz stone is a very good choice for the selection of the table material of the cabinet, and many families are sure to choose quartz as a table. But some people found that the quartz stone table has been used for a period of time, there will be cracking and fracture, especially in the season of alternately spring and summer is the high season of quartz stone mesa cracking, is it because the quality of the purchased quartz stone is not good? Today we will know why quartz quartzite is easy to crack and fracture.


First of all, we need to understand the characteristics of quartz products. Quartzite is a brittle polymer composite material, with a certain thermal expansion and shrinkage characteristics, as well as some mechanical properties such as a certain shrinkage stress, impact toughness, fracture elongation 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.
Because of the different location of cracking, the reasons for cracking are also different.
1, the cause of the cracking of the mesa at the stitching seam: the joint joint is not aligned, the glue coating is not uniform or the curing agent is added to the glue and the accelerator overdose is added to the glue during the installation.
2, the cause of the corner cracking: if the wall is too tight and the contraction joint is not reserved, or the level of the two closet is uneven or the adjustment level, the crack is caused by the external force impact or the uneven contraction of the temperature.
3, the reason for cracking on the mesa opening is that the unreserved gap between the opening and the basin and the hearth is caused by the uneven shrinkage of the mesa due to the temperature change. The way of opening is right angle opening or open grinding without external force.
4, the reason for the cracking of the mesa center is caused by high temperature and external force, the uneven level of the cabinet, or the internal damage caused by the plate.
Although quartz stone countertops are occasionally cracked and cracked, quartz stone countertops are still the first. Each product has its weakness, can not be "perfect product".
