Choosing a cabinet countertops for kitchen decoration is an important part. The quality of countertops will directly affect the service life of cabinets. The countertop is in direct contact with food, so the environmental performance requirements are relatively high, and its wear resistance, scratch resistance, and easy cleaning performance must be considered. Among the many countertop materials, quartz stone is worth our choice, but the price of quartz stone is also relatively high. The price of well-known domestic brands should be more than 500 yuan per linear meter.
Among many artificial stones, quartz stone is a combination of natural beauty and high technology. The hardness of the quartz stone plate can reach Mohs hardness level 7, which brings a lot of inconvenience to processing. If seamless splicing is to be done, the technical requirements of the processing master are relatively strict. Many quartz stones tend to be deformed, warped, or broken within half a year or a year after installation. What causes this?
In fact, this series of problems are not caused by the sheet itself, because quartz stone is a brittle polymer composite material, which also has the characteristics of thermal expansion and contraction, and also has certain mechanical properties such as shrinkage stress, impact toughness, and elongation at break. Performance. When the material cannot withstand the internal stress caused by thermal expansion and contraction and is subject to severe external impact, it will deform, splicing seam cracks or plate breakage, which is directly related to the installation of the table. Therefore, sufficient expansion joints should be reserved when installing the countertop, and a gap between the countertop and the wall should be 3-5mm. The countertop pads should be arranged reasonably to avoid deformation and uplift of the plate due to uneven stress on the countertop.
