In this many people will wonder since quartz stone can withstand temperature up to 300, why the hot container directly on the table will cause cracking and discoloration? Because the quartz stone material contains 7% of the resin solvent, in high temperature after easy to appear thermal expansion and contraction phenomenon, due to the local suddenly heated such as table installation not reserved expansion joint,it is easy to crack or container bottom mark discoloration.
Quartz stone in China after decades of rapid development, now quartz stone in home decoration use ratio is higher and higher, especially the use of cabinet mesa in home decoration is the most common.And then the problem of leakage is more and more obvious,such as cracking and local discoloration has become the biggest problem plaguing quartz stone manufacturers and industry personage.
In fact, this is also the physical properties of quartz stone. Quartz stone belongs to the brittle polymer composite material, also has the characteristics of thermal expansion and cold contraction,there is a certain shrinkage stress,impact toughness, elongation at break and other mechanical properties, when the material can not withstand the internal stress brought by thermal expansion and cold contraction and serious external impact will appear cracking.
Quartz stone plate is composed of more than 90% of natural quartz and 7% of the resin and other regulatory bonding, color, curing agent and other additives.Artificial quartz is a negative pressure vacuum and high frequency vibration molding, heat curing, its hard and dense structure has unmatched by other adornment material wear-resisting (mohs hardness level is above6 to 7)and pressure(2.3 g/cm3density), high temperature (300 °C) of heat-resistant, corrosion resistant, anti osmosis does not contain any pollution and radiation source,green environmental protection artificial stone.
