The proportion of quartz in home decoration stone is getting higher and higher, especially the use of cabinet countertops is the most common in home decoration, and the problems exposed are more obvious, such as bursting and partial discoloration. Today, ABC QUARTZ explained the reasons for the explosion and discoloration of quartz stone countertops.

Quartz stone countertop green

Quartz stone countertops are made up of more than 90% natural quartz and about 10% colorant, resin and other additives to adjust adhesion, curing and so on. The artificial quartz stone is formed by vacuum vacuum, high-frequency vibration molding, heating and solidification, its texture is hard, the structure is compact, and it is incomparable with other decorative materials (Mohs hardness 6-7 or above) and pressure resistance (density 2.0g). / cubic centimeter), high temperature resistance (300 ° C temperature resistance), corrosion resistance, penetration resistance does not contain any pollution sources and radiation sources, green and artificial artificial stone.

Avoid direct contact with the heat container

In this case, many people will wonder that quartzite can withstand temperatures up to 300°. Why does the heat container directly on the table cause cracking and discoloration? Because of the above-mentioned quartz stone plate material containing 10% resin solvent, it is high temperature. After the heat is prone to cold shrinkage, due to local sudden heating, such as the expansion of the expansion joints, it is easy to crack or the bottom of the container is discolored. Quartz stone manufacturers suggest that users should avoid using thermal insulation mats when the hot containers are in direct contact with the countertops.
