After decades of the rapid development of quartz stone in our country, the proportion of quartz stone used in home decoration is increasing, especially the use of cabinet countertops is the most common in home decoration. As a result, exposed problems have become more and more obvious. For example, explosion and partial discoloration have become the biggest problems bothering quartz stone manufacturers and industry professionals.

Quartz stone plate is composed of more than 90% natural quartz, 7% resin, and other additives for adjusting bonding, coloring materials, curing agents, etc. Artificial quartz stone is formed by negative pressure vacuum, high-frequency vibration, heating and curing, its texture is hard, and its structure is compact. It has abrasion resistance (Mohs hardness above 6-7) and pressure resistance (density 2.3g) unmatched by other decorative materials. /Cubic centimeter), high-temperature resistance (temperature resistance of 300 ℃), corrosion resistance, anti-permeation does not contain any pollution sources and radiation sources, green artificial stone.

Many people here are wondering why quartz stone can withstand temperatures up to 300°, why the hot container directly on the table will cause explosion and discoloration? Because of the 7% resin solvent in the raw material of the quartz stone slab mentioned above, it is prone to thermal expansion and contraction when exposed to high temperatures. Due to sudden local heating, such as when the expansion joint is not reserved during the installation of the table, it is easy to crack or mark the bottom of the container. Discoloration.

In fact, this is also the physical property of quartz stone. 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 stress, impact toughness, and elongation at break. When the material cannot withstand the internal stress caused by thermal expansion and contraction And cracking occurs when subjected to severe external impact.
