Home decoration stone with the use of quartz stone more and more, the most common is the cabinet table, although the quartz stone is born with high-temperature resistance, if the quality of the quartz stone table is not good, there will be local discoloration and cracking.
Quartz stone plate is composed of more than 90% of natural quartz and about 10% of the color, resin, and other adjustments of bonding, and curing additives.
Artificial quartz stone after negative pressure vacuum, high-frequency vibration molding, and then heating curing, its hard texture, compact structure.
It has the advantages of wear resistance (Mohs hardness of 6-7 or above), pressure resistance (density 2.0g/ cubic centimeter), high-temperature resistance (temperature resistance of 300℃), corrosion resistance, permeability resistance, and so on. And does not contain pollution sources or radiation sources, is a kind of green environmental protection artificial stone.
In this many people will wonder since the quartz stone can withstand temperatures up to 300°, why the hot container directly on the table will cause rupture and discoloration?
As aforementioned, quartz stone material contains 10% of the resin solvent, in high temperature after easy to appear thermal expansion and contraction phenomenon, due to local suddenly heated such as table installation not reserved expansion joint is easy to crack or container bottom mark discoloration. whoever uses quartz stone countertops at home should avoid direct contact with hot containers and recommend the use of heat insulation pads.
