What’s the high temperature resistance of quartz slab?

The proportion of quartz stone in decorative stones is increasing, especially the use of cabinet countertops is the most common in family decoration, and the problems of leakage are more obvious, such as cracking and local discoloration.quartz slab

Quartz slab is composed of over 93% natural quartz and about 7% color, resin and other additives for adjusting bonding and curing. Artificial quartz stone is formed by vacuum and high frequency vibration under negative pressure. It is solidified by heating, its texture is hard and its structure is compact. It has the incomparable wear resistance (Mohs hardness grade 6 or more), pressure resistance (density 2.0g/cubic centimeter), high temperature resistance (temperature resistance 300 C), corrosion resistance and permeability resistance without any pollution and radiation source. It belongs to a new green environmental protection artificial stone material. Quartz stone is also more expensive than other stones.

Speaking of this, many people will wonder why the thermal container directly placed on the table will cause explosion and discoloration, since the quartz stone plate can withstand high temperature up to <300 degrees. Because the quartz slab material mentioned above contains 7% resin solvent, it is easy to appear hot expansion and cold contraction phenomenon after high temperature. If there is no expansion joint reserved during construction, cracks or stain discoloration at the bottom of the container will easily occur due to sudden local heating. Quartz quartz manufacturer advises users to avoid direct contact with heat containers and use heat insulation pads.
