Why isolate quartz countertop from heat?

Quartz stone has become the most used stone in decorative stone. Quartz stone is made of 90% quartz crystal and 7% resin and other binders. After vacuum high pressure and high vibration molding, it belongs to artificial stone plate, also known as synthetic stone. Quartz stone has a smooth surface, dense and non-porous, and rich in color, which is comparable to natural stone. At the same time, it has certain advantages such as toughness, non-volatile gas, non-toxic and non-radiative, and large-area use without chromatic aberration.

Quartz stone can be described as the perfect combination of natural beauty and high technology. The sheet is die-casted by pressure above 50 tons. The hardness is not less than 5 grades of Mohs hardness and the density is 2.6g/c m3. Quartz stone has a water absorption rate of only 0.02% and is resistant to penetration. The plate is cured at a high temperature of 150 degrees, so it has a high temperature resistance function, and the quartz stone plate can withstand a high temperature of 300 degrees.

Speaking of quartz stone plate can withstand high temperature of 300 degrees, many people will have their own views, quartz stone manufacturers to show the relevant documents to customers that quartz stone can withstand 300 degrees of high temperature. However, in use, the plates are often cracked after contact with high-temperature objects. Due to the high hardness of the quartz stone plates, it is difficult to repair after bursting, so everyone has doubts about the high temperature resistance of quartz stone.

How many degrees of high temperature can quartz stone plates withstand? I still say more than 300 degrees, because the quartz stone plate is heated to 300 degrees as a whole without any change. Many people will ask why in life, contact with a hot pot will cause a burst! Quartz stone is a brittle polymer composite material with certain thermal expansion and contraction characteristics. When the plate is partially heated, it cannot withstand the internal stress caused by thermal expansion and contraction and will burst. Therefore, the quartz stone plate is heated more than 300 degrees overall, but the local heat will burst due to thermal expansion and contraction.
