Quartz stone has become the most widely used stone in decorative stone. Quartz stone is made of 90% quartz crystal and 7% resin and other binders, and then formed by vacuum, high pressure and high vibration. stone. The surface of quartz stone is smooth, dense and non-porous, and its color is comparable to natural stone. At the same time, it has certain advantages such as toughness, no volatile gas, non-toxic and non-radiation, and large-area use without color difference.
Quartz stone can be described as the perfect combination of natural beauty and high technology. The plate is die-casted by more than 50 tons of pressure, the hardness is not lower than Mohs hardness level 5, and the density is 2.6g / cm³. Quartz stone has a water absorption rate of only 0.02% and is resistant to penetration. The board is cured at a high temperature of 150 degrees, so it has high temperature resistance. The quartz stone board can withstand up to 300 degrees.
Speaking of the quartz stone plate can withstand high temperature of 300 degrees, many people will have their own opinions. The relevant certificates presented by the quartz stone manufacturers to customers indicate that the quartz stone can withstand high temperatures of 300 degrees. However, in use, the plates are often cracked after coming into contact with high-temperature objects. Due to the high hardness of the quartz stone plate, it is difficult to repair after the explosion, so everyone has some doubts about the high temperature resistance of quartz stone.
How many degrees of high temperature can quartz stone plates withstand? I would still say above 300 degrees, because the quartz stone plate as a whole is heated to 300 degrees without any change. Many people will ask why contact with a hot pot in life will cause it to burst! Quartzite is a brittle polymer composite material with certain thermal expansion and contraction characteristics. When the plate is locally heated, the internal stress caused by thermal expansion and contraction will burst. Therefore, the overall heating of the quartz stone plate is above 300 degrees, but local heating will cause cracking due to thermal expansion and contraction.
