Characteristics of quartz and quartz stone have this feature reason quartz made from selected natural mineral quartz crystals in an amount of more than 99.9% SiO2 Dongguan quartz, and in the manufacturing process to the complex purification, the raw material does not contain any possible leading to heavy metal impurities radiation, 94% of quartz crystals and other resin additives makes no radiation pollution quartz quartz quartz Why research? 1, fire board table: Facing for the fire board. Thickness: 4mm, colorful and diverse, fire quartz structure, moisture quartz stone, resistant to oil, acid and alkali, high temperature quartz Kai Sa, easy to clean. However, compression, scratch resistance, hardness can not meet the requirements, and life is short. So fire board table has become increasingly unable to meet the demand for human consumption, the market share of 30% from the beginning to 5% or less.
