Artificial quartz stone is from more than 90% natural quartz and about 10% of the colorant, resin, and other regulatory bonding, curing additives. Is the result of negative vacuum, high-frequency vibration molding, heat curing (high and low temperature curing agent is a sheet according to the type of production process and can not be processed from its hard texture (Mohs hardness 5-7), dense structure (density 2.5g / cm3) has other decorative materials can not match the wear and pressure, high temperature, corrosion-resistant, anti-penetration properties.
