More and more people choose stone as a decorative material in home decoration, quartz slab because the stone is elegant in shape, the stone decoration is new in the century, the stone has a natural texture, and each piece has vitality. With the pursuit of green life, more and more people choose quartz stone. In particular, the use of countertops is the most common in home decoration, with more obvious exposure problems, such as deformation and cracking. Today, for you to explain the quartz stone table deformation and cracking reasons.
Artificial quartz stone plate is divided into cast plate and die-cast plate, both of which are composed of 93% quartz sand and about 7% of pigments, resins and other adjusting adhesives and curing agents. engineered stone benchtops The cast plate is naturally cured like ordinary artificial stone production, while the die-cast plate is cured by negative pressure vacuum, high-frequency vibration and heating. Its texture is hard, dense structure, with unparalleled wear resistance (Mohs hardness above 6-7), pressure resistance (density 2.0g/u002F cm3), high temperature resistance (temperature resistance 300℃), corrosion resistance and penetration resistance, does not contain any pollution sources and radiation sources. Is a kind of environmental protection artificial stone.
The price of casting quartz stone is relatively cheap, and the quality is also very different from the die-cast plate, and the density, hardness, and permeability resistance can not meet the requirements. Due to the soft texture of the cast sheet, it is easy to deform after encountering high temperatures. Still, many people wonder why quartz, which can withstand 300 degrees of heat, cracks when placed directly on a countertop. engineered stone supplier Because the above quartz stone plate contains 7% of the resin solvent, there will be thermal expansion and contraction phenomenon after high temperature, because there is no expansion joint such as sudden heating of the countertop installation, it is easy to crack. Users should avoid direct contact with the surface of the hot container and should use a thermal insulation pad.
