Information

　　Quartz stone is a new type of stone made of 92% quartz sand powder and 8% resin, pigments and other auxiliary materials under high pressure under vacuum and shaped under high temperature. It is an environmentally friendly and green new building material that is free of radioactive pollution and can be reused. And decorative materials.

　　1. Resin content (including all liquid auxiliary materials) 7-12%.

　　Less than 7% has insufficient toughness and is easy to fracture; higher than 12% is easy to deform. Some quartz stones have a resin content of about 15%, so they are fake quartz stones.

　　2. It must be formed under high pressure under vacuum.

　　Whether it is low-pressure forming or casting, the compactness of the quartz stone plate is insufficient, and it is easy to bleed and is not stain resistant, so it is a fake quartz stone.

　　3. The hardness of the quartz stone plate must be provided by quartz sand.

　　Glass is not quartz, and the proportion (mass percentage) of glass particles in the quartz stone plate must be less than 20%.

　　4. Curing and setting at high temperature.

　　Some quartz stones are mainly cold-solidified or low-temperature solidification under 100℃, so they are pseudo-quartz stones.

　　1. Resin: Resin is the matrix material of quartz stone, which has the function of bonding and providing toughness.

　　2. Filling material: The main component of the quartz stone filling material is silica, and the others include: quartz stone sand, quartz stone powder, casting sand, broken glass, shells, sea sand.

　　3. Pigment: The role of pigment in quartz stone is to adjust the variety of colors and colors to make them rich and colorful.

　　4. Curing agent: Curing agent is an indispensable auxiliary for the production of quartz stone, and good quartz stone is cured at high temperature.

　　5. Other additives: The resin is a polymer material. Appropriate addition of some additives can improve the process, increase production efficiency, enhance the performance of quartz stone, and extend the life.
