In decorative stone, quartz stone is a die-cast artificial stone plate, which is made by mixing more than 90% quartz sand powder with 7% resin and other auxiliary materials, and then subjected to vacuum pressure vibration forming, solidification and processing. New stone, also known as reclaimed stone.
Quartz stone plate is natural, superior to natural, and has many advantages such as high density, strong hardness, no scratching, infiltration, stain resistance, corrosion resistance, high temperature resistance, environmental protection, and direct contact with food.
Quartz stone has developed rapidly after entering the decoration market, and quickly occupied the countertop market. As the market demand continues to expand, China's quartz stone industry has developed rapidly. At present, the quartz stone manufacturers engaged in the production in China have more than 1,000 enterprises, and have completed the imitation from the initial follow-up cottage to the independent research and development leading the international market. But the quality of quartz stone is also uneven.
At present, the ratio of quartz stone raw materials is no longer a secret. How can the same ratio show a difference in quality? In fact, there are two reasons: First, the difference in the quality of raw materials, the main aggregate quartz sand powder will be divided into four grades A, B, C, D, etc., the price difference of different grades is also very large. Second, the production equipment, the pressure of the quartz stone plate production press should reach 50 tons or more, the vacuum density should reach -99.8 or more, and the density of the produced plates should reach 2.3g/cm³ or more. Hardness must reach Mohs hardness above 5, which is why it is impossible to scratch the surface with a sharp sharpener. Due to the high density of the sheet, the water absorption of the sheet itself is only 0.02%. In addition, the quartz stone plate should have a certain bending ability, and the bending strength should be greater than 30Mpa, so that the plate has a certain resistance to bursting.
