There are two production methods of artificial stone class, one is pressed plate production, and the other is square material production.
The main raw materials for the production of this tablet are fine particles (such as quartz sand particles, marble ground stone powder, etc.). ) mixing and stirring with chemical adhesive, and then making into plates under vacuum and high pressure; Square production is to break the original stone, add chemical bonding agent, vacuum stir, high-pressure vibration molding, make a few tons of stones, and then cut into building materials slate.
Compared with flat production, square production uses less glue and can use large stones, so the overall cost is lower. There are many pores in the square products, which must be covered with glue, which seriously affects the quality of the products. In addition, the low hardness of its bone material determines that the hardness of this product is very low. Generally speaking, quartz stone produced with quartz sand must be pressed, because quartz sand has a high hardness, and it is extremely difficult to cut if it is produced with square materials.
The use of artificial stone, especially quartz stone, has been quite common abroad, mainly because of the excellent quality of technology, equipment and products, and people's consumption level and environmental awareness are also at a high level. At present, with the continuous development of Shi Gang's industry, Shi Gang is increasingly used in China. According to statistics, in recent years, the annual output of the first generation of Shi Gang in China has reached 30 million square meters. However, due to the high production threshold of quartz stone, there are not many domestic enterprises with production capacity. There are more than a dozen enterprises that use reverse molding technology to produce large-size table quartz stone. Large-sized table quartz stone has a large amount of glue and high hardness, but it is easy to deform when used as a wall material; Only two or three enterprises can produce quartz stone for wall and floor tiles by high-pressure tabletting, and only Murray quartz stone can develop quartz stone with beautiful and gorgeous texture. It is worth noting that some enterprises also refer to the gangshi produced with broken glass quartz stone as gangshi, so we must be careful when choosing it.
Summarize Shi Gang products: the first generation is marble Shi Gang, which is too soft; The second generation is quartz stone, hard but single color; The third generation quartz stone is hard, textured, natural and beautiful, which is the development direction of Shi Gang industry in the future.
