Artificial granite is a new type of healthy and environmentally friendly stone, is a category in the artificial stone category. So far, the field of granite has developed three generations of products, the first generation of granite bone raw material for marble stone sandstone powder or a small number of granite particles, the second generation of granite bone raw material for quartz sand, the third generation of granite is developed on the basis of the second generation of granite, it is bone raw material is also quartz sand, only to add some advanced equipment and advanced technology so that the finished product has the same as natural marble or even more The finished product has the same or even more elegant and beautiful patterns as natural marble. As the granite has the advantages of non-toxic, low radioactivity, flame retardant, anti-bacterial and anti-mold, impact resistance, rich colors, high-grade luxury, etc., is gradually becoming the new darling of the decoration building materials market, the most potential for development in the stone industry.
There are two ways of producing artificial granite, one is the pressed sheet production, the other is the square material production.
Pressed flake production is the main raw material of fine particles (such as quartz sand particles, with marble grinding into stone powder, etc.) and chemical binder mixed, stirred, in a vacuum state to high pressure made of the plate; square type production is the raw stone broken into the chemical binder in a vacuum state, stirring, and the use of high-pressure vibration to make it shape, made of a block of several tons of rock, and then cut into building materials slabs.
The square type of production is less glue intensive than the pressed type and allows the use of large blocks of stone, resulting in a lower overall cost. The product produced through the square type has more pores which must be covered by the glue, which has a serious impact on the quality of the product. Generally speaking, quartz sand must be used as raw material for the production of quartz stone, because it is very hard and extremely difficult to cut if it is produced in square form.
The use of artificial stone abroad, especially in the use of quartz stone has been quite common, mainly because of the process, equipment, product quality is excellent, people's consumption level and environmental awareness are also at a relatively high level. At present, with the continuous development of the post stone industry, the use of post stone in the country is also increasing day by day, according to statistics, in recent years, the first generation of domestic post stone annual production volume has reached 30 million m2;, but the production of quartz stone due to the high threshold, the domestic production capacity of enterprises with not many, to invert the molding process to produce large-size table top quartz stone enterprises have a dozen, large-size table top quartz stone glue dosage. Although the hardness of the product is relatively high, it is easy to deform when doing wall and floor materials; only two or three companies can produce quartz stone for wall and floor panels with high-pressure pressing, and only one company can develop quartz stone with beautiful and gorgeous texture. It is worth noting that some companies call quartz stone produced from broken glass, in order to confuse them with pearls, so be careful when selecting.
To summarise the post stone products: the first generation is marble post stone, the texture is too soft; the second generation is quartz stone, hard but single color; the third generation of quartz stone, hard and textured, natural and beautiful, is the future direction of development of the post stone industry.
Natural resources are always limited, just as the composite wood flooring to replace the original wood flooring, artificial stone to replace natural stone is also the inevitable trend of social development, and with the social group's environmental awareness and the improvement of the quality of life requirements, artificial stone, especially high-quality quartz stone demand will be more and more. The development prospects of granite are undoubtedly bright, and the development space of quartz stone with personalized is unlimited.
