As the decoration industry has higher requirements for the performance of decoration materials, some new decoration materials are constantly found and used. It is not difficult to find that if this emerging material can always be popular and in great demand, its emergence will be recognized by the public. Now what I want to introduce to you is a very popular material -- rock slab. It is made of natural stone and inorganic clay by special process, vacuum extrusion molding and automatic closed computer controlled temperature roller kiln firing at 1300 ℃. It is the thinnest (only 3mm) and the largest (3600 × 1200mm). The English of rock slab is "SINTERED STONE", which is translated as "sintered dense stone". However, what is rock slab is still in dispute. There are roughly two definitions of rock slab in the industry: first, some people think that rock slab mainly comes from imported brands, and some enterprises that regard rock slab as a single category and operate independently will clearly distinguish rock slab from ceramic tile; Secondly, some people think that the rock plate is mainly from domestic ceramic enterprises. They think that the rock plate is actually a ceramic plate, or a kind of ceramic plate. Compared with traditional building materials, it is a new type of material. As a bathroom or kitchen countertop and background wall, rock slab has many advantages, such as anti pollution, heat resistance, scratch resistance, durability, UV light resistance, and no need for secondary treatment on the surface. One disadvantage is that the rock slab is different from the stone and other table materials, and it does not have the characteristics of full texture. At present, the patterns of rock slabs are basically printed on the surface.
