Thin stone refers to stone plates with a thickness of 10 mm~15 mm. It is an important product of the stone industry in the 1990s, which can be divided into marble sheet and granite sheet; Ultra thin stone refers to all kinds of stone plates with stone thickness less than 10mm. Generally, the thickness of granite plate can only be 8mm~10mm, and the specification is 305mm * 305mm. However, people with lofty ideals in the stone industry have devoted themselves to research and practice for many years. Now they can make the marble plate as thin as 2mm, and the maximum size can be 1200mm * 2400mm (the thickness increases with the size). The thickness of granite plate can be as thin as 3mm, and the maximum size can be 1200mm * 1200mm, making it the thinnest marble and granite stone tile at present.
The biggest advantages of thin and ultra-thin natural stone materials are small size, light weight, natural design and color, uniform water absorption, solid and durable, convenient for transportation, colorful, can be made into the specifications of ordinary tiles, and has a wide range of uses. Ordinary adhesive (dry powder paste) can be fixed on the wall, which is a fashionable building material.
At present, thin and ultra-thin natural stone materials are commonly used in China, including 305mm * 305mm, 600mm * 400mm, 1600mm * 600mm, 600mm * 900mm, 800mm * 800mm, 1050mm * 1050mm, 1200mm * 1200mm, 1200mm * 2400mm and other specifications. The thickness varies from 2mm to 10mm, which can basically meet various needs according to user needs.
The weight of thin and ultra-thin products is light, which is only one third of that of ordinary plates. Some data show that the weight of 6mm thick ultra-thin plates is less than 18kg per square meter, and the weight of 8mm thick ultra-thin stone is less than 25kg. In terms of design, the consumption of steel and concrete can be reduced in the overall structure of the building, and the overall material cost of the building can be greatly reduced; In terms of construction: the installation is convenient and the cost is less. The special adhesive pasting method (dry powder pasting) can be used for pasting stones, while the ordinary plates are installed by the cement mortar pasting method or the steel dragon backbone hanging method. Compared with the two methods, the special adhesive pasting method is more convenient to purchase, less in use, and easier to operate than the cement mortar, and can be completed easily by people, which not only reduces the cost of raw materials for buildings, And save more than 60% of the working hours for decoration and decoration. At the same time, the special glue for stone has good water retention and isolation, so as to better avoid the pollution caused by cement efflorescence on the stone decoration and decorative surface and the occurrence of water spots, white tiles and other phenomena.
Thin and ultra-thin natural stone materials reduce the cost because of their "thinness". With their excellent characteristics of thin, light and transparent, they are generally considered as one of the most ideal green building materials in the 21st century. It can not only reduce the cost of stone decoration, but also save and effectively use the limited precious stone resources. In addition to direct pasting, it can also be made into honeycomb panels, composite panels, etc. If a building originally used 30000 square meters of natural stone, the weight will be reduced by at least 1800 tons after using ultra-thin stone, and the unit construction cost will be reduced by more than 100 yuan; And it has been proved by the use of ultra-thin boards in foreign buildings that ultra-thin natural stone can better withstand earthquakes, thermal expansion and cold contraction and other harsh environments.
