The ultra-thin natural stone board is recognized as a green building material for the 21st century due to its light weight, light pattern, natural pattern and durability. Natural stone ultra-thin board is widely used in the production of honeycomb composite panels, aluminum-plastic composite panels and direct paste decoration. Its distinctive features are:
1. Green and environmental protection, saving resources. In today's society that advocates green environmental awareness and advocates the protection and rational use of the earth's mineral resources, stone, as a limited mineral resource on the earth, is receiving more and more attention from governments and people of all countries, saving stone mineral resources, especially It is rare, odd, special stone ultra-thin natural stone slab production and use is undoubtedly in line with the above requirements and development trends, not only can save and effectively use China's precious stone resources and imported precious stone, and ultra-thin plates are radioactive Low, uniform water absorption, corrosion resistance, weather resistance, solid and durable, natural color and anti-fouling and easy to clean.
2. Light weight and convenient construction. The ultra-thin natural stone weighs only one-third of the weight of ordinary plates. From the design aspect, the amount of concrete and steel used can be reduced from the overall structure of the building, which greatly reduces the construction cost. From the construction point of view, the product In the installation, the composite board is used for dry hanging or the special glue for stone is used to paste and dry the cement mortar with ordinary board. It has the advantages of less glue, easy operation and convenient purchase, and can be completed by one person or a few. It can reduce the production cost of raw materials, and can save more than 70% of the construction time, especially the direct paste. The special glue has good water retention and isolation, and better solves the pollution problem caused by the pan-alkali of the stone finish. Therefore, the appearance of stone water spots and white glaze caused by the sticking of cement mortar is also avoided.
3. High strength and good impact resistance. The natural stone ultra-thin board is made of honeycomb board and aluminum-plastic composite board. The compressive strength of the product is 3-5 times that of ordinary board, and it has the characteristics of high flatness, strong shock resistance, fireproof, sound insulation and heat insulation effect.
4, good gloss, such as Jinan, Jinan, Shandong, can reach more than 100 degrees. With good light transmission, the natural stone's natural and beautiful texture can be fully displayed with the light effect, giving the living space a simple and natural, elegant and warm, noble and timeless and long-lasting artistic conception. It can be applied to the ground, floor, ceiling and interior and exterior walls. The decorative construction is an ideal decorative material for offices, homes and entertainment venues.
5. The world has been widely used, and China has yet to be widely promoted. Ultra-thin natural stone has been mass-produced in the United States, Italy, France and Germany, and is widely used in various buildings. For example, a building using ultra-thin stone in Alaska, USA, after years of harsh environment and suffering from more than one major earthquake, is still safe to use without any abnormality; France's new Arc de Triomphe uses honeycomb panels, Shanghai gold The Mao Building uses German ultra-thin plates. In the United States and other countries [the number of manufacturers of the family has an annual output value of more than 1 billion US dollars, due to high prices, the Chinese market has not been able to do so, so it has not yet advanced to the Chinese market. With the advancement of the Beijing Olympics and the Shanghai World Expo, the application of ultra-thin panels in construction will gradually be promoted and used in Chinese buildings. Currently, several companies in Changzhou, Dalian, Xiamen and Shandong are in China. The production of ultra-thin natural stone plates and composite boards has good benefits. In China, the price of ultra-thin composite panels is as high as US$300 per square meter, and Shanghai Jinmao Tower is nearly 4,000 yuan per square meter when it is decorated with ultra-thin stone composite panels (including installation fees). According to relevant information, there have been 26 years of history of stone honeycomb panels for exterior wall decoration in foreign countries.
6. China has a low price and a large profit margin. The low price is an important feature of Chinese stone products compared with similar foreign products. It is not only reflected in the low labor force in China, but also the price of stone blocks is lower, and the price of ordinary plates is lower. However, after the ordinary plate is cut, the added cost is only: the fixed thickness is about 10 yuan per square meter, the polishing fee is about 5 yuan per square meter (the other side is polished), and the cutting cost is 5 square meters. Yuan, a total of about 20 yuan per square meter, sold to a composite board factory or builder about 900 yuan per square meter. It can be seen that the processing value of ultra-thin board is higher, the profit margin is larger, the market is attractive, and the prospect is good.
