Building thermal insulation and sound insulation is to improve the comfort level and energy-saving effect of the building, its basic principle is to close the shell of the building, reduce the transmission of heat and sound.　　The commonly used b

　　External wall insulation is one of the effective means to improve the building thermal environment, meet the requirements of energy saving and enhance the residential comfort. The methods of external wall insulation are mainly as follows:

　　LNG production has become one of the key development projects in various countries. Due to the characteristics of ultra-low temperature (-162℃) storage of LNG, the selection of cooling materials for LNG pipelines has become a problem faced by the

　　Building insulation materials are used to reduce the heat transfer and energy consumption of buildings. They are usually installed on the walls, roofs, and floors of buildings. Common building insulation materials include polystyrene board,

　　It's OK. Rockwool is an excellent insulation material, but also a recyclable material. Waste rock wool can be recycled and reprocessed into new rock wool products, which can not only reduce the amount of waste generated, but also save raw materi

　　Glass cotton roll felt is a kind of thermal insulation material made of inorganic glass fiber as the main raw material, after high temperature melting and forming, and processed by special technology. It belongs to inorganic substances,

　　Rubber and plastic insulation material is a kind of closed cell structure, no water absorption, no water seepage, can effectively prevent water penetration into the material, so as to avoid the building damp, mold, rot and other phenomena.

　　Do a good job of thermal insulation in the freezer, the temperature reaches the storage conditions of the items, in order to achieve the ideal refrigeration effect, refrigerated items will not be damaged.

　　When we are building a house, in addition to the interior decoration of the building, the insulation of the external walls is also very important. Only qualified external wall insulation system, the house can be warm in winter and cool in summer

　　In buildings, ventilation ducts need to have certain fire resistance, because in case of fire, if ventilation ducts do not have fire protection, it will cause the spread and expansion of the fire.
