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.

　　The choice of fireproof materials is very important in the building. Because fire is a destructive disaster, fire-proof materials in buildings can slow the spread of the fire and buy time for rescue. It can also lower the combustion temperature, red

　　With the increasingly serious noise pollution in cities, more and more people are using sound-absorbing panels to improve their quality of life. There are many kinds of sound-absorbing board materials.

　　The water absorption of thermal insulation material is an important index, because the thermal insulation material with poor water absorption performance will greatly affect the thermal insulation effect. If the thermal insulation material is easy

　　Aluminum foil coated glass wool board is a common insulation material, which is mainly composed of glass wool inside and aluminum foil outside. I will analyze it from the following aspects:　　1. Thermal insulation performance: the thermal conduct
