Q:What are the best companies (including imported products) in China?

This kind of material has the characteristics of not rotting, not burning, high temperature and so on For example: asbestos, diatomaceous earth, perlite, glass fiber, foam glass concrete, calcium silicate and so on Pu cold under the cold material used organic insulation materials, such materials have a very small thermal conductivity, low temperature, flammable and so on For example: polystyrene foam, polyvinyl chloride foam, polyurethane foam, cork and so on According to the shape can be divided into porous insulation tears orbital material, fibrous adiabatic tears orbital material, powder insulation and layered insulation materials four Porous insulation material, also known as foam insulation material, with a light weight, good insulation properties, good elasticity, dimensional stability, poor stability and so on Mainly foam, foam glass, foam rubber, calcium silicate, light refractories and so on Fibrous insulating material can be divided into organic fiber, inorganic fiber, metal fiber and composite fiber In the industry for the insulation of the orbital material is mainly inorganic fibers, the most widely used fiber is asbestos, rock wool, glass wool, aluminum silicate ceramic fiber, crystalline alumina fiber 窢 ridge to promote But the debt and so on Powder insulation materials are mainly diatomaceous earth, expanded perlite and its products These materials are rich in raw materials, cheap, is the construction and thermal equipment on the application of a wide range of highly efficient insulation materials
