Classification of thermal insulation materials

Date2016-8-23 16:17:15

There are many kinds of heat insulation material, which can be classified by material, temperature, shape and structure.
According to material can be divided into three kinds of organic heat insulation materials, inorganic heat insulation materials and metal insulation materials.
Heat preservation materials for heating equipment and piping are mostly inorganic heat insulation materials. This kind of material has the characteristics of non - decay, non - burning, high temperature and so on. For example: such as calcium, diatomite, perlite, asbestos, glass fiber, foam glass, silicate concrete.
Under the cold, the heat preservation material is used in the organic heat insulation material, such material has the very small thermal conductivity, low temperature, flammable and so on. For example: polystyrene foam, polyvinyl chloride foam, polyurethane foam, cork, etc..
According to the shape and can be divided into multi hole shape of the adiabatic tears of the orbital material, fibrous insulation tears of the orbital material, powder type insulation and layered insulation material four. Porous insulation material is also called foam insulation material, with the characteristics of low quality, good thermal insulation, good elasticity, stable size, stability, and so on. Mainly foam, foam glass, foam rubber, calcium silicate, light refractory materials, etc.. Fibrous insulation materials can be divided into organic fiber, inorganic fiber, metal fiber, composite fiber and so on. Adiabatic tears Yingkuang materials used in industry is the main inorganic fibers. At present, the most widely fiber asbestos, rock wool, glass wool, aluminum silicate ceramic fibre, amorphous alumina fiber. Powder insulation materials are mainly diatomite, perlite and its products. These materials are rich in raw materials and cheap in price, which is widely used in building and thermal equipment.
