Cotton insulation is formed by melting high-purity clay clinker, alumina powder, silica powder, chromium sand and other raw materials in high-temperature industrial furnace, forming fluid. Then use compressed air blowing or spun machine spun into fibers, through the condensor to set cotton, so that cotton insulation is formed.
In the industrial production, usually use molybdenum electrode as a heating element, because molybdenum electrode has good high melting point, corrosion resistance and good thermal and electrical conductivity property. So it is commonly used in the production of cotton insulation in industrial electric furnace. Molybdenum electrode can not only be used in industrial furnace, it can also be applied in glass furnace for melting glass. Molybdenum electrode properties largely affect the quality of products. High density and high purity electrodes, not only conducive to the product, but also help extend the life of the electrode and the furnace.
Cotton insulation is made of high-purity clay clinker, alumina powder, silica powder, chromium sand and other raw materials, forming non-toxic, harmless, non-polluting new insulation material. It is light weight, high strength, oxidation resistance, low thermal conductivity, good flexibility, corrosion resistance, small heat capacity and good sound insulation and other good performance, which can be processed into fiber blanket, board, paper, cloth and rope.
