First, the polycrystalline mullite fiber cotton products:

Polycrystalline Mo mullite fiber (PMF), cy polycrystalline alumina fiber is in home and abroad at present the new super light-weight refractory fibre is the Al2O3-SiO2 ceramic fiber in two different products, use temperature of 1500 to 1700 degrees, higher than the glass fiber in form of 200 to 400 degrees. Can be widely used in metallurgy, machinery, electronics, ceramics, chemical industry, aerospace and other high temperature industrial furnace and other thermal equipment lining insulation. In order to achieve energy saving, prolong the service life and improve the working environment. Appearance is white, smooth, soft, elastic, especially for cotton.  

Second, polycrystalline mullite fiber cotton products:

Polycrystalline Mo mullite fiber is a kind of unique to Mo to mullite crystal phase that forms in the presence of amorphous refractory fiber and complicated manufacturing process, high scientific and technological content, in a foreign country only a few developed countries can produce this product, such as silicon carbide company in the United States, Britain's ICI (ICI) Company and Japan, Germany and several companies. Polycrystalline Mo mullite fiber peacekeeping glass state fiber with different preparation process, it is by chemical colloid method for preparing, is by the formation of the single crystal mullite (Al2O3, SiO2) for chemical formula and chemical composition is Al2O3 72%, SiO2 28% of the. The principle is that the soluble aluminum, silicon is made with a certain viscosity colloidal solution, using conventional methods of liquid thrown silk, after high temperature heat treatment complete crystal phase transition, of mullite fiber. Of the cotton fiber (bulk) as filling material of high temperature parts of sandwich, the loose cotton by wet vacuum forming of PMF fiber series varieties, such as board, carpet, brick, standard ISO prefabricated pieces, module, combination of components, such as.  

Polycrystalline alumina fiber is a crystal fiber in the form of corundum phase, it also uses the chemical "colloidal method" to make, the manufacturing process is more complex,

The chemical composition is: Al2O395%, SiO25%. The prepared fiber cotton (bulk) can be made into a plate, a brick and a standard different prefabricated component by the wet method of vacuum forming.

Third, polycrystalline mullite fiber cotton application:

As the base material, can be used as the raw material of fiber deep processed products such as plate, paper and special shaped parts.

Packing material for expansion joint or short heat insulation repair.

Fiber reinforced materials for thermal insulation concrete and bond.

Fourth, polycrystalline mullite fibers commonly used specifications Mo cotton products:
