Alumina silicate fiber cotton refers to fibers produced by blowing or spinning methods, which are gathered into loose fibers by a cotton collector or sedimentation device. Also known as raw cotton fibers, it serves as raw material for processing secondary fiber products. It is used as a high-temperature thermal insulation material for various industrial furnaces, steel ladles, casting drums, submerged nozzles, electrical insulation and thermal insulation materials for industrial electric furnaces, sealing materials for furnace doors and body expansion joints, mold interiors for aluminum casting, film removal for microcrystalline glass and molten glass, high-temperature sealing pads, thermal and electrical insulation materials for heating devices of instruments and equipment, noise reduction and thermal insulation materials for automotive exhaust mufflers, and insulation materials for exhaust pipes.

Standard-type alumina silicate fiber cotton is produced from raw material of hard clay clinker, through melting in a resistance furnace and subsequent spinning or drawing process. High-purity and high-alumina alumina silicate fiber cotton is made from high-purity aluminum oxide silica sand material. It is also produced through melting in a resistance furnace, followed by blowing or spinning into fibers.

portant;">Zirconium Fiber CottonThe product is manufactured from high-purity alumina-silicate powder and zirconia fiber, melted in a resistance furnace and then spun or drawn into fibers through blowing or spinning processes.

The adhesive aluminum silicate fiber cotton is made by adding a certain proportion of high-temperature binder during the blowing process of the aforementioned cotton.

2. High-alumina alumosilicate fiber cotton is a fluffy fiber produced by melting a mixture of high-purity alumina and silicon stone powder in an electric furnace and then blowing it.

3. Zirconium-containing aluminum silicate fiber cotton is a fluffy fiber produced by blowing through an electric furnace, using high-purity alumina, silicon stone powder, and zirconia sand as raw materials.

4. Common aluminum silicate fiber cotton is a fluffy fiber produced by blowing, resulting from the melting of hard clay clinker in an electric furnace.
