Ceramic Fiber Cotton

Ceramic fiber cotton is a loose fiber made by melting the raw materials at high temperature in a resistance furnace and forming fibers by blowing or spinning without secondary processing and heat treatment. It is used in fields such as fiber blankets and board product raw materials, high-temperature kilns, heating devices, wall lining gap filling materials, wet process product raw materials, fiber spraying, castables, coating material raw materials, corners and complex space insulation filling materials, etc.

1,High temperature tolerance
Ceramic fiber cotton are extremely resistant to high temperatures. The operating temperature of ceramic fiber paper can usually reach above 1000C and can withstand various strengths and stresses at high temperatures.
2,Corrosion resistance
Ceramic fiber is chemically stable and is not corroded by most acids, alkalis and solvents, and has strong corrosion resistance.
3,Low thermal conductivity
Not only can ceramic fibers withstand high temperatures, they also have very low thermal conductivity. Even at high temperatures, ceramic fibers will not transfer heat quickly and will not affect the temperature of the surrounding environment.
4,durable
Ceramic fiber is a very hard and wear-resistant material, which has strong wear resistance and reduces the wear of mechanical parts.

5,Lightweight
Since ceramic fiber is very light in mass, in some environments that require lightweighting,it can be used to replace other materials to achieve lightweight purposes.

Ceramic fiber cotton are divided into two categories according to their composition: glassy (amorphous) fibers and polycrystalline (crystalline) fibers.

1) Glass fiber production method

The production method of glassy ceramic fiber is to melt the raw materials in a resistance furnace. The high-temperature melt flows out from the discharge port and flows to the high-speed spinning roller of the multi-roller centrifuge. The centrifugal force of the spinning roller spins the high-temperature melt into Fibrous material. The high-temperature melt can also be quenched by the force of high-speed airflow and blown into fibrous materials.

2) Polycrystalline fiber production method

There are two production methods for polycrystalline ceramic fibers cotton : colloid method and precursor method:

Colloidal method: soluble aluminum salts, silicon salts, etc. are made into a colloidal solution of a certain viscosity, which is formed into fibers by compressed air injection or centrifugal disk spinning, and then converted into aluminum-silicon oxide crystal fibers by high-temperature heat treatment.

Precursor method: Make soluble aluminum salts and silicon salts into a colloidal solution of a certain viscosity, use puffed organic fibers to evenly absorb the colloidal solution, and then perform heat treatment to transform it into aluminum-silicon oxide crystal fibers.

Ceramic fiber cotton fit in High temperature environment filling sealing and insulation (kiln cars, pipes, kiln doors, etc.), fiber composite materials (such as friction discs, etc.), various industrial furnace linings (hot surface and backing), building fire protection, sound absorption, high temperature filter materials , raw materials for thermal insulation and refractory fiber products for deep processing.
