Ceramic fiber is a kind of high-efficiency thermal insulation material, which has the characteristics of light weight, high strength, oxidation resistance, low thermal conductivity, good flexibility, corrosion resistance, small heat capacity and sound insulation. So is the ceramic fiber cotton, which can also be further processed into ceramic fiber blankets, boards, paper, cloth, rope and other products. If you are searching for high quality ceramic fiber products, there is no doubt that RS Company will be your best choice! Email us for more details.
Ceramic fiber cotton is made of high-purity raw materials at high temperature melting using blowing or wire-cast, whose basic features are high temperature performance stability, light weight, low heat capacity and good thermal shock resistance. Meanwhile, it is the basic material of ceramic fiber series products.
The Production Process of Ceramic Fiber Cotton
The whole manufacturing process of ceramic fiber cotton have four steps:
First of all, high-purity clay clinker, alumina powder, silica powder, chrome sand and other raw materials are melted at high temperature in an industrial electric furnace to form a fluid, which is then blown by compressed air or twisted into a fiber by a twisting machine, and next the cotton is gathered by a cotton collector, finally we got ceramic fiber cotton.
Common aluminum silicate fiber cotton is produced by using hard clay clinker as raw material, melting by electric resistance furnace, blowing or twisting into fiber.
High-purity, zirconium-aluminum-type aluminum silicate fiber cotton, using high-purity alumina silica powder as raw material. It is produced by melting in an electric resistance furnace, blowing or twisting into a fiber-forming process.
Excellent Thermal Stability and Chemical Stability
Low Thermal Conductivity
Good Sound Insulation and Mechanical Strength
Good Elasticity
Low Shrinkage at High Temperature
Better resistance to erosion
The Classification of Ceramic Fiber Cotton
Generally speaking, ceramic fiber cotton can be divided into spray-blown ceramic fiber loose cotton and wire-throwing ceramic fiber loose cotton.
Spray-Blown Ceramic Fiber Loose Cotton
There is no binder in spray- blown ceramic fiber loose cotton, and the content of the slag ball is low. The fiber produced by the untreated blown fiber forming process is an excellent raw material for high temperature kiln filling materials and vacuum forming products, fiber spraying and fiber paper.
Wire-Throwing Ceramic Fiber Loose Cotton
The silk fiber is long, the content of the slag ball is low, and the content of non-fibrous material is extremely low in the silk fiber cotton. The long fiber produced by the untreated silk fiber forming process is an excellent filling material for the wall lining of the high temperature kiln heating device, and the excellent spinnability is the raw material of the textile.
Ceramic fiber cotton is the matrial of other ceramic fiber products, such as ceramic fiber paper, ceramic fiber board, ceramic fiber blanket etc. Ceramic fiber cotton can be further divided into five types: common, standard, high purity, high aluminium and zirconium.
The commom ones are made of hard chamotte clayehich are meltdown in resistance furnaces and prodessed by blowing or swinging technology. The high purity and high aluminum ones are made of composite materials of pure alumina and processed by blowing or swinging technology. Zirconium ones are made of composite materials of high purity alumina,silica powder and zircon sands,which are meltdown in resistance furnace and processed by blowing or swinging technology.)
