Ceramic fiber paper is suitable for insulation, insulation, sealing, edge protection, sound absorption, filtering, etc. in higher temperature environments. The raw material for manufacturing ceramic fiber paper is Aluminium silicate ceramic fiber loose cotton. The production process is generally as follows: breaking loose cotton and then producing lightweight insulating refractory materials through wet forming process.
Ceramic fiber paper is widely used for high-temperature insulation of various industrial furnaces, steel ladles, and submerged nozzles; As well as the electrical edge and insulation materials of industrial electric furnace, the sealing materials of furnace door and furnace Expansion joint, in addition, they can also be used as the thermal insulation materials of higher temperature instruments and equipment; It can also be used for glass demolding during the peeling of microcrystalline glass and hot melt glass. It can not only serve as the inner wall of the lining as insulation material and sealing material for high-temperature appliances, but also as a good insulation material for low-temperature refrigeration equipment in refrigerators.
Ceramic fiber paper is made of ceramic fibers, so ceramic fiber paper itself does not contain asbestos and can replace commercially available asbestos products. Ceramic fiber paper has long raw material fibers, high strength, low bulk density, and fixed elasticity. Therefore, it is convenient for construction operations such as punching, winding, and cutting. It is precisely because ceramic fiber paper undergoes manufacturing processes such as high-temperature firing that it has good resistance to high temperatures, thermal shock, chemical corrosion, low thermal conductivity, high edge strength, and high elastic modulus.
Good ceramic fiber paper has the following advantages:
1. High strength tear resistance
2. Higher flexibility
3. Low slag content
4. Difficult to layer
5. Low thermal conductivity
6. Thermal shock resistance
