Ceramic fiber production line
Ceramic fiber is an aluminosilicate based refractory fiber, with light weight and very low thermal conductivity. They provide excellent insulation at high temperature, and resist corrosive chemicals such as commonly used acids and alkalis. It is ideal for refractory applications.
Classification of ceramic fiber products
- Kilin insulation
- Blanket
- Board
- Paper
- Rope
- Bulk
- Textile
- Moulded products
Application of ceramic fiber products
- High temperature furnace
- Lings
- Stress relieving
- Gasket application
- Fireprotection
- Acoustical insulation
- Sealings
- Expansion joints
- Heat shields
- Other refractory application
Manufacturing process
The fiberization process begins with a mix of alumina and high purity silica which is melted at 1926℃. A molten stream of this composition is then sheared which attenuates the material into fibers. A binder is then added and the mixture is formed and cured in the curing oven. The preformed fiber then undergoes cooling and sawing process to achieve the final high quality product. Further treatment of the fiber product could also be conducted.
