About   Contact    | 

Ceramic fiber blanket is a regular size, and integrates the functions of fire resistance, heat insulation, and heat preservation functions. It does not contain any binder and has excellent chemical stability. It is widely used in fire resistance, heat insulation, and heat preservation in various industries.

Application of ceramic fiber blanket

kiln lining insulation
kiln lining insulation

Ceramic fiber blankets can be used for kiln lining, boiler heat insulation, glass kiln roof heat insulation, flue lining, pipeline heat insulation, electrical heat sealing gasket, heat insulation at welding joints, and heat insulation in nuclear power fields.

Influence of impurities on the properties of ceramic fibers

Some impurities in ceramic fibers, such as Fe₂O₃, Na₂O, K₂O, etc., will react with other components in ceramic fibers at a lower temperature to form eutectics, and the existence of eutectics destroys the network structure of fibers, the viscosity inside the fiber is reduced, the crystallization activation energy required to overcome the rearrangement of ion groups during crystallization is reduced, and the crystallization temperature is reduced.
