* Tile and ceramic industries (sealing, lining, etc.)
* Chemical industries (lining, sealing, filter separation, etc.)
* Glass industry (hot repairs of molten bricks)
* Transportation industries (brake pads, sound and thermal insulation of body and exhaust pipe, catalytic converters, etc.)
* Sound insulation
Product Introduction:
Ceramic fiber is a type of artificial fiber made of aluminum silicate, which is formed by melting kaolinite with a high percentage of alumina or more conventional materials including a combination of pure alumina powder and mixed silica.
Alumina and silica mixture is prepared by two methods of blowing in tge melt or centrifugal, after melting in electric resistance furnaces at a temperature of about 1800°C. In the melt blowing method, the fiber length reaches up to 100 mm, and in
the centrifugal method, the fiber length reaches up to 300 mm. The formed fibers are white, glassy or non-crystalline. To prepare fibers with special applications, zirconium oxide, lime, magnesium oxide or other oxides are also added to the furnace charge.
Bulk ceramic fibers, which include a mass of long and refractory ceramic fibers with random direction distribution, can be used as a suitable alternative to asbestos.
