Ceramic fiber is the silicate fiberboard A refractories. Even after heating is maintained good mechanical strength, compared with the product fiber blankets, carpets is rigid and has a support strength of fiber insulation products. Production principle using blown fiber (fiber is short, thin, easily broken mix) as ceramic fiber materials, adding a certain percentage of binders, fillers grade additives, after beater in the slurry pond fully dispersed into the slurry. Pumped to the molding tank and stirred with compressed air. The mold was placed molding pool, using the principle of a vacuum pump, the fiber slurry is adsorbed on the mold. Precise control of the adsorption time, the fiber wet material was vacuum dewatering, stripping, placed in a tray drying oven dried 10-24 hours to give as gifts. After drying fiberboard through a dedicated grinding machine, trimming machine, precise control of dimension. Applications furnace cement and other building materials industry backing insulation; petrochemical, metallurgy, ceramics, glass industry furnace insulation backing; heat treatment furnace insulation backing; non-ferrous metal industry backing insulation; high temperature reaction, heating equipment backing Insulation
