Rongsheng ceramic fiberboard, because it is produced by vacuum wet molding, can also be called vacuum-formed refractory fiberboard products. Rongsheng manufacturers can customize the shape and size of ceramic fiberboard according to the actual needs of customers. Vacuum-formed refractory ceramic fiber products are rigid or semi-rigid refractory ceramic fiber products produced by vacuum wet molding with refractory ceramic fiber wool as the main raw material.

The Production Process of Rongsheng Ceramic Fiberboard

During production, according to the different physical and chemical performance requirements of the finished product, appropriate varieties of refractory fibers, adhesive fillers, flocculants, etc. are selected and mixed with water to form a slurry. And adjusted to a certain concentration and pH value. Then injected into a mold with a filter, vacuum dehydration molding, demoulding, and drying. Finally, the finished product is obtained after processing and finishing. Refractory fiber is the main organizational structure material in vacuum-formed refractory ceramic fiberboard products, which determines the basic performance of the product. Ordinary aluminum silicate refractory ceramic fiber, high aluminum refractory ceramic fiber, zirconium-containing refractory ceramic fiber and polycrystalline alumina ceramic fiber can be used according to different requirements. Binders can be silica sol, aluminum dihydrogen phosphate, carboxymethyl cellulose and aluminum sulfate. Fillers include clay, high aluminum clinker powder, alumina powder, expanded perlite, fused silica, etc.
