The high-end building material series of wollastonite fiber has the advantages of non-toxic, odorless, and non radioactive, gradually replacing asbestos, which is harmful to human health, and is a new raw material for environmentally friendly building materials in the new century. Wollastonite fibers can still maintain their unique needle like structure after special processing technology, and the impact resistance, bending strength, and wear resistance of materials such as silica calcium board and fireproof board with added wollastonite fibers are greatly improved.
