The carbon black special filter bag is made of porcelain kiln non-alkali yarn woven fabric. The product has excellent performance, high temperature resistance, acid resistance, alkali resistance and corrosion resistance. The carbon black stripping performance is good, and it is easy to clean. The use of filter bags is not affected by changes in working conditions. It is a high-efficiency filter material for soot and the chemical composition of the collected products, dust particle size, water content, etc.
