Glass fiber filter bag is a kind of high temperature resistant filter material with reasonable structure and good performance. Anti-static fiberglass filter bag not only has the advantages of fiberglass fabric with high temperature resistance, corrosion resistance, dimensional stability, minimal elongation and contraction, and high strength, but also the felt layer fiber supports single fibers, has a three-dimensional microporous structure and high porosity. It has low resistance to gas filtration and is a high-speed, high-efficiency high-temperature filter material. Compared with other high-temperature resistant chemical fiber felts, it has special advantages such as low price, low running resistance, high filtration accuracy, and higher temperature resistance. It is suitable for high-temperature flue gas filtration in steel, metallurgy, carbon black, power generation, cement, chemical and other industries.
