This is a new type of high-temperature and high-efficiency filter material with reasonable structure and excellent performance. It not only has the advantages of high temperature resistance, acid and alkali corrosion resistance, dimensional stability and high strength of glass fiber woven filter material, but also uses 100% alkali-free glass fiber as raw material. It adopts high-country glass fiber silk to form a needle-punched needle, which has good heat resistance, flame retardant, anti-corrosion effect, low gas filtration resistance, dust removal efficiency over woven filter material, and filtration speed higher than woven filter material. It is the first choice for purifying blast furnace gas and flue gas filtration in industries such as steel and refining.
