The outstanding advantages of glass fiber composite filter bags are high temperature resistance and can be used at high temperatures of 260-280°C. They have good dimensional stability and high tensile strength, which is more than twice that of synthetic fiber filter cloths. In terms of chemical corrosion resistance, in addition to strong acids such as hydrofluoric acid and high temperature and strong alkali, it is stable to other media, but its disadvantage is poor folding resistance. It cannot be used to purify industrial kiln flue gases where fluorspar is added or HF acid is present during smelting.
