Alkali-free glass fiber filter

The alkali-free glass fiber filter material is a filter material with excellent alkali resistance woven by the non-alkali glass fiber formed by the chemical treatment of the glass fiber yarn before weaving, and the alkali-containing gas is contained in the equipment room. When the medium-alkali glass fiber filter material does not have alkali resistance, it is easily corroded by the gas. At this time, the alkali-free glass fiber cloth woven by the alkali-free glass fiber yarn having the alkali resistance can be used. It is completely suitable for the filtration of soda-containing flue gas, and there is no corrosion of the filter material.
