Alkali-free expanded glass fiber filter
Alkali-free expanded glass fiber filter

The alkali-free expanded glass fiber cloth is a new type of high-efficiency filter material developed on the basis of continuous alkali-free glass fiber cloth. The difference from the continuous alkali-free glass fiber cloth is that the weft yarn is made of alkali-free glass fiber bulked yarn. The composition, because the yarn is fluffy, has high coverage and good gas permeability, thereby improving filtration efficiency and reducing filtration resistance. Since the alkali-free glass fiber itself has good alkali resistance, it can effectively capture the alkaline dust in the flue gas, and the filter material can effectively prevent the alkali-containing gas from corroding the filter material, thereby The device is in normal operation.

Jiangsu Jinke specializes in the supply of silicone bags and other products. Welcome to consult.
