Glass Fiber Woven Fabric Filter Bags: Green Protection Barrier for High-Temperature Industries

In the field of industrial flue gas treatment, glass fiber woven fabric filter bags have become an important dust removal tool in cement, metallurgy, power and other industries due to their high temperature resistance, corrosion resistance and high cost performance. This filter bag is made of medium-alkali or alkali-free glass fiber, and is made through twisting, weaving and surface treatment processes. It can not only withstand long-term high-temperature operation, but also has air permeability and dust removal properties, providing an effective filtration solution for high-dust and high-corrosion industrial scenes.

The core of glass fiber woven fabric filter bags lies in their unique fiber processing process. Medium-alkali glass fiber is impregnated with graphite or silicone oil to form a smooth protective layer on the surface, which not only improves the tolerance to acidic gases, but also reduces the dust adhesion rate. For working conditions containing alkaline flue gas, traditional medium-alkali glass fiber filter bags are prone to brittle fracture due to corrosion by components such as Na₂O. The alkali-free glass fiber filter bag is made of E glass fiber, and a protective film is formed on the fiber surface through chemical vapor deposition process to extend the service life of the product.

Glass fiber filter bags can flexibly adapt to different industrial needs and have lower costs. They are ideal filter materials for high-temperature dust removal companies.
