The new filter material is made by mixing glass fiber and high-temperature, acid and alkali-resistant fibers in proportion, and through carding, needling, chemical treatment and other processes. The comprehensive performance fiber is needled into felt to improve the comprehensive anti-corrosion performance and filtration efficiency of the needled felt. At the same time, the fibers with irregular cross-sections have strong cohesion and winding force, which enhances the bonding force between the felt layer and the base fabric. Even if the filtration wind speed increases, the felt layer is not easy to peel off from the base fabric, improving the filter material's performance. Impact resistance and pressure resistance, reducing bag damage and bag deformation. This structure of needle felt filter material increases air permeability and is currently the filter material with the best dust collection efficiency
Introducing ultra-fine fiber as the surface layer can make The surface of the needle felt is denser, and its ability to capture fine dust is improved. At the same time, the dense surface is easier to clean, allowing the filter material to maintain long-term stable operation at a lower operating resistance
High temperature resistant synthetic fiber is low The friction coefficient protects the glass fiber from mechanical damage. This kind of needle felt has good dust peeling performance, acid and alkali corrosion resistance, and high dust collection efficiency. Coating the surface of the synthetic fiber felt further improves the moisture resistance and corrosion resistance of the filter material.
It is suitable for flue gas dust removal in steel smelting, cement chemical industry, waste incineration, industrial waste incinerator, coal-fired boiler and other occasions.
