Polyester needle felt bag
In addition to the advantages of high porosity, good air permeability, high dust collection efficiency and long service life, the polyester needle felt dust bag has the characteristics of moderate temperature resistance, which can reach 120 ° C in an instant, moderate acid resistance and alkali resistance, and has Very good wear resistance, so it is a widely used variety in felt filter media.
Anti-static polyester needle felt
Acid and weak alkali resistance. Wear resistance, corrosion resistance, recovery are very good, electrical conductivity is very poor. Heat resistance: 130°C, elongation at break (%): 20-50, strength at break (g/d): 438. Melting point (°C): 238-240, melting point (°C): 255-260. Specific gravity: 1.38. Polyester anti-static needle felt has smooth surface, good wear resistance, high strength, higher strength and better wear resistance after twisting, so the fabric has good air permeability, fast water leakage and easy cleaning.
Coated polyester needle felt
Features of coated polyester needle felt: large air flow, low resistance, good filtration efficiency, large dust holding capacity, and high dust stripping rate. It is the best filter material for sterilization and dust removal. Polyester felt and PET film can be made into various filter bags, filter cartridges and filters, which are widely used in the treatment and recovery of flue gas and dust particles in cement, metallurgy, food, coating, petrochemical plastics and other industrial fields.
Water and oil repellent polyester needle felt
Polyester needle-punched felt water-repellent and oil-repellent dust-removing bag can effectively prevent water and various oily dirt from attaching and penetrating. Compared with ordinary filter materials, it not only has water-repelling and oil-repelling characteristics, but also has anti-caking and easy-flaking properties for dust. For the dust entering the bag filter containing more water and oily and hygroscopic and deliquescent dust, a water film may be formed on the dust surface to increase adhesion.
