Dust bag laminating film breathable dust bag capacity, low resistance, good filtration efficiency, dust holding capacity, high dust stripping is the best filter sterilization, dust. Microfiltration: After PET, PP film can be made, such as non-woven filter and filters for chemical, pharmaceutical, electronics and other industries, both micro-particle filtration and isolation of bacteria while maintaining a high filtration efficiency and low flow resistance . First, the product features an integrated performance fiber needle felting, corrosion resistance and improve the overall efficiency of the filter needle felt, but also has a strong cohesion between the winding force irregular cross-section fibers, carpet and fabric to make between the binding force enhancement, even filtration velocity increases, the blanket is not easy to peel off from the fabric, raise the level of impact resistance and pressure filter to reduce the damage and bag bag deformation, this structure needle felt filter permeability increased collection efficiency is the best filter; glass fiber and high temperature, acid fibers mixed in proportion, the new filter material by combing, acupuncture, chemical processing and other processes and made; introduction of microfiber As the surface of the surface layer can be more dense needle felt, to improve the ability to capture fine dust, and dense surface cleaning easier, so that the filter can maintain long-term stable operation at a lower operating resistance; temperature synthesis fiber glass fiber low coefficient of friction protection against mechanical damage, such needle felt stripped of dust, acid corrosion, high collection efficiency; PTFE coating on the surface of synthetic felt filter to further enhance moisture, corrosion resistance . For iron and steel, smelting, cement, chemicals, waste incineration, industrial waste incinerators, coal-fired boiler flue gas dust and other occasions. http://www.hdcchb.com
