1. the present invention relates to a kind of air filtration filter material, specifically a kind of electrically charged polypropylene gauze air filtration filter material, it is characterized in that electrically charged polypropylene gauze air filtration filter material mainly adopts polypropylene chemical fiber gauze, make it bring for a long time after High Density Charge as air filtration filter material by HV generator.Its filtration mechanism is on the basis of traditional mechanisms, add new electrostatic effect mechanism.The polypropylene filamente fiber told, is spun into 33 spindles through spinning machine.The use told 33 spindles, through warping technology, make warp shaft.Told in rapier loom, utilize 33 warp shafts and 33 spindles, be woven into the polypropylene gauze in 1.5mm ×

  • 1.5mm aperture.The woven equal aperture polypropylene gauze told, average rate by ultrasonic wave hot melt adhesive machine, makes the thawing of the polypropylene fibre yarn of warp of the polypropylene gauze in 1.5mm ×

    1.5mm aperture, latitude knot point and bonding.The polypropylene gauze through supersonic thermal setting told, then by tunnel type air-cooling machine air-cooling moulding.Polypropylene gauze after the air-cooling moulding told, average rate by high-pressure electrostatic lotus generator, carries out the electrically charged process of high density with corona method, makes that it is long-term, High Density Charge on stabilized zone.Told electrically charged after polypropylene gauze, through the process of anti-electric charge escape device, make its charge density stablize.Electrically charged polypropylene gauze after the anti-electric charge escape process told, through lapper rolling, packaging, namely becomes electrically charged polypropylene gauze air filtration filter material.
