Nanotechnology ultra-precision filtration and dust removal filter element

The dust filter element (canister) of Gu'an County Hongchang Filter Factory is mainly used for supporting the filter element (canister) type dust collector. This product uses imported composite fiber filter material (wood pulp fiber + polyester fiber), which is characterized by good filtration accuracy, Good stiffness and bursting resistance. Galvanized diamond-shaped steel mesh is used as the internal and external support to prevent rust. The upper and lower end caps are stamped from electric boards imported from South Korea. The wide pleat design is used to increase the filtering area, and elastic fluoroprene rubber is used as the sealing strip. Technical Description Our company's filter cartridge filter material is mainly made of polyester non-woven fabric produced by the spunbond method as the base material, and is made through post-processing. Currently, six series of filter media products have been developed. 1. Ordinary polyester non-woven fabric series 2. Aluminum coating series 3. Charged electrostatic series 4. Oil-proof, waterproof, anti-fouling series 5. Fluorine resin microporous membrane series 6. Coating series Among them (1) ~ The (4) series are depth filtration filter media, and the (5) to (6) series are surface filtration filter media. Ordinary polyester spunbond non-woven fabric has the characteristics of high strength, long service life, ability to withstand high filtration wind speed, low price, but low filtration accuracy. It is suitable for filtration of dust with low emission requirements, large particle size, dryness and low viscosity. The aluminum-coated series filter media is made of ordinary polyester non-woven fabric covered with a conductive aluminum coating. Mainly plays the role of anti-static and explosion-proof. In addition, oil-proof, waterproof, and anti-fouling functions can be added according to actual conditions. This series of materials is not suitable for use in places with acidity, alkalinity or high humidity. The oil-proof, waterproof and anti-fouling series filter materials are made of ordinary polyester non-woven fabrics with oil-proof, waterproof and anti-fouling treatments, making the filter material non-sticky. Therefore, the dust will fall off more easily during pulse backflush dust removal. The effect is more obvious in humidity conditions (especially suitable for large particle size dust that is easy to absorb moisture or high humidity situations). The fluororesin microporous membrane series filter material is a very thin layer covered on ordinary polyester non-woven fabrics. Uniform fluororesin microporous membrane. This series of filter media is a surface filtration type filter media. It has the characteristics of low price, high filtration accuracy, long service life, good air permeability and hydrophobicity. It is suitable for occasions with high emission requirements, small dust particle size and high humidity. Such as powder transportation, heavy metal dust, shot blasting and dust removal, powder spraying (especially secondary recycling), atmospheric dust removal, etc. The film-coated series filter materials are film-coated on ordinary polyester non-woven fabrics. In addition, flame retardant and water-resistant functions can be added according to the actual use situation. This series of filter media is a surface filtration type filter media. They all have the characteristics of high filtration precision, long life, good air permeability, and high price. After adding water resistance, they can be suitable for high-humidity environments. This series of filter materials is mainly suitable for welding fume treatment, ultra-fine powder transportation, filtration and recovery, etc.
