The Role of Filter Core in Air Filter
As an important part of the filter, the filter core has played a pivotal role in the filter. PP filter core is also called PP melt-blown filter core. Generally speaking, melt-blown filter core is made of polypropylene microfiber hot melt winding, the pore diameter along the filtrate flow is gradient distribution set surface, deep, in the fiber in the space randomly formed three-dimensional micropore structure, can trap impurities of different sizes. Its flux is more than 1.5 times that of the same precision peak house filter core, and different types of end caps can be configured to meet the needs of various engineering installations.
The filter core can be divided into many types according to classification, common wired wound filter core, folding microporous filter core, and compressed activated carbon filter core. The wire-wound filter core is made of textile fiber yarns with good filtering performance precisely wound on the porous skeleton. It can effectively remove the particles of various liquids, as well as suspended solids, etc., and has a high purification effect on various liquids. The yarn materials of the folding filter core are acrylic fiber, polypropylene fiber and absorbent cotton fiber. By controlling the winding tightness and thin density of the yarn, the filter core with different precision can be made. Folding microporous filter core. Folding microporous filter core is made of polypropylene thermal spray fiber film, and the sealing of the end cover of filter core and the overall structural connection are made of hot melt bonding. Nylon polytetrafluoroethylene microporous filter membrane is a precision filter device made of filter media, which has the advantages of large filter area, small volume and high precision. Filtration accuracy ranges from 0.1μm to 60μm.
Products are strictly tested before leaving the factory to ensure the stable performance of the product. Finally, there are two categories of activated carbon filter products: compressed activated carbon filter and bulk activated carbon filter. The compressed activated carbon filter is made of coal activated carbon and coconut shell activated carbon with high adsorption value as filter material, and is sintered and compressed by food-grade adhesive. The compressed activated carbon filter is wrapped with a layer of non-woven fabric with filtering effect inside and outside to ensure that the carbon core itself will not drop carbon powder. The carbon core is equipped with soft rubber gasket at both ends. The purpose of this design is to make the carbon core into the filter cartridge with good sealing. It seems that the role of the filter core in the entire filter is indeed playing an important role.
