The production process of water-repellent and oil-proof needling filter felt is as follows:
Fiber opening-carding-laying-netting-pre-puncture-main thorn-felting-scorching-calendering-impregnated PTFE (waterproofing agent)-drying-shaping-rolling- -Package. After being treated with water and oil repellency, the filter cloth has a hydrophobic property on the surface. It prevents paste bags in the application, does not block the pores, is easy to ash, and has chemical properties such as acid and alkali resistance.
The filter cloth of water-repellent and oil-repellent room temperature dust-removing cloth bag is calendered and impregnated with PTFE (waterproofing agent), and it is used in places with a large humidity temperature. The filter material is not easy to block the paste bag, the service life of the dust bag is prolonged, and the gas flow is increased, which saves a lot of maintenance costs.
Water- and oil-repellent normal temperature dust-removing cloth bag can effectively prevent water and various oily dirt from adhering and permeating. Compared with ordinary filter materials, it not only has water- and oil-repellent properties, but also has anti-caking and easy peeling properties for dust.
Filter bags with water- and oil-repellent treatment are applied to the occasions with large moisture content. Compared with ordinary filter bags, because the filter material is not easy to block the paste bag, the service life of the bag is extended and the cleaning cycle can be extended. The gas flow is also increased, so it can save a lot of energy and maintenance costs.
