Hebei Qiaoda wheel needle felt dust bag waterproof and oil-proof cloth bag production and customization

Water-repellent and oil-proof filter bags are made of needle-punched nylon using hydrophobic and oleophobic agents through padding, pre-baking and baking. After the hydrophobic agent and oleophobic agent are quickly dried, they are attached to the surface of the filter fiber in a mesh shape, thereby reducing the surface tension between water, oil and the filter bag, so that the wet filter media formed by water, oil and dust will not It will adhere to the surface of the dust removal filter bag, thus avoiding the bag sticking phenomenon. Water-repellent and oil-proof filter bags are usually used when the temperature of the dust collector box is lower than the dew point temperature and the humidity of the dust-containing gas is high. Under normal circumstances, if the acidity of the dust-containing gas is very small, its dew point temperature If the acidity is high, the dew point temperature may be as high as ℃br/> The production process of water-repellent and oil-proof filter bags is as follows: Fiber opening, carding, laying, pre-thorning, main stabbing, felting, singeing, calendering, impregnation (waterproof agent), drying, shaping and rolling Made into rollsbr/> Filter bags whose filter cloth has been treated by waterproofing and oil-proofing are used in situations with high moisture content. Compared with ordinary filter bags, the filter material is less likely to block the paste bag, so the service life of the bag is extended and the dust cleaning cycle is longer. It can be extended and the passing gas flow rate is also increased, so it can save a lot of energy consumption and maintenance costs.
