Our company will produce different filter materials and different specifications of dust bag products according to customer requirements. Among them, the filter cloth for anti-static dust bags is made of
. . Water-repellent and oil-proof cloth 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 filter bag, thus avoiding the bag sticking phenomenon
. Water-repellent and oil-proof cloth 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 dusty gas is very small, its dew point temperature is < ℃ ℃. If the acidity is large, the dew point temperature may be as high as < ℃ < ℃ ℃. The production process of water-repellent and oil-repellent needle-punched felt is as follows: fiber opening
carding
web laying
pre-punching
main pricking
felting
singeing
Calendering
Impregnation

Coiled. Filter bags whose filter cloth has been treated with waterproof and oil-proof treatment 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 cleaning cycle can be extended. The gas that passes through The flow rate is also increased, so energy consumption and maintenance costs can be greatly saved.
