water-repellent and oil-proof polyester needle felt dust bag

Usage Introduction

water-repellent and oil-proof polyester needle felt dust bagis formed by the use of hydrophobic agents and oil repellents by padding, pre-baking and baking. Hydrophobic agent and oil repellent agent after rapid drying, with mesh package attached to the surface of the filter fiber, thereby reducing the surface tension of water and oil and filter bag, so that water, oil and dust formed wet filter medium will not adhere to the surface of the filter bag, thus avoiding the paste bag phenomenon.

Specific Features

water repellent and oil repellent polyester needle felt dust bag is 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 larger.

Under normal circumstances, if the acidity of the dust-containing gas is very small, its dew point temperature is 40-60°C. If the acidity is large, the dew point temperature may be as high as 120°C.
water-repellent and oil-proof polyester needle felt dust collector bag is as follows: fiber opening-carding-netting-pre-stab-main stab-felt-singeing-calendering-impregnated PTFE (waterproof agent)-drying-shaping-rolling-packaging.
filter cloth by waterproof and oil-proof treatment of the filter bag application in the moisture content of the larger occasions, compared with ordinary filter bags, because the filter material is not easy to block the paste bag, so the bag service life and ash removal cycle can be extended, through the gas flow is also increased, it can save a lot of energy consumption and maintenance costs.
