Water and oil repellent polyester needle felt filter bag is acupuncture, the use of hydrophobic and oleophobic agents by padding, pre drying, baking and forming. Hydrophobic and oleophobic agent by fast drying, the surface of a mesh bag attached to the filter fiber, thereby reducing the surface tension of water and oil, and so the water bag, wet filter media to form oil and dust will not stick to the surface of the dust bag, so as to avoid the phenomenon of paste bags.
Water and oil repellent polyester needle felt filter bag is usually lower than the dew point temperature in the precipitator box temperature, the use of dust containing gas and humidity of the larger.
Under normal circumstances, if the acidity of the dust containing gas is very small, the dew point temperature of 40-60 C if the acidity is larger, the dew point temperature may be as high as 120 degrees Celsius.
Water and oil repellent polyester needle felt filter bag production process is as follows: fiber opening - sort - Shop Network -- the main thorn thorn - pre -- -- -- -- felt singeing calendering impregnated PTFE (water repellent) drying stereotypes -- rolling roll.
The waterproof cloth bag filter application of oil treatment in high moisture content of the occasion, compared with ordinary bag, because the filter clogging paste bag, the bag and prolonging the service life of the cleaning cycle can be prolonged, the gas flow through the increase, it can greatly save energy consumption and maintenance costs.
