Repellent oil polyester fiber needled felt in bag filter operation process, for dust contained more moisture in the gas and oil and moisture absorption and deliquescence of dust, can generate in the dust on the surface of water or increase adhesion of oil film, it helps to trap dust, will be difficult to appear clear grey.
Repellent oil polyester fiber needled felt in bag filter operation process, for dust contained more moisture in the gas and oil and moisture absorption and deliquescence of dust, can generate in the dust on the surface of water or increase adhesion of oil film, it helps to trap dust, but will be difficult to appear clear grey.Especially the high temperature gas and is in a state of high humidity, due to the cooling effect of the external gas condensation phenomenon.This not only can make the dust catcher scale formation in the surface of filter bag, even congestion, but also material corrosion structure, increase the filter resistance, directly affects the normal operation of the bag filter.For this reason, the ordinary filter material must have further improve on the function, in order to apply the special working conditions, prevent or reduce dust paste bag, prolonging the service life of filter material and the work efficiency.
In recent years, my company's dust bag use reactive fluoride agent for polyester, polypropylene, anti-static needle felt, aramid fiber needled felt all kinds of filter material such as post-processing, are the ideal repellent oil results have been achieved.Repellent oil level test not only meet the national standards, and shall not affect the original appearance style and internal indicator of needled felt.
Repellent oil mechanism:
Prepared with reactive fluoride additives mixed working liquid impregnation filter material, make the working fluid and filter material react certain groups in the fiber macromolecular structure, the formation of macromolecular chain, change and properties of the fiber and water, oil, reduce the surface tension of the filter material, dropped to less than the surface tension of water and oil, repellent oil in order to achieve the purpose.
Production process:
Fiber opening - comb fold - net - to acupuncture - the main acupuncture - calender - dipping repellent oil working liquid - baking - heat styling - finished products
All kinds of filter material after repellent agent treatment, around the fiber surface molecules barrier, can prevent the water and all kinds of oil dirt stained with echo.Compared with ordinary filter material, not only with repellent oil properties, and to dust, but also has the caking property and easy to stripping resistance.This product is especially suitable for southern China or rainy areas and humidity of the air filter.
