In addition to the advantages of the ordinary filter, the dacron water proof filter bag produced by weide has a series of characteristics such as anti-oil and moisture-proof.high strength and low stretch industrial silk as base cloth, making the strength greatly improved selects fine denier fiber, narrow aperture, high porosity and high filtration precision was used to optimize the hydrolysis of acid and alkali the surface treatment of is smoother and has the surface filtering effect of coated filter material runs small resistance and saves energy.
Production process: fiber opening - comb fold - net - to acupuncture - the main acupuncture - calender - dipping repellent oil working liquid - baking - heat styling - finished products
Repellent oil mechanism: prepared with reactive fluoride additives mixed working liquid impregnation, working liquid and the filter material response from the fiber in the macromolecular structure of certain groups, macromolecular chain formation, 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. 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 on echo penetration, waterproof grade level 5 above, can effectively reduce the dust deposition/agglomerate, prevent paste bag phenomenon, to ensure the safety of dust collector.
Application:
This product is suitable for the situation of high moisture content, such as blast furnace spraying powder, cement plant and power plant coal conveying system.
