During operation of the bag filter , the gas contains more moisture and dust and oily dust deliquescent hygroscopic and easy , it is possible to generate a water film on the surface of dust or the film adhesion is increased , although this helps catch Dust collection , but it will make it difficult to clean the dust . Especially when the high temperature gas is in a high humidity state , condensation will occur due to the cooling effect of the external gas . This will not only cause the trapped dust to scale on the surface of the filter bag , or even clogging , but also corrosion of the structural material , so that dust increased running resistance , direct impact on the normal operation of the bag filter . in view of this , ordinary filter must be further improved in function , to suit this special working conditions To prevent or reduce the phenomenon of dust paste bag and improve the service life and work efficiency of the filter material. In recent years , our company has used reactive fluoride additives to post-treat various filter materials such as polyester, polypropylene, anti-static needle felt aramid needle felt, etc. , and achieved ideal water and oil repellent effect . Not only water and oil repellent The grade test meets the national standard and does not affect the appearance style and internal indicators of the original needle felt . Water repellent and oil Mechanism: formulated with reactive fluoride impregnated filter auxiliaries fluid , the working fluid in the macromolecular structure with a fibrous filter certain groups reacted , forming macromolecular chain, changing the fiber with water, oil affinity can , the surface tension of the filter is reduced , to less than the surface tension of water and oil , in order to achieve the purpose of water repellent and oil . after the water- and oil-repellent treated by a variety of media , can form a molecular barrier around the fiber surface , may be and all kinds of material to prevent water buildup and oil penetration . compared with the general media , not only with a water repellent and oil properties, but also in terms of dust , also has anti-adhesion and easy peeling . the product is especially suited to China''s rainy south or Area and air humidity filter .
