         During the operation of the bag dust collector, water film or oil film may be formed on the dust surface and the adhesion will increase, but it will be difficult to clean the ash, and the condensation phenomenon will occur due to the cooling effect of the external gas, and even clogging. The running resistance of the dust collector is increased. In view of this, the service life and working efficiency of the filter material can be improved by applying this special working condition.


In recent years, our company has selected reactive fluoride additives for post-treatment of various filter materials such as polyester fiber, polypropylene fiber, antistatic needle felt, aramid needle felt and other filter materials, all of which have achieved ideal water and oil repellency and oil repellent effect, not only water and oil repellent grade tests have reached the national standard. And does not affect the original needle felt appearance style and internal indicators.

The mechanism of water repellent and oil repellent: the filter material is impregnated with the mixed working fluid with reactive fluoride agent, which reacts with some groups in the fiber macromolecular structure of the filtrate, forms a macromolecular chain, and changes the affinity of the fiber with water and oil. The surface tension of filter media is reduced to less than that of water and oil, so as to achieve the purpose of water and oil repellent. After treated with water repellent oil repellent, all kinds of filter materials can form molecular barrier around the surface of fiber. It can prevent water and all kinds of oil pollution from sticking and permeating. Compared with ordinary filter material, it not only has the characteristics of water and oil repellent, but also for dust, The product is especially suitable for filtration in southern China or in rainy areas and in high air humidity.
