The principle of water and oil repellent filter bag:
The reactive working fluid is used for preparing the impregnated filter medium with the reactive fluoridating agent, so that the working fluid reacts with certain groups in the macromolecular structure of the filter fiber to form a macromolecular chain, which changes the affinity between the fiber and the water and oil, so that The surface tension of the filter material is reduced to less than the surface tension of water and oil in order to achieve the purpose of water repellency and oil repellency.
Production Process:
Fiber opening — carding — stacking network — to acupuncture — main acupuncture — calendering — impregnation water and oil proof working fluid — baking — heat setting — finished product
After being treated with water-repellent and oil-repellent agents, various filter media can form a molecular barrier around the surface of the fiber, preventing the adhesion and penetration of water and all kinds of oil dirt. Compared with ordinary filter media, it not only has water-repellent and oil-repellent properties, but also has anti-adhesion and easy-to-peel properties for dust. This product is especially suitable for filtration occasions in southern China or in rainy areas and with high humidity.
