The glass fiber puncture filter felt bag is prepared with a reactive fluoride additive mixed with a working fluid to impregnate the filter material, so that the working fluid reacts with certain groups in the macromolecular structure of the filter material fiber to form a macromolecular chain.
Glass fiber puncture filter felt cloth bag is prepared with reactive fluoride additive mixed with working fluid to impregnate the filter material, so that the working fluid reacts with certain groups in the macromolecular structure of the filter material fiber to form a macromolecular chain and change the fiber with water and oil. The affinity property reduces the surface tension of the filter material to less than the surface tension of water and oil to achieve the purpose of water and oil repellency. Various filter materials of glass fiber stabbing filter felt bag are treated with water-repellent and oil-repellent agent, which can form a molecular barrier around the fiber surface, which can prevent water and various oil stains from adhering and penetrating. Compared with ordinary filter materials, it not only has water-repellent and oil-repellent properties. Characteristics, and for dust, it also has anti-adhesion and easy peelability. Glass fiber stabbing filter felt bag is particularly suitable for filtering occasions in southern China or rainy areas and high air humidity.
