Water repellent and oil resistant needle punched felt dust bag

Water repellent and oil resistant dust filter bags can effectively prevent water and various oil pollutants from seeping in. Compared with ordinary filter materials, they not only have water repellent and oil resistant characteristics, but also have anti caking and easy peeling properties for dust.

Water repellent and oil resistant needle punched felt dust bag

The water repellent and oil resistant polyester needle punched felt dust bag can solve the problems of bag sticking and difficult dust cleaning during the operation of bag filters. For dust containing a lot of moisture and oil, as well as hygroscopic and deliquescent dust in the gas, water or oil films may form on the surface of the dust, increasing adhesion. Although this helps the dust filter bag capture dust, it will make it difficult for the dust filter bag to clean dust. Especially when high-temperature gases are in a high humidity state, condensation occurs due to the cooling effect of external gases. This not only causes the dust collected by the dust removal filter bag to scale and even clog on the surface of the filter bag, but also corrodes the structural materials, increasing the operating resistance of the dust collector and directly affecting the normal operation of the bag filter. In view of this, the ordinary filter material dust removal filter bag has further improved its function, namely, water and oil repellent treatment, to adapt to this special working condition, prevent or reduce the phenomenon of dust sticking to the bag, and improve the service life and work efficiency of the dust removal bag of the dust collector.
In recent years, our company has been producing polyester waterproof materials in response to customer demandOil proof and dust removal filter bagPolypropylene waterproof materialOil proof and dust removal filter bagThe water and oil repellent needle punched felt (three proof) dust removal filter bag and aramid needle punched felt waterproof and oil proof dust removal filter bag have excellent water and oil repellent effects.
Water repellent and oil resistant polyester needle punched felt dust bag is suitable for industries such as cement plants, wood processing plants, and smelters.
Mechanism of water and oil repellent filter material: A reactive fluoride additive is used to prepare a mixed working fluid to impregnate the filter material, causing the working fluid to react with certain functional groups in the fiber macromolecular structure of the filter material, forming macromolecular chains, changing the affinity between the fiber and water and oil, reducing the surface tension of the filter material to less than that of water and oil, in order to achieve the purpose of water and oil repellent. After being treated with water and oil repellent agents, various filter materials can form molecular barriers around the fiber surface, which can prevent water and various oil pollutants from adhering to and penetrating. Compared with ordinary filter media, it not only has water and oil repellent properties, but also has anti adhesion and easy peeling properties for dust. This product is particularly suitable for filtering applications in southern or rainy areas of China, as well as in areas with high air humidity.
Filter material production process: fiber loosening - combing - mesh stacking - pre needle punching - main needle punching - calendering - immersion in water repellent and oil proof working fluid - baking - heat setting - finished product
