Waterproof and oil-proof filter material

It can prevent water and various oils from adhering and infiltrating, and it’s also resistant to adhesion and easy to peel off. The filter cloth is used in applications with large moisture content, especially for rainy areas and high huity air filtration.

The production process of water-repellent and oil-repellent needled felt is as follows:

Fiber opening, carding and net prepricking, main pricking, felt burnished, calendering, impregnating, PTFE(water-proofing agent) drying, finalizing, rolling and rolling.

Filter bags after water-repellent and oil-repellent treatment are used in occasions with high moisture content. Compared with ordinary filter bags, the filter materials are not easy to block the paste bags, extending the ash removal cycle and the service life of filter bags. The flow through the gas also increases, saving energy and maintenance costs, while also increasing production. In addition to water-repellent and oil-repellent treatment for needle-punched felt (such as polyester, polypropylene, anti-static, metas), water-repellent and oil-repellent treatment can also be carried out for woven filter materials such as polyester 208 flanneles and 729 cylinder cloth.
