Polyester normal temperature needle felt is a fine fiber cloth which adopts a non-woven needle punching process and uses fiber staggered and evenly distributed. The surface of the needle felt produced by polyester staple fiber and polyester crepe is hot rolled, singed or coated. After the treatment, the surface is smooth and not easy to be blocked by dust. The filter material has large void ratio, good gas permeability, wide application, strong chemical stability, not only filtering normal temperature gas, but also filtering acid and alkali. Corrosive gas, and can filter water, filter oil, is the ideal filter material in the field of normal temperature conditions, liquid-solid separation.
performance
- Polyester needle felt is a fine short fiber filter with staggered arrangement and uniform pore distribution. The porosity is 70%, which is double the woven filter cloth.
- High dust removal efficiency and low gas emission concentration.
- The surface of polyester needle felt is hot-rolled and singed or coated, smooth and smooth, not easy to block, not deformed, easy to clean, and has a long service life.
- Anti-static needle felt has the function of preserving the electrostatic discharge of blast furnace gas and coal grinding bag of cement factory, and extracting static electricity.
