Polyester Filter Bag Dust Filter Bags Polyester Needle Felt Filter For Cement Dust
Polyester filter bag Polyester needle felt filter for cement dust
Product description
Polyester normal temperature needle-punched felt is a thin fiber cloth with interlaced fibers arranged in a non-woven needle-punched process and uniform gap distribution. The surface of the needle-punched felt produced by polyester staple fiber and polyester twisted yarn is hot rolled, singed or coated After post-treatment, the surface is smooth and not easy to be blocked by dust. The filter material has a large porosity, good air permeability, a wide range of uses, and strong chemical stability. It can not only filter room temperature gases, but also filter acids and alkalis. It can filter water and oil. It is an ideal filter material for normal temperature working conditions, liquid-solid separation and other fields.
