Product Description
Our company produces anti-static needle-punched filter felt filter bags based on the characteristics of blast furnace gas coal mill dust collection and cement factory coal mill dust collection and the needs of other industries. The use of striped conductive base fabric can make the filter material have anti-static function. Conductive fibers or stainless steel conductive materials are mixed into the surface fibers to make the antistatic performance more excellent.
According to the different requirements of working conditions, the surface treatment can be singeing, calendering, water and oil repellent, PTFE impregnation, coating, coating and other treatments.
Polyester Needle Felt
Polyester room temperature needle punched felt is a non-woven needle punching process that uses staggered fibers and uniformly distributed fine fiber cloth. The surface of the needle punched felt produced by polyester staple fiber and polyester twisted yarn is hot rolled, singed or coated After the post-treatment, the surface is smooth and not easily blocked by dust. This filter has a large porosity, good air permeability, wide range of uses, and strong chemical resistance. It can filter not only normal temperature gases, but also acids and alkalis. Corrosive gas, and can filter water and oil, is the ideal filter material in the field of normal temperature, liquid-solid separation and other fields.
performance
1. Polyester needle punched felt is made of thin and short fibers with staggered arrangement and uniform pore distribution. The porosity is 70%, which is double that of woven filter cloth.
2. High dust removal efficiency and low gas emission concentration.
3. The surface of the polyester needle-punched felt is hot-rolled, singed or coated, and is smooth and smooth. It is not easy to block, deform, and clean, and has a long service life.
4. Anti-static needle-punched felt has the function of anti-corrosion and anti-static discharge of blast furnace gas and coal mill bag of cement plant, and the discharge of static electricity.
