The electrostatic polyester needle punched felt dust removal bag is made of polyester fine denier large fiber yarn, and the polyester (polyester) fiber needle punched filter felt is produced with excellent equipment. Multiple fibers can be evenly and quantitatively mixed, and multiple mixing and combing units can be used to facilitate the layering and gradient transformation between different fibers in the fiber web.
The electrostatic polyester needle punched felt dust removal bag has the advantages of high porosity, good breathability, dust collection, and long service life unique to ordinary felt filter cloth. Due to its moderate temperature resistance, it can instantly reach 150 ℃, and its moderate acid and alkali resistance, it is also a widely used type of felt filter material.
The smoothness of the filter surface of the electrostatic polyester needle punched felt dust removal bag has a significant impact on the dynamic operating resistance of the filter material. The initial resistance of the filter material is determined by the permeability of the filter material itself, and the resistance during operation is many times greater than the initial resistance.
The electrostatic polyester needle punched felt dust removal bag is divided into circular bag and trapezoidal bag.
Characteristics of electrostatic polyester needle punched felt dust bag:
1. High strength and low elongation industrial silk is used as the base fabric to significantly increase its strength.
2. Using fine fibers with reduced pore size, high porosity, and high filtration accuracy.
3. Using high-quality polyester fibers, the hydrolysis resistance is enhanced.
4. The surface treatment is smooth and has the surface filtration effect of membrane filter material.
5. Low operating resistance, saving energy.
