Polyester needle punched felt filter bag is a common type of dust collector filter bag, which has certain performance such as acid and alkali resistance, high temperature resistance, and wear resistance, and is commonly used in the field of flue gas emission treatment. The technical parameters are as follows:
Material: Usually made of polyester fiber and processed into polyester needle felt filter bags.
Specifications: Generally based on length and diameter, the length can be customized according to needs, and the diameter is usually between 100mm-200mm.
Thickness: Different thicknesses of polyester needle felt filter bags can be selected according to needs, usually between 1.8mm and 3.0mm.
Weight: Usually calculated based on the weight per unit area, typically between 450g/m2 and 800g/m2.
Air permeability: refers to the volume of gas passing through the filter bag per unit time, usually between 8-15m3/m2. min.
Breaking strength: refers to the breaking force of a filter bag when subjected to a certain tensile force, usually between 800N/5cm and 2000N/5cm.
Temperature resistance: Polyester needle punched felt filter bags can generally withstand high temperatures of 120 ℃ -150 ℃, but temperature resistance is also related to specific processing techniques.
