Polyester anti-static needle felt has the characteristics of acid resistance, weak alkali resistance, oxidation resistance, high tensile strength, good heat and humidity resistance, mildew resistance and high working temperature. According to the requirements of the fabric, polyester anti-static needle felts are made of different specifications of raw materials and different structures to form various products with different filtering performance and appearance.
Polyester anti-static needle felt products are mainly used in chemical, metallurgy, food, pharmaceutical, building materials, mining and other industries as bag filter, plate and frame filter press, belt filter, vacuum suction filter and filter equipment for liquid dust removal and solid gas separation.
If the concentration of industrial dust reaches a certain level, such as electrostatic discharge spark or external ignition, it is easy to cause explosion and fire. For example, flour dust, chemical dust, coal dust, etc. may explode if exposed to electrostatic discharge. In the field of bag dust removal, if the dust needs to be collected by a cloth bag, it is required that the filter bag for making the dust bag has antistatic property.
