When the concentration of industrial dust reaches the explosion limit, it becomes highly susceptible to causing explosions and fires when exposed to factors like electrostatic discharge sparks. This is especially true for dust types such as flour, chemicals, and coal. To collect these dusts using cloth bags, it is crucial to use filter bags with anti-static properties. The production of anti-static filter material involves incorporating conductive fibers into the warp yarn of the base fabric or mixing them with chemical fibers during the production of needle felt. There are various types of anti-static needle felts available, including polyester and aramid blends in different configurations. These felts exhibit excellent anti-abrasion properties and have a surface resistance ranging from 103 to 108(Ω.cm). Customization options are also available to meet specific requirements. Our commitment to quality is evident in our rigorous testing process, where each material undergoes extensive experimentation to ensure stability and prolong its service life.
Application
Antistatic needle punched filter fabric is primarily utilized in dust bag items, with the main applications in the following industries:
1. Cement production, including grinding, packaging, and transportation.
2. Smelting operations, such as sintering machines and continuous casting.
3. Mining activities, particularly in collecting limestone powder.
4. Non-ferrous metal factories, for alumina transportation and electrolytic aluminum.
5. Furniture manufacturing, specifically in grinding workshops.
6. Dust collection in grain processing.
7. Dust collection in pharmaceutical and various other industries.
