After the general industrial dust reaches a certain level (ie, the explosion limit), such as electrostatic discharge sparks or external ignition, it is easy to cause explosion and fire. The 
factory absorbs and digests foreign technology, according to domestic blast furnace gas coal dust collection and cement. The company needs to develop and produce antistatic needle-punched filter felt and filter cloth for coal dust collection and other industries.

In addition to the process of producing ordinary needle felt, the production of antistatic filter cloth also requires the incorporation of conductive fiber yarns into the warp yarns of the base fabric of the needle felt or the incorporation of conductive fibers or conductive materials into the chemical fibers. Anti-static filter cloth can be produced by 
our company The performance index of anti-static needle-punched filter felt and filter cloth produced by our company is at the leading level in China. It has been tested by authoritative departments as follows:
