Polyester anti-static needle felt
Description:
It is easily resulted in the explosion and conflagration after the consistency of common industrial powder and dust reaches the certain degree (explosion limit) if touching the static electricity light and spark outside, such as flour powder, chemical dust, coal powder etc. In the field of the dedusting filter bag, if we use the bag to collect dust, then the filter medium for bags must be anti-static.
By combining the conducting fiber into the transversal yarn in the needle punched felt base cloth or the conducting fiber and conducting material into the chemical fiber. Or conductive by addition of the stainless steel thread in the scrim.
Application:
Areas subject to explosion hazards, for example, coal milling collecting
Filter dust with high electrostatic charge, for example, mill powder and dust collection
