Product Detail
Main Types of Anti-Static Needle Felt
Intoduction
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.
