In reality, due to the increasingly stringent requirements for industrial dust removal emissions (dust emission concentration ≤ 10mg / Nm3), it is necessary to coat the surface of the needle felt with PTFE. However, the stainless steel antistatic needle felt in the fiber layer has a large hardness and is very easy to break and puncture the PTFE film on the surface, causing dust leakage hazards.
