PTFE filter bag is made of 100%PTFE without adding any other raw materials and additives, which does not change the original characteristics of PTFE. Therefore, the filter bag has the characteristics of high temperature resistance, strong acid and alkali resistance, good friction resistance, difficult combustion and good insulation.Our company adopts the international advanced double-layer interlock sealing sewing bag making structure, this kind of stitching structure does not take off the thread, the press cloth itself is not smooth, does not deform, the structure is stable, the strength is high, the service life of the filter bag is effectively extended. In addition, the increase in the amount of cloth increases the thickness. The penetration ability of dust from the suture is almost zero, which can ensure the discharge reaches the standard value, Widely used in incineration dust collection, chemical dust removal and other harsh working conditions.
