Pall pall welding high flow filter skeleton?

Pall pall high flow filter material adopts whole PP polypropylene material, in different forms. Filter material used PP membrane + composite film multi-layer fold, winding and then fixed inside and outside the frame adopts PP material thickness of the skeleton, compressive ability is stronger. Each frame is 10 inches, 40 inch frame welded together by section 4, so how to welding? Pall pall high flow filter skeleton USES the hot melt welding, hot melt process is to put the PP skeleton skeleton two joint, high temperature heating, the molecules in the PP matrix, to some degree, the powerful and docking, and molecules will again dissolves, after being end cooling, skeleton hot melt. Pall pall hot melt skeleton high flow filter used in this way, it is to prevent the adhesive process, in a high traffic environment, cause the pressure is too small, viscose, 2 it is hot melt, skeleton being stronger long service life.
