Teflon sintered glass process characteristics
After pre-treatment of glass fiber cloth and polytetrafluoroethylene, the sintering process, after repeated sintering, so that each fiber of the surface of the glass fiber cloth wrapped PTFE layer of dense protective layer, and the modulation PTFE Add another chemical additive solution of ethylene lung, suitable sintering temperature, speed, pressure, etc. The process control, the increase in the degree of crystallinity of the PTFE molecule, the Teflon fiberglass fabric adhesive strength and the degree of softness, and in order to improve adhesion. Higher degree of crystallinity, since molecules, polytetrafluoroethylene, hydraulic blockpolytetrafluoroethylene homogeneous glass surface crystallization, can effectively improve the protective layer of the adhesive composition fastness polytetrafluoroethylene PTFE solids dragon in the surface of the glass fiber and formed firmly adhered to the glass fibers of the fiber, thus greatly improving the folded filter, corrosion resistance, wear resistance, strength and other properties. Equipment bag filters, not only broadens the scope of its application, and can greatly extend its service life.hydraulic hose cutting machine
