Superfine PPS (polyphenylene sulfide) staple fiber and PTFE (polytetrafluoroethylene) fiber are selected for blending on the dust facing surface, which will not shrink under high temperature, will not affect the gap between the filter bag and the bag cage and ensure the dust filtration performance.
The filter material coated with the high temperature permeable membrane has small pore size and high porosity which can improve the filtration accuracy of the filter material. The primary dust layer is relatively thin, which is easier to remove dust, and the dust stripping rate is high.
PTFE (polytetrafluoroethylene) will form a dense protective film on the fiber surface, which improves the oxidation resistance and corrosion resistance of the filter material. Besides it also has good water and oil repellency and anti-condensation function.
The upper and lower pieces of the stitches on the filter bag are flat and free of folds. The bag mouth and the interface at the bottom of the bag are folded evenly so there will be no gap after being installed on the tubeplate.
