Abstract:
To research the influence of treatment on the dust cleaning performance of filters,polyphenylene sulfide (PPS) filters which are not treated, songed, dipped with polytetrafluoroethy-lene (PTEF) emulsion and laminated with PTEF micro-porous film, respectively, were chosen as the experimental samples. Their filtering effects with different surface morphologies were studied by the dynamic filter performance tester, the surface morphologies of filters before and after filtration were observed by the scanning electron micrsscope. The results showed that laminated filter suffered from a long time filtration and cleaning, and it remained the lowest residual pressure and the longest cleaning cycle time, and had the nost outstanding dust-cleaning performance. The performance of non-treated PPS filter was the second. The filter surface dipped with PTFE emulsion solid substance bas poor performance. The singed filter surface was covered with large area of code-like substance, and its performance was the worst.
Key words: polyphenlene sulfide filter, filter post-treatment, dust filtering, dust-cleaning performance
