一般的滌綸針刺氈的連續(xù)工作溫度只能達(dá)到130℃，若工作溫度超過130℃長時間運(yùn)行，則其強(qiáng)力就會失去很多，而且產(chǎn)生很大的收縮，使濾袋的尺寸發(fā)生變化，進(jìn)而影響過濾效果。我公司采用特殊工藝生產(chǎn)的中溫針刺氈，是用玻璃纖維機(jī)織布作基布，在配以優(yōu)質(zhì)滌綸，PPS,亞克力短纖作層面，使其具有斷裂強(qiáng)力高，斷裂伸長小，熱收縮率小，耐溫適中等特點(diǎn)，滿足了工作溫度要求在150℃-170℃。常溫濾料不能滿足而采用高溫濾料又太浪費(fèi)的需要，可在很大程度上降低運(yùn)行成本。按照工況條件的不同要求，我哦那公司對中溫針刺氈做各種功能處理，如拒水防油，PTFE浸漬，涂層，覆膜等。
Polyester needle felt usually  work under 130 ℃。 When working temperature more than 130 ℃  the felt will loss more strength and have a big shrink that size will be changed. So that the filtration efficiency will be discounted. We apply special technology to develop anti-medium temperature needle  felt. Glass fiber weave as basic scrim, then mix excellent polyester, PPS or acrylic short fiber as bedding. Apply medium temperature needle felt can reduce operation cost because it is a bridge between normal temperature material and high temperature material that avoid waste and lack. Finish treatment can be made according to special working conditions such as water and oil proof, PTFE immersion, coating ,membrane and others.
