  KY®-12(PPS濾袋)應用于煤電等工況

 

 

  聚苯硫醚是一種耐高溫合成纖維。它良好的耐溫性和化學穩定性是由它簡單的化學結構決定的,具有耐熱性,耐化學性,阻燃性等諸多特性。它的PH1-14是完全耐酸堿型纖維、尺寸穩定性能極佳,具備高性能合成纖維的各種特點。它的連續工作溫度可達190℃,瞬間220℃。它能抵抗許多酸、堿和氧化劑的化學腐蝕。最重要的是PPS不會水解,在電廠應用上,它只要求煤氣中的含水量在3.5%,含硫量在2700mg/m3以下。

  缺點是抗氧化性能差,要求NOx含量小于600mg/Nm3;O2含量小于10%,含氧量越高,所使用的溫度就要越低。因每增加10℃,化學反應成雙倍增加,也就是說,原來壽命三年,若溫度增加10℃,其壽命會只有1.5年。
