不銹鋼燒結濾芯破損應該采取怎樣的措施?

時間:2019-06-15來源:www.5139sss.com

  不銹鋼燒結濾芯破損應該采取怎樣的措施?

  由于濾芯破損的主要原因是濾芯在再生過程中發生了滲碳,而滲碳是在高溫下才會發生,所以解決的根本辦法是防止濾芯再生過程中進行焙燒。

不銹鋼燒結濾芯

  不需要高溫焙燒過程的不銹鋼燒結濾芯再生的工藝如下:

  1、去油。根據油漿的成分和特征,采用經過篩選的清潔劑對粘附的濾芯表面的油漿進行軟化、溶解和清洗,將油漿清洗干凈。

  2、堿洗。用強堿溶解濾芯內的催化劑顆粒。

  3、高壓水沖洗。用高壓水對經過堿洗后的濾芯進行沖洗。

  4、酸洗。進一步清除濾芯內的金屬氧化物等雜質。

  5、透水性檢驗。在一定的水流流量下,對清洗后的濾芯壓降進行測量,若沒有超出設定值則合格,否則就需要從新清洗過程,直到合格為止。

  6、鼓泡實驗。將處理好的濾芯用多孔材料性能測控儀測試其鼓泡點。若濾芯過濾精度等級值高于初泡點低于濾芯過濾精度等級值視為不合格濾芯,對漏點采用等離子焊接進行焊補。補焊后,再次進行鼓泡試驗,直到合格為止。
