半水基清(qing)洗采用的清(qing)洗流程如下:
半(ban)水(shui)(shui)基清洗劑(ji)（超聲(sheng)波）-市(shi)水(shui)(shui)漂(piao)(piao)(piao)洗-水(shui)(shui)基清洗劑(ji)-市(shi)水(shui)(shui)漂(piao)(piao)(piao)洗-純水(shui)(shui)漂(piao)(piao)(piao)洗-IPA脫水(shui)(shui)-IPA慢(man)拉(la)干燥
此(ci)種清(qing)(qing)(qing)洗(xi)(xi)(xi)工藝同(tong)溶劑(ji)清(qing)(qing)(qing)洗(xi)(xi)(xi)相比zui大的(de)區別在(zai)于，其(qi)(qi)前兩個清(qing)(qing)(qing)洗(xi)(xi)(xi)單元(yuan)：有(you)(you)機(ji)(ji)(ji)溶劑(ji)清(qing)(qing)(qing)洗(xi)(xi)(xi)只對(dui)瀝青或漆(qi)片(pian)具有(you)(you)良好的(de)清(qing)(qing)(qing)洗(xi)(xi)(xi)效果，但(dan)卻(que)無(wu)法清(qing)(qing)(qing)洗(xi)(xi)(xi)研(yan)(yan)磨粉等(deng)無(wu)機(ji)(ji)(ji)物；半(ban)水(shui)(shui)基(ji)清(qing)(qing)(qing)洗(xi)(xi)(xi)劑(ji)則不同(tong)，不但(dan)可以清(qing)(qing)(qing)洗(xi)(xi)(xi)瀝青等(deng)有(you)(you)機(ji)(ji)(ji)污染物，還對(dui)研(yan)(yan)磨粉等(deng)無(wu)機(ji)(ji)(ji)物有(you)(you)良好的(de)清(qing)(qing)(qing)洗(xi)(xi)(xi)效果，從而(er)大大減輕了后續清(qing)(qing)(qing)洗(xi)(xi)(xi)單元(yuan)中水(shui)(shui)基(ji)清(qing)(qing)(qing)洗(xi)(xi)(xi)劑(ji)的(de)清(qing)(qing)(qing)洗(xi)(xi)(xi)壓力。半(ban)水(shui)(shui)基(ji)清(qing)(qing)(qing)洗(xi)(xi)(xi)劑(ji)的(de)特點是揮發速度很慢，氣(qi)味小。采用(yong)半(ban)水(shui)(shui)基(ji)清(qing)(qing)(qing)洗(xi)(xi)(xi)劑(ji)清(qing)(qing)(qing)洗(xi)(xi)(xi)的(de)設備在(zai)*個清(qing)(qing)(qing)洗(xi)(xi)(xi)單元(yuan)中無(wu)需密封冷凝(ning)和蒸餾回收裝置。但(dan)由于半(ban)水(shui)(shui)基(ji)清(qing)(qing)(qing)洗(xi)(xi)(xi)劑(ji)粘度較大，并(bing)且對(dui)后續工序使(shi)用(yong)的(de)水(shui)(shui)基(ji)清(qing)(qing)(qing)洗(xi)(xi)(xi)劑(ji)有(you)(you)乳化作(zuo)用(yong)，所以第二(er)個單元(yuan)須市水(shui)(shui)漂洗(xi)(xi)(xi)，并(bing)且將其(qi)(qi)設為流水(shui)(shui)漂洗(xi)(xi)(xi)。
國(guo)內應用此種工(gong)藝的企業不多，其中一個原因是(shi)半水基清洗(xi)劑多為進口，價格比較昂貴(gui)。
從(cong)水基清洗單(dan)元開始，半水基清洗工(gong)藝(yi)(yi)同(tong)溶劑清洗工(gong)藝(yi)(yi)基本(ben)相同(tong)。
