半水基清洗(xi)采用的清洗(xi)流程如下:
半水(shui)(shui)基清洗(xi)(xi)劑（超(chao)聲波(bo)）-市(shi)水(shui)(shui)漂(piao)洗(xi)(xi)-水(shui)(shui)基清洗(xi)(xi)劑-市(shi)水(shui)(shui)漂(piao)洗(xi)(xi)-純水(shui)(shui)漂(piao)洗(xi)(xi)-IPA脫水(shui)(shui)-IPA慢拉干燥
此種清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)工藝同(tong)溶劑(ji)(ji)(ji)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)相比(bi)zui大的區別在(zai)于，其前兩個清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)單元(yuan)(yuan)：有機(ji)溶劑(ji)(ji)(ji)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)只對(dui)瀝青或漆片具有良好的清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)效果，但卻無(wu)法(fa)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)研磨(mo)粉等無(wu)機(ji)物；半水(shui)基(ji)(ji)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑(ji)(ji)(ji)則不(bu)同(tong)，不(bu)但可(ke)以清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)瀝青等有機(ji)污(wu)染物，還對(dui)研磨(mo)粉等無(wu)機(ji)物有良好的清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)效果，從而(er)大大減輕了后(hou)續清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)單元(yuan)(yuan)中水(shui)基(ji)(ji)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑(ji)(ji)(ji)的清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)壓力。半水(shui)基(ji)(ji)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑(ji)(ji)(ji)的特點是揮發速度(du)很慢(man)，氣味小。采用半水(shui)基(ji)(ji)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑(ji)(ji)(ji)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)的設(she)備在(zai)*個清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)單元(yuan)(yuan)中無(wu)需密(mi)封(feng)冷凝和(he)蒸(zheng)餾回收(shou)裝置(zhi)。但由于半水(shui)基(ji)(ji)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑(ji)(ji)(ji)粘度(du)較大，并(bing)(bing)且(qie)對(dui)后(hou)續工序使用的水(shui)基(ji)(ji)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑(ji)(ji)(ji)有乳化作用，所以第二(er)個單元(yuan)(yuan)須市(shi)水(shui)漂(piao)洗(xi)(xi)(xi)(xi)，并(bing)(bing)且(qie)將其設(she)為流水(shui)漂(piao)洗(xi)(xi)(xi)(xi)。
國(guo)內應用此種(zhong)工藝的企(qi)業(ye)不多，其中一個原因是半水(shui)基(ji)清洗劑多為進(jin)口，價格比較昂(ang)貴。
從水(shui)基清洗單(dan)元開始，半水(shui)基清洗工藝(yi)同(tong)溶(rong)劑清洗工藝(yi)基本相同(tong)。
