style="text-indent:25px">金屬電鍍前后處理劑的堿性清洗劑的主要有氫氧化鈉、碳酸鈉、硅酸鈉、磷酸鈉等，溶于水成為堿性清洗劑。它們的作用原理是能和油污中的脂肪酸甘油酯發(fā)生皂化作用形成初生皂，使油污成為水溶性的而被溶解去除。其中氫氧化鈉和碳酸鈉還有中和酸性污垢的作用。磷酸鈉、三聚磷酸鈉、六偏磷酸鈉等既具有清洗作用，又有控制腐蝕的作用。硅酸鈉則有膠溶、分散等作用，清洗效果較好。堿性清洗劑由于價(jià)格較低、沒有毒性、不易燃等原因，使用較為普遍。但在使用堿性清洗劑時(shí)要注意被清洗金屬的材質(zhì)，選擇適當(dāng)?shù)膒H的堿液。此外，在使用堿性清洗劑時(shí)，通常加入表面活性劑構(gòu)成復(fù)合配方，以加強(qiáng)清洗作用。上海前處理劑</p></p><br
