style="text-indent:25px">金屬在進(jìn)行化學(xué)處理、電鍍或涂敷之前，要用脫脂劑脫除金屬表面上的油脂及礦物油。脫脂劑是由堿、螯合劑及表面活性劑組成。脫脂劑未使用前，脫脂劑中不含有鐵元素的；用脫脂劑清洗鍍錫基板表面油污、鐵粉雜質(zhì)后，伴隨著脫脂劑中殘鐵含量的逐漸增加，脫脂劑中清洗、脫脂能力逐漸減弱。對于脫脂劑中殘鐵含量檢測，現(xiàn)有技術(shù)中通常用化學(xué)手工方法分析，因基體復(fù)雜要加入各種掩蔽劑進(jìn)行處理，步驟繁瑣，不易掌握，分析結(jié)果準(zhǔn)確性差，且檢測周期較長，不利于現(xiàn)場快速監(jiān)控分析。良好的脫脂劑都是經(jīng)過大量試驗(yàn)，對其組分相互搭配比例進(jìn)行反復(fù)篩選而確定的。鹽城脫脂劑公司</p><p style="text-indent:25px">脫脂除油的對象也很多，有各種金屬材料各不同，有由各種金屬制造的大小不同、形狀復(fù)雜程度不同的零部件。鹽城脫脂劑公司</p><p style="text-indent:25px">在電鍍加工過程中，應(yīng)用比較多的還是水基脫脂劑。它是由堿金屬的氫氧化物、碳酸鹽、磷酸鹽、硅酸鹽和表面活性劑組成。主要用于化學(xué)脫脂，也少量用于電解脫脂和超聲波脫脂。皂化脫脂，金屬表面的油污和脫脂劑中的堿性物質(zhì)發(fā)生皂化反應(yīng)，較終將油脂變成能溶于水的脂肪酸鹽，以達(dá)到脫脂的目的。這類脫脂劑對油脂有一定的選擇性。例如動物油和植物油都可發(fā)生皂化反應(yīng)。但對于礦物油，這種脫脂劑卻無能為力。這就需要第二類脫脂劑一乳化脫脂劑。鹽城脫脂劑公司</p></p><br
