style="text-indent:25px">除油脫脂劑所需要清洗的油污有皂化油類和非皂化油類；皂化油類油脂能與堿起化學(xué)作用生成可以溶解于水的脂肪酸鹽和甘油，（拉伸油、切削油、沖壓油、防銹油、潤滑油）等都屬于此類油脂統(tǒng)稱為皂化油；所以清洗皂化油應(yīng)采用水溶性堿性除油脫脂劑。各種礦物油(汽油、煤油、機(jī)油、凡士林等)均是非皂化油。此類油不能與堿起化學(xué)反應(yīng)，其組成和性質(zhì)也與皂化油不同。所以清洗非皂化類油脂應(yīng)選用溶劑除油脫脂劑。堿性化學(xué)脫脂劑是由堿以及表面活性劑等物質(zhì)構(gòu)成，其是利用堿性化學(xué)脫脂劑的皂化和乳化作用、浸透潤濕作用機(jī)理除去可皂化油脂（動(dòng)植物油）和非皂化油脂（礦物油）等金屬表面油脂，可采用噴淋法、電解法，浸泡法、超聲波等脫脂除油工藝。余姚酸性脫脂劑脫脂方法不同，對(duì)脫脂劑要求也不同。</p><div

style="text-indent:25px">脫脂劑的組成和使用方法對(duì)脫脂效果有很大的影響。為了提高油污的乳化和分散能力，適當(dāng)提高脫脂劑中表面活性劑的含量是有效的，不同的表面活性劑品種及不同的堿性物的脫脂效果有一定的差異。良好的脫脂劑都是經(jīng)過大量試驗(yàn)，對(duì)其組分相互搭配比例進(jìn)行反復(fù)篩選而確定的。隨著使用過程中脫脂劑的消耗，有必要定期加以補(bǔ)充，以保持必要的濃度。在脫脂中，借助于壓力噴射或攪拌等機(jī)械作用是非常有效的，因?yàn)閲娚鋾r(shí)迫使新鮮的脫脂溶液與零件表面有良好接觸，使整個(gè)脫脂液含量均勻，有利于提高脫脂效果；噴射時(shí)依靠機(jī)械作用力促使脫脂劑滲透和破壞油膜，從而有效迫使油污脫離零件表面。</p><p style="text-indent:25px">金屬脫脂劑主要用于脫除金屬材料表面的油污、油脂類。其中一類是以脂肪酸甘油脂為主的植物油、動(dòng)物油、食用油等皂化油,可通過與金屬脫脂劑中堿的皂化作用去除。另一類是以各種潤滑油、機(jī)械油、礦物油、離合油、齒輪油、剎車油、機(jī)油、油墨、脫模油、壓縮機(jī)油，冷凍機(jī)油，真空泵油、內(nèi)燃機(jī)油等礦物油(非皂化油),可通過金屬脫脂劑的乳化作用來脫除。在金屬材料表面處理中,脫脂是重要的工藝過程，金屬制件表面的脫脂程度將直接影響到制件的后續(xù)處理質(zhì)量。據(jù)統(tǒng)計(jì)，在表面處理中由于金屬脫脂劑的脫脂不徹底而導(dǎo)致鍍層、轉(zhuǎn)化膜不良的比例,一般占60%～80%。所以選用一款好的金屬脫脂劑對(duì)于整個(gè)表面處理工藝至關(guān)重要。脫脂劑的某些油污如含有不飽和脂肪酸的拉延油，長期存放后，氧化聚集形成薄膜，含有固體粉料的拉延油。</p><div
