style="text-indent:25px">脫脂劑的性能檢測(cè)還有硬水穩(wěn)定性能，高低溫穩(wěn)定性和單片和疊片防銹性能。從脫脂劑的組成上將脫脂劑分為三類(lèi)：一是有機(jī)脫脂劑，如煤油、汽油、三氯乙烯、四氯化碳等脫脂劑，這些脫脂劑只是粗脫脂，不能脫脂后直接龜鍍。第二類(lèi)是水基脫脂劑，采用無(wú)機(jī)堿、鹽與表面活性劑組成。這類(lèi)脫脂劑是電鍍脫脂劑的主體。第三類(lèi)是無(wú)機(jī)和有機(jī)物的混合脫脂劑，又稱(chēng)乳化液脫脂。它是以表面活性劑為主，加入煤油或汽油與水形成乳液，生產(chǎn)上應(yīng)用較少。脫脂質(zhì)量的好壞主要取決于脫脂溫度、脫脂時(shí)間、機(jī)械作用和脫脂劑四個(gè)因素。</p><div

style="text-indent:25px">脫脂劑的的機(jī)械作用在脫脂中，借助于壓力噴射或攪拌等機(jī)械作用是非常有效的，因?yàn)椋瑖娚鋾r(shí)迫使新鮮的脫脂溶液與零件表面有良好的接觸，而且整個(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，從而有效的迫使油污脫離零件表面；噴射時(shí)促使脫離零件的油污乳化和分散于脫脂溶液中，防止油污再吸附到洗凈的零件表面上。在中低溫脫脂中，機(jī)械作用尤為重要。一般的說(shuō)，壓力噴射比浸漬脫脂速度快1倍以上。噴射壓力通常為（0.1~0.2）Mpa(用于壓力噴射的脫脂劑必須是低泡的，以免泡沫過(guò)多影響正常操作和脫脂液流失)，浸漬脫脂也不能認(rèn)為是靜止浸漬，必須裝備循環(huán)泵，使溶液不停的攪動(dòng)，每小時(shí)的循環(huán)量約為槽液體積的5倍。我們選擇脫脂劑前應(yīng)先了解所脫脂脂的種類(lèi)。寧波除油劑</p><p style="text-indent:25px">浸泡脫脂所需設(shè)備簡(jiǎn)單、對(duì)復(fù)雜工件、有空腔結(jié)構(gòu)等的工件脫脂效果好，但脫脂處理時(shí)間相對(duì)較長(zhǎng)。南通表面處理除油劑</p><p style="text-indent:25px">乳化脫脂對(duì)油脂的限制較小，可以使用較低一些溫度，一般在50～70℃即可。而置換脫脂可以使用較低的溫度，一般在10～50℃下使用。但置換脫脂劑對(duì)蠟類(lèi)去除效果不佳，在常溫下不能去除石蠟、凡士林、拋光膏等油脂。但置換脫脂劑對(duì)大多礦物油還是很有效果的。它的較大優(yōu)點(diǎn)不僅是脫脂快，更重要的是節(jié)能。脫脂劑的性能、脫脂原理，但它們卻不是孤立的，是相互聯(lián)系在一起的。舉例來(lái)說(shuō)，水中加入氫氧化鈉、碳酸鈉、磷酸鈉(還可再加入硅酸鈉)就配成了皂化型脫脂劑。當(dāng)這種脫脂劑溫度升至70℃以上使用時(shí)，油脂就和脫脂劑發(fā)生皂化反應(yīng)。在這種脫脂劑中加入表面活性劑，例如：OP-10，將溫度達(dá)到50～70℃之間，這時(shí)的油脂便會(huì)被乳化劑乳化后除去，這時(shí)的脫脂劑就變成了乳化型脫脂劑(第二類(lèi)脫脂劑)。在這種脫脂劑中再加入某些表面活性劑，就可以變成置換型脫脂劑，可以在10～50℃之間使用。南通表面處理除油劑</p><p
