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)?，噴射時(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，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。由于油污，鎮(zhèn)江脫脂劑供應(yīng)商、油脂的來源廣，鎮(zhèn)江脫脂劑供應(yīng)商、種類多，鎮(zhèn)江脫脂劑供應(yīng)商，油脂的強(qiáng)度各有不同，所以脫脂問題很復(fù)雜。鎮(zhèn)江脫脂劑供應(yīng)商</p><div

style="text-indent:25px">脫脂劑的性能檢測還有硬水穩(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：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。第二類是水基脫脂劑，采用無機(jī)堿、鹽與表面活性劑組成。這類脫脂劑是電鍍脫脂劑的主體。第三類是無機(jī)和有機(jī)物的混合脫脂劑，又稱乳化液脫脂。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。除油劑生產(chǎn)商乳液脫脂劑，利用表面活性劑的潤濕性、浸透性、乳化性及分散性可以脫除金屬表面的污垢。</p><div

style="text-indent:25px">金屬脫脂除油是機(jī)械涂裝行業(yè)前處理工藝中較關(guān)鍵的工序之一。金屬表面脫脂的程度將直接影響磷化序和涂裝質(zhì)量。它利用高效液體脫脂劑對(duì)油脂和污物的皂化、潤濕、乳化、滲透、卷離、分散和增溶等作用把工件表面的各種油脂、灰塵泥沙、金屬粉末手汗及其工件在加工過程中所粘附的油性臟物高效的去除脫離徹底。隨著環(huán)保要求的提高，目前比較流行研究應(yīng)用生物可降解表面活性劑，對(duì)于活性劑，清洗劑要求無磷、無硅和低COD/BOD排放。雖然此方面的研究工作已開展30多年，但是目前還沒有一種無磷助劑能夠同時(shí)保證去污能力、對(duì)人體和環(huán)境無危害和潛在危害、成本較低這3項(xiàng)要求。現(xiàn)在已研究出無磷脫脂劑，但成本高，應(yīng)用還有一定的阻力。</p><p style="text-indent:25px">脫脂劑也就是用于脫離溶解去除各類油脂用的工業(yè)清洗劑。油脂分為皂化類油脂和非皂化類油脂；皂化類油脂有拉伸油、切削油、沖壓油、防銹油、潤滑油等；非皂化類油脂有汽油、煤油、機(jī)油等各種礦物油。皂化類油脂通過水基脫脂劑的乳化皂化作用就可以將油脂脫離去除，如裕滿實(shí)業(yè)水基脫脂劑WP-751；而非皂化類油脂與水是不相溶的，得通過溶劑脫脂劑溶解功能去除脫離，如三氯乙烯替代品脫脂劑FRB-1.1、環(huán)保碳?xì)淝逑磩┟撝瑒〧RB-101等。所以在選用脫脂劑時(shí)應(yīng)首先知道所要去除油脂的類別，然后再根據(jù)其它因素來選用具有針對(duì)性的脫脂劑。脫脂除油的工作復(fù)雜，影響面廣，在許多情況下要求清洗質(zhì)量嚴(yán)格，甚至要達(dá)到行業(yè)規(guī)定的標(biāo)準(zhǔn)。</p><div

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(duì)油脂有一定的選擇性。例如動(dòng)物油和植物油都可發(fā)生皂化反應(yīng)。但對(duì)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。對(duì)于脫脂除必須給予足夠的重視。鎮(zhèn)江脫脂劑供應(yīng)商</p><p style="text-indent:25px">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。鎮(zhèn)江脫脂劑供應(yīng)商</p><p style="text-indent:25px">堿脫脂劑。由堿、螯合劑、表面活性劑及緩蝕劑所組成。堿可使油脂皂化而乳化分散，使礦物油分散。所用的堿可為氫氧化鈉、重碳酸鈉、倍半碳酸鈉、碳酸鈉、磷酸鈉、焦磷酸鈉以及三聚磷酸鈉等。這些堿對(duì)油分和金屬的作用各不相同，一般需要2～3種配合使用。螯合劑系由金屬離子和螯合物所制成，它可使金屬皂溶解，使硬水軟化，對(duì)堿和表面活性劑起著促進(jìn)乳化分散的作用，并可防止非溶解性物質(zhì)附著在金屬表面上。所用表面活性劑以非離子型為佳，表面活性劑可以使金屬表面的污垢脫離，而被除去，脫除的方法可以采用噴淋或浸漬。緩蝕劑主要是防止堿及其他化學(xué)藥劑對(duì)金屬的腐蝕。鎮(zhèn)江脫脂劑供應(yīng)商</p></p><br
