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。太倉(cāng)脫脂劑公司增加脫脂時(shí)間，即延長(zhǎng)脫脂液與油污的接觸時(shí)間，從而提高脫脂效果。油污越多，脫脂時(shí)間就需越長(zhǎng)。</p><div

style="text-indent:25px">脫脂劑的脫脂溫度:一般說(shuō)來(lái)，溫度越高，脫脂越徹底。溫度升高，油污粘度降低，容易形成液滴而利于除去。溫度升高也能促進(jìn)化學(xué)反應(yīng)的進(jìn)行，提高化學(xué)反應(yīng)速度。加速表面活性劑分子的運(yùn)動(dòng)，從而促進(jìn)浸潤(rùn)、乳化、分散等作用。但過(guò)高的溫度會(huì)使表面活性劑析出聚集在表面上，造成磷化膜發(fā)花不均勻。脫脂時(shí)間:在脫脂操作中，必須保證有足夠的脫脂時(shí)間。增加脫脂時(shí)間，即延長(zhǎng)脫脂液與油污的接觸時(shí)間，從而提高脫脂效果。油污越多，脫脂時(shí)間就需越長(zhǎng)。一般壓力噴射脫脂時(shí)間為1.5-3分鐘，浸漬脫脂為3-5分鐘。</p><p style="text-indent:25px">堿性化學(xué)脫脂劑除油機(jī)理:皂化作用：金屬表面油脂中的動(dòng)植物油（主要成分是硬脂酸），與堿性化學(xué)脫脂劑中的堿生成硬脂酸鈉（即肥皂）和甘油溶解進(jìn)入堿性溶液，俗稱皂化反應(yīng)，以除去金屬表面油脂。乳化作用：乳化劑為表面活性物質(zhì)，吸附在界面上，憎水基團(tuán)向著金屬基體，親水基團(tuán)溶液方向，使金屬與溶液間界面張力降低，從而在流體動(dòng)力等因素的作用下，油膜破裂變成細(xì)小的珠狀，脫離金屬表面，到溶液中形成乳濁液。皂化與乳化作用是相輔相成的，相互配合才能徹底去除金屬表面油污。浸透潤(rùn)濕作用：皂化與乳化作用均系從油污表面逐步進(jìn)行，而使含堿性化學(xué)脫脂劑的堿性溶液浸透油脂內(nèi)部，達(dá)到并潤(rùn)濕工件表面，增進(jìn)了脫脂除油的效果，這就是表面活性劑的浸透潤(rùn)濕作用。此外還仍具有分散作用，將從工件除下的油脂分散到脫脂液之中。由于油污、油脂的來(lái)源廣、種類多，油脂的強(qiáng)度各有不同，所以脫脂問(wèn)題很復(fù)雜。</p><div

style="text-indent:25px">在使用脫脂劑時(shí)應(yīng)注意什么問(wèn)題?管道和設(shè)備的脫脂溶劑通常采用四氯化碳或二氯乙烷，二者均具有毒性。因?yàn)槎纫彝檫€有燃燒和的危險(xiǎn)，所以較常用的溶劑是四氯化碳。四氯化碳對(duì)人體是有毒的。它是脂肪的溶劑，有強(qiáng)有力的麻醉作用，且易被皮膚吸收。四氯化碳中毒能引起頭疼、昏迷、嘔吐等癥狀。四氯化碳在500℃以下是穩(wěn)定的。在接觸到煙火，溫度升至500℃以上時(shí)，四氯化碳蒸氣與水蒸氣化合可生成光氣。在常溫下四氯化碳與硫酸作用也能生成光氣。光氣是劇毒氣體，極其微量也能引起中毒。此外，四氯化碳與堿發(fā)生化學(xué)反應(yīng)，會(huì)生成甲烷而失效。使用過(guò)程中，脫脂劑會(huì)不斷的被消耗，使?jié)舛冉档?，因此，必須定期的補(bǔ)加脫脂劑，以保持必要的濃度。鎮(zhèn)江脫脂劑公司</p><p
