style="text-indent:25px">由于油污、油脂的來(lái)源廣、種類(lèi)多，油脂的強(qiáng)度各有不同，所以脫脂問(wèn)題很復(fù)雜。另外脫脂除油的對(duì)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，也有整體機(jī)器及設(shè)備等，這說(shuō)明脫脂除油的工作復(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)。因此，必須給予足夠的重視。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；因此應(yīng)在此幾方面加以足夠重視。哪些因素將對(duì)堿性除油脫脂劑的脫脂效果產(chǎn)生影響和機(jī)械作用和不銹鋼脫脂劑質(zhì)量對(duì)脫脂效果產(chǎn)生的影響兩篇文章詳細(xì)介紹了四大因素將對(duì)脫脂質(zhì)量好壞的影響。義烏脫脂液配方選用脫脂劑時(shí)應(yīng)注意的事項(xiàng)：根據(jù)被處理零件的材質(zhì)選擇合適的PH值的脫脂劑。</p><div

style="text-indent:25px">脫脂劑的脫脂時(shí)間在脫脂操作中，必須保證有足夠的脫脂時(shí)間，壓力噴射脫脂時(shí)間一般為1.5~3分鐘，浸漬脫脂為3~5分鐘（視油污的種類(lèi)和多少而定）。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)。在流水線作業(yè)中，往往不允許采用太長(zhǎng)的時(shí)間，因此一般先用噴射予脫脂1分鐘，再用浸漬脫脂3分鐘。在采用某些種類(lèi)表面活性劑的脫脂液中，過(guò)高的溫度會(huì)使表面活性劑析出聚集如同油珠附著在表面上，造成磷化膜發(fā)花不均勻。</p><p

style="text-indent:25px">脫脂劑的性能特征：除蠟速度快，常溫下可快速溶蠟、剝蠟、除蠟；除蠟范圍廣，可除棕櫚蠟、微晶蠟、拋光蠟等各種類(lèi)型蠟質(zhì)；潤(rùn)濕、滲透能力強(qiáng)，能夠?qū)⒖紫吨械念B固蠟垢迅速溶解剝離；優(yōu)異的防銹性能，具有較強(qiáng)的酸中和能力，可用于酸洗后的防銹；質(zhì)量的銅緩蝕性能；產(chǎn)品性能溫和，可生物降解，綠色環(huán)保。脫脂劑適用于清洗劑體系，推薦用于黑色金屬、銅合金清洗劑，建議原液添加量為3%-5%；應(yīng)用于金屬加工液，建議原液添加量為3%-5%；脫脂劑與DX6508、DX129等復(fù)配使用效果更佳，建議原液添加量為5-15%。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)。義烏脫脂液配方</p><p
