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，脫脂劑開發(fā)，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)，脫脂劑開發(fā)，浸漬脫脂也不能認(rèn)為是靜止浸漬，必須裝備循環(huán)泵，脫脂劑開發(fā)，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。脫脂劑的脫脂溫度一般說來，溫度越高，脫脂越徹底。脫脂劑開發(fā)</p><div

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)藥劑對金屬的腐蝕。</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于整個(gè)表面處理工藝至關(guān)重要。脫脂劑開發(fā)</p></p><br
