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。我們選擇脫脂劑前應(yīng)先了解所脫脂脂的種類。</p><div
