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。在采用某些種類表面活性劑的脫脂液中，過高的溫度會(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。除油脫脂劑的組成和使用方法對(duì)脫脂效果有很大的影響。</p><div
