style="text-indent:25px">金屬表面處理的質(zhì)量直接影響涂層對(duì)被涂工件基材的附著力及材料的耐腐蝕性能。所以，要獲得高質(zhì)量的產(chǎn)品，須嚴(yán)格涂裝前的表面處理作業(yè)。通過前處理，使得工件達(dá)到無油污及水分;無銹跡及氧化物;無酸、堿等殘留物;工件表面達(dá)到一定的粗糙度等要求。工件表面處理合格后，經(jīng)干燥除去水分，即可進(jìn)入涂裝。按照工件材質(zhì)不同如銅、鐵、鋁及鋁合金或塑料等，其前處理工藝條件是有不同的。還要將工件表面油污除去，除油的方法有堿性溶液除油、乳化劑除油、溶劑除油及超聲波除油等。水洗也是金屬表面處理的主要輔助工序，在脫脂、磷化后都采用，以清理殘存在工件上的各種溶液的殘?jiān)?，水洗全部與否直接影響工件涂層的質(zhì)量和防腐能力。為節(jié)約能量，此二道水洗可采用逆流漂洗技術(shù)。在磷化后的一道水洗應(yīng)采用去離子水洗以確保磷化質(zhì)量。磷化前的表面調(diào)整處理可除去由于堿性脫脂而造成的表面狀態(tài)不均勻性，經(jīng)磷酸鈦鹽溶液預(yù)處理的零件表面能產(chǎn)生電位，活化表面，從而產(chǎn)生大量的自由能，增加了磷化晶核數(shù)目，使晶粒變得更加微細(xì)，加速成膜反應(yīng)。</p><p style="text-indent:25px">金屬清洗劑是由表面活性劑與添加的清洗助劑（如堿性鹽）、防銹劑、消泡劑、香料等組成。其主要成分表面活性劑有數(shù)種類型，國(guó)產(chǎn)的主要是非離子型表面活性劑，有醚、酯、酰胺、聚醚等4類，具有較強(qiáng)的去污能力。一.注意清洗劑的濃度。清洗劑的濃度與清洗效果有很大的關(guān)系，通常隨著濃度的增加，去污能力也相應(yīng)的增強(qiáng)，但達(dá)到一定濃度后，去污能力不再明顯提高。二.要掌握好清洗劑溫度。通常情況下，隨著清洗劑溫度的升高，其去污能力也隨之提高，但超過一定溫度后，去污能力反而下降。三.掌握清洗劑的使用時(shí)間。一次配制的清洗劑可以多次使用，其使用時(shí)間主要取決于清洗零件的數(shù)量與清洗劑的污染程度，為了節(jié)約清洗劑的用量，提高清洗質(zhì)量，清洗時(shí)應(yīng)按零件特征，合理安排清洗順序。四.注意零件污垢的種類和性質(zhì)。汽車零件污垢的種類和性質(zhì)差異很大，有油泥、水垢、積炭、銹跡等固相油污及潤(rùn)滑油、脂的殘留物等液相油污。五.要考慮清洗條件。若具有蒸汽加熱條件時(shí)，可選用高溫型清洗劑。以手工清洗為主或被清洗零件不宜加熱時(shí)，則選用低溫型清洗劑。采用機(jī)械清洗和壓力噴淋時(shí)，要選用低泡沫的清洗劑。金屬表面處理的作用有哪些？</p><div
