style="text-indent:25px">脫脂劑影響涂膜質(zhì)量，如果脫脂不徹底，雖然磷化膜形成了，但磷化膜不均勻。有些臟物雖然被磷化膜覆蓋，但磷化膜與工件表面的結(jié)合力差，易導致涂膜起泡、脫落。在選擇脫脂方法和脫脂劑時，首先要了解金屬表面所帶的油污的性質(zhì)和組成，只有這樣，才能進行正確的選擇，達到滿意去油效果。油污的組成礦物油、凡士林，他們是防銹油、防銹脂、潤滑油、潤滑脂及乳化液的主要成分。皂類動植物油脂、脂肪酸等，他們是拉延油的主要成分。防銹添加劑，他們是防銹油和防銹脂的主要成分。紹興表面處理除油劑在電鍍加工過程中，應(yīng)用比較多的還是水基脫脂劑。</p><div

style="text-indent:25px">不同的金屬在堿液中有不同的腐蝕界限，必須根據(jù)零件的材質(zhì)選擇合適的pH值的脫脂劑。要考慮零件上的油污的化學性質(zhì)（儲存時能否與周圍介質(zhì)發(fā)生反應(yīng)而脫脂，與脫脂液能否發(fā)生皂化反應(yīng)），油污的物態(tài)（固體或液體，油污中固態(tài)塵顆粒含量），油污對底材的吸附性（分子極性）等情況，再選用合適的脫脂劑。脫脂方法不同，對脫脂劑要求也不同。壓力噴射脫脂因機械作用力，脫脂效果好，但由于處于極易起泡的狀態(tài)下，因此選用低泡脫脂劑是必要的，浸漬脫脂的機械作用較弱，因此要選用脫脂性更好的脫脂劑，適當?shù)脑黾用撝瑒┖亢脱娱L脫脂時間。</p><p style="text-indent:25px">超聲波脫脂是利用超聲波的空化作用、直進流作用、加速度的原理與超聲波脫脂劑的乳化和皂化作用的完美結(jié)合，以達到對清洗工件表面油脂的分離，從而達到物件詳細潔凈的清洗效果，超聲波脫脂特別對深孔、盲孔、凹凸槽清洗效果非常好，且不影響工件的材質(zhì)及精度。各種超聲波清洗機規(guī)格不同價格也不等，因此采用超聲波脫脂會增加設(shè)備購置成本。電解脫脂是將金屬工件作為一個電極，浸在已增加電解脫脂劑的電解液中，通入直流電時，由于極化作用，金屬-溶液界面的界面張力降低，溶液很容易滲透到油膜下的工件表面，發(fā)生還原或氧化反應(yīng)，析出大量的氫氣和氧氣。它們脫離金屬表面浮出，產(chǎn)生強烈的攪拌作用，猛烈地沖擊和撕裂油膜，使吸附在工件上的油膜被碎成細小的油珠，迅速與工件脫離，進入溶液后成為乳濁液，從而達到脫脂的目的。除油脫脂劑的組成和使用方法對脫脂效果有很大的影響。</p><div

style="text-indent:25px">除油脫脂劑由多種表面活性劑及有機助劑復(fù)配而成，是新一代水溶性生物降解的油污清洗劑。本產(chǎn)品具有優(yōu)良的滲透性、乳化性和去除油垢及油焦的能力，在水中有極好的溶解性，使用簡單方便，使用后可以直接排放，適用于各種工件加工過程中產(chǎn)生的拋光蠟、沖壓油、碎屑等物質(zhì)的徹底清洗。超聲波**清洗劑在產(chǎn)品性質(zhì)上具有極強的滲透、分散、增溶、乳化作用，對油脂、污垢有很好的清洗能力，其脫脂、去污凈洗能力很強。本產(chǎn)品不含無機離子，抗靜電，易漂洗，無殘留或極少殘留，可做到低泡清洗，能改善勞動條件，防止環(huán)境污染；并且在清洗的同時能有效地保護被清洗材料表面不受侵蝕，效果非常明顯，性價比高。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)量嚴格，甚至要達到行業(yè)規(guī)定的標準。鹽城化學脫脂劑</p><p
