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乳化分散的作用，并可防止非溶解性物質附著在金屬表面上。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藥劑對金屬的腐蝕。南通脫脂劑廠家脫脂除油的對象也很多，有各種金屬材料各不同，有由各種金屬制造的大小不同、形狀復雜程度不同的零部件。</p><div

style="text-indent:25px">脫脂劑的消泡性能。消泡性能試驗主要是為了檢查水基脫脂劑溶液的泡沫消除能力。試液按30g/L或說明書規(guī)定配制，并預熱至(30±2)℃，將試液倒入比色量筒中使液面距離塞下端面70mm，蓋塞，在(30±2)℃下恒溫10min取出，立即上下?lián)u動1min，搖動距離為0.33m，頻率約為100次/min。搖動完畢后，打開筒塞，在(30±2)℃溫度下靜置10min后觀察泡沫高度。脫脂劑的的乳化性能。乳化性能測定采用比色量簡裝50mL脫脂劑及規(guī)定數量的4號拉延油，溫度在55℃，以均勻的速度上下?lián)u晃30次，距離為400mm，記錄下工作液的狀態(tài)有無分層現象。</p><p style="text-indent:25px">脫脂劑的機械攪拌。在液體中加以機械攪拌，使固體表面之液膜減薄。攪拌越強，液膜越薄，但其作用有一定限度。擦洗。加溫清洗:增加熱運動。噴洗:用高壓噴洗。蒸氣清洗:用溶劑蒸氣清洗。溶劑在金屬表面上冷凝成液體，液體流淌時帶下污物。超聲波輔助清洗:利用超聲波振蕩作用，使固體表面被沖擊震動，促使污物離開金屬表面。電解清洗:利用金屬表面電化學反應生成氣體。氣體自表面逸出時，使污物析出，自表面剝離。一種用于眼鏡框電鍍前處理水基金屬脫脂劑的研制。脫脂劑按照性狀可分為溶劑型和水基兩種，其中水基脫脂劑可分為酸性，中性，堿性脫脂劑。</p><div

style="text-indent:25px">脫脂劑的某些油污如含有不飽和脂肪酸的拉延油，長期存放后，氧化聚集形成薄膜，含有固體粉料的拉延油。細微的粉料吸附在基體金屬表面上，還有當油污和金屬腐蝕物等混合在一起，都會極大的增加清洗的難度。脫脂是依靠脫脂劑對污物的溶解作用，皂化作用，依靠表面活性劑對污物的潤濕、滲透、分散等物理作用等等。使污物成為可溶解的或可分散的。但還必須使污物離開金屬表面，而讓新的清洗劑占據表面，這樣金屬表面才能達到清潔。因固體表面有相對穩(wěn)定的液膜，溶解后的污物自動離開金屬表面以及表面上清洗劑的更新等都不是很容易的。這就要求加以攪拌、擦拭等方式，以完成清洗過程或提高清洗效果等。脫脂劑的多級水洗。通常進行2道以上水洗(浸漬或噴淋，噴淋更適用帶縫隙工件)，一般認為熱水洗優(yōu)于冷水洗。南通脫脂劑廠家</p><p style="text-indent:25px">脫脂劑按酸堿度分類：酸性脫脂劑是指PH值低于7的脫脂劑。連云港脫脂劑批發(fā)</p><p style="text-indent:25px">除油脫脂劑對脫脂效果的影響：除油脫脂劑的組成和使用方法對脫脂效果有很大的影響。例如，含有表面活性劑的堿性除油脫脂劑比單獨的堿性溶液脫脂效果好。對于滴落點高的固態(tài)或半固態(tài)油脂，用溶劑清洗比用其他脫脂效果有效。為了提高油污的乳化和分散能力，適當提高除油脫脂劑中表面活性劑的含量是有效的，不同的表面活性劑品種及不同的堿性物都使脫脂效果產生一定差異，良好的除油脫脂劑都是經過大量試驗，對其成分相互搭配比例進行反復篩選而確定的。對于含有表面活性劑的堿性除油脫脂劑，較有效的發(fā)揮洗凈作用是在表面活性劑的臨界膠束濃度的上限。使用過程中，除油脫脂劑會不斷的被消耗，使?jié)舛冉档?，因此，必須定期的補加脫脂劑原液，以保持必要的濃度。除油脫脂劑的脫脂效果與濃度并不是直線上升的關系，因此對于脫脂質量要求很高的情況，不應當采取大幅度提高濃度的方法，而應該采用二次脫脂的辦法，倆個脫脂液可以是相同的，而且不必額外的提高濃度。連云港脫脂劑批發(fā)</p></p><br
