style="text-indent:25px">除油脫脂劑對(duì)脫脂效果的影響：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。例如，含有表面活性劑的堿性除油脫脂劑比單獨(dú)的堿性溶液脫脂效果好。對(duì)于滴落點(diǎn)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(dāng)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(chǎn)生一定差異，良好的除油脫脂劑都是經(jīng)過(guò)大量試驗(yàn)，對(duì)其成分相互搭配比例進(jìn)行反復(fù)篩選而確定的。對(duì)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(guò)程中，除油脫脂劑會(huì)不斷的被消耗，使?jié)舛冉档?，因此，必須定期的補(bǔ)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(guān)系，因此對(duì)于脫脂質(zhì)量要求很高的情況，不應(yīng)當(dāng)采取大幅度提高濃度的方法，而應(yīng)該采用二次脫脂的辦法，倆個(gè)脫脂液可以是相同的，而且不必額外的提高濃度。對(duì)于脫脂除必須給予足夠的重視。無(wú)錫脫脂劑的價(jià)格</p><p
