style="text-indent:25px">脫脂方法不同，對(duì)脫脂劑要求也不同。壓力噴射脫脂因機(jī)械作用力大，脫脂效果好，但由于是處在極易起泡的狀態(tài)下，因而選用低泡脫脂劑是必要的；浸漬脫脂的機(jī)械作用較弱，因此要選用脫脂性能更好的脫脂劑，適當(dāng)?shù)脑黾用撝瑒┖亢脱娱L(zhǎng)脫脂時(shí)間。下道工序是酸洗還是磷化，磷化前有沒(méi)有表面調(diào)整工序，都與堿性金屬脫脂劑的選用有關(guān)。除油脫脂劑廢水的處理方法主要有以下三種，但因可操作性較強(qiáng)大多采用中和法和水稀釋法兩種。中和法。當(dāng)除油脫脂劑廢水量大時(shí)，除去油污后，對(duì)于pH值超標(biāo)的水，應(yīng)用酸中和或?qū)⒑瑝A的廢水當(dāng)作中和含酸廢水的堿液。這樣既可節(jié)省堿液，又可消除含堿廢水。用水稀釋法。當(dāng)廢水量不大時(shí)，可先刮去水面上的油污，再用清水沖?。钩兔撝瑒U水的pH值降至允許排放的標(biāo)準(zhǔn)后再排放。浮力上浮法。此法是利用水的浮力作用由除油脫脂劑廢水中分離懸浮物的方法，本法又分自然浮上法、氣泡浮上法都可用于分離廢水中的油污。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。表面處理脫脂劑生產(chǎn)廠家</p><p style="text-indent:25px">脫脂劑的脫脂溫度: 一般說(shuō)來(lái)，溫度越高，脫脂越徹底。溫度升高，油污粘度降低，容易形成液滴而利于除去。脫脂清洗劑生產(chǎn)廠家</p><p style="text-indent:25px">選用脫脂劑時(shí)應(yīng)注意的事項(xiàng)：根據(jù)被處理零件的材質(zhì)選擇合適的PH值的脫脂劑。根據(jù)油污的種類及數(shù)量選擇合適的脫脂劑。選用脫脂性能好的脫脂劑。注意與下道工序的配合。清洗能力（重量法）。脫脂劑的清洗能力是清洗劑的重要性能，目前檢驗(yàn)脫脂劑的清洗能力的方法有多種，包括定性的檢測(cè)有驗(yàn)油試紙法GB/T13312-91，鋼帶試件涂裝前除油程度檢驗(yàn)方法（驗(yàn)油試紙法），脫脂棉擦拭法，水膜法等。定量檢測(cè)法包括重量法，熒光法，其中重量法是比較方便和比較簡(jiǎn)單的方法。脫脂清洗劑生產(chǎn)廠家</p></p><br
