style="text-indent:25px">我們知道陶化工藝主要常用于鐵及鋼鐵做中做涂裝打底防腐處理，而金屬鋅常用的工藝一般是傳統(tǒng)的磷化技術(shù)。但隨著新時(shí)代人們對(duì)于環(huán)保的日趨重視，環(huán)保型陶化技術(shù)到底能不能取代磷化，廣應(yīng)用于金屬鋅及合金呢?陶化劑是一種無磷酸鹽的反應(yīng)型金屬前處理化學(xué)品，具有穩(wěn)定性好，無沉渣，不含磷酸鹽。通過陶化處理后可在鋼鐵、鋅和鋁的表面上形成一層納米級(jí)陶瓷轉(zhuǎn)化膜，特別適合于鋼鐵、鋅和鋁表面處理。能增強(qiáng)涂裝的結(jié)合力和耐腐蝕性能，適合常溫的噴淋和浸泡處理，處理后可用去離子水洗;能和各種型號(hào)的涂料匹配，無須加熱設(shè)備，處理時(shí)間短，操作簡單，有效達(dá)到節(jié)約能源、易于生產(chǎn)的作用。</p><p style="text-indent:25px">除油劑的組成根據(jù)油脂的種類和性質(zhì)，除油劑包含兩種主體成分，堿類助洗劑和表面活性劑。堿類助洗劑常用的為氫氧化鈉、純堿、硅酸鈉和三聚磷酸鈉。氫氧化鈉和純堿作為堿劑，價(jià)格比較為便宜，廢水較難處理，有時(shí)由于堿性偏強(qiáng)導(dǎo)致清洗物體受到損傷，還有一方面氫氧化鈉和純堿沒有乳化作用對(duì)于礦物油清洗沒有任何效果;硅酸鈉與三聚磷酸鈉既能提供堿性，又能提供一定的乳化力，廣用于各種除油清洗劑中特別是對(duì)堿敏感的除油工藝。使用硅酸鈉比較大的是除油后若不用熱水先洗一道，直接冷水洗很難將殘留的硅酸鈉完全洗凈，殘留的硅酸鈉會(huì)與下一道工序的酸反應(yīng)生成附著牢固的硅膠，從而影響鍍層的結(jié)合力;三聚磷酸鈉則主要存在磷污染破壞環(huán)境的擔(dān)憂。陶化劑工藝原理，你知多少？</p><div

style="text-indent:25px">金屬除油劑是指用于金屬表面以去除油污、油脂、污漬為目的用的化學(xué)藥劑，除油是金屬零件電鍍、涂裝前以及金屬加工成型中的關(guān)鍵工序，那歸根結(jié)底，金屬除油劑能帶來什么作用呢？一、皂化作用，指苛性鈉和堿性強(qiáng)的鹽類與油脂反應(yīng)生成肥皂和甘油后溶于水而除去油脂的作用。皂化作用只能去掉動(dòng)、植物油脂。二、乳化作用，指將油脂變成微小的液滴散布在溶液中，成為乳濁液而除去油污的作用。礦物油物油等非皂化油，只有通過乳化作用才能除去。三、潤滑作用，指溶液滲入油脂中，并在金屬表面擴(kuò)散以減少油脂對(duì)金屬表面的附著力．使之脫落。各種表面活性劑都具有良好的潤滑作用。四、分散作用，指將油脂從金屬表面脫落之后，分散進(jìn)入到溶液中的作用。除表面活性劑外，硅酸鈉、磷酸鈉等也有較好的分散作用。五、溶解作用，利用有機(jī)溶劑對(duì)油脂的溶解作用，把油污除去。金屬表面除油脫脂的常用方法？常州金屬前處理液</p><p style="text-indent:25px">如何選擇質(zhì)量好的金屬清洗劑？常州金屬前處理液</p><p style="text-indent:25px">磷化是金屬材料防腐蝕的重要方法之一,其作用在于給基體金屬提供防腐蝕保護(hù)、用于噴漆前打底、提高覆膜層的附著力與防腐蝕能力及在金屬加工中起減摩潤滑作用等。磷化是常用的前處理技術(shù)，原理上應(yīng)屬于化學(xué)轉(zhuǎn)化膜處理。工程上應(yīng)用主要是鋼鐵件表面磷化，但有色金屬如鋁、鋅件也可應(yīng)用磷化。鋼鐵表面涂裝前處理工藝指脫脂（除油）、除銹、表調(diào)、磷化。然而由于工件表面的狀況不一樣，則生產(chǎn)工藝也有所區(qū)別，有的工藝中沒有脫脂或沒有除銹工序，有的工藝則沒有表面調(diào)整工序，但磷化工序是不可缺少的。常州金屬前處理液</p><p
