style="text-indent:25px">酸性脫脂劑主要由無機(jī)酸、氧化劑、高價(jià)金屬離子及表面活性劑等成分組成。其中，無機(jī)酸可以是H2SO4、HO4、HF、亞磷酸、硼酸等。H2SO4對(duì)鋁合金有弱浸蝕能力，能潤(rùn)濕整個(gè)金屬表面，使自然氧化膜溶解，油污松動(dòng)。高價(jià)金屬離子一般選用Fe,一般以硫酸鐵、硝酸鐵等鐵鹽形式加入，以加速鋁的腐蝕，鐵離子可以在鋁表面發(fā)生置換反應(yīng)，形成微電池，使鋁表面產(chǎn)生微量氫氣，將油污帶出鋁表面；同時(shí)，鐵離子還可以阻止它脫脂液對(duì)不銹鋼設(shè)備的腐蝕。氧化劑主要是H2O2或NO(如NaNO2)等，作為Fe的穩(wěn)定劑，將還原產(chǎn)生的二價(jià)鐵離子氧化成為三階鐵離子，并起到Fe類似的功能。山東電鍍鎳添加劑企業(yè)化學(xué)鍍鎳藥劑鍍層中不含有任何有毒重金屬，因此鍍層環(huán)保無毒,完全符合RoHS指令標(biāo)準(zhǔn)。</p><div

style="text-indent:25px">鎂合金表面處理方法：等離子微弧陽極氧化是陽極氧化技術(shù)的發(fā)展，它使用比普通陽極氧化高的電壓。微弧氧化是將Al、Ti、Ta等金屬或其合金置于電解質(zhì)水溶液中，利用電化學(xué)方法，使該材料表面微孔中產(chǎn)生火花放電斑點(diǎn)，在熱化學(xué)、等離子體化學(xué)和電化學(xué)共同作用下，生成陶瓷膜層的陽極氧化方法。等離子微弧陽極氧化在陽極區(qū)產(chǎn)生等離子微弧放電，火花存在時(shí)間為1-2s，火花放電使陽極表面局部溫度升高，使微區(qū)溫度高于1000℃。從而使陽極氧化物熔覆在金屬表面，形成陶瓷質(zhì)的陽極氧化膜，提高了陽極氧化膜的硬度和致密性?；鸹óa(chǎn)生的原因是由于外加電壓大于已沉積層的擊穿電壓。氧化膜厚度隨電流密度和處理時(shí)間增加而增厚，一般膜厚度在2.5-30um。等離子體微弧陽極氧化膜的耐蝕性與抗磨性比普通陽極氧化膜高。山東電鍍鎳添加劑企業(yè)</p><p
