在鍍銅的時候?yàn)榱舜_保鍍出的膜純度高一些，因此要在鍍銅工藝中去除雜質(zhì)，尤其是要排除鍍膜溶液中鐵離子污染的情況，這個是十分影響鍍銅純度的?？梢允褂缅冦~稀釋法，根據(jù)鐵離子的含量讓其稀釋后根據(jù)檢測結(jié)果給予溶液補(bǔ)充鉻酐和硫|酸。也可以使用離子交換法，通常會使用強(qiáng)酸陽離子交換樹脂。另外，除了鍍銅稀釋法、離子交換法外，還可以使用鍍銅隔離電解法，把溶液注入陰極室進(jìn)行電解處理，將Cr6+還原成Cr3+，能使得溶液的PH值升高，使得鐵等金屬離子生成氫氧化物沉淀、過濾和去除。這三種方法是常見的用來去除鍍銅溶液里鐵雜質(zhì)的操作方法。 </p><p style="text-indent:25px">電解鍍銅是針對金屬外表進(jìn)行鍍銅加工的，通常是需要與多種化學(xué)反應(yīng)參與的，通過各種極話反應(yīng)達(dá)到鍍銅效果。所謂的電解鍍銅的計劃反應(yīng)是說電流通過電極的時候，電極電位偏離平衡電極電位的現(xiàn)象，這個反應(yīng)是有溶液濃度極化和電化學(xué)極化引起的。濃差極化是指因靠近電極表面的液體層濃度與溶液兩者間的差異而引起的極化，發(fā)生這個現(xiàn)象是由于離子在溶液中的擴(kuò)散小于電子。電化學(xué)極化是指由于陰極上的電化學(xué)反應(yīng)小于外部電源提供的電子的速度，因而電解極電位在負(fù)方向移動引起的極化效應(yīng)。通過添加大量的鹽酸來消除"低電流密度區(qū)鍍層不光亮"現(xiàn)象，說明如是氯離子過少；</p><div

style="text-indent:25px">目前主流的鍍銅方法是有化學(xué)鍍銅和電解鍍銅這兩種的，不管是化學(xué)鍍銅還是電解鍍銅都是可以完成鍍銅工藝的。兩種鍍銅方法在鍍層厚度、前處理和所需的化學(xué)工藝設(shè)備上都是有所不同的?；瘜W(xué)鍍銅的鍍層厚度是比較均勻的，因?yàn)榛瘜W(xué)溶液的分散力比較完善，沒有明顯的邊緣效應(yīng)，適合各種形狀復(fù)雜的物件進(jìn)行鍍銅，而電解鍍銅相比起來則會因受力線分布不均勻的限制比較難達(dá)到鍍層厚度均勻的情況，所以通常對于電解鍍銅還是比較適用在成本較低、形狀及面積較小的物件的鍍銅。若通過添加鹽酸來解決低電流密度區(qū)鍍層"無光澤"，不一定是氯離子濃度太低而造成的，需分析其真正的原因。南京筆記本外殼鍍銅</p><p
