在鍍銅的時(shí)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(gè)是十分影響鍍銅純度的。可以使用鍍銅稀釋法，根據(jù)鐵離子的含量讓其稀釋后根據(jù)檢測(cè)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(huì)使用強(qiáng)酸陽(yáng)離子交換樹(shù)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(guò)濾和去除。這三種方法是常見(jiàn)的用來(lái)去除鍍銅溶液里鐵雜質(zhì)的操作方法。減少麻點(diǎn)的產(chǎn)生，可適時(shí)將鍍液進(jìn)行活性炭粉過(guò)濾處理；南京觸屏筆外殼鍍銅工藝</p><p
