style="text-indent:25px">鍍銀跟其他電鍍或者化學(xué)鍍一樣，在鍍銀過(guò)程中控制或者操作不當(dāng)也是會(huì)出現(xiàn)鍍出來(lái)的膜層出現(xiàn)不平整的情況，出現(xiàn)不平整的情況可能是以下原因造成的：鍍銀加工工藝不合理或電鍍時(shí)間不夠。在鍍銀的過(guò)程中要是時(shí)間太短或者電流太小，都會(huì)導(dǎo)致出現(xiàn)電鍍不平整的情況。電鍍件毛坯表面過(guò)于粗糙或不好。過(guò)于粗糙的表面要各到質(zhì)量的沉積電鍍層相對(duì)更困難，特別是一些壓鑄不良的產(chǎn)品就不能得到合格的電鍍層。電鍍液性能差，導(dǎo)致整平性能不好，可以對(duì)鍍液進(jìn)行調(diào)整重新配置。</p><p style="text-indent:25px">鍍銀工藝流程總結(jié)起來(lái)包括除油、拋光、鈍化、酸活化、預(yù)鍍銀、銀保護(hù)和水洗這幾個(gè)流程。除油可以簡(jiǎn)單的理解為出去油污，除油的方式包括有高溫除油、滾桶出游、電解除油和聯(lián)合方式除油。拋光則是進(jìn)一步去除零件表面的氧化層油污層為工件提供一個(gè)完整的膜層。鈍化則是處理拋光工序后殘留在零件表面上的殘?jiān)?。酸活化則是處理鈍化工藝的膜層，使得零件的表面活性和鍍層更加具有結(jié)合力。預(yù)鍍銀工序則是為了讓那個(gè)加工件的表面形成銅銀絡(luò)合物，增加加工件和鍍層的結(jié)合力并具有防變色功能。銀保護(hù)工序則是讓鍍層表面在形成以銀絡(luò)合物保護(hù)膜防止銀鍍層氧化變黑。水洗則是為了清洗各工序殘留的溶劑污漬。也就是在尋找更好的絡(luò)合劑和添加劑、輔助劑。在這方面取得進(jìn)展是完全有可能的。</p><div

電鍍工藝中不僅前處理工作十分重要，后處理工作也是非常重要的，很多電鍍產(chǎn)品鍍膜中并沒(méi)有出現(xiàn)差錯(cuò)，但是忽略了前處理和鍍膜后處理工序忽略而造成的。電鍍后處理的鍍層表面上不應(yīng)該留有其他的鍍液，不要污染鍍層。裝飾性鍍層，經(jīng)鍍后處理后要保持原來(lái)的光澤與色彩，并且要能維持長(zhǎng)久不脫色、變色，以滿足用戶的觀賞需要。防護(hù)性鍍層既要滿足防護(hù)性能的要求，也要保持其金屬光澤，即在保護(hù)其外觀的情況下，要能達(dá)到鹽霧試驗(yàn)、濕熱試驗(yàn)及日照試驗(yàn)等的要求。實(shí)際上電鍍的后處理主要就是細(xì)節(jié)問(wèn)題，用來(lái)提高鍍層的耐腐蝕性能和使用壽命。擴(kuò)大了推薦工藝配方的空間，這將使無(wú)氰鍍銀的鍍液性能、鍍層質(zhì)量和鍍液管理都會(huì)有所提升。深圳檢測(cè)儀外殼鍍銀多少錢</p><p
