style="text-indent:25px">對(duì)金屬表面進(jìn)行電鍍處理的工藝歷史已經(jīng)有一兩百年的了，盡管歷史比較久，但是其實(shí)際的改變可能更多的是趨向于鍍種的增多和鍍液處理的方式變得更加環(huán)保而已。絕大部電鍍加工廠(chǎng)家電鍍的時(shí)候，會(huì)把鍍層金屬或者是其他不溶性材料作為陽(yáng)極，而需鍍的工件則作為陰極處理，電鍍過(guò)程中會(huì)把鍍層金屬的陽(yáng)離子在需鍍工件表面被還原形成鍍層。為了保證其他因素的干擾和鍍出來(lái)的膜層質(zhì)量效果，需要時(shí)用鍍層金屬陽(yáng)離子的溶液作為電鍍時(shí)使用的電鍍液。對(duì)于電鍍液的后期處理要確保符合環(huán)保要求。</p><p style="text-indent:25px">國(guó)內(nèi)國(guó)外對(duì)于防止銀變色方法各有各的方法，但是總體來(lái)說(shuō)是八九不離十吧。國(guó)內(nèi)目前采用的主流方法有：化學(xué)鈍化、電化學(xué)鈍化、預(yù)鍍膜、脈沖電鍍、有機(jī)化合鈍化處理、電泳法和涂有機(jī)溶劑保護(hù)層等方法。我們拿化學(xué)鈍化和脈沖電鍍進(jìn)行對(duì)比說(shuō)明：化學(xué)鈍化采用重鉻酸鹽溶液處理，在表面形成氧化銀和鉻酸銀薄膜。鉻酸鹽鈍化成本低，操作簡(jiǎn)單，維護(hù)方便，但這種膜抗變色能力較差。脈沖電鍍采用間歇式供電，陰極電位隨時(shí)間作周期性變化，這樣可以提高陰極電流效率，減少***，增加銀層的密度。預(yù)鍍液一般分為兩類(lèi)，其標(biāo)準(zhǔn)的組成如下：鋼鐵等基材上的預(yù)鍍銀；銅基材上的預(yù)鍍銀。</p><div

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。在無(wú)氰電鍍方面，鍍鋅和鍍銅均已獲得工業(yè)性生產(chǎn)的成效，但鍍銀的差{距則較大。寧波觸屏筆外殼鍍銀多少錢(qián)</p><p
