style="text-indent:25px">國內(nèi)國外對于防止銀變色方法各有各的方法，但是總體來說是八九不離十吧。國內(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、有機化合鈍化處理、電泳法和涂有機溶劑保護層等方法。我們拿化學(xué)鈍化和脈沖電鍍進行對比說明：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，操作簡單，維護方便，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。合肥電子觸摸筆鍍銀廠家脈沖電源在貴金屬電鍍中已有較多應(yīng)用，其著眼點主要考慮節(jié)約貴金屬用量，并且主要還是用在**物電鍍工藝。</p><div

電鍍處理工序的后處理種類包括有除氫處理、鈍化保護處理。除氫處理對于電鍍后的產(chǎn)品來說是很重要的，這是因為鍍金屬離子在陰極上得到電子，氫離子也同樣會得到電子，生成原子態(tài)的氫，滲透到金屬鍍層內(nèi)部，使鍍層產(chǎn)生疏松，當(dāng)放置一段時間后，原子態(tài)的氫會結(jié)合生成氫氣而體積膨脹，這樣就導(dǎo)致鍍層產(chǎn)生針眼孔、鼓泡甚至脫落等不良缺點。而所謂的鈍化處理則指的是在溶液中進行化學(xué)或電化學(xué)處理，使得鍍層上形成一層堅實致密的、穩(wěn)定性高的薄膜的表面處理方法，鈍化使鍍層的耐腐蝕性能進一步的提高并增加表面光澤和抗污染的能力。 </p><p style="text-indent:25px">電鍍中使用的鍍液，要考慮到合理性和使用性。合理性和實用性需要考慮的包括溶液的總體濃度、添加的組分、溶液工作溫度等。電鍍中的鍍液很多人單純的認(rèn)為只要濃度高就行了，因為鍍液中離子濃度高能提高容許的蕞大電流密度，但是這樣會導(dǎo)致成本上升和污水處理成本的增加。電鍍中的組分也不是越多越好（電鍍添加劑），過多會導(dǎo)致電鍍過程難以控制和調(diào)整，且無法保持工藝的穩(wěn)定。電鍍液中的溫度能保持在常溫下是蕞為理想的了，這樣能節(jié)省設(shè)備的投入和能源消耗，但也并不是說鍍液升溫就會造成成本的增加，還要看時機保持的溫度和電鍍中所獲得的好處，根據(jù)綜合情況來判斷。這種預(yù)鍍過程由于時間很短，也被叫做閃鍍。</p><div

style="text-indent:25px">鍍銀工藝流程總結(jié)起來包括除油、拋光、鈍化、酸活化、預(yù)鍍銀、銀保護和水洗這幾個流程。除油可以簡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。拋光則是進一步去除零件表面的氧化層油污層為工件提供一個完整的膜層。鈍化則是處理拋光工序后殘留在零件表面上的殘渣。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。銀保護工序則是讓鍍層表面在形成以銀絡(luò)合物保護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。預(yù)鍍上一層厚度約0．5μm的銀鍍層，從而阻止了置換鍍過程的發(fā)生。合肥電子觸摸筆鍍銀廠家</p><p
