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)品鍍膜中并沒有出現(xiàn)差錯，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的光澤與色彩，并且要能維持長久不脫色，佛山電子觸摸筆鍍銀、變色，以滿足用戶的觀賞需要。防護性鍍層既要滿足防護性能的要求，佛山電子觸摸筆鍍銀，也要保持其金屬光澤，即在保護其外觀的情況下，要能達到鹽霧試驗、濕熱試驗及日照試驗等的要求，佛山電子觸摸筆鍍銀。實際上電鍍的后處理主要就是細節(jié)問題，用來提高鍍層的耐腐蝕性能和使用壽命。第二次再在銅基預(yù)鍍液中預(yù)鍍，這樣才能保證鍍層的結(jié)合力。佛山電子觸摸筆鍍銀</p><div

style="text-indent:25px">依據(jù)鍍銀物件的變色原理和各種因素對鍍銀物件變色速度的影響，能把防止鍍銀件變色的方法總結(jié)成這幾類：第一種是在物件表面進行化學(xué)鈍化處理，使得銀層表面形成一層氧化物保護層，以此達到延緩變色的速度；第二種是銀表面涂上保護膜來屏蔽銀層表面和紫外線、氧氣、腐蝕物質(zhì)的接觸，來達到延緩銀層變色的目的；蕞后一種是改善銀色工藝條件，來提供鍍銀層本其本身的防變色能力。這是對鍍銀層目前采用比較主流的防變色（延緩變色）的處理方法。佛山醫(yī)用器械鍍銀廠家在印制板、接插件、波導(dǎo)等電子和通信產(chǎn)品中扮演了重要角色，也是電鑄功能性制品或工藝制品的重要鍍種。</p><div

style="text-indent:25px">電鍍絕不能等同于說是鍍金鍍銀，電鍍它是使用電解原理在某些金屬外表上鍍上薄膜在其他金屬或合金的過程，屬于材料表面處理的電化學(xué)處理概念。經(jīng)過電鍍的金屬材料其外表附著一層金屬膜，用來防止金屬修飾，提高耐磨性，導(dǎo)電性，反光性和裝飾作用的。而鍍金鍍銀則是具體的一種鍍種方式，以鍍金為例，它通常是用來裝飾用的，金對于目前人類社會而言都是具有舉足輕重的意義，所以常使用鍍金裝飾其他物品，另外對于電子元器件中也會使用到鍍金工藝來提高電子內(nèi)部的導(dǎo)電和傳遞信息的作用。</p><p style="text-indent:25px">鍍銀的那一層銀極易拋光，具有高反光和良好的導(dǎo)熱、導(dǎo)電、焊接性能。（銀的導(dǎo)電性比銅更好），鍍銀常用在裝飾行業(yè)，尤其是戒指、項鏈等裝飾品。而在電子工業(yè)、通訊和儀器儀表制造業(yè)中，絕大部分采用鍍銀工藝用來降低金屬零部件之間的電阻，提高金屬的焊接本領(lǐng)。因其具有極好的反光性能，所以在探照燈和其他反射器材中的金屬面也是采用鍍銀的。但是我們需要注意的是，如果在潮濕的大氣中銀容易產(chǎn)生“銀須”，導(dǎo)致短路現(xiàn)象，所以在印刷電路板中不建議使用鍍銀。銀的標(biāo)準(zhǔn)電極電位(25℃，相對于氫標(biāo)準(zhǔn)電極，Ag／Ag+)為+0．799V；</p><div

style="text-indent:25px">鍍銀工藝蕞早出現(xiàn)在十九世紀(jì)元年，蕞早的鍍銀**是英國伯明翰兩兄弟與1838年提出申請的，當(dāng)時電鍍銀使用的電鍍液是呈堿性的**物鍍液。到現(xiàn)在為止，鍍銀液的配方和早期的配方基本上沒有太大的區(qū)別，***的區(qū)別可能在于提高了銀配位離子濃度從而達到快速鍍銀的目的罷了。近些年來，快速發(fā)展的額電子元器件都選擇性鍍銀，比如引線框架的選擇性鍍銀，并采用噴射鍍的方法進行鍍銀。電鍍銀所用的電流密度高達300~3000A/dm，鍍液中**銀鉀[KAg(CN)2]的濃度高達40~75g/L，陽極采用白金或鍍鉑的鈦陽極。加上帶電下槽，這樣在極短的時間內(nèi)(一般是30秒～l分鐘)；佛山電子觸摸筆鍍銀</p><p

style="text-indent:25px">零部件鍍銀的產(chǎn)品有諸多作用，鍍銀可使產(chǎn)品防止腐蝕，增加導(dǎo)電率、反光性和美觀。適用于電器、儀器、儀表和照明用具等制造工業(yè)。例如銅或銅合金制件鍍銀時，須先經(jīng)除油去銹;再預(yù)鍍薄銀或浸入由**等配成的溶液中，進行汞化處理，使在制件表面鍍上一層汞膜;然后將制件作陰極，純銀板作陽極，浸入由硝酸銀和**鉀所配成的**銀鉀電解液中，進行電鍍。電器、儀表等工業(yè)還采用無氰鍍銀。為了防止銀鍍層變色，通常要經(jīng)過鍍后處理，主要是浸亮、化學(xué)和電化學(xué)鈍化，鍍貴金屬或稀有金屬或涂覆蓋層等。佛山電子觸摸筆鍍銀</p><p
