style="text-indent:25px">銀本身的性質(zhì)較為活潑，其在鍍液中的穩(wěn)定性能也是比較差的，容易引起鍍液分解。因?yàn)樵谠刂芷诶?，銀是屬于貴金屬中的一員，它很難與其他的金屬形成合金鍍層.鍍銀用的鍍液也是比較有限的,大都數(shù)使用的都是含有**物的堿性溶液,**物大家都明白是什么物質(zhì)了.鍍銀的性能特點(diǎn)包括有:鍍層應(yīng)呈銀白色,結(jié)晶細(xì)致平滑;與空氣接觸會(huì)逐漸氧化變色，遇硫會(huì)變黑;接觸電阻低，導(dǎo)電性能極好;導(dǎo)熱性能好;防粘結(jié)性強(qiáng);易焊接;具有優(yōu)良的反光特性;表面光潔銀亮，膜層均勻。鍍液一定要謹(jǐn)慎保管處理。</p><p style="text-indent:25px">依據(jù)鍍銀物件的變色原理和各種因素對(duì)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(lèi)：第一種是在物件表面進(jìn)行化學(xué)鈍化處理，使得銀層表面形成一層氧化物保護(hù)層，以此達(dá)到延緩變色的速度；第二種是銀表面涂上保護(hù)膜來(lái)屏蔽銀層表面和紫外線(xiàn)、氧氣、腐蝕物質(zhì)的接觸，來(lái)達(dá)到延緩銀層變色的目的；蕞后一種是改善銀色工藝條件，來(lái)提供鍍銀層本其本身的防變色能力。這是對(duì)鍍銀層目前采用比較主流的防變色（延緩變色）的處理方法。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。</p><div

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。銀也大量用于制作工藝品、餐具、錢(qián)幣、樂(lè)器等，或者作為這些制品的表面裝飾鍍層。中山車(chē)載攝像頭外殼鍍銀工藝</p><p style="text-indent:25px">銀也是大家熟悉的貴金屬，化學(xué)元素符號(hào)為Ag，原子序數(shù)47，相對(duì)原子質(zhì)量107.9，熔點(diǎn)960.8℃，沸點(diǎn)2212℃。中山車(chē)載攝像頭外殼鍍銀工藝</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(xiàng)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(lái)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。中山車(chē)載攝像頭外殼鍍銀工藝</p><p
