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。因為在元素周期里，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，珠海傳感器外殼鍍銀工藝.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.鍍銀的性能特點包括有:鍍層應(yīng)呈銀白色,結(jié)晶細致平滑;與空氣接觸會逐漸氧化變色，遇硫會變黑;接觸電阻低，導電性能極好;導熱性能好;防粘結(jié)性強;易焊接;具有優(yōu)良的反光特性;表面光潔銀亮，珠海傳感器外殼鍍銀工藝，珠海傳感器外殼鍍銀工藝，膜層均勻。鍍液一定要謹慎保管處理。脈沖電源技術(shù)用在無氰鍍銀上應(yīng)該有更為明顯的效果。珠海傳感器外殼鍍銀工藝</p><div

style="text-indent:25px">鍍銀跟其他電鍍或者化學鍍一樣，在鍍銀過程中控制或者操作不當也是會出現(xiàn)鍍出來的膜層出現(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間不夠。在鍍銀的過程中要是時間太短或者電流太小，都會導致出現(xiàn)電鍍不平整的情況。電鍍件毛坯表面過于粗糙或不好。過于粗糙的表面要各到質(zhì)量的沉積電鍍層相對更困難，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，導致整平性能不好，可以對鍍液進行調(diào)整重新配置。珠海傳感器外殼鍍銀工藝銀很容易拋光，有美麗的銀白色。化學性質(zhì)穩(wěn)定，但其表面非常容易與大氣中的硫化物、氯化物等反應(yīng)而變色。</p><div

style="text-indent:25px">鍍銀過程并非一次性完成的，會先經(jīng)過預(yù)鍍銀工序，預(yù)鍍銀能防止工件直接進如銀槽銅與銀一字置換以及銀層結(jié)合力。預(yù)鍍銀的原理是鍍液中采用低主鹽高絡(luò)合物組成，不僅能有效降低置換反反應(yīng)的速度，而且能讓鍍液有較高的絡(luò)合度從而提高陰極化，讓鍍層或者一層結(jié)晶致密且絡(luò)合度良好的過渡層。借助化學反應(yīng)原理，在電的作用下，銀離子會在工件上得到電子而生成銀單質(zhì)，從而沉積到工件表面上，而不溶性的陽極只會做析氧返傭。鍍銀中使用的鍍液主要是由**銀鉀、**鉀配置而成的。</p><p style="text-indent:25px">預(yù)鍍銀處理完后就開始鍍銀工藝了，鍍銀的目的是作為一種鍍層在工件上，在導電設(shè)備上降低工件使用過程中接觸電阻提高導電性能，或者是裝飾功能用在飾品上。鍍銀的原理與預(yù)鍍銀原理基本一致，都屬于化學反應(yīng)原理，在電的作用下，銀板會失去電子生產(chǎn)銀離子溶解于鍍液中，陰離子在產(chǎn)品得到電子而生成銀單只，并沉積到工件上面。**銀鉀為鍍銀中鍍液的主鹽，提供金屬鹽，它含有的金屬銀約為五成左右；**鉀則在鍍銀中鍍液起到鍍液絡(luò)合劑的作用，用來維持一定量的游離**鉀，穩(wěn)定鍍液，提高膜層結(jié)晶效率。銀的標準電極電位(25℃，相對于氫標準電極，Ag／Ag+)為+0．799V；</p><div

style="text-indent:25px">很多人聽說過鍍銀，但是沒有聽過鍍銠銀，其本質(zhì)上指的就是鍍銠，因為與銀基本上很難從外觀分別出來，因此被人們稱為銠銀。銠屬于惰性金屬，因此電鍍之后鍍層的穩(wěn)定性和亮度的視覺保持時間比其他電鍍工藝保持時間更長，但是鍍銠的價錢上是要比其他工藝要貴上少許的。鍍銠工藝多用于首飾產(chǎn)品的電鍍上，像大家蕞常見的鉑金首飾，鉑金材質(zhì)本身就算經(jīng)過拋光，也不會很亮，只有經(jīng)過鍍銠之后才會呈亮發(fā)光。除了銀、鉑金可以鍍銠外，銅類金屬也是可以采用鍍銠工藝進行加工，常用在首飾行業(yè)上。無氰鍍銀是目前國內(nèi)外電鍍工作者研究的一個重要課題。珠海傳感器外殼鍍銀工藝</p><p style="text-indent:25px">使表面處于活化狀態(tài)。也可以采用陰極電解的方法讓鎳表面活化，這樣可以進一步提高鍍層的結(jié)合力。珠海傳感器外殼鍍銀工藝</p><p> 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或電化學處理，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。珠海傳感器外殼鍍銀工藝</p><p
