style="text-indent:25px">銀材料上電鍍白金也是近些年逐漸流行起來(lái)的一種電鍍工藝，電解鍍白金是采用正負(fù)電荷相吸的原理，在電介質(zhì)中帶電的貴金屬離子被異質(zhì)電荷的受體電場(chǎng)吸引并吸附在其上，在受體上形成貴|金屬涂層。純銀鍍白金基本上都是在裝飾行業(yè)中使用，因?yàn)榧冦y飾品在遇上空氣中的二氧化硫等含硫氣體或者含硫物質(zhì)，會(huì)發(fā)生反應(yīng)而變黑。為了防止變黑和增加美觀度，所以在表面上要鍍白色金屬。電鍍不*能使設(shè)備表面美觀，還能防止生銹、腐蝕，因此在生產(chǎn)實(shí)踐中得到諸多應(yīng)用。另外，飾品行業(yè)選擇用純銀鍍白金這種方式加工銀飾品，也能使得產(chǎn)品價(jià)錢(qián)有更多的利潤(rùn)空間。南京檢測(cè)儀外殼鍍銀工藝在正式鍍銀前，一般都要采用預(yù)鍍措施。這種預(yù)鍍液的要點(diǎn)是有很高的**物含量和很低的銀離子濃度。</p><div

style="text-indent:25px">鍍銀的工藝流程是比較復(fù)雜的，銀金屬本身是比較貴重的金屬，不處理好的造成的浪費(fèi)也會(huì)加大廠家的生產(chǎn)加工成本。鍍銀基本的流程包括有電鍍除油、熱水冷水洗、化學(xué)除銹、二次水洗、**頂鍍銅、三次水洗、酸性光亮鍍銅、四次水洗、光亮鍍鎳、五次水洗、沖擊鍍銀、去離子水洗、鈍化、浸400有機(jī)膜、烘干、浸光亮漆保護(hù)膜、二次烘干、檢驗(yàn)質(zhì)檢。從這個(gè)工藝流程中不難看出水在其中的參與是多么的重要，所以電鍍中不*需要對(duì)廢液進(jìn)行處理，而且對(duì)于電鍍中的廢水進(jìn)行處理。</p><p> 電鍍工藝中不*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(méi)有出現(xiàn)差錯(cuò)，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(lái)的光澤與色彩，并且要能維持長(zhǎng)久不脫色、變色，以滿足用戶的觀賞需要。防護(hù)性鍍層既要滿足防護(hù)性能的要求，也要保持其金屬光澤，即在保護(hù)其外觀的情況下，要能達(dá)到鹽霧試驗(yàn)、濕熱試驗(yàn)及日照試驗(yàn)等的要求。實(shí)際上電鍍的后處理主要就是細(xì)節(jié)問(wèn)題，用來(lái)提高鍍層的耐腐蝕性能和使用壽命。由于銀有非常正的電極電位，除了電位比它正的極少數(shù)金屬如金、白金等外；</p><div

style="text-indent:25px">預(yù)鍍銀處理完后就開(kāi)始鍍銀工藝了，鍍銀的目的是作為一種鍍層在工件上，在導(dǎo)電設(shè)備上降低工件使用過(guò)程中接觸電阻提高導(dǎo)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(xué)反應(yīng)原理，在電的作用下，銀板會(huì)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(lái)維持一定量的游離**鉀，穩(wěn)定鍍液，提高膜層結(jié)晶效率。這對(duì)于改善鍍層質(zhì)量和改善鍍液性能都是很有意義的。中山可視電話機(jī)鍍銀</p><p
