對(duì)于絕大多數(shù)人而言都是不能有效的分辨純銀和鍍銀的區(qū)別，外觀上兩者基本上是同一種樣式，因此在裝飾品行業(yè)很多不良商家會(huì)使用鍍銀產(chǎn)品來(lái)坑騙消費(fèi)者。鍍銀和純銀絕不是同一種產(chǎn)品，鍍銀只是單純的在基體表面上鍍上一銀層，其內(nèi)部可以是各種非銀物質(zhì)組成；而純銀產(chǎn)品則是因含量較為接近***銀的，鍍銀更多的是外在美，純銀更多的是內(nèi)在美。從飾品店購(gòu)買(mǎi)回來(lái)的產(chǎn)品可以防止高溫焊搶下燒紅，待產(chǎn)品冷卻后若是出現(xiàn)黑色、暗黑色或發(fā)黃的情況，則是鍍銀產(chǎn)品或銀含量不高的產(chǎn)品。而純銀產(chǎn)品則會(huì)呈現(xiàn)如白紙一般的顏色。這個(gè)方法是蕞為簡(jiǎn)單有效直接的方法，但是對(duì)于購(gòu)買(mǎi)回來(lái)的產(chǎn)品很多消費(fèi)者是不愿意這樣操作檢驗(yàn)的。 </p><p style="text-indent:25px">鍍銀材料也是需要進(jìn)行銀保護(hù)的，銀保護(hù)的目的是在銀層表面形成一層導(dǎo)電性和導(dǎo)熱性良好的保護(hù)膜，預(yù)防工件在使用的過(guò)程中銀層氧化而影響到設(shè)備的性能。其原理是通過(guò)浸泡或電解方式，在銀層表面吸附上一層具有物理、化學(xué)性質(zhì)良好的保護(hù)膜，隔離銀層與空氣或其他因素的接觸，防止銀表面氧化發(fā)黃發(fā)黑的現(xiàn)象。銀保護(hù)的鍍液配置，需要在電解槽內(nèi)加入四分之三體積的純凈水；然后加熱至工藝要求溫度；加入計(jì)算量的WST并攪拌均勻；補(bǔ)充純凈水到標(biāo)準(zhǔn)液位并攪拌均勻；蕞后是加溫到合適的工藝溫度，并進(jìn)行試產(chǎn)，出現(xiàn)問(wèn)題則需要停止進(jìn)行配置。銀和金一樣富于延展性，是導(dǎo)電、導(dǎo)熱極好的金屬，因此在電子工業(yè)特別是接插件、印制板等產(chǎn)品中有廣泛應(yīng)用。</p><div

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：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、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。其他金屬如銅、等大多數(shù)金屬在鍍銀時(shí)，都會(huì)因銀的電位較正而在電鍍時(shí)發(fā)生置換反應(yīng)，使鍍層結(jié)合力出現(xiàn)問(wèn)題。廣州5G信號(hào)盒外殼鍍銀工藝</p><p
