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，惠東柜員機(jī)控制面板鍍銀工藝.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(xì)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(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，惠東柜員機(jī)控制面板鍍銀工藝，惠東柜員機(jī)控制面板鍍銀工藝，膜層均勻。鍍液一定要謹(jǐn)慎保管處理?！∈紫儒冦y層的厚度要把握好，當(dāng)然厚度相對于不同的場合也是不一樣的；惠東柜員機(jī)控制面板鍍銀工藝</p><div

style="text-indent:25px">國內(nèi)國外對于防止銀變色方法各有各的方法，但是總體來說是八九不離十吧。國內(nèi)目前采用的主流方法有：化學(xué)鈍化、電化學(xué)鈍化、預(yù)鍍膜、脈沖電鍍、有機(jī)化合鈍化處理、電泳法和涂有機(jī)溶劑保護(hù)層等方法。我們拿化學(xué)鈍化和脈沖電鍍進(jìn)行對比說明：化學(xué)鈍化采用重鉻酸鹽溶液處理，在表面形成氧化銀和鉻酸銀薄膜。鉻酸鹽鈍化成本低，操作簡單，維護(hù)方便，但這種膜抗變色能力較差。脈沖電鍍采用間歇式供電，陰極電位隨時間作周期性變化，這樣可以提高陰極電流效率，減少***，增加銀層的密度。</p><p style="text-indent:25px">純銀飾品和鍍銀飾品在價格上相差很大，因此有些不良商家會用鍍銀飾品冒充是純銀飾品，基本上純銀飾品都會放有925純銀、955純銀和999純銀標(biāo)簽的的，但是這樣的標(biāo)簽辨別顯然是太過于小兒科化，隨便生產(chǎn)一個也能讓鍍銀的產(chǎn)品冒充為純銀產(chǎn)品。純銀產(chǎn)品質(zhì)地比價柔軟、硬度低，使用指甲稍用力就能劃出淺痕或者是牙咬會留有牙印，而鍍銀的基材硬度都是要高于純銀的。也可以使用折彎法對其硬度進(jìn)行測試，純銀質(zhì)軟，容易折彎；也就是說純度越低，硬度越大越不容易折彎。購買混來的飾品回來也可以使用稀酸浸泡進(jìn)行分辨，也可直接簡單一點用磨擦看看，磨擦完出現(xiàn)其他金屬顏色說明是鍍銀產(chǎn)品，或者是磨擦出配合稀酸看看，有氣泡說明是鍍銀產(chǎn)品。如果是在鎳基上鍍銀，可以采用銅基用的預(yù)鍍液，但是在鍍前要在50％的鹽酸溶液中預(yù)浸l0～30s；</p><div
