style="text-indent:25px">滾鍍和掛鍍工藝是有區(qū)別的。滾鍍?nèi)Q為滾筒電鍍，一般而言適用于小零件的加工，珠海醫(yī)用探測器前殼鍍銀，是把相關(guān)數(shù)量的小零件放在**的滾筒內(nèi)，在滾動(dòng)狀態(tài)下簡介導(dǎo)電的方式來讓零件表面沉積各種金屬或合金鍍層，從而讓零件表面防護(hù)裝飾和各種功能性目的的一種電鍍技工方式。掛鍍則與滾鍍相反，珠海醫(yī)用探測器前殼鍍銀，常用在比較大的零件加工商，能鍍層的產(chǎn)品數(shù)量會(huì)比滾鍍少，珠海醫(yī)用探測器前殼鍍銀，鍍層的厚度要比滾鍍的產(chǎn)品厚度要稍微厚一點(diǎn)，能達(dá)到10納米以上，像汽車的保險(xiǎn)杠，自行車車把等都會(huì)使用掛鍍工藝進(jìn)行加工生產(chǎn)。</p><div

style="text-indent:25px">國內(nèi)國外對(duì)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(duì)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(shí)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><div

style="text-indent:25px">純銀飾品和鍍銀飾品在價(jià)格上相差很大，因此有些不良商家會(huì)用鍍銀飾品冒充是純銀飾品，基本上純銀飾品都會(huì)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(gè)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(jià)柔軟、硬度低，使用指甲稍用力就能劃出淺痕或者是牙咬會(huì)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(duì)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(diǎn)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。</p><div
