style="text-indent:25px">國(guó)內(nèi)國(guó)外對(duì)于防止銀變色方法各有各的方法，但是總體來(lái)說(shuō)是八九不離十吧。國(guó)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(shuō)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(jiǎn)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。**早提出**鉀絡(luò)合物鍍銀的是英國(guó)的G．Flikingtom，他于1838年就發(fā)明了這種鍍銀的方法。上海醫(yī)用探測(cè)器前殼鍍銀生產(chǎn)商</p><p style="text-indent:25px">由于無(wú)氰鍍銀層的電結(jié)晶尺寸明顯地大于**物鍍層，當(dāng)采用脈沖電流時(shí)，其晶粒改變的直觀效果會(huì)更為明顯。合肥手機(jī)攝像頭基座鍍銀廠商</p><p style="text-indent:25px">塑料材料進(jìn)行鍍膜通常會(huì)使用的方法是化學(xué)電鍍和真空電鍍兩種。我們都知道，塑料屬于絕緣材料，要想在塑料表面進(jìn)行電鍍的話，那么首先需要解決的問(wèn)題就是導(dǎo)電了。塑料化學(xué)電鍍分為表面粗話、表面敏化火花、沉積導(dǎo)電層后再進(jìn)行電鍍處理；而采用真空鍍膜的方式材料是不需要進(jìn)行電鍍的，該方法是在真空條件下讓金屬加熱蒸發(fā)并且貼覆在需度塑料的表面上，從而形成一層金屬膜的方法。按電鍍的定義而言，就應(yīng)該明白它主要是用來(lái)金屬或者半導(dǎo)體之間鍍上金屬和合金的，塑料自然是在排除其加工范圍內(nèi)的。合肥手機(jī)攝像頭基座鍍銀廠商</p><p
