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(huà)，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(huà)、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。</p><p> 脈沖無(wú)氰鍍銀是在磁場(chǎng)和脈沖電流作用下的無(wú)氰鍍銀工藝方法，屬于電化學(xué)鍍銀工藝技術(shù)領(lǐng)域。脈沖鍍銀工藝流程步驟如下：鍍件化學(xué)除油、水洗、化學(xué)除銹、水洗、光亮鍍鎳、水洗、活化處理、水洗、浸銀、水洗、脈沖鍍銀、鈍化處理、干燥、蕞后的成品。脈沖鍍銀的配方通常是使用硝酸銀、硫代硫|酸鈉、焦亞硫|酸鉀、硫|酸鉀、硼酸、光亮劑等。并使用機(jī)械攪拌，讓鍍液的PH值維持在，溫度控制在20-40攝氏度，控制好脈沖電流密度，并且陽(yáng)極蕞好是采用高純度的銀板。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
