style="text-indent:25px">電流密度對鍍銅的影響是比較大的，電流密度越低，結(jié)晶越細(xì)膩柔軟，鍍層灰暗，硬度高脆性大，結(jié)晶粗大，沉積速度慢，生產(chǎn)效率低。電流密度越高，結(jié)晶越粗大，沉積速度快，生產(chǎn)效率高。電流密度適中，可獲得光亮度銅層，這種銅層硬度較高，有細(xì)而稠密的網(wǎng)狀裂紋。合理選擇電解鍍銅的電流密度，是或者理想的鍍銅層、保持適當(dāng)加工效率的關(guān)鍵。此外，電解溶液中不同的配方，電流密度范圍也是相同，在實(shí)際加工生產(chǎn)中會采用中等溫度和中等電流密度進(jìn)行操作，或者是相對較低的溫度和較低電流密度進(jìn)行操作，根據(jù)實(shí)際加工情況再進(jìn)行校正。惠東筆記本外殼鍍銅鍍液中只要有銅存在，電沉積時，銅離子總是比銅離子優(yōu)先析出，故造成鍍層粗糙、低電流密度區(qū)不光亮等情況。</p><div

style="text-indent:25px">電解鍍銅是需要用在電以及各種用電設(shè)備配合才能完成鍍膜加工的一種鍍膜方法。對于電解鍍銅電源的選擇主要考慮這三個要求：需要符合電鍍銅工藝所需要的規(guī)范，主要指的是電源的功率大小、波形指標(biāo)、電流電壓值及可調(diào)范圍。電源要具有合理性、安全性等可靠性能，對于電源的線路特點(diǎn)和冷卻方式也是需要考慮到?？紤]到電源價格層面的性價比。需要明白的是確定一個鍍種及其所有的鍍槽要配置多大的和什么樣的電源是實(shí)施電鍍生產(chǎn)首要的重要工作，這一點(diǎn)不管是鍍層、鍍鋅還是鍍鎳等常規(guī)的電鍍方法都是要考慮到的。</p><p> 電鍍廠使用過的鍍液廢水都要進(jìn)行處理達(dá)標(biāo)后才能進(jìn)行排放，以鍍錫銅排常為例，錫是一種銀白色的金屬，有?，但是具有良好的焊接性和延展性。鍍錫中使用的是酸性鍍錫，***鍍錫成本低，鍍液易于控制，鍍層光亮細(xì)致，但分散能力較差，鍍液廢水處理困難。堿性鍍錫具有成分簡單，鍍液分散能力好，鍍層細(xì)致，孔隙少，釬焊性能好的優(yōu)點(diǎn)，但是存在操作溫度高，能耗大，電流使用范圍窄，電流效率低，不能獲得光亮鍍層，鍍層硬鍍小等缺點(diǎn)。不管是酸性還是堿性鍍錫，都要對鍍液廢水進(jìn)行處理符合排放標(biāo)準(zhǔn)才行。出現(xiàn)電鍍故障時，應(yīng)仔細(xì)觀察故障現(xiàn)象(該廠以為故障為鍍層粗糙，實(shí)為細(xì)麻砂)；</p><div
