style="text-indent:25px">有些產(chǎn)品在進(jìn)行鍍鋅工藝時，還需要預(yù)先鍍上一層銅才能進(jìn)行鍍鋅1工藝，那么為什么不直接鍍兩層鋅？這樣做的原理在于什么？其實之所以要這樣操作是因為直接鍍鋅會導(dǎo)致局部電流過高，導(dǎo)致掛鍍具頭把產(chǎn)品的鍍層擊穿而出現(xiàn)漏鍍的現(xiàn)象，導(dǎo)致導(dǎo)電性差。預(yù)先鍍一層銅能降低電鍍產(chǎn)品的電阻，使鍍錫過程中電流參數(shù)更加穩(wěn)定，杭州手機攝像頭基座鍍銅多少錢。需要明白的是在鐵質(zhì)，杭州手機攝像頭基座鍍銅多少錢，杭州手機攝像頭基座鍍銅多少錢、塑料產(chǎn)品電鍍的時候也是需要預(yù)先鍍一層銅的，這樣做的原因都是不讓高電流把相關(guān)的鍍層擊穿，導(dǎo)致產(chǎn)品不導(dǎo)電。</p><div

style="text-indent:25px">另外可以從鍍銅工件和改善幾何因素入手去排查這些會在鍍銅過程中造成鍍層不均勻的情況。在鍍銅過程會發(fā)現(xiàn)，同樣一批掛件，有的工件鍍出來的層會發(fā)花發(fā)霧面，反復(fù)鍍層也是無法解決，造成這樣的問題可能是上部工件與鍍液太近，所以其電力線比較低而影響質(zhì)量。改善鍍銅過程的幾何因素，可以采用象形陽極法、保護(hù)陰極法、輔**極法、調(diào)整陽極表面積法、控制鍍液導(dǎo)電空間法、多次鍍鉻法等方法，來改善電力線分布的均勻性，可以是單獨使用某一種方法，也可以是多種方法聯(lián)合使用。</p><div

style="text-indent:25px">電鍍鍍銅的方法工藝也有分步驟的，在加工商分為掛鍍、滾鍍、連續(xù)鍍和刷鍍等方式，這些加工工序的主要還是根據(jù)需要鍍件的尺寸和數(shù)量有關(guān)。掛鍍適用一般尺寸的制品，比如汽車保險杠、自行車車把等；滾鍍方式則適合用在小型物件，像銷子、墊圈等。連續(xù)鍍則通常使用在有一定批量的線材或者是帶材；刷鍍則只使用在局部鍍或者是修復(fù)。鍍層分為裝飾保護(hù)性鍍層和功能性鍍層兩類。裝飾保護(hù)性鍍層主要是在鐵金屬、非鐵金屬及塑料上的鍍鉻層，特別是鋼的銅-鎳-鉻層，鋅及鋼上的鎳鉻層。功能性則偏向某些功能的實現(xiàn)。</p><div
