有些情況下﹐若鍍液中主鹽的金屬離子為簡單離子時﹐則鍍層晶粒粗大﹐因此﹐要采用絡(luò)合離子的鍍液。獲得絡(luò)合離子的方法是加入絡(luò)合劑﹐即能絡(luò)合主鹽的金屬離子形成絡(luò)合物的物質(zhì)。絡(luò)合物是一種由簡單化合物相互作用而形成的“分子化合物”。在含絡(luò)合物的鍍液中﹐影響電鍍效果的主要是主鹽與絡(luò)合劑的相對含量﹐即絡(luò)合劑的游離量﹐而不是含量。 </p> <p> 3.附加鹽 </p> <p> 附加鹽是電鍍中除主要鹽外的某些堿金屬或堿土金屬鹽類﹐主要用于提高電鍍液的導(dǎo)電性﹐對主鹽中的金屬離子不起絡(luò)合作用。有些附加還能改善鍍液的深鍍能力﹐分散能力﹐產(chǎn)生細(xì)致的鍍層。湖南自動電鍍設(shè)備中電鍍液成分視鍍層不同而不同，但均含有提供金屬離子的主鹽，能絡(luò)合主鹽中金屬離子形成絡(luò)合物的絡(luò)合劑。</p><div

鍍液中的光亮劑﹐整平劑﹐潤濕劑等添加劑能明顯改善鍍層。對此添加劑有無機和有機之<。無機添加劑起作用的原因是由于它們在電解液中形成散度的氫氧化物或硫化物膠體﹐吸附在陰極表面阻礙金屬析出﹐提高陰極極化作用。有機添加劑起作用的原因是這類添加劑多為表面活性物質(zhì)﹐它們會吸附在陰極表面形成一層附膜﹐阻礙金屬析出﹐因而提高陰極極化作用。另外﹐<些有機添加劑在電解液中形成膠體﹐會與金屬離子絡(luò)合形成膠體-金屬離子型絡(luò)合物﹐阻礙金屬離子放電而提高陰極極化作用。 </p><p> 1993年我國機械工業(yè)部專家編制了電鍍用整流設(shè)備的標(biāo)準(zhǔn)(JB/T1504-1993)，對我國設(shè)計和生產(chǎn)的電鍍整流器的型號、規(guī)格、技術(shù)參數(shù)等都作出了相關(guān)規(guī)定。隨著電力科學(xué)技術(shù)的進步，在整流電源的設(shè)計和制作上已經(jīng)有很大改進，很多電鍍電源已經(jīng)向多功能、大功率、小體積等方向發(fā)展。自動換向、可調(diào)脈沖、平滑調(diào)節(jié)等都已經(jīng)是常見的功能。常用的風(fēng)冷式可控硅整流器的技術(shù)規(guī)格見表1。 </p> <p> 電鍍槽 </p> <p> 電鍍用的鍍槽包括電鍍生產(chǎn)中各工序的專用槽體。不光只是電鍍槽，還包括前處理用的除油槽、酸洗槽和清洗槽、活化槽，后處理的鈍化槽、熱水槽等。由于電鍍用槽仍然屬于非標(biāo)準(zhǔn)設(shè)備，其規(guī)格和大小有很大變通空間的設(shè)備。小到燒杯，大到水池都可以用來做鍍槽，因為只要能將鍍液裝進去而不流失的裝置，就可以做鍍槽用，就是實際電鍍工業(yè)生產(chǎn)中所用的鍍槽也是五花八門，并沒有統(tǒng)一的標(biāo)準(zhǔn)，這種狀況對加強電鍍管理是不利的。在有些情況下，如鍍鉻，是采用鉛、鉛銻合金制成的不溶性陽極，它只起傳遞電子、導(dǎo)通電流的作用。</p><div

當(dāng)金屬電極浸入含有該金屬離子的溶液中時﹐存在如下的平衡﹐即金屬失電子而溶解于溶液的反應(yīng)和金屬離子得電子而析出金屬的鋟從τν時存在﹕ </p> <p> <br /> </p> <p> Mn++ne 電鍍原理（一）電鍍的基本知識 M </p> <p> <br /> </p> <p> 平衡電位與金屬的本性和溶液的溫度﹐濃度有關(guān)。為了精確比較物質(zhì)本性對平衡電位的影響﹐人們規(guī)定當(dāng)溶液溫度為250C﹐金屬離子的濃度為1mol/L時﹐測得的電位叫標(biāo)準(zhǔn)電極電位。標(biāo)準(zhǔn)電極電位負(fù)值較大的金屬都易失掉電子被氧化﹐而標(biāo)準(zhǔn)電極電位正值較大的金屬都易得到電子被還原。 </p> <p> <br /> </p> <p> B.極化 </p> <p> <br /> </p> <p> 所謂極化就是指有電流通過電極時降緙電位偏離平衡電極電位的現(xiàn)象。所以﹐又把電流-電位曲線稱為極化曲線。產(chǎn)生極化作用的原因主要是電化學(xué)極化和濃差極化。分別試驗這些保護材料的耐酸、堿腐蝕、耐高溫（堿蝕溶液比較高溫度80℃左右）性能以及可剝離性。湖南自動電鍍設(shè)備</p><p

整流器的管理不只是電工人員的事，電鍍企業(yè)要將每臺整流器定人定崗管理。即由使用人負(fù)責(zé)日常的管理，對整流器進行使用監(jiān)視和維護，比如，嚴(yán)禁操作過程中的電極短路，不讓鍍液等腐蝕性液體灑到整流器上等，要每天進行表面清潔維護，遇有異常，立即關(guān)機并通知電工到場處理，非電工人員不得擅自開拆和修理整流電源。當(dāng)然提倡高級電鍍工要獲得相應(yīng)電工資格，從而有動手處理整流器故障的能力和資格。
