12.收料系統(tǒng)：一般收料方式有水平式和垂直式。收料區(qū)須設(shè)有傳動(dòng)裝置(有些特殊的傳動(dòng)裝置不在收料系統(tǒng)內(nèi))，記數(shù)裝置，連動(dòng)開(kāi)關(guān)，收料裝置，紙轉(zhuǎn)盤，定位導(dǎo)輪，若生產(chǎn)速度很快時(shí)，更要設(shè)有緩沖接線。 </p> <p> 13.泵過(guò)濾機(jī)：一般分臥式泵和立式泵，其規(guī)格以HP馬力來(lái)區(qū)分，馬力越大，其流量也越大，過(guò)濾機(jī)濾心常用規(guī)格為1μ，5μ，10μ，μ數(shù)越小可過(guò)濾的顆粒越小，過(guò)濾的效果也就越好。一般建議金槽，鈀鎳槽使用1μ，而其他的使用5μ濾心，并且每周定期檢查。過(guò)濾時(shí)間越長(zhǎng)，效果越好，如能24小時(shí)過(guò)濾比較好。 </p> <p> 14.整流器：目前有可控制硅整流器，電晶整流器，變頻式整流器，脈沖整流器等。因?yàn)橹绷麟姴ǘ葧?huì)影響電流密度范圍，濾波度越小，可操作的電流密度也就越寬，通常濾波度須在3%以下。其中以變頻整流器比較好，濾波度約在0.1%。寧海電鍍?cè)O(shè)備多少錢電鍍層比熱浸層均勻，一般都較薄，從幾個(gè)微米到幾十微米不等。</p><div

電鍍過(guò)程是鍍液中的金屬離子在外電場(chǎng)的作用下﹐經(jīng)電極反應(yīng)還原成金屬原子并在陰極上進(jìn)行金屬沉積的過(guò)程。下圖(1-2)是電沉積過(guò)程示意圖﹐完成電沉積過(guò)程必須經(jīng)過(guò)以下三個(gè)步驟﹕ </p> <p> 液相傳質(zhì)﹕鍍液中的水化金屬離子或絡(luò)離子從溶液內(nèi)部向極界面遷移﹐到達(dá)陰極的雙電層溶液一側(cè)。 </p> <p> 電化學(xué)反應(yīng)﹕水化金屬離子或絡(luò)離子通過(guò)雙電層﹐并去掉它周圍的水化分子或配位體層﹐從陰極上得電子生成金屬原子。有三種方式﹕電遷移﹐對(duì)流和擴(kuò)散。 </p> <p> 電結(jié)晶﹕金屬原子沿金屬表面擴(kuò)散到結(jié)晶生長(zhǎng)點(diǎn)﹐以金屬原子態(tài)排列在晶格內(nèi)﹐形成鍍層。 </p> <p> 電鍍時(shí)﹐以上三個(gè)步驟是同時(shí)進(jìn)行的﹐但進(jìn)行的速度不同﹐速度**慢的一個(gè)被稱為整個(gè)沉積過(guò)程的控制性環(huán)節(jié)。不同步驟作為控制性環(huán)節(jié)﹐的電沉積結(jié)果是不一樣的。 </p><p> 15.定位器：一般使用在藥槽內(nèi)的方法有固定式(浸泡時(shí)使用)和調(diào)整式(選鍍或考慮電流分布時(shí)使用)，而使用材質(zhì)有耐酸堿和耐熱的塑膠，玻璃，陶瓷等。至于在藥槽之外的定位器則多半使用不銹鋼。 </p> <p> 16.陰陽(yáng)極：陰(陽(yáng))極導(dǎo)電電線規(guī)格為==比較大操作電流/4*(線數(shù))。如電流為100安培，導(dǎo)線兩條，則導(dǎo)線橫截面至少需要12.5平方毫米以上。陽(yáng)極有分溶解性陽(yáng)極和不溶性陽(yáng)極。溶解性陽(yáng)極是用在補(bǔ)充(普通金屬電鍍常見(jiàn))，而不溶性陽(yáng)極都做輔**極的用，如鍍鎳時(shí)，使用鎳金屬做溶解性陽(yáng)極，鈦籃為裝鎳金屬用，故為不溶性陽(yáng)極。在有些情況下，如鍍鉻，是采用鉛、鉛銻合金制成的不溶性陽(yáng)極，它只起傳遞電子、導(dǎo)通電流的作用。</p><div
