13.泵過濾機(jī)：一般分臥式泵和立式泵，其規(guī)格以HP馬力來區(qū)分，馬力越大，其流量也越大，過濾機(jī)濾心常用規(guī)格為1μ，5μ，10μ，μ數(shù)越小可過濾的顆粒越小，過濾的效果也就越好。一般建議金槽，鈀鎳槽使用1μ，上海電鍍?cè)O(shè)備價(jià)格，而其他的使用5μ濾心，并且每周定期檢查。過濾時(shí)間越長，效果越好，如能24小時(shí)過濾比較好，上海電鍍?cè)O(shè)備價(jià)格。

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，上海電鍍?cè)O(shè)備價(jià)格，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%。電解液中的鉻離子濃度，需依靠定期地向鍍液中加入鉻化合物來維持。上海電鍍?cè)O(shè)備價(jià)格</p><div

下圖是電鍍裝置示意圖﹐被鍍的零件為陰極﹐與直流電源的負(fù)極相連﹐金屬陽極與直流電源的正極聯(lián)結(jié)﹐陽極與陰均浸入鍍液中。當(dāng)在陰陽兩極間施加一定電位時(shí)﹐則在陰極發(fā)生如下反應(yīng)﹕從鍍液內(nèi)部擴(kuò)散到電極和鍍液界面的金屬離子Mn+從陰極上獲得n個(gè)電子﹐還原成金屬M(fèi)。 </p> <p> <br /> </p> <p> 另一方面﹐在陽極則發(fā)生與陰極完全相反的反應(yīng)﹐即陽極界面上發(fā)生金屬M(fèi)的溶解﹐釋放n個(gè)電子生成金屬離子M n+。 </p> <p> 2.法拉第定律 </p> <p> <br /> </p> <p> 電流通過鍍液時(shí)﹐電解質(zhì)溶液發(fā)生電解反應(yīng)﹐陰極上不斷有金屬析出﹐陽極金屬不斷溶解。因此﹐金屬的析出(或溶解)量必定與通過的電荷有關(guān)。根據(jù)大量實(shí)驗(yàn)結(jié)果﹐法拉第建立了析出(或溶解)的物質(zhì)與電荷之間的關(guān)系的定律。上海電鍍?cè)O(shè)備價(jià)格所以，又把電流-電位曲線稱為極化曲線。</p><div

電鍍電源線和電極很少有電鍍企業(yè)納入管理，可以說是個(gè)管理的盲點(diǎn)。很多企業(yè)的電源線過電截面積是不夠的，因此可以發(fā)現(xiàn)無論是一次線還是二次線，均有發(fā)熱，甚至發(fā)燙現(xiàn)象，這是浪費(fèi)電力而又不安全的。因此一定要保證導(dǎo)電線能有工作需要的比較大電流強(qiáng)度的導(dǎo)電能力，并以電源線不發(fā)熱為基本要求。 </p> <p> 同時(shí)要保持所有電源接點(diǎn)、接頭的良好導(dǎo)通狀態(tài)。有些電鍍廠，導(dǎo)線截面是夠了，但是某些接點(diǎn)都嚴(yán)重腐蝕，導(dǎo)電能力下降，成為一個(gè)電阻器，這時(shí)接點(diǎn)發(fā)熱，燒壞的就時(shí)有發(fā)生。 </p><p> 電鍍技術(shù)又稱為電沉積,是在材料表面獲得金屬鍍層的主要方法之一。是在直流電場的作用下，在電解質(zhì)溶液（鍍液）中由陽極和陰極構(gòu)成回路，使溶液中的金屬離子沉積到陰極鍍件表面上的過程; 電流效率：用于沉積金屬的電量占總電量的比稱為電鍍的電流效率。 </p> <p> <br /> </p> <p> 分散能力：鍍液的分散能力是指一定的電解條件下使沉積金屬在陰極零件表面上分布均勻的能力。 </p> <p> <br /> </p> <p> 合金電鍍：兩種或兩種以上金屬離子在陰極上共沉積形成均勻細(xì)致鍍層的過程叫做合金電鍍（一般而言其**小組分應(yīng)大于1%）。 </p> <p> <br /> </p> <p> 整平能力：整平能力（即微觀分散能力）是指在金屬表面上形成鍍層時(shí)，鍍液所具有的能使鍍層的微觀輪廓比基體表面更平滑的能力。它表達(dá)了基體金屬的粗糙度比較小，波穴的深度小于0.5mm，波峰與波谷的距離很小的表面上鍍層分布的均勻性。陰極：被鍍物，指各種接插件端子。</p><div style="width:100%;text-align: center;"><img

鍍液中的pH值可以影響氫的放電電位﹐堿性夾雜物的沉淀﹐還可以影響絡(luò)合物或水化物的組成以及添加劑的吸附程度。但是﹐對(duì)各種因素的影響程度一般不可預(yù)見。比較好的pH值往往要通過試驗(yàn)決定。在含有絡(luò)合劑離子的鍍液中﹐pH值可能影響存在的的各種絡(luò)合物的平衡﹐<而必須根據(jù)濃度來考慮。電鍍過程中﹐若pH值增大﹐則陰極效率比陽極效率高﹐pH值減少則反之。通過加入緩沖劑可以將pH值穩(wěn)定在一定范圍。
