由于電鍍液需要在一定溫度下工作，因此要為鍍槽配備加溫設(shè)備。比如鍍光亮鎳需要鍍液溫度保持在50℃，青海電鍍?cè)O(shè)備烘道，鍍鉻需要的溫度是50～60℃，而酸性光亮鍍銅或光亮鍍銀又要求溫度在30℃以內(nèi)。這樣，青海電鍍?cè)O(shè)備烘道，對(duì)這些工藝要求需要用熱交換設(shè)備加以滿足，青海電鍍?cè)O(shè)備烘道。對(duì)于加溫一般采用直持加熱方式。電鍍能增強(qiáng)金屬的抗腐蝕性增加硬度、防止磨耗、提高導(dǎo)電性、光滑性、耐熱性和表面美觀。青海電鍍?cè)O(shè)備烘道</p><div

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(duì)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(shí)﹐測(cè)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(guò)電極時(shí)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。 </p><p> 電鍍時(shí)的表面狀況和加工要求，選擇其中適當(dāng)?shù)膸讉€(gè)步驟，對(duì)零件表面進(jìn)行必要的修整加工，使零件具有平整光潔的表面，這是能否獲得質(zhì)量鍍層的重要環(huán)節(jié)。鍍前處理工藝中，所用的主要設(shè)備有磨、拋光機(jī)、刷光機(jī)、噴砂機(jī)、滾光機(jī)和各類固定槽。電鍍處理是整個(gè)生產(chǎn)過(guò)程中的主要工藝。根據(jù)零件的要求，有針對(duì)性選擇某一種或幾種單金屬或合金電鍍工藝對(duì)零件進(jìn)行電鍍或浸鍍等加工，以達(dá)到防蝕、耐磨和美觀的目的。電鍍處理過(guò)程中所用的設(shè)備主要有各類固定槽、滾鍍槽、掛具、吊籃等。鍍后處理是對(duì)零件進(jìn)行拋光、出光、鈍化、著色、干燥、封閉、去氫等工作，根據(jù)需要選用其中一種或數(shù)種工序使零件符合質(zhì)量要求。鍍后處理常用設(shè)備主要有磨、拋光機(jī)、各類固定槽等。電鍍產(chǎn)生的污水是水污染的重要來(lái)源。電鍍工藝已經(jīng)被普遍的使用在半導(dǎo)體及微電子部件引線框架的工藝。</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(shuō)是個(gè)管理的盲點(diǎn)。很多企業(yè)的電源線過(guò)電截面積是不夠的，因此可以發(fā)現(xiàn)無(wú)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。除了導(dǎo)電體以外，電鍍亦可用于經(jīng)過(guò)特殊處理的塑膠上。青海電鍍?cè)O(shè)備烘道</p><p style="text-indent:25px">陰極：被鍍物，指各種接插件端子。青海電鍍?cè)O(shè)備烘道</p><p> 第二節(jié) 電鍍反應(yīng) </p> <p> <br /> </p> <p> 1.電化學(xué)反應(yīng) </p> <p> <br /> </p> <p> 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(yáng)極與直流電源的正極聯(lián)結(jié)﹐陽(yáng)極與陰均浸入鍍液中。當(dāng)在陰陽(yáng)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(yáng)極則發(fā)生與陰極完全相反的反應(yīng)﹐即陽(yáng)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(guò)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(yáng)極金屬不斷溶解。因此﹐金屬的析出(或溶解)量必定與通過(guò)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。青海電鍍?cè)O(shè)備烘道</p><p
