液相傳質(zhì)﹕鍍液中的水化金屬離子或絡離子從溶液內(nèi)部向極界面遷移﹐到達陰極的雙電層溶液一側。 </p> <p> 電化學反應﹕水化金屬離子或絡離子通過雙電層﹐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﹐對流和擴散，紹興龍門電鍍設備，紹興龍門電鍍設備。 </p> <p> 電結晶﹕金屬原子沿金屬表面擴散到結晶生長點﹐以金屬原子態(tài)排列在晶格內(nèi)﹐形成鍍層。 </p> <p> 電鍍時﹐以上三個步驟是同時進行的﹐但進行的速度不同﹐速度**慢的一個被稱為整個沉積過程的控制性環(huán)節(jié)，紹興龍門電鍍設備。不同步驟作為控制性環(huán)節(jié)﹐的電沉積結果是不一樣的。此外還可提高溶液的導電性、促進陽極溶解、提高陰極電流效率、減少、降低鍍層內(nèi)應力等效果。紹興龍門電鍍設備</p><div style="width:100%;text-align:

鍍色廠鍍鉻處理技術是日常的生活應用中應用的很，如鍍色廠金屬家具的框架和汽車內(nèi)飾件鏡面光潔度。工業(yè)中較厚的鍍烙一般稱為硬鉻，通常是應用于工業(yè)設備，以減少摩擦和磨損，并恢復設備，經(jīng)歷了穿的尺寸。 </p> <p> 如今的鍍烙主要有兩種類型的應用：一種是工業(yè)應用；另一種是裝飾性應用。工業(yè)鍍鉻也被稱為硬鉻或鉻工程。 </p> <p> 有兩種類型的工業(yè)鍍鉻的解決方案：一種是六價鉻浴，其主要成分是鉻酐和三價鉻浴，其主要成分是鉻或氯化鉻。另一種是三價鉻浴場尚未普及，由于限制有關的顏色，脆性，電鍍厚度。 </p> <p> 而用于裝飾的鍍烙，比較好的組合就是將鉻和鎳的防腐蝕提供了比較好保護。這將有一個鏡面，將只能像表面上完成你把你的鍍鉻前把好。 </p> <p> 鍍硬鉻，厚度為需要采取的摩擦系數(shù)極低鉻優(yōu)勢，或穿積累功能的目的。紹興龍門電鍍設備鍍錫鉛：增進焊接能力，快被其他替物取代（因含鉛現(xiàn)大部分改為鍍亮錫及霧錫）。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

<p> <br /> </p> <p> (2)濃差極化 </p> <p> <br /> </p> <p> 由于鄰近電極表液層的濃度與溶液主體的濃度發(fā)生差異而產(chǎn)生的極化稱濃差極化﹐這是由于溶液中離子擴散速度小于電子運動造成的。 </p> <p> <br /> </p> <p> 第四節(jié) 金屬的電積過程 </p> <p> <br /> </p> <p> 電鍍過程是鍍液中的金屬離子在外電場的作用下﹐經(jīng)電極反應還原成金屬原子并在陰極上進行金屬沉積的過程。下圖(1-2)是電沉積過程示意圖﹐完成電沉積過程必須經(jīng)過以下三個步驟﹕ </p> <p> <br /> </p> <p> 液相傳質(zhì)﹕鍍液中的水化金屬離子或絡離子從溶液內(nèi)部向極界面遷移﹐到達陰極的雙電層溶液一側。 </p><p> 首先電鍍液有六個要素：主鹽、附加鹽、絡合劑、緩沖劑、陽極活化劑和添加劑。 </p> <p> <br /> </p> <p> 電鍍原理包含四個方面：電鍍液、電鍍反應、電極與反應原理、金屬的電沉積過程。 </p> <p> <br /> </p> <p> 電鍍反應中的電化學反應：下圖是電鍍裝置示意圖，被鍍的零件為陰極，與直流電源的負極相連，金屬陽極與直流電源的正極聯(lián)結，陽極與陰均浸入鍍液中。當在陰陽兩極間施加一定電位時，則在陰極發(fā)生如下反應：從鍍液內(nèi)部擴散到電極和鍍液界面的金屬離子Mn+從陰極上獲得n個電子，還原成金屬M。另一方面，在陽極則發(fā)生與陰極完全相反的反應，即陽極界面上發(fā)生金屬M的溶解，釋放n個電子生成金屬離子Mn+。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，能絡合主鹽中金屬離子形成絡合物的絡合劑。</p><div

電源線、電極的管理 </p> <p> 電鍍電源線和電極很少有電鍍企業(yè)納入管理，可以說是個管理的盲點。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，這是浪費電力而又不安全的。因此一定要保證導電線能有工作需要的比較大電流強度的導電能力，并以電源線不發(fā)熱為基本要求。 </p> <p> 同時要保持所有電源接點、接頭的良好導通狀態(tài)。有些電鍍廠，導線截面是夠了，但是某些接點都嚴重腐蝕，導電能力下降，成為一個電阻器，這時接點發(fā)熱，燒壞的就時有發(fā)生。電鍍的目的是在基材上鍍上金屬鍍層，改變基材表面性質(zhì)或尺寸。天津電鍍設備便宜</p><p

像加熱器這類輔助設備，有時是被納入低值易耗品管理。像電燈泡一樣，隨壞隨換。是不是加熱器產(chǎn)品質(zhì)量有問題?這當然是有的，有些加熱器產(chǎn)品確實存在質(zhì)量問題。不僅壽命短，而且還發(fā)生漏電等問題。這在采購時就要加以杜絕。 </p> <p> 使用中的損壞是大量的，**常見是超時升溫和液位不足導致的局部空燒，使結點處過熱而損壞。而使用不當也就是管理不當?shù)慕Y果。 </p> <p> 過濾機的損壞也很大程度上是使用不當引起的，當然也有產(chǎn)品質(zhì)量和設計壽命的問題。但是即使是進口的高技術設備，使用和管理不當，其壽命也會下降。所以加強對輔助設備的管理，要像對主要設備一樣，建立考核制度。在規(guī)定的使用壽命內(nèi)出現(xiàn)損壞的要分析原因進行相應的問責制。這樣一來，就可以提高輔助設備的使用效率和壽命，從而提高電鍍生產(chǎn)管理的整體水平。紹興龍門電鍍設備</p><p
