style="text-indent:25px">鍍銀工藝可以分為滾鍍銀和掛鍍銀。以滾鍍銀使用的滾鍍方式為，影響該工藝的因素包括有轉(zhuǎn)速印象、滾桶眼孔徑影響、鍍液成分影響和電流強(qiáng)度影響。滾鍍的轉(zhuǎn)速影響，轉(zhuǎn)速低的時(shí)候鍍層厚度變化大，分散能力也不太理想，但是達(dá)到一個(gè)額定值后，繼續(xù)增加轉(zhuǎn)速則會造成跟轉(zhuǎn)速低一樣的情況。滾桶眼孔徑是方便鍍液流動，孔徑的大小是影響鍍液的流動和電流通過的。鍍液成分對滾鍍鍍層的厚度和分散能力也是有比較大的影響的。電流強(qiáng)度的增加，鍍層厚度的變化幅度增大，鍍層的均勻性下降。佛山柜員機(jī)控制面板鍍銀廠商目前無氰鍍銀的努力還主要是在尋求合適的電鍍工藝配方上。</p><div

style="text-indent:25px">使用**物鍍銀在工藝施工過程中常會出現(xiàn)一些問題，下面羅列下出現(xiàn)的問題有：鍍銀層結(jié)晶比較粗糙，容易出現(xiàn)放黃現(xiàn)象，電鍍過程中陽極容易出現(xiàn)鈍化的現(xiàn)象。鍍銀中銀離子沉積速度緩慢，加工件（陰極）成膜效率低下且陽極溶解速度太快。鍍出來的銀層會出現(xiàn)發(fā)暗黑色斑點(diǎn)的情況，陽極表面會出現(xiàn)暗灰色的情況。鍍出來的銀層比較粗糙并且是灰白色的或者鍍層表面有黑色條紋。鍍出來的銀層出現(xiàn)起泡脫落的情況，結(jié)合力不太好。電鍍時(shí)電流密度和電鍍時(shí)間正常，但是鍍出來的銀層厚度不足或者不均勻。滾鍍時(shí)零件粗糙，鍍層呈橘皮狀。鍍銀中出現(xiàn)這些問題，都是與電鍍過程中相關(guān)的操作不當(dāng)造成的。</p><p style="text-indent:25px">電鍍絕不能等同于說是鍍金鍍銀，電鍍它是使用電解原理在某些金屬外表上鍍上薄膜在其他金屬或合金的過程，屬于材料表面處理的電化學(xué)處理概念。經(jīng)過電鍍的金屬材料其外表附著一層金屬膜，用來防止金屬修飾，提高耐磨性，導(dǎo)電性，反光性和裝飾作用的。而鍍金鍍銀則是具體的一種鍍種方式，以鍍金為例，它通常是用來裝飾用的，金對于目前人類社會而言都是具有舉足輕重的意義，所以常使用鍍金裝飾其他物品，另外對于電子元器件中也會使用到鍍金工藝來提高電子內(nèi)部的導(dǎo)電和傳遞信息的作用。如果采用物理方法能夠改善鍍層性能，將是蕞好的辦法，這對于環(huán)境保護(hù)有十分重要的意義；</p><div

style="text-indent:25px">鍍銀過程并非一次性完成的，會先經(jīng)過預(yù)鍍銀工序，預(yù)鍍銀能防止工件直接進(jìn)如銀槽銅與銀一字置換以及銀層結(jié)合力。預(yù)鍍銀的原理是鍍液中采用低主鹽高絡(luò)合物組成，不僅能有效降低置換反反應(yīng)的速度，而且能讓鍍液有較高的絡(luò)合度從而提高陰極化，讓鍍層或者一層結(jié)晶致密且絡(luò)合度良好的過渡層。借助化學(xué)反應(yīng)原理，在電的作用下，銀離子會在工件上得到電子而生成銀單質(zhì)，從而沉積到工件表面上，而不溶性的陽極只會做析氧返傭。鍍銀中使用的鍍液主要是由**銀鉀、**鉀配置而成的。加上帶電下槽，這樣在極短的時(shí)間內(nèi)(一般是30秒～l分鐘)；佛山柜員機(jī)控制面板鍍銀廠商</p><p
