style="text-indent:25px">鍍銀的工藝流程是比較復(fù)雜的，銀金屬本身是比較貴重的金屬，不處理好的造成的浪費(fèi)也會(huì)加大廠家的生產(chǎn)加工成本。鍍銀基本的流程包括有電鍍除油、熱水冷水洗、化學(xué)除銹、二次水洗、**頂鍍銅、三次水洗、酸性光亮鍍銅、四次水洗、光亮鍍鎳、五次水洗、沖擊鍍銀、去離子水洗、鈍化、浸400有機(jī)膜，廣州醫(yī)用探測(cè)器前殼鍍銀工藝、烘干，廣州醫(yī)用探測(cè)器前殼鍍銀工藝、浸光亮漆保護(hù)膜、二次烘干、檢驗(yàn)質(zhì)檢。從這個(gè)工藝流程中不難看出水在其中的參與是多么的重要，所以電鍍中不僅需要對(duì)廢液進(jìn)行處理，廣州醫(yī)用探測(cè)器前殼鍍銀工藝，而且對(duì)于電鍍中的廢水進(jìn)行處理。尤其是當(dāng)無(wú)氰鍍銀不再采用堿性和表面活性都很強(qiáng)的**鉀后，可以在更寬的范圍選用表面活性劑；廣州醫(yī)用探測(cè)器前殼鍍銀工藝</p><div

鍍銀后是需要對(duì)銀層進(jìn)行一定的處理來(lái)防止其氧化變色的，下面介紹下一些常見(jiàn)的用來(lái)防止鍍銀層氧化變色的方法。使用硫|酸鹽鍍銀液鍍銀的在鍍膜后需要在干燥之前使用磷酸溶液進(jìn)行脫模處理，反復(fù)操作，脫模是為了防止日后發(fā)黃變色。鍍銀加工避免使用逆流漂洗，容易造成發(fā)霧現(xiàn)象。如果是銅基體鍍銀的話可以先預(yù)鍍一層銅，這樣既可以增加鍍層的結(jié)合力均勻性，有能阻止黃銅離子向銀層滲透。鍍銀后需要中和和鈍化處理，從而中和鍍銀過(guò)程中殘留的酸并且在鍍銀層身上形成一保護(hù)膜。鍍銀后要避免鍍膜后清洗不干凈，也要防止電流密度過(guò)高，再者就是要避免鍍液溫度過(guò)高。對(duì)于一些特殊的材料，都可以采用前述的兩次預(yù)鍍的方法，比較保險(xiǎn)。珠海手機(jī)攝像頭基座鍍銀廠家</p><p

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(huì)造成跟轉(zhuǎn)速低一樣的情況。滾桶眼孔徑是方便鍍液流動(dòng)，孔徑的大小是影響鍍液的流動(dòng)和電流通過(guò)的。鍍液成分對(duì)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。廣州醫(yī)用探測(cè)器前殼鍍銀工藝</p><p
