style="text-indent:25px">依據(jù)鍍銀物件的變色原理和各種因素對鍍銀物件變色速度的影響，能把防止鍍銀件變色的方法總結(jié)成這幾類：第一種是在物件表面進(jìn)行化學(xué)鈍化處理，使得銀層表面形成一層氧化物保護(hù)層，以此達(dá)到延緩變色的速度；第二種是銀表面涂上保護(hù)膜來屏蔽銀層表面和紫外線、氧氣、腐蝕物質(zhì)的接觸，來達(dá)到延緩銀層變色的目的；蕞后一種是改善銀色工藝條件，來提供鍍銀層本其本身的防變色能力。這是對鍍銀層目前采用比較主流的防變色（延緩變色）的處理方法。</p><p style="text-indent:25px">銀本身的性質(zhì)較為活潑，其在鍍液中的穩(wěn)定性能也是比較差的，容易引起鍍液分解。因?yàn)樵谠刂芷诶?，銀是屬于貴金屬中的一員，它很難與其他的金屬形成合金鍍層.鍍銀用的鍍液也是比較有限的,大都數(shù)使用的都是含有**物的堿性溶液,**物大家都明白是什么物質(zhì)了.鍍銀的性能特點(diǎn)包括有:鍍層應(yīng)呈銀白色,結(jié)晶細(xì)致平滑;與空氣接觸會逐漸氧化變色，遇硫會變黑;接觸電阻低，導(dǎo)電性能極好;導(dǎo)熱性能好;防粘結(jié)性強(qiáng);易焊接;具有優(yōu)良的反光特性;表面光潔銀亮，膜層均勻。鍍液一定要謹(jǐn)慎保管處理。這種預(yù)鍍過程由于時間很短，也被叫做閃鍍。</p><div

style="text-indent:25px">電鍍金屬材料的表面處理技術(shù)也可以稱為電化學(xué)法，它是利用電極反應(yīng)，然后在加工件的表面形成鍍層，方法包括有電鍍、氧化。另外，對于金屬材料或非金屬表面處理技術(shù)也稱為化學(xué)鍍膜方法，它是在無電流作用下，利用化學(xué)反應(yīng)相互作用，在加工件的表面形成鍍層，方法包括有化學(xué)轉(zhuǎn)化膜處理、化學(xué)鍍。材料表面處理之熱加工法，是在高溫條件下讓那個材料融化或擴(kuò)散，從而在加工件表面形成薄膜涂層，方法包括有熱浸鍍、熱噴涂、熱燙印、化學(xué)熱處理和堆焊等。除了這些外還有使用真空技術(shù)進(jìn)行表面處理的。國內(nèi)情況來看，大體上有硫代硫|酸鹽鍍銀、磺基水楊酸鍍銀、亞硫|酸鹽鍍銀、煙酸鍍銀和丁二酰亞胺鍍銀等類型。佛山醫(yī)用探測器前殼鍍銀廠家</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)速低的時候鍍層厚度變化大，分散能力也不太理想，但是達(dá)到一個額定值后，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。佛山醫(yī)用探測器前殼鍍銀廠家</p><p
