style="text-indent:25px">鍍鋅鎳合金要注意這幾個要點：要注意的就是基材的前處理，這一點是非常重要的，但是有時候卻可能忽略。電鍍基材表面的結(jié)合力、導(dǎo)電性能，平整度，是否有殘留物，這些都是要考慮的，往往會有許多人忽視到這一點，導(dǎo)致電鍍出來的效果極差。以比較常見的銅材電鍍?yōu)槔~是非常好的電鍍鋅鎳合金的基材，但是也需要注意，銅的表面是否可行，比如是否氧化，是否有油污污漬殘留，一些污漬肉眼甚至無法察覺。如果是氧化嚴(yán)重，可以先做活化，如果有殘留污漬，那么就要先進(jìn)行清洗前處理，清洗干凈后再進(jìn)行電鍍，否則會造成鍍層不穩(wěn)定以及變色的結(jié)果。</p><p style="text-indent:25px">電鍍鋅鎳合金工藝：電鍍鋅鎳合金是利用電解的原理將導(dǎo)電體鋪上一層金屬的方法。除了導(dǎo)電體以外，電鍍亦可用于經(jīng)過特殊處理的塑膠上。電鍍的過程基本如下：把鍍上去的金屬接在陽極，或者把待鍍金屬的可溶性鹽添加在槽液中。要被電鍍的物件接在陰極。陰陽極以鍍上去的金屬的正離子組成的電解質(zhì)溶液相連。通以直流電的電源后，陽極的金屬會釋放電子，溶液中的正離子則在陰極還原（得到電子）成原子并積聚在陰極表層。電鍍后被電鍍物件的美觀性和電流密度大小有關(guān)系，在可操作電流密度范圍內(nèi)，電流密度越小，被電鍍的物件便會越美觀；反之則會出現(xiàn)一些不平整的形狀。電流密度指一定面積上的電流分布，常用的電流密度單位是安培每平方分米[ASD]和安培每平方英尺。一般情況下，電鍍槽液呈酸性，能夠腐蝕溶解陰極鍍層金屬，當(dāng)電流密度太小時（小于5ASF時），由于酸性槽液的溶解，鍍層金屬會呈現(xiàn)疏松和無光澤的外觀。電鍍的主要用途包括防止金屬氧化（如銹蝕）以及進(jìn)行裝飾。不少硬幣的外層亦為電鍍。電鍍產(chǎn)生的污水（如失去效用的電解質(zhì)）是水污染的重要來源。鋅鎳合金具有更好的耐磨性。</p><div

style="text-indent:25px">電鍍鋅目的是為了防止鋼鐵類物體被腐蝕，提高鋼鐵的耐蝕性及使用壽命，同時也使產(chǎn)品增加裝飾性的外觀，鋼鐵隨著時間的增長會被風(fēng)化，水或泥土腐蝕。國內(nèi)每年被腐蝕的鋼鐵差不多占整個鋼鐵量的十分之一，所以，為了保護(hù)鋼鐵或其零件的使用壽命，一般都采用電鍍鋅來將鋼鐵加工處理。由于鋅在干燥空氣中不易變化，而且在潮濕的環(huán)境下更能產(chǎn)生一種堿式碳酸鋅薄膜，這種薄膜就能保護(hù)好內(nèi)部零件而不被腐蝕損壞，即使鋅層被某種因素破壞的情況下，鋅和鋼經(jīng)過一段時間結(jié)合會形成一種微電池，而使鋼基體成為陰極而受到保護(hù)?？偨Y(jié)電鍍鋅有以下特點：1、抗腐蝕性好，結(jié)合細(xì)致均勻，不易被腐蝕性氣體或液體進(jìn)入內(nèi)部。2、由于鋅層比較純，無論在酸或堿環(huán)境底下都不易被腐蝕。長時間有效的保護(hù)鋼體。3、經(jīng)鉻酸鈍化后形成各種顏色使用，可根據(jù)客戶喜愛挑選，鍍鋅美觀大方，具有裝飾性。4、鋅鍍層具有良好的延展性，在進(jìn)行各種折彎，搬運撞擊等都不會輕易掉落。鋅合金的研究與應(yīng)用對提高防護(hù)層質(zhì)量，減薄鍍層，節(jié)約金屬，減少污染和降低成本等有重要意義。常見的電鍍鍍鋅鎳合金</p><p style="text-indent:25px">電鍍鋅鎳合金的熔點也高，耐高溫性很好。表面處理鋅鎳合金生產(chǎn)廠家</p><p style="text-indent:25px">眾所周知，陰極上荷負(fù)電，但要在陰極上放電的粒子可能荷正電、負(fù)電或呈電中性，當(dāng)放電粒子帶負(fù)電時，則存在電極與離子間的排斥作用，此時可加入乳化劑(如季銨鹽)，使負(fù)離子與季銨鹽之間生成離子對，從而降低負(fù)離子與陰極間的斥力作用，加速負(fù)離子的電極反應(yīng)。另外，在合金的電沉積過程中，添加季銨鹽等陽離子型表面活性劑能加速荷負(fù)電的配離子中的陽離子的沉積，阻礙荷正電的配離子中陽離子沉積，從而增大鍍層中從荷負(fù)電的配離子還原所得產(chǎn)物與從荷正電的配離子還原所得產(chǎn)物的比例，控制鍍層組成。利用該方法能有效去除電鍍鋅鎳合金過程中滲入基體金屬的氫，減少氫脆性的發(fā)生，而且可在合金鍍層表面生成防護(hù)性能優(yōu)良的鈍化膜，同時，本發(fā)明工藝方法簡單、生產(chǎn)成本低廉。表面處理鋅鎳合金生產(chǎn)廠家</p><p
