style="text-indent:25px">鍍鋅是指在金屬、合金或者其它材料的表面鍍一層鋅，可以起到美觀、防銹等作用的表面處理技術(shù)。主要采用的方法是熱鍍鋅。鋅易溶于酸，也能溶于堿，故稱它為兩性金屬。鋅在干燥的空氣中幾乎不發(fā)生變化。在潮濕的空氣中，鋅表面會生成致密的堿式碳酸鋅膜。在含二氧化硫、硫化氫以及海洋性氣氛中，鋅的耐蝕性較差，尤其在高溫高濕含有機酸的氣氛里，鋅鍍層極易被腐蝕。鋅的標準電極電位為-0.76V，對鋼鐵基體來說，鋅鍍層屬于陽極性鍍層，它主要用于防止鋼鐵的腐蝕，其防護性能的優(yōu)劣與鍍層厚度關(guān)系甚大。鋅鍍層經(jīng)鈍化處理、染色或涂覆護光劑后，能提高其防護性和裝飾性。</p><p style="text-indent:25px">硫酸鹽鋅鎳合金的應(yīng)用一般都是為了防腐蝕。電鍍對鍍層外觀、光亮性和整平性沒有過高要求的產(chǎn)品，其主要的特點是：鍍液成分簡單，工藝穩(wěn)定，使用維護調(diào)整是容易，對設(shè)備腐蝕性小，使用電流密度高，陰極電流效率高，成本較低，生產(chǎn)效率高。缺點是，分散覆蓋能力差，整平性差，防腐蝕性相對較差。因此只適合鋼板及鋼帶等形狀簡單的工件生產(chǎn)。隨著社會的不斷進步，堿性鋅酸鹽鍍鋅光亮劑的開發(fā)及應(yīng)用，在堿性鋅酸鹽鍍鋅電流效率及沉積速度不斷改善的情況下，堿性鋅酸鹽體系的合金鍍液的電流效率和沉積速度都有了飛速的發(fā)展與進步，這個也奠定了其應(yīng)用的普遍性與推廣性。鍍鋅鎳合金用于增加導(dǎo)電率、反光性和美觀。</p><div

style="text-indent:25px">鋅鎳合金電鍍工藝，生產(chǎn)時首先要控制好鍍液的鋅、鎳離子濃度，即將Ni2+/(Zn2++Ni2+)控制為0.16，以確保鍍層中的鎳含量適當，較好的外觀和優(yōu)異的耐蝕性能。鍍液中Ni2+濃度越高，鍍層中的Ni含量越高，但Ni含量太高時，鍍層不易鈍化，生產(chǎn)成本也相應(yīng)提高。生產(chǎn)中要勤加少加鎳補充劑，及時分析鋅離子的濃度。其次，要控制鍍液的溫度和pH值。隨鍍液溫度的升高，鍍層中的Ni含量升高，因為陰極極化降低，金屬離子的擴散和遷移速度提高，增加了金屬離子在陰極擴散層中的濃度，提高了陰極電流效率;溫度過高，有機添加劑容易分解，影響配位劑、光亮劑的效果，進而影響Ni的沉積，使鍍層中的Ni含量下降，鍍層外觀也變得較差。在電鍍鋅中鍍層發(fā)暗或色澤不均勻，說明有金屬污染。寧波閥塊鍍鋅鎳哪里有</p><p style="text-indent:25px">電鍍鋅采用的防腐工藝對于基體材料等都有嚴格的要求。浦東新區(qū)集成閥塊鍍鋅鎳合金廠家</p><p style="text-indent:25px">電鍍鋅采用的防腐工藝對于基體材料等都有嚴格的要求。鍍層大多是單一金屬或合金，如鈦靶、鋅、鎘、金或黃銅、青銅等；也有彌散層，如鎳-碳化硅、鎳-氟化石墨等；還有覆合層，如鋼上的銅-鎳-鉻層、鋼上的銀-銦層等。電鍍的基體材料除鐵基的鑄鐵、鋼和不銹鋼外，還有非鐵金屬，如ABS塑料、聚丙烯、聚砜和酚醛塑料，但塑料電鍍前，必須經(jīng)過特殊的活化和敏化處理。電鍍鋅鎳合金的鍍層很容易拋光，并且有很強的反光能力和良好的導(dǎo)熱、導(dǎo)電、焊接性能。浦東新區(qū)集成閥塊鍍鋅鎳合金廠家</p></p><br
