style="text-indent:25px">鍍鋅可以分為**物鍍鋅，氯化鉀鍍鋅，堿性鋅鹽鍍鋅，硫酸鹽鍍鋅等。電鍍鋅工藝影響因素：電流密度對(duì)鍍鋅產(chǎn)品的外觀和耐蝕都有重要的影響。電流密度越高，電鍍層的腐蝕電位越高，腐蝕速率降低，耐蝕性增強(qiáng)。體系鍍液是影響鍍鋅品質(zhì)好壞的另一個(gè)非常重要的因素，不同的體系要考慮濃度的配比，溫度，PH等。另外，伴隨材料發(fā)展出現(xiàn)一些新材料的鍍鋅方法，比如各種合金、納米結(jié)構(gòu)的鋅。所謂鋅合金，是指電鍍合金中以鋅為主要金屬，其含量要在51%以上(質(zhì)量百分?jǐn)?shù))。除此之外，還含有一種或幾種其他金屬。例如:鋅鎳合金(含鎳l0%左右)、鋅鐵合金(分高鐵合金和低鐵合金，前者質(zhì)量百分?jǐn)?shù)為7%以上，上海鋅鎳合金掛鍍哪里質(zhì)量好，上海鋅鎳合金掛鍍哪里質(zhì)量好，而后者為<1%)、鋅銅合金(俗稱白銅，上海鋅鎳合金掛鍍哪里質(zhì)量好，含銅質(zhì)量百分?jǐn)?shù)為15%~25%)。電鍍鋅鎳合金分高鎳和低鎳兩種。上海鋅鎳合金掛鍍哪里質(zhì)量好</p><div
