牡丹江電鍍銅鋼板

電鍍銅鋼板用于鑄模，鍍(du)(du)(du)(du)鎳，鍍(du)(du)(du)(du)鉻，鍍(du)(du)(du)(du)銀和(he)鍍(du)(du)(du)(du)金的打底，修復磨(mo)損部(bu)分(fen)，防止局(ju)部(bu)滲碳和(he)提(ti)高(gao)導電性(xing)。分(fen)為堿(jian)性(xing)鍍(du)(du)(du)(du)銅(tong)(tong)和(he)酸性(xing)鍍(du)(du)(du)(du)銅(tong)(tong)二(er)法。通常為了獲得(de)較薄(bo)的細致光滑的銅(tong)(tong)鍍(du)(du)(du)(du)層，將(jiang)表面(mian)除去(qu)油銹的鋼鐵等制件(jian)作(zuo)陰極，純銅(tong)(tong)板作(zuo)陽極，掛于含有氰(qing)化(hua)亞銅(tong)(tong)、氰(qing)化(hua)鈉和(he)碳酸鈉等成分(fen)的堿(jian)性(xing)電鍍(du)(du)(du)(du)液中(zhong)(zhong)，進行(xing)堿(jian)性(xing)（氰(qing)化(hua)物）鍍(du)(du)(du)(du)銅(tong)(tong)。為了獲得(de)較厚的銅(tong)(tong)鍍(du)(du)(du)(du)層，必須(xu)先(xian)將(jiang)鍍(du)(du)(du)(du)件(jian)進行(xing)堿(jian)性(xing)鍍(du)(du)(du)(du)銅(tong)(tong)，再(zai)置于含有硫(liu)酸銅(tong)(tong)、硫(liu)酸鎳和(he)硫(liu)酸等成分(fen)的電解液中(zhong)(zhong)，進行(xing)酸性(xing)鍍(du)(du)(du)(du)銅(tong)(tong)。此外，還有焦(jiao)磷酸鹽、酒石(shi)酸鹽、乙二(er)胺(an)等配制的無氰(qing)電解液。焦(jiao)磷酸鹽電解液已被(bei)廣(guang)泛采用。
