鞍山電鍍銅鋼板

電鍍銅鋼板用(yong)于(yu)鑄模，鍍(du)(du)鎳，鍍(du)(du)鉻(ge)，鍍(du)(du)銀和(he)鍍(du)(du)金的打底，修(xiu)復磨損部分(fen)，防止局部滲碳和(he)提高導電性(xing)。分(fen)為堿(jian)性(xing)鍍(du)(du)銅(tong)(tong)(tong)和(he)酸性(xing)鍍(du)(du)銅(tong)(tong)(tong)二(er)法。通常(chang)為了(le)獲得較薄的細致光滑(hua)的銅(tong)(tong)(tong)鍍(du)(du)層，將表面除去油銹(xiu)的鋼(gang)鐵等(deng)(deng)制件作陰極，純銅(tong)(tong)(tong)板作陽(yang)極，掛(gua)于(yu)含有氰化(hua)(hua)亞銅(tong)(tong)(tong)、氰化(hua)(hua)鈉(na)和(he)碳酸鈉(na)等(deng)(deng)成分(fen)的堿(jian)性(xing)電鍍(du)(du)液(ye)中(zhong)，進行(xing)堿(jian)性(xing)（氰化(hua)(hua)物）鍍(du)(du)銅(tong)(tong)(tong)。為了(le)獲得較厚的銅(tong)(tong)(tong)鍍(du)(du)層，必須(xu)先將鍍(du)(du)件進行(xing)堿(jian)性(xing)鍍(du)(du)銅(tong)(tong)(tong)，再置于(yu)含有硫(liu)(liu)酸銅(tong)(tong)(tong)、硫(liu)(liu)酸鎳和(he)硫(liu)(liu)酸等(deng)(deng)成分(fen)的電解液(ye)中(zhong)，進行(xing)酸性(xing)鍍(du)(du)銅(tong)(tong)(tong)。此外，還有焦(jiao)磷(lin)酸鹽、酒石酸鹽、乙(yi)二(er)胺等(deng)(deng)配制的無氰電解液(ye)。焦(jiao)磷(lin)酸鹽電解液(ye)已被廣泛采用(yong)。
