大連電鍍銅鋼板

電鍍銅鋼板用(yong)于(yu)鑄模，鍍(du)(du)鎳，鍍(du)(du)鉻，鍍(du)(du)銀和鍍(du)(du)金的(de)(de)打底，修復磨(mo)損部(bu)分(fen)，防(fang)止局部(bu)滲碳和提高導(dao)電性(xing)(xing)。分(fen)為堿性(xing)(xing)鍍(du)(du)銅(tong)(tong)(tong)(tong)和酸(suan)性(xing)(xing)鍍(du)(du)銅(tong)(tong)(tong)(tong)二法(fa)。通常為了獲得較薄的(de)(de)細致光滑的(de)(de)銅(tong)(tong)(tong)(tong)鍍(du)(du)層，將表(biao)面除(chu)去(qu)油銹的(de)(de)鋼鐵等(deng)制(zhi)(zhi)件作陰極，純銅(tong)(tong)(tong)(tong)板作陽(yang)極，掛于(yu)含有(you)氰(qing)化亞(ya)銅(tong)(tong)(tong)(tong)、氰(qing)化鈉和碳酸(suan)鈉等(deng)成分(fen)的(de)(de)堿性(xing)(xing)電鍍(du)(du)液(ye)(ye)中(zhong)，進行(xing)堿性(xing)(xing)（氰(qing)化物）鍍(du)(du)銅(tong)(tong)(tong)(tong)。為了獲得較厚的(de)(de)銅(tong)(tong)(tong)(tong)鍍(du)(du)層，必須先將鍍(du)(du)件進行(xing)堿性(xing)(xing)鍍(du)(du)銅(tong)(tong)(tong)(tong)，再置(zhi)于(yu)含有(you)硫(liu)(liu)酸(suan)銅(tong)(tong)(tong)(tong)、硫(liu)(liu)酸(suan)鎳和硫(liu)(liu)酸(suan)等(deng)成分(fen)的(de)(de)電解液(ye)(ye)中(zhong)，進行(xing)酸(suan)性(xing)(xing)鍍(du)(du)銅(tong)(tong)(tong)(tong)。此外，還有(you)焦磷(lin)酸(suan)鹽、酒石(shi)酸(suan)鹽、乙(yi)二胺等(deng)配制(zhi)(zhi)的(de)(de)無氰(qing)電解液(ye)(ye)。焦磷(lin)酸(suan)鹽電解液(ye)(ye)已被廣泛采用(yong)。
