大慶電鍍銅鋼板

電鍍銅鋼板用于(yu)(yu)鑄模(mo)，鍍(du)鎳，鍍(du)鉻(ge)，鍍(du)銀和(he)鍍(du)金的(de)(de)打(da)底，修(xiu)復(fu)磨損部(bu)分(fen)，防止局部(bu)滲碳和(he)提高導(dao)電性(xing)(xing)。分(fen)為堿性(xing)(xing)鍍(du)銅(tong)(tong)(tong)和(he)酸(suan)(suan)(suan)性(xing)(xing)鍍(du)銅(tong)(tong)(tong)二(er)(er)法。通(tong)常為了獲得較薄的(de)(de)細致光滑的(de)(de)銅(tong)(tong)(tong)鍍(du)層(ceng)，將表(biao)面除去(qu)油銹的(de)(de)鋼鐵等制(zhi)件作陰極，純銅(tong)(tong)(tong)板作陽(yang)極，掛(gua)于(yu)(yu)含有氰(qing)化亞銅(tong)(tong)(tong)、氰(qing)化鈉和(he)碳酸(suan)(suan)(suan)鈉等成分(fen)的(de)(de)堿性(xing)(xing)電鍍(du)液中，進(jin)(jin)(jin)行(xing)(xing)堿性(xing)(xing)（氰(qing)化物）鍍(du)銅(tong)(tong)(tong)。為了獲得較厚的(de)(de)銅(tong)(tong)(tong)鍍(du)層(ceng)，必(bi)須先將鍍(du)件進(jin)(jin)(jin)行(xing)(xing)堿性(xing)(xing)鍍(du)銅(tong)(tong)(tong)，再置于(yu)(yu)含有硫(liu)酸(suan)(suan)(suan)銅(tong)(tong)(tong)、硫(liu)酸(suan)(suan)(suan)鎳和(he)硫(liu)酸(suan)(suan)(suan)等成分(fen)的(de)(de)電解(jie)液中，進(jin)(jin)(jin)行(xing)(xing)酸(suan)(suan)(suan)性(xing)(xing)鍍(du)銅(tong)(tong)(tong)。此外，還有焦(jiao)磷酸(suan)(suan)(suan)鹽(yan)(yan)、酒石(shi)酸(suan)(suan)(suan)鹽(yan)(yan)、乙二(er)(er)胺等配(pei)制(zhi)的(de)(de)無(wu)氰(qing)電解(jie)液。焦(jiao)磷酸(suan)(suan)(suan)鹽(yan)(yan)電解(jie)液已被廣泛采用。
