沈陽電鍍銅鋼板

電鍍銅鋼板用(yong)于鑄模，鍍(du)(du)(du)(du)鎳(nie)，鍍(du)(du)(du)(du)鉻，鍍(du)(du)(du)(du)銀(yin)和(he)鍍(du)(du)(du)(du)金的(de)打底，修復磨損部分(fen)，防止局部滲碳和(he)提高導電(dian)性(xing)(xing)(xing)。分(fen)為(wei)堿(jian)性(xing)(xing)(xing)鍍(du)(du)(du)(du)銅(tong)(tong)(tong)和(he)酸(suan)(suan)性(xing)(xing)(xing)鍍(du)(du)(du)(du)銅(tong)(tong)(tong)二法。通常(chang)為(wei)了獲得較薄(bo)的(de)細致(zhi)光滑的(de)銅(tong)(tong)(tong)鍍(du)(du)(du)(du)層，將表面除去油(you)銹的(de)鋼(gang)鐵(tie)等制件作陰極，純銅(tong)(tong)(tong)板(ban)作陽極，掛(gua)于含有氰化(hua)亞銅(tong)(tong)(tong)、氰化(hua)鈉(na)和(he)碳酸(suan)(suan)鈉(na)等成分(fen)的(de)堿(jian)性(xing)(xing)(xing)電(dian)鍍(du)(du)(du)(du)液中，進(jin)行(xing)堿(jian)性(xing)(xing)(xing)（氰化(hua)物）鍍(du)(du)(du)(du)銅(tong)(tong)(tong)。為(wei)了獲得較厚(hou)的(de)銅(tong)(tong)(tong)鍍(du)(du)(du)(du)層，必須先將鍍(du)(du)(du)(du)件進(jin)行(xing)堿(jian)性(xing)(xing)(xing)鍍(du)(du)(du)(du)銅(tong)(tong)(tong)，再置于含有硫酸(suan)(suan)銅(tong)(tong)(tong)、硫酸(suan)(suan)鎳(nie)和(he)硫酸(suan)(suan)等成分(fen)的(de)電(dian)解液中，進(jin)行(xing)酸(suan)(suan)性(xing)(xing)(xing)鍍(du)(du)(du)(du)銅(tong)(tong)(tong)。此外，還有焦磷酸(suan)(suan)鹽、酒石酸(suan)(suan)鹽、乙(yi)二胺等配制的(de)無氰電(dian)解液。焦磷酸(suan)(suan)鹽電(dian)解液已被廣泛采用(yong)。
