電鍍銅鋼板中心

電鍍銅鋼板用(yong)(yong)于(yu)鑄模，鍍(du)(du)(du)鎳(nie)，鍍(du)(du)(du)鉻，鍍(du)(du)(du)銀和鍍(du)(du)(du)金的打底(di)，修復磨損部(bu)分，防止局部(bu)滲碳和提高(gao)導電性(xing)(xing)(xing)(xing)。分為(wei)(wei)(wei)堿性(xing)(xing)(xing)(xing)鍍(du)(du)(du)銅(tong)(tong)和酸(suan)(suan)(suan)(suan)性(xing)(xing)(xing)(xing)鍍(du)(du)(du)銅(tong)(tong)二法(fa)。通(tong)常為(wei)(wei)(wei)了(le)獲(huo)得(de)較薄的細致(zhi)光滑的銅(tong)(tong)鍍(du)(du)(du)層，將表面除(chu)去油銹(xiu)的鋼鐵等(deng)(deng)制件作陰極，純銅(tong)(tong)板作陽極，掛(gua)于(yu)含有(you)氰(qing)化亞銅(tong)(tong)、氰(qing)化鈉和碳酸(suan)(suan)(suan)(suan)鈉等(deng)(deng)成分的堿性(xing)(xing)(xing)(xing)電鍍(du)(du)(du)液中，進行(xing)堿性(xing)(xing)(xing)(xing)（氰(qing)化物）鍍(du)(du)(du)銅(tong)(tong)。為(wei)(wei)(wei)了(le)獲(huo)得(de)較厚的銅(tong)(tong)鍍(du)(du)(du)層，必須先將鍍(du)(du)(du)件進行(xing)堿性(xing)(xing)(xing)(xing)鍍(du)(du)(du)銅(tong)(tong)，再置于(yu)含有(you)硫(liu)酸(suan)(suan)(suan)(suan)銅(tong)(tong)、硫(liu)酸(suan)(suan)(suan)(suan)鎳(nie)和硫(liu)酸(suan)(suan)(suan)(suan)等(deng)(deng)成分的電解液中，進行(xing)酸(suan)(suan)(suan)(suan)性(xing)(xing)(xing)(xing)鍍(du)(du)(du)銅(tong)(tong)。此外(wai)，還有(you)焦磷(lin)酸(suan)(suan)(suan)(suan)鹽、酒(jiu)石酸(suan)(suan)(suan)(suan)鹽、乙二胺等(deng)(deng)配制的無氰(qing)電解液。焦磷(lin)酸(suan)(suan)(suan)(suan)鹽電解液已被(bei)廣泛采用(yong)(yong)。
