電鍍銅鋼板加工

電鍍銅鋼板用于鑄模，鍍(du)(du)(du)(du)鎳(nie)(nie)，鍍(du)(du)(du)(du)鉻，鍍(du)(du)(du)(du)銀和(he)(he)鍍(du)(du)(du)(du)金的(de)打底，修復磨損部分(fen)，防止局部滲碳(tan)和(he)(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)(he)酸性(xing)(xing)(xing)鍍(du)(du)(du)(du)銅(tong)(tong)(tong)二法。通常為(wei)了(le)獲(huo)得較薄的(de)細(xi)致光滑(hua)的(de)銅(tong)(tong)(tong)鍍(du)(du)(du)(du)層(ceng)，將表面除去(qu)油銹的(de)鋼鐵等制(zhi)件作陰極，純銅(tong)(tong)(tong)板作陽極，掛于含有氰化亞銅(tong)(tong)(tong)、氰化鈉(na)和(he)(he)碳(tan)酸鈉(na)等成(cheng)分(fen)的(de)堿(jian)性(xing)(xing)(xing)電(dian)鍍(du)(du)(du)(du)液(ye)中，進(jin)(jin)行(xing)堿(jian)性(xing)(xing)(xing)（氰化物）鍍(du)(du)(du)(du)銅(tong)(tong)(tong)。為(wei)了(le)獲(huo)得較厚的(de)銅(tong)(tong)(tong)鍍(du)(du)(du)(du)層(ceng)，必須先將鍍(du)(du)(du)(du)件進(jin)(jin)行(xing)堿(jian)性(xing)(xing)(xing)鍍(du)(du)(du)(du)銅(tong)(tong)(tong)，再置(zhi)于含有硫酸銅(tong)(tong)(tong)、硫酸鎳(nie)(nie)和(he)(he)硫酸等成(cheng)分(fen)的(de)電(dian)解(jie)液(ye)中，進(jin)(jin)行(xing)酸性(xing)(xing)(xing)鍍(du)(du)(du)(du)銅(tong)(tong)(tong)。此外，還有焦磷酸鹽、酒石酸鹽、乙二胺等配制(zhi)的(de)無氰電(dian)解(jie)液(ye)。焦磷酸鹽電(dian)解(jie)液(ye)已被廣泛采用。
