電鍍銅鋼板

電鍍銅鋼板用(yong)于(yu)鑄模，鍍(du)(du)(du)鎳(nie)，鍍(du)(du)(du)鉻，鍍(du)(du)(du)銀和(he)鍍(du)(du)(du)金的打底，修(xiu)復(fu)磨(mo)損部(bu)分(fen)，防止局(ju)部(bu)滲碳和(he)提(ti)高導電性。分(fen)為(wei)(wei)堿(jian)性鍍(du)(du)(du)銅(tong)(tong)和(he)酸(suan)性鍍(du)(du)(du)銅(tong)(tong)二法。通常為(wei)(wei)了獲得較薄的細致光滑的銅(tong)(tong)鍍(du)(du)(du)層，將(jiang)表(biao)面除(chu)去油銹(xiu)的鋼鐵(tie)等(deng)制(zhi)件作陰極(ji)，純銅(tong)(tong)板作陽(yang)極(ji)，掛于(yu)含有氰化亞銅(tong)(tong)、氰化鈉和(he)碳酸(suan)鈉等(deng)成(cheng)分(fen)的堿(jian)性電鍍(du)(du)(du)液(ye)中(zhong)，進(jin)(jin)行(xing)堿(jian)性（氰化物(wu)）鍍(du)(du)(du)銅(tong)(tong)。為(wei)(wei)了獲得較厚的銅(tong)(tong)鍍(du)(du)(du)層，必須先將(jiang)鍍(du)(du)(du)件進(jin)(jin)行(xing)堿(jian)性鍍(du)(du)(du)銅(tong)(tong)，再置于(yu)含有硫(liu)酸(suan)銅(tong)(tong)、硫(liu)酸(suan)鎳(nie)和(he)硫(liu)酸(suan)等(deng)成(cheng)分(fen)的電解(jie)液(ye)中(zhong)，進(jin)(jin)行(xing)酸(suan)性鍍(du)(du)(du)銅(tong)(tong)。此外，還有焦(jiao)(jiao)磷(lin)酸(suan)鹽(yan)、酒石酸(suan)鹽(yan)、乙二胺等(deng)配制(zhi)的無氰電解(jie)液(ye)。焦(jiao)(jiao)磷(lin)酸(suan)鹽(yan)電解(jie)液(ye)已被廣泛采用(yong)。
