根據鍍(du)(du)(du)(du)件(jian)(jian)表(biao)面積和(he)鍍(du)(du)(du)(du)件(jian)(jian)的(de)重(zhong)童選(xuan)(xuan)擇銅(tong)(tong)絲(si)的(de)直(zhi)徑(jing),應(ying)在(zai)能(neng)使電(dian)流正常暢通,并(bing)能(neng)承受(shou)懸掛重(zhong)談(tan)的(de)前提下,盡(jin)最小一點(dian).銅(tong)(tong)絲(si)過(guo)粗,除(chu)對鍍(du)(du)(du)(du)件(jian)(jian)會造成過(guo)大面積的(de)遮蓋之外(wai),還可(ke)能(neng)導致鍍(du)(du)(du)(du)件(jian)(jian)變形;銅(tong)(tong)絲(si)過(guo)細,除(chu)承受(shou)不(bu)(bu)了鍍(du)(du)(du)(du)件(jian)(jian)重(zhong)量(liang)外(wai),還可(ke)能(neng)影(ying)響到所需(xu)電(dian)流的(de)通過(guo)而(er)(er)不(bu)(bu)能(neng)獲(huo)得(de)正常的(de)鍍(du)(du)(du)(du)層質量(liang)。另(ling)外(wai),受(shou)鍍(du)(du)(du)(du)的(de)鍍(du)(du)(du)(du)種也是應(ying)考慮的(de)因(yin)(yin)素。例如,在(zai)綁(bang)扎鍍(du)(du)(du)(du)亮鎳件(jian)(jian)時,銅(tong)(tong)絲(si)不(bu)(bu)宜選(xuan)(xuan)得(de)過(guo)細。因(yin)(yin)為亮鎳很脆(cui),若鋼絲(si)過(guo)分細小。就有可(ke)能(neng)在(zai)電(dian)鍍(du)(du)(du)(du)時因(yin)(yin)陰極棒的(de)移動或鍍(du)(du)(du)(du)件(jian)(jian)出枯時受(shou)力而(er)(er)被(bei)折斷(duan)。當綁(bang)扎已經(jing)鍍(du)(du)(du)(du)鎳并(bing)經(jing)拋光(guang)過(guo)的(de)裝(zhuang)飾性鍍(du)(du)(du)(du)鉻(ge)件(jian)(jian)時,所用(yong)的(de)銅(tong)(tong)絲(si)則宜適當選(xuan)(xuan)得(de)細點(dian),以減輕(qing)銅(tong)(tong)絲(si)在(zai)鍍(du)(du)(du)(du)件(jian)(jian)上的(de)遮蓋面,且(qie)該銅(tong)(tong)絲(si)應(ying)先經(jing)鍍(du)(du)(du)(du)一層鉻(ge)才可(ke)使用(yong),否則綁(bang)扎處難(nan)免(mian)產(chan)生銅(tong)(tong)絲(si)影(ying)。一般情況下,不(bu)(bu)宜用(yong)雙股鋼絲(si)綁(bang)扎鍍(du)(du)(du)(du)件(jian)(jian),否則極容易產(chan)生銅(tong)(tong)絲(si)影(ying)。
