用途(tu)

紫銅(tong)(tong)(tong)(tong)的用(yong)途(tu)比純(chun)(chun)(chun)(chun)(chun)鐵廣(guang)泛(fan)得多,每年有(you)50%的銅(tong)(tong)(tong)(tong)被電(dian)解(jie)(jie)提(ti)純(chun)(chun)(chun)(chun)(chun)為(wei),用(yong)于電(dian)氣工(gong)業。這里所說的紫銅(tong)(tong)(tong)(tong),確實(shi)要(yao)非常純(chun)(chun)(chun)(chun)(chun),含銅(tong)(tong)(tong)(tong)達(da)99.95%以上才行,極(ji)(ji)少量(liang)(liang)的雜(za)(za)質(zhi),特(te)別(bie)是(shi)磷、砷、鋁等,會(hui)大(da)大(da)降低銅(tong)(tong)(tong)(tong)的導(dao)電(dian)率。主要(yao)用(yong)于制(zhi)作發(fa)電(dian)機﹑母線(xian)﹑電(dian)纜(lan)﹑開關裝(zhuang)置(zhi)﹑變壓器(qi)等電(dian)工(gong)器(qi)材和(he)熱交換器(qi)﹑管道﹑太陽(yang)能(neng)加(jia)熱裝(zhuang)置(zhi)的等導(dao)熱器(qi)材。銅(tong)(tong)(tong)(tong)中含氧(yang)(煉銅(tong)(tong)(tong)(tong)時(shi)容(rong)易混(hun)入少量(liang)(liang)氧(yang))對導(dao)電(dian)率影響很大(da),用(yong)于電(dian)氣工(gong)業的銅(tong)(tong)(tong)(tong)一般(ban)都必須是(shi)無氧(yang)銅(tong)(tong)(tong)(tong)。另外,鉛、銻、鉍等雜(za)(za)質(zhi)會(hui)使(shi)銅(tong)(tong)(tong)(tong)的結(jie)晶不(bu)能(neng)結(jie)合在(zai)一起,造成熱脆,也會(hui)影響純(chun)(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)(tong)的加(jia)工(gong)。這種很高的純(chun)(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)(tong),一般(ban)用(yong)精制(zhi):把不(bu)純(chun)(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)(tong)(即粗銅(tong)(tong)(tong)(tong))作陽(yang)極(ji)(ji),純(chun)(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)(tong)作陰極(ji)(ji),以硫酸銅(tong)(tong)(tong)(tong)溶(rong)液(ye)為(wei)電(dian)解(jie)(jie)液(ye)。當電(dian)流通過后,陽(yang)極(ji)(ji)上不(bu)純(chun)(chun)(chun)(chun)(chun)的銅(tong)(tong)(tong)(tong)逐漸(jian)熔解(jie)(jie),純(chun)(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)(tong)便逐漸(jian)沉淀在(zai)陰極(ji)(ji)上。這樣精制(zhi)而得的銅(tong)(tong)(tong)(tong);純(chun)(chun)(chun)(chun)(chun)度可達(da)99.99%。

紫銅還(huan)用(yong)于電機短路環,電磁加熱感應器的制(zhi)作,和大功率(lv)電子(zi)元(yuan)件上面,接線排接線端子(zi)之類的。

紫銅(tong)也運用到了門(men)、窗、扶手等家具及(ji)裝飾上。
