用途(tu)

紫銅(tong)(tong)(tong)(tong)的用途比純(chun)(chun)(chun)鐵廣泛(fan)得(de)多,每(mei)年有50%的銅(tong)(tong)(tong)(tong)被電(dian)(dian)解(jie)(jie)提純(chun)(chun)(chun)為,用于(yu)電(dian)(dian)氣工業。這里所說的紫銅(tong)(tong)(tong)(tong),確實要非常純(chun)(chun)(chun),含銅(tong)(tong)(tong)(tong)達99.95%以(yi)(yi)上(shang)才行,極(ji)少(shao)量的雜(za)質(zhi),特別是磷、砷、鋁等(deng),會(hui)(hui)大(da)大(da)降低銅(tong)(tong)(tong)(tong)的導電(dian)(dian)率。主(zhu)要用于(yu)制(zhi)作發電(dian)(dian)機﹑母(mu)線﹑電(dian)(dian)纜(lan)﹑開(kai)關裝(zhuang)(zhuang)置(zhi)﹑變(bian)壓器等(deng)電(dian)(dian)工器材(cai)和(he)熱(re)交換(huan)器﹑管(guan)道﹑太陽能(neng)加熱(re)裝(zhuang)(zhuang)置(zhi)的等(deng)導熱(re)器材(cai)。銅(tong)(tong)(tong)(tong)中含氧(煉銅(tong)(tong)(tong)(tong)時容(rong)易混(hun)入(ru)少(shao)量氧)對導電(dian)(dian)率影(ying)響很大(da),用于(yu)電(dian)(dian)氣工業的銅(tong)(tong)(tong)(tong)一般都必須是無氧銅(tong)(tong)(tong)(tong)。另外,鉛、銻、鉍等(deng)雜(za)質(zhi)會(hui)(hui)使銅(tong)(tong)(tong)(tong)的結晶不(bu)能(neng)結合(he)在一起(qi),造成熱(re)脆,也(ye)會(hui)(hui)影(ying)響純(chun)(chun)(chun)銅(tong)(tong)(tong)(tong)的加工。這種很高(gao)的純(chun)(chun)(chun)銅(tong)(tong)(tong)(tong),一般用精制(zhi):把不(bu)純(chun)(chun)(chun)銅(tong)(tong)(tong)(tong)(即粗銅(tong)(tong)(tong)(tong))作陽極(ji),純(chun)(chun)(chun)銅(tong)(tong)(tong)(tong)作陰(yin)(yin)極(ji),以(yi)(yi)硫酸銅(tong)(tong)(tong)(tong)溶(rong)液為電(dian)(dian)解(jie)(jie)液。當電(dian)(dian)流通過后,陽極(ji)上(shang)不(bu)純(chun)(chun)(chun)的銅(tong)(tong)(tong)(tong)逐漸(jian)熔解(jie)(jie),純(chun)(chun)(chun)銅(tong)(tong)(tong)(tong)便逐漸(jian)沉淀在陰(yin)(yin)極(ji)上(shang)。這樣(yang)精制(zhi)而得(de)的銅(tong)(tong)(tong)(tong);純(chun)(chun)(chun)度可達99.99%。

紫銅還(huan)用于電(dian)機短路環,電(dian)磁加(jia)熱感應器(qi)的制作,和大功(gong)率電(dian)子(zi)元件上面,接線排(pai)接線端子(zi)之類(lei)的。

紫銅也運用到(dao)了門、窗、扶手等家具及裝(zhuang)飾(shi)上。
