我們確實缺銅(tong)(tong)(tong)(tong)其中通(tong)過自己礦山生產和(he)廢(fei)銅(tong)(tong)(tong)(tong)回(hui)收的(de)(de)銅(tong)(tong)(tong)(tong)產量(liang)僅100萬噸，占22%，其余350萬噸是(shi)通(tong)過進口銅(tong)(tong)(tong)(tong)精礦、粗銅(tong)(tong)(tong)(tong)、廢(fei)雜(za)銅(tong)(tong)(tong)(tong)、電(dian)解銅(tong)(tong)(tong)(tong)和(he)銅(tong)(tong)(tong)(tong)材(cai)滿足國(guo)內需求的(de)(de)。如(ru)果(guo)我們在國(guo)際市場銅(tong)(tong)(tong)(tong)價非理性暴漲(zhang)的(de)(de)情況下，一窩蜂(feng)到國(guo)外開(kai)發銅(tong)(tong)(tong)(tong)礦，廢(fei)銅(tong)(tong)(tong)(tong)回(hui)收勢必抬高基礎價格，付出沉(chen)重的(de)(de)代價。對于變形的(de)(de)窗扇(shan)，如(ru)果(guo)說不算嚴(yan)重的(de)(de)話(hua)，廢(fei)鋁(lv)回(hui)收價錢，可(ke)能通(tong)過加裝(zhuang)中間鎖來加以矯正；如(ru)果(guo)變形嚴(yan)重到一定程度了，可(ke)能就(jiu)要換窗扇(shan)了。順便提一下。

成(cheng)(cheng)(cheng)色(se)較好的(de)(de)(de)(de)鋁(lv)(lv)制(zhi)(zhi)品(pin)回(hui)收(shou)后(hou)(hou)可(ke)(ke)以(yi)使(shi)用：就我們對(dui)廢(fei)鋁(lv)(lv)的(de)(de)(de)(de)了解來(lai)看(kan)，成(cheng)(cheng)(cheng)色(se)較好的(de)(de)(de)(de)鋁(lv)(lv)制(zhi)(zhi)品(pin)一般在回(hui)收(shou)之后(hou)(hou)重(zhong)新(xin)包(bao)裝(zhuang)之后(hou)(hou)也(ye)可(ke)(ke)以(yi)再次銷售和使(shi)用。所以(yi)針對(dui)這類(lei)型的(de)(de)(de)(de)廢(fei)鋁(lv)(lv)回(hui)收(shou)，要給出合(he)理(li)(li)的(de)(de)(de)(de)價格，專門回(hui)收(shou)公司也(ye)會(hui)根據鋁(lv)(lv)制(zhi)(zhi)品(pin)本身的(de)(de)(de)(de)外形(xing)和使(shi)用性(xing)(xing)能(neng)給出報價，通過(guo)這些方(fang)面不僅可(ke)(ke)以(yi)詳細(xi)了解鋁(lv)(lv)制(zhi)(zhi)品(pin)的(de)(de)(de)(de)作用價值，也(ye)可(ke)(ke)以(yi)知道回(hui)收(shou)廠家的(de)(de)(de)(de)發展情況。所有(you)的(de)(de)(de)(de)廢(fei)銅(tong)(tong)都(dou)可(ke)(ke)以(yi)再生(sheng)。再生(sheng)工藝很簡單。首(shou)先(xian)把收(shou)集的(de)(de)(de)(de)廢(fei)銅(tong)(tong)進行(xing)分(fen)揀(jian)，沒(mei)有(you)受(shou)污(wu)(wu)染(ran)的(de)(de)(de)(de)廢(fei)銅(tong)(tong)或成(cheng)(cheng)(cheng)分(fen)相(xiang)同的(de)(de)(de)(de)銅(tong)(tong)合(he)金可(ke)(ke)以(yi)回(hui)爐(lu)熔化(hua)后(hou)(hou)直接利(li)用，被(bei)(bei)嚴重(zhong)污(wu)(wu)染(ran)的(de)(de)(de)(de)廢(fei)銅(tong)(tong)要進一步精(jing)煉處(chu)理(li)(li)去除(chu)雜(za)質(zhi)；對(dui)于相(xiang)互混雜(za)的(de)(de)(de)(de)銅(tong)(tong)合(he)金廢(fei)料(liao)，則需熔化(hua)后(hou)(hou)進行(xing)成(cheng)(cheng)(cheng)分(fen)調(diao)整。通過(guo)這樣的(de)(de)(de)(de)再生(sheng)處(chu)理(li)(li)，銅(tong)(tong)的(de)(de)(de)(de)物理(li)(li)、化(hua)學性(xing)(xing)質(zhi)不受(shou)損害，使(shi)它得(de)到完全的(de)(de)(de)(de)更新(xin)。銅(tong)(tong)具有(you)優良的(de)(de)(de)(de)導熱和導電性(xing)(xing)能(neng)，以(yi)及(ji)良好的(de)(de)(de)(de)抗(kang)腐蝕和機械性(xing)(xing)能(neng)。銅(tong)(tong)容(rong)易被(bei)(bei)加工成(cheng)(cheng)(cheng)復雜(za)的(de)(de)(de)(de)形(xing)狀和細(xi)絲。建(jian)筑(zhu)師經常利(li)用其(qi)(qi)亮紅(hong)色(se)和其(qi)(qi)被(bei)(bei)侵蝕后(hou)(hou)的(de)(de)(de)(de)銅(tong)(tong)綠，來(lai)作為建(jian)筑(zhu)物、頂棚和戶外裝(zhuang)置的(de)(de)(de)(de)裝(zhuang)飾(shi)。

首先對(dui)廢銅(tong)(tong)進(jin)行(xing)再生整理(li)，經(jing)熔化(hua)后(hou)經(jing)無污染(ran)的(de)(de)銅(tong)(tong)或銅(tong)(tong)合金同(tong)成(cheng)分(fen)直接處理(li)，嚴(yan)重污染(ran)銅(tong)(tong)精(jing)煉處理(li)，進(jin)一步(bu)清(qing)除(chu)雜質；對(dui)銅(tong)(tong)合金廢料進(jin)行(xing)混合、熔化(hua)成(cheng)分(fen)調(diao)整。電(dian)力輸送需要(yao)大量(liang)導(dao)電(dian)性高的(de)(de)銅(tong)(tong)，主要(yao)用(yong)(yong)于電(dian)力線(xian)、電(dian)纜(lan)、母線(xian)、變壓器、開關、接插(cha)件(jian)和(he)(he)聯軸器。80年代以(yi)來，由于光(guang)纜(lan)容量(liang)大，銅(tong)(tong)纜(lan)在通信干線(xian)上不斷更換，得到了迅速(su)的(de)(de)推(tui)廣和(he)(he)應用(yong)(yong)。銅(tong)(tong)是人類與(yu)有色(se)金屬之間的(de)(de)關系(xi)非常(chang)密切，不僅具有良好的(de)(de)導(dao)電(dian)性、導(dao)熱性、耐腐蝕性和(he)(he)自然資(zi)源(yuan)豐富等(deng)優(you)良性能仍然需要(yao)使用(yong)(yong)大量(liang)的(de)(de)銅(tong)(tong)來將電(dian)能轉換成(cheng)光(guang)能并進(jin)入用(yong)(yong)戶(hu)的(de)(de)線(xian)路。
