哈爾濱鍋爐回收(shou)認為(wei)環保(bao)行業正(zheng)在國家的(de)(de)政策下慢慢的(de)(de)成長(chang)著，我們(men)同時也希望(wang)有(you)更多(duo)的(de)(de)企業關注他們(men)。讓我們(men)擁有(you)一個美(mei)好而又綠(lv)色的(de)(de)地球。廢(fei)銅(tong)回收(shou)的(de)(de)應用很多(duo)，主要給大家講(jiang)下銅(tong)在建筑中的(de)(de)應用吧！

　　兩大廢銅來源

　　一類是新廢(fei)銅(tong)(tong)，它是銅(tong)(tong)工(gong)業(ye)生產(chan)過(guo)程中產(chan)生的廢(fei)料。冶(ye)金廠(chang)(chang)的叫(jiao)"本廠(chang)(chang)廢(fei)銅(tong)(tong)"或(huo)"周轉(zhuan)廢(fei)銅(tong)(tong)"。銅(tong)(tong)加工(gong)廠(chang)(chang)產(chan)生的廢(fei)銅(tong)(tong)屑及直(zhi)接返回供(gong)應廠(chang)(chang)的叫(jiao)做"工(gong)業(ye)廢(fei)雜銅(tong)(tong)"、"現貨廢(fei)雜銅(tong)(tong)"或(huo)新廢(fei)雜銅(tong)(tong)。

　　另一(yi)(yi)(yi)類(lei)是舊(jiu)廢(fei)(fei)(fei)(fei)銅(tong)，它是使(shi)用后被(bei)廢(fei)(fei)(fei)(fei)棄的物品(pin)，如從舊(jiu)建筑物及運(yun)輸(shu)系統拋(pao)棄或拆卸(xie)的叫舊(jiu)廢(fei)(fei)(fei)(fei)雜銅(tong)。銅(tong)和銅(tong)基材料，不論(lun)處于(yu)裸露狀態，還是被(bei)包(bao)在最(zui)終產品(pin)里，在產品(pin)壽命周期的各(ge)個階段都可回收再(zai)生(sheng)。一(yi)(yi)(yi)般來說，用于(yu)再(zai)生(sheng)的廢(fei)(fei)(fei)(fei)銅(tong)中新廢(fei)(fei)(fei)(fei)銅(tong)占一(yi)(yi)(yi)半以(yi)上。

　　而全部廢(fei)(fei)(fei)雜(za)(za)銅(tong)(tong)經(jing)再(zai)(zai)加(jia)工(gong)后有大約1/3以精銅(tong)(tong)的(de)(de)形式(shi)返回市場，另2/3以非(fei)精煉銅(tong)(tong)或銅(tong)(tong)合(he)金的(de)(de)形式(shi)重新使(shi)用。直(zhi)接(jie)(jie)(jie)應(ying)用廢(fei)(fei)(fei)雜(za)(za)銅(tong)(tong)的(de)(de)前提是(shi)嚴格的(de)(de)分類堆(dui)放(fang)及嚴格的(de)(de)分揀。直(zhi)接(jie)(jie)(jie)應(ying)用廢(fei)(fei)(fei)雜(za)(za)銅(tong)(tong)具有簡化工(gong)藝、設備簡單(dan)、回收(shou)率高、能(neng)耗少、成本(ben)低(di)、污染輕等(deng)優點(dian)。直(zhi)接(jie)(jie)(jie)應(ying)用廢(fei)(fei)(fei)雜(za)(za)銅(tong)(tong)的(de)(de)多少，大體上(shang)反映了一個國家銅(tong)(tong)的(de)(de)再(zai)(zai)生水平。相(xiang)比之下，我國廢(fei)(fei)(fei)雜(za)(za)銅(tong)(tong)的(de)(de)直(zhi)接(jie)(jie)(jie)使(shi)用率較低(di)，每年約為20萬t，僅占廢(fei)(fei)(fei)雜(za)(za)銅(tong)(tong)總(zong)回收(shou)量(liang)的(de)(de)30%~40%，并(bing)(bing)且(qie)黃銅(tong)(tong)加(jia)工(gong)材的(de)(de)生產(chan)多由鄉鎮企業運(yun)作(zuo)，大大降低(di)了經(jing)濟(ji)效益，并(bing)(bing)在(zai)能(neng)耗、環保方面帶來后患。

　　我國進口廢(fei)雜銅主要(yao)來(lai)自美(mei)(mei)、日、德、俄，其中美(mei)(mei)國高居(ju)榜首(shou)，而美(mei)(mei)國對(dui)廢(fei)雜銅的(de)(de)管(guan)理又有嚴格的(de)(de)規定。以美(mei)(mei)國的(de)(de)分類標準(zhun)作(zuo)為典型加以介(jie)紹。

　　美國通常把含Cu量(liang)大(da)于99%的(de)銅(tong)(tong)(tong)(tong)材叫做1號(hao)銅(tong)(tong)(tong)(tong)，1號(hao)銅(tong)(tong)(tong)(tong)可以(yi)直接(jie)重(zhong)熔(rong)和使用(yong)(yong)，不要求進一步加(jia)工(gong)(gong)；把銅(tong)(tong)(tong)(tong)含量(liang)至低為94.5%的(de)銅(tong)(tong)(tong)(tong)叫2號(hao)銅(tong)(tong)(tong)(tong)，這種廢雜(za)(za)銅(tong)(tong)(tong)(tong)在以(yi)金屬(shu)銅(tong)(tong)(tong)(tong)的(de)形態使用(yong)(yong)之前，通常一定(ding)要重(zhong)熔(rong)。其(qi)它常見的(de)分(fen)類等級(ji)還包括(kuo)加(jia)鉛黃(huang)銅(tong)(tong)(tong)(tong)、黃(huang)銅(tong)(tong)(tong)(tong)與低鋅黃(huang)銅(tong)(tong)(tong)(tong)、彈(dan)殼黃(huang)銅(tong)(tong)(tong)(tong)、汽車散熱片、高銅(tong)(tong)(tong)(tong)黃(huang)銅(tong)(tong)(tong)(tong)（紅色黃(huang)銅(tong)(tong)(tong)(tong)），以(yi)及(ji)應用(yong)(yong)十分(fen)廣(guang)泛的(de)高速切削黃(huang)銅(tong)(tong)(tong)(tong)，其(qi)車屑直接(jie)再(zai)生(sheng)，以(yi)同成(cheng)(cheng)分(fen)合金的(de)形式用(yong)(yong)于重(zhong)新加(jia)工(gong)(gong)黃(huang)銅(tong)(tong)(tong)(tong)產品。對制造廠家(jia)而言(yan)，其(qi)主(zhu)要優點就是大(da)幅(fu)度降(jiang)低凈金屬(shu)消耗的(de)成(cheng)(cheng)本。廢雜(za)(za)銅(tong)(tong)(tong)(tong)也用(yong)(yong)于生(sheng)產銅(tong)(tong)(tong)(tong)的(de)化學(xue)制品，但(dan)不易獲得定(ding)量(liang)數據(ju)。

　　其實它們都叫紫銅(tong)(tong)，不過(guo)市(shi)場(chang)交易比較多(duo)的(de)那種(zhong)叫做(zuo)紫雜(za)銅(tong)(tong)，銅(tong)(tong)含(han)量在80%左右(you)，還有黃銅(tong)(tong)也交易的(de)比較多(duo)的(de)廢(fei)金屬品種(zhong)，一(yi)般的(de)黃銅(tong)(tong)是59黃銅(tong)(tong)就是含(han)純(chun)銅(tong)(tong)59%的(de)，其余的(de)成分以鋅為(wei)主，這種(zhong)銅(tong)(tong)也叫做(zuo)黃雜(za)銅(tong)(tong)
