      回收鍍錫銅不得不知道的知識!

  

  鍍(du)錫銅,是指(zhi)表(biao)面鍍(du)有(you)一(yi)薄(bo)層(ceng)金屬錫的銅,如(ru)鍍(du)錫銅線,在線纜加工制造過程中有(you)一(yi)定的應用。

  

  鍍(du)(du)錫能防止銅(tong)(tong)暴露在空氣中而被氧(yang)化(hua)形成一(yi)層膜——銅(tong)(tong)綠(lv)。而銅(tong)(tong)綠(lv)的(de)導電性很差會增加(jia)電阻。盛裝食(shi)物的(de)器皿產生銅(tong)(tong)綠(lv)后可能對(dui)人體有害。因而鍍(du)(du)錫主要就是為了防止銅(tong)(tong)被氧(yang)化(hua)。

  

  銅(tong)(tong)由于其優異的(de)性(xing)(xing)(xing)(xing)能(neng)(neng)以及低(di)廉的(de)價格,被廣泛應用于電(dian)子信息(xi)、潤(run)滑、催化(hua)(hua)(hua)和冶(ye)金(jin)等(deng)領域(yu)。但(dan)銅(tong)(tong)在(zai)(zai)空(kong)氣(qi)中極易氧(yang)化(hua)(hua)(hua),并且粒(li)度越(yue)細,氧(yang)化(hua)(hua)(hua)越(yue)嚴重。為了提高(gao)銅(tong)(tong)的(de)抗(kang)氧(yang)化(hua)(hua)(hua)性(xing)(xing)(xing)(xing)能(neng)(neng),可(ke)在(zai)(zai)銅(tong)(tong)表(biao)面包覆(fu)惰性(xing)(xing)(xing)(xing)金(jin)屬。包覆(fu)惰性(xing)(xing)(xing)(xing)金(jin)屬層不僅(jin)能(neng)(neng)較顯著地(di)提高(gao)銅(tong)(tong)的(de)抗(kang)氧(yang)化(hua)(hua)(hua)性(xing)(xing)(xing)(xing)能(neng)(neng),而且能(neng)(neng)較好(hao)地(di)保持其導電(dian)性(xing)(xing)(xing)(xing)。錫(xi)雖然不屬于惰性(xing)(xing)(xing)(xing)金(jin)屬,性(xing)(xing)(xing)(xing)質也比銅(tong)(tong)活潑,但(dan)常(chang)溫下錫(xi)在(zai)(zai)空(kong)氣(qi)中很穩定(ding),因(yin)錫(xi)的(de)表(biao)面會生(sheng)成(cheng)一(yi)層致密的(de)氧(yang)化(hua)(hua)(hua)物膜,阻(zu)止錫(xi)的(de)繼(ji)續(xu)氧(yang)化(hua)(hua)(hua)。因(yin)此,銅(tong)(tong)表(biao)面鍍(du)錫(xi)可(ke)在(zai)(zai)一(yi)定(ding)程度上提高(gao)銅(tong)(tong)的(de)抗(kang)氧(yang)化(hua)(hua)(hua)性(xing)(xing)(xing)(xing)。鍍(du)錫(xi)銅(tong)(tong)的(de)穩定(ding)性(xing)(xing)(xing)(xing)、導電(dian)性(xing)(xing)(xing)(xing)、耐磨性(xing)(xing)(xing)(xing)、抗(kang)腐蝕性(xing)(xing)(xing)(xing)和電(dian)磁屏蔽性(xing)(xing)(xing)(xing)都(dou)較好(hao),具有很好(hao)的(de)應用前景。
