碳纖(xian)(xian)維(wei)(wei)導輥(gun)(gun)與金(jin)屬(shu)(shu)材料比(bi)較大(da)的差別就是(shi)碳纖(xian)(xian)維(wei)(wei)是(shi)一種非(fei)金(jin)屬(shu)(shu)材料，其(qi)電化(hua)學活性較低，不論是(shi)在惡劣的露天環境還(huan)是(shi)化(hua)學介質腐(fu)蝕、潮濕的環境中都能夠正(zheng)常工(gong)作，使(shi)用壽命較長，碳纖(xian)(xian)維(wei)(wei)導輥(gun)(gun)比(bi)金(jin)屬(shu)(shu)導輥(gun)(gun)更加耐磨，維(wei)(wei)修方便。碳纖(xian)(xian)維(wei)(wei)導輥(gun)(gun)的工(gong)作溫度高，防火阻燃，保(bao)證了使(shi)用過程(cheng)中的安(an)全性，其(qi)熱膨脹(zhang)系數小，基本上不會隨工(gong)作溫度的變(bian)化(hua)發生變(bian)形(xing)，尺寸(cun)穩定。
