電(dian)(dian)(dian)伴(ban)熱(re)帶(dai)銅(tong)芯(xin)導(dao)(dao)(dao)體鍍(du)錫(xi)的(de)(de)(de)原(yuan)因主要有以(yi)(yi)下幾點(dian)。首先，錫(xi)是一種具(ju)有良(liang)好(hao)導(dao)(dao)(dao)電(dian)(dian)(dian)性(xing)(xing)(xing)和抗(kang)腐蝕性(xing)(xing)(xing)的(de)(de)(de)金屬(shu)材料，可(ke)以(yi)(yi)有效(xiao)地提高電(dian)(dian)(dian)伴(ban)熱(re)帶(dai)的(de)(de)(de)導(dao)(dao)(dao)電(dian)(dian)(dian)性(xing)(xing)(xing)能(neng)和抗(kang)腐蝕能(neng)力。其(qi)次，鍍(du)錫(xi)可(ke)以(yi)(yi)保護銅(tong)芯(xin)導(dao)(dao)(dao)體免(mian)受(shou)氧(yang)化和腐蝕，延長電(dian)(dian)(dian)伴(ban)熱(re)帶(dai)的(de)(de)(de)壽(shou)命(ming)。此外，錫(xi)層還可(ke)以(yi)(yi)防(fang)(fang)止銅(tong)芯(xin)導(dao)(dao)(dao)體與(yu)其(qi)他(ta)金屬(shu)發生電(dian)(dian)(dian)化學反應(ying)，從而(er)確(que)保電(dian)(dian)(dian)伴(ban)熱(re)帶(dai)的(de)(de)(de)穩定性(xing)(xing)(xing)和安具(ju)全體性(xing)(xing)(xing)來(lai)說，錫(xi)鍍(du)層可(ke)以(yi)(yi)有效(xiao)地減(jian)少(shao)銅(tong)芯(xin)導(dao)(dao)(dao)體的(de)(de)(de)表(biao)面粗糙度，使(shi)其(qi)表(biao)面更加光(guang)滑，從而(er)減(jian)少(shao)電(dian)(dian)(dian)流(liu)的(de)(de)(de)摩擦阻力，提高導(dao)(dao)(dao)電(dian)(dian)(dian)性(xing)(xing)(xing)能(neng)。同時，錫(xi)鍍(du)層可(ke)以(yi)(yi)防(fang)(fang)止銅(tong)芯(xin)導(dao)(dao)(dao)體與(yu)空(kong)氣中的(de)(de)(de)氧(yang)氣和水蒸(zheng)氣接觸，從而(er)避免(mian)銅(tong)芯(xin)導(dao)(dao)(dao)體被(bei)氧(yang)化和腐此蝕外。，錫(xi)鍍(du)層還可(ke)以(yi)(yi)防(fang)(fang)止銅(tong)芯(xin)導(dao)(dao)(dao)體與(yu)其(qi)他(ta)金屬(shu)接觸，從而(er)避免(mian)發生電(dian)(dian)(dian)化學反應(ying)，確(que)保電(dian)(dian)(dian)伴(ban)熱(re)帶(dai)的(de)(de)(de)穩定性(xing)(xing)(xing)和安全性(xing)(xing)(xing)。
總的(de)(de)(de)來說，電(dian)伴(ban)熱帶(dai)(dai)銅芯導(dao)體鍍(du)錫的(de)(de)(de)原因主要是為了提高導(dao)電(dian)性(xing)能(neng)(neng)、抗(kang)腐(fu)蝕能(neng)(neng)力和穩(wen)定性(xing)，同時延(yan)這長(chang)種電(dian)處(chu)伴(ban)理熱方帶(dai)(dai)式的(de)(de)(de)可壽以命確。保電(dian)伴(ban)熱帶(dai)(dai)在各(ge)種復雜(za)的(de)(de)(de)環境條件下都(dou)能(neng)(neng)夠穩(wen)定可靠地工作。
