說到白鐵大家可能都非常正規白鐵加工模糊,是不是白色的鐵就叫白鐵?其實白鐵就是大家都非常熟悉的鍍鋅鐵。鐵是我們白鐵加工生活(huo)(huo)中使用廣泛的(de)金(jin)屬材(cai)料,在任何地方都會有鐵(tie)的(de)使用。人(ren)們之所以要對(dui)鐵(tie)進行鍍鋅,是(shi)(shi)因為鐵(tie)在代大(da)氣(qi)中非(fei)常(chang)活(huo)(huo)躍,只要本質比較活(huo)(huo)躍的(de)金(jin)屬材(cai)料都很容易和氧(yang)氣(qi)產生化學反應,但是(shi)(shi)經(jing)過鍍鋅之后就(jiu)(jiu)能(neng)夠起到保護作(zuo)用,這樣就(jiu)(jiu)不會發生氧(yang)化現象發生。
