惠州(zhou)酸(suan)洗鈍(dun)(dun)(dun)化(hua)(hua)(hua)無縫(feng)鋼管的(de)機理：我們知道，鐵、鋁在(zai)稀(xi)HNO3或稀(xi)H2SO4中(zhong)能很快溶解(jie)，但在(zai)濃(nong)(nong)(nong)HNO3或濃(nong)(nong)(nong)H2SO4中(zhong)溶解(jie)現(xian)象幾乎停止了，碳鋼通常很容易生銹(xiu)，若在(zai)鋼中(zhong)加入適量(liang)的(de)Ni、Cr，就(jiu)成為(wei)不銹(xiu)鋼了。金(jin)屬(shu)或合金(jin)受一些(xie)因素(su)影響，化(hua)(hua)(hua)學性明顯增強的(de)現(xian)象，稱為(wei)鈍(dun)(dun)(dun)化(hua)(hua)(hua)。　　由某(mou)些(xie)鈍(dun)(dun)(dun)化(hua)(hua)(hua)劑(化(hua)(hua)(hua)學)所引(yin)起的(de)金(jin)屬(shu)鈍(dun)(dun)(dun)化(hua)(hua)(hua)現(xian)象，稱為(wei)化(hua)(hua)(hua)學鈍(dun)(dun)(dun)化(hua)(hua)(hua)。如濃(nong)(nong)(nong)HNO3、濃(nong)(nong)(nong)H2SO4、HClO3、K2Cr2O7、KMnO4等氧化(hua)(hua)(hua)劑都(dou)可(ke)使金(jin)屬(shu)鈍(dun)(dun)(dun)化(hua)(hua)(hua)。金(jin)屬(shu)鈍(dun)(dun)(dun)化(hua)(hua)(hua)后，其(qi)電(dian)極電(dian)勢向(xiang)(xiang)正方向(xiang)(xiang)移動，使其(qi)失去了原有(you)的(de)特性，如鈍(dun)(dun)(dun)化(hua)(hua)(hua)了的(de)鐵在(zai)銅鹽中(zhong)不能將銅置換(huan)出(chu)。
