       鈦(tai)基二氧(yang)化鉛(qian)電(dian)(dian)(dian)極(ji)(ji)(ji)有(you)析氧(yang)過電(dian)(dian)(dian)位高、氧(yang)化能(neng)力(li)強、耐腐蝕性能(neng)好、電(dian)(dian)(dian)導率好、在(zai)水(shui)溶液中(zhong)電(dian)(dian)(dian)解(jie)(jie)時能(neng)通過大電(dian)(dian)(dian)流等特點。它的化學穩定性好，硬度大，但機械強度差，易(yi)碎，在(zai)硫酸介質中(zhong)性能(neng)較(jiao)好。在(zai)電(dian)(dian)(dian)解(jie)(jie)工(gong)業中(zhong)用作不溶性電(dian)(dian)(dian)極(ji)(ji)(ji)。以下(xia)是鈦(tai)陽極(ji)(ji)(ji)廠家帶您了解(jie)(jie)鈦(tai)基二氧(yang)化鉛(qian)陽極(ji)(ji)(ji):

       鈦基二氧化鉛陽極在無機化工(gong)中的應用:

       1. 鹵代PbO2:電(dian)(dian)極(ji)在鹵代鹽(yan)工(gong)業中應用已很長時間(jian)。以PbO2為陽極(ji)，采(cai)用電(dian)(dian)化學技(ji)術(shu)合成了HC10。HC10的轉化率(lv)和電(dian)(dian)流效率(lv)較高。同時，低聚酸(suan)鹽(yan)和碘酸(suan)鹽(yan)的生產(chan)也是一項比較成熟(shu)的技(ji)術(shu)。20世紀80年代，PbO2電(dian)(dian)極(ji)已被用作陽極(ji)，HC10氧(yang)化產(chan)生HC10，其轉化率(lv)和電(dian)(dian)流效率(lv)都比較高。

       2. 電(dian)鍍PbO2電(dian)極耐(nai)H2SO4。耐(nai)腐(fu)蝕(shi)，適用于在Zn、Cu、Ni、C0等硫酸(suan)(suan)鹽電(dian)解液中精煉(lian)金(jin)屬。電(dian)極PbO2的(de)(de)陽極電(dian)位高于其他(ta)電(dian)極，具有(you)獨特(te)的(de)(de)氧化能(neng)力和(he)良好的(de)(de)耐(nai)腐(fu)蝕(shi)性能(neng)。可在電(dian)解工(gong)藝中作為(wei)陽極材(cai)料，如電(dian)解制造鉻酸(suan)(suan)、高氯酸(suan)(suan)鹽、鉻酸(suan)(suan)中鍍鉻等強酸(suan)(suan)溶液、電(dian)鍍硬鎘、鋼鐵工(gong)業中制造無錫細鋼絲等。

       鈦基二氧化(hua)鉛陽極在有機(ji)化(hua)工中的應用：

       在(zai)制備(bei)bitogen仿bitogen時，PbO2電(dian)(dian)(dian)極(ji)(ji)代替Pt電(dian)(dian)(dian)極(ji)(ji)的效(xiao)果更(geng)好，PbO2電(dian)(dian)(dian)極(ji)(ji)的電(dian)(dian)(dian)流效(xiao)率(lv)可(ke)達(da)到80% ~ 90%，轉化(hua)(hua)(hua)率(lv)可(ke)達(da)到98% ~ 99%，產(chan)品純度可(ke)達(da)到99.5% ~ 99.9%。與傳統方法(fa)相比，采用PbO2電(dian)(dian)(dian)極(ji)(ji)電(dian)(dian)(dian)化(hua)(hua)(hua)學(xue)氧化(hua)(hua)(hua)法(fa)制備(bei)異(yi)丁酸可(ke)顯著(zhu)降低生(sheng)產(chan)成(cheng)本(ben)和環境污(wu)染(ran)。同時，利用電(dian)(dian)(dian)極(ji)(ji)在(zai)酸性(xing)溶(rong)液中進(jin)行(xing)電(dian)(dian)(dian)解氧化(hua)(hua)(hua)合成(cheng)有機化(hua)(hua)(hua)合物。
