       1.技術特點:抗(kang)菌(jun)腐蝕性能優(you)異;電極使用(yong)壽命(ming)長;可跟隨電流(liu)密度(du)高，電流(liu)效率高。工作電流(liu)密度(du):10000A /M2屬于工業(ye)純鈦為(wei)基礎的析氧型(xing)陽極。

       2.高催化(hua)活性:鍍(du)鉑(bo)電(dian)(dian)極(ji)是(shi)一種(zhong)眾所周知(zhi)的(de)高過氧電(dian)(dian)位電(dian)(dian)極(ji)(1.563V vs硫(liu)酸亞汞)。MMO陽(yang)極(ji)是(shi)一種(zhong)低析(xi)氧電(dian)(dian)極(ji)，相對于硫(liu)酸亞汞為1.385V。MMO陽(yang)極(ji)的(de)析(xi)氧區(qu)更容易析(xi)氧。因此，電(dian)(dian)解時(shi)，電(dian)(dian)池電(dian)(dian)壓相對較低，更節(jie)能。這(zhe)種(zhong)現象(xiang)在銅箔處理后的(de)堿性鍍(du)銅壁上(shang)已經(jing)明顯(xian)體現出來。

       3.沒有污染。MMO氧化物是一種相當穩定的氧化物，陽極涂層是貴金屬銥的陶瓷氧化物。幾乎不溶于任何酸和堿，且鍍層的總氧化量約為20-40 μm，因此，MMO鈦陽極不會對電(dian)鍍溶液造成污染，這(zhe)點與鉑(bo)電(dian)極基本相同。

       4.高性(xing)價比:MMO陽極(ji)的(de)價格(ge)約為鉑電(dian)極(ji)的(de)80%。MMO電(dian)極(ji)在(zai)堿性(xing)電(dian)鍍銅電(dian)解液中具(ju)有(you)較好(hao)的(de)電(dian)化學穩定(ding)性(xing)，并保持了與鉑電(dian)極(ji)(鍍層(ceng)厚度為3.5mm)相(xiang)同的(de)使(shi)用(yong)壽命。它還(huan)具(ju)有(you)優(you)良(liang)的(de)電(dian)解活(huo)性(xing)和耐久性(xing)。

       5.硫酸電(dian)解質中的(de)氯存在于當前(qian)的(de)環境(jing)中。尺寸穩定陽極的(de)使用防止了這種(zhong)現象，并使不溶(rong)陽極技術在此應用中取(qu)得了成(cheng)功的(de)性能(neng)優勢。

       6.陽(yang)極(ji)棒維護極(ji)少。不需要停止生產清洗和(he)補充陽(yang)極(ji)，更換陽(yang)極(ji)袋，重新涂陽(yang)極(ji)(提高生產率(lv)，降低人工(gong)率(lv)。

       7.不(bu)溶性陽(yang)極的壽命(ming)取(qu)決于類型、工作電(dian)(dian)(dian)(dian)流(liu)(liu)密度(du)(du)(du)(du)(du)和與(yu)各(ge)種電(dian)(dian)(dian)(dian)鍍(du)化學(xue)品的接觸。因為銅離(li)子傾向于集中(zhong)在(zai)(zai)孔(kong)的邊緣(高(gao)電(dian)(dian)(dian)(dian)流(liu)(liu)密度(du)(du)(du)(du)(du)區)并迅速積(ji)累(lei)(lei)，而孔(kong)的中(zhong)心部分(低電(dian)(dian)(dian)(dian)流(liu)(liu)密度(du)(du)(du)(du)(du)區)積(ji)累(lei)(lei)相對緩慢。這導致(zhi)了銅沉積(ji)非(fei)常不(bu)均勻的分布(bu):這種行為被(bei)稱(cheng)為“狗骨”，在(zai)(zai)中(zhong)等電(dian)(dian)(dian)(dian)流(liu)(liu)密度(du)(du)(du)(du)(du)時(shi)發(fa)生(sheng)(sheng)，在(zai)(zai)較低電(dian)(dian)(dian)(dian)流(liu)(liu)密度(du)(du)(du)(du)(du)時(shi)發(fa)生(sheng)(sheng)管裂，在(zai)(zai)較高(gao)電(dian)(dian)(dian)(dian)流(liu)(liu)密度(du)(du)(du)(du)(du)時(shi)發(fa)生(sheng)(sheng)燃燒。這對電(dian)(dian)(dian)(dian)鍍(du)電(dian)(dian)(dian)(dian)路(lu)板無疑是一個沉重的沖擊。采用鉑(bo)鈦不(bu)溶陽(yang)極在(zai)(zai)硫酸電(dian)(dian)(dian)(dian)解(jie)液中(zhong)，反向脈沖電(dian)(dian)(dian)(dian)鍍(du)陽(yang)極也(ye)誕生(sheng)(sheng)。隨著時(shi)間的推移(yi)，這種電(dian)(dian)(dian)(dian)流(liu)(liu)中(zhong)氯的存在(zai)(zai)將(jiang)剝離(li)鉑(bo)層。
