涂層(ceng)鈦陽(yang)(yang)(yang)極(ji)(ji),習(xi)慣稱(cheng)為DSA(Dimensionally Stable An2ode尺寸穩定陽(yang)(yang)(yang)極(ji)(ji)),又稱(cheng)DSE(Dimensionally Stable Elec2trode),是(shi)20世紀60年代(dai)末(mo)發(fa)展起來的(de)一種新型不溶(rong)性(xing)(xing)陽(yang)(yang)(yang)極(ji)(ji)材料。傳(chuan)統的(de)陽(yang)(yang)(yang)極(ji)(ji)材料大致分為3類(lei):鉑金(jin)、石墨(mo)及鉛合金(jin)陽(yang)(yang)(yang)極(ji)(ji)。鉑金(jin)價格昂貴,石墨(mo)與(yu)鉛合金(jin)陽(yang)(yang)(yang)極(ji)(ji)高電(dian)流電(dian)解時發(fa)生溶(rong)蝕(shi),耐(nai)蝕(shi)性(xing)(xing)差,析氧電(dian)位(wei)大,電(dian)化(hua)學(xue)催化(hua)性(xing)(xing)能(neng)(neng)低,能(neng)(neng)耗較大,尤其是(shi)陽(yang)(yang)(yang)極(ji)(ji)中有毒的(de)鉛會在(zai)溶(rong)液中溶(rong)解,造成二(er)次(ci)污染,并且(qie)使鍍層(ceng)性(xing)(xing)能(neng)(neng)下降。DSA涂層(ceng)鈦陽(yang)(yang)(yang)極(ji)(ji)的(de)應用DSA涂層(ceng)鈦陽(yang)(yang)(yang)極(ji)(ji)主(zhu)要應用在(zai)電(dian)化(hua)學(xue)和電(dian)冶金(jin)兩大部門。
