涂層(ceng)鈦陽(yang)(yang)(yang)極(ji),習(xi)慣(guan)稱(cheng)(cheng)為DSA(Dimensionally Stable An2ode尺寸穩(wen)定陽(yang)(yang)(yang)極(ji)),又稱(cheng)(cheng)DSE(Dimensionally Stable Elec2trode),是20世紀60年(nian)代末(mo)發展起來的(de)(de)一種新型不(bu)溶性(xing)陽(yang)(yang)(yang)極(ji)材料。傳統的(de)(de)陽(yang)(yang)(yang)極(ji)材料大致分為3類(lei):鉑金(jin)(jin)(jin)(jin)、石(shi)墨(mo)及(ji)鉛(qian)合金(jin)(jin)(jin)(jin)陽(yang)(yang)(yang)極(ji)。鉑金(jin)(jin)(jin)(jin)價格昂貴,石(shi)墨(mo)與(yu)鉛(qian)合金(jin)(jin)(jin)(jin)陽(yang)(yang)(yang)極(ji)高電(dian)流(liu)電(dian)解時發生溶蝕,耐蝕性(xing)差,析氧電(dian)位大,電(dian)化學(xue)催化性(xing)能(neng)(neng)低,能(neng)(neng)耗(hao)較大,尤其是陽(yang)(yang)(yang)極(ji)中有毒(du)的(de)(de)鉛(qian)會在(zai)溶液(ye)中溶解,造(zao)成(cheng)二次污染,并且使鍍層(ceng)性(xing)能(neng)(neng)下(xia)降。DSA涂層(ceng)鈦陽(yang)(yang)(yang)極(ji)的(de)(de)應用DSA涂層(ceng)鈦陽(yang)(yang)(yang)極(ji)主要應用在(zai)電(dian)化學(xue)和電(dian)冶(ye)金(jin)(jin)(jin)(jin)兩大部門。
