【摘要】：在电解二氧化锰体系中,使用的阳极板通常具有易变型,电流密度低,电耗高等缺点。为了解决这些问题,文中选用工业纯钛作为基体,二氧化锰和二氧化锡作为复合活性涂层,采用简易的热分解方法制备出钛基复合涂层阳极。通过SEM测试涂层表面形貌,发现该阳极的涂层致密、呈较平整的层状。采用循环伏安曲线测试并计算积分面积和极化曲线对涂层配方进行研究,发现烧结温度为450℃,锡/锰比为6∶4时的阳极性能最优。与铅阳极和铅银合金阳极对比,用该复合涂层阳极电解得到的二氧化锰纯度更高,但其槽压比其它阳极低了约0.2 V左右,电流效率得到了提高,从而节约了电解过程中的能耗。因此,该复合涂层阳极适合做大型电极的阳极板。
[Abstract]:In electrolytic manganese dioxide system, the anode plate usually has the disadvantages of easy variation, low current density and high electricity consumption. In order to solve these problems, the titanium based composite coating anode was prepared by a simple thermal decomposition method with manganese dioxide and tin dioxide as composite active coatings. The surface morphology of the coating was measured by SEM, and it was found that the coating of the anode was compact and smooth. The formula of the coating was studied by measuring the cyclic voltammetry curve and calculating the integral area and polarization curve. It was found that the anode performance was the best when sintering temperature was 450 鈩，
