这些金属阳极用于氯碱工业电解槽。在具有良好性能氧化钌——氧化钛涂层涂液组成的基础上,对于三组份、四组份的涂液配方与涂层电性能关系进行了研究。例如把铱、钯、铂、钴、锡等元素的氯化物加入含有三氯化钌和三氯化钛的涂液中作为制备涂层的催化活性成分,通过特定的工艺过程制备的各种涂层显示出优良的性能,它们具有与氧化钌——氧化钛涂层几乎相同的低的放氯电位,较高的放氧电位和较好的抗氧腐蚀性能。本文介绍了制备各种不同涂层的涂液配方和操作条件,以及有关涂层性能的测试数据。
These metal anodes are used in chlor-alkali industrial cells. Based on the composition of ruthenium oxide-titanium oxide coating with good performance, the relationship between coating formulation and coating composition of three components and four components was studied. For example, Iridium, palladium, platinum, cobalt, tin and other elements of the chloride is added to the coating solution containing ruthenium trichloride and titanium trichloride as a coating preparation of catalytically active components prepared by a specific process of coating The layers show excellent properties, they have almost the same low chlorine discharge potential as the ruthenium oxide-titanium oxide coating, higher oxygen evolution potentials and better oxygen corrosion resistance. This article describes the formulation and operating conditions for the preparation of coatings for various coatings, as well as test data on coating performance.
