摘要
文章介绍了网状阳极在茂名、湛江、岚山和上海地区的大型储罐阴极保护系统的应用情况。从实际运行的结果看,罐底板的保护电位都达到了设计要求和标准规定,保护电位分布相当均匀。保护电流密度也满足了设计要求。保护效果较好,表明网状阳极对于大型储罐的外底板的阴极保护是一种较好的解决方案。对于发现的几个问题也作了讨论。
The applications of MMO (mixed metal oxide) grid anodes to large-scale storage tanks in Maoming, Zhanjiang, Lanshan and Shanghai are summarized. From the practical results, the protection potentials and protection current densities meet the design requirements and are in accord with technical standards. The distribution of protection potentials on the tank bottom is quite uniform. It indicates that the grid anode system is effective for the large-scale storage tank protection from corrosion. Other problems encountered are also discussed.
