| 目 的 研究远地式辅助阳极发生电流单元的改变和距离 平台 的相对位置对平台 电位分布及保护程度的影响。 方法 以位于渤海湾 JZ120-1 在役导管架平台 为 原型, 构建了 一个 1 : 20 的缩比模型。 在平台 底部一定距离 处放置一座远地式辅助阳极, 研究恒电流下辅助阳极与 平台 底部间 距和辅助阳极发生电流单元的改变对平台 电 位分布及其保护程度的 影响。 结果 单座远地阳极即可实现对整座平台 的腐蚀控制。 辅助阳极距离 平台 越远, 平台 表面电 位差越小, 电 位分布越均匀 ; 辅助阳极距离 平台 越近, 单支阳极较四支阳极保护下的 平台 表面电 位差越大, 距离 越远, 电位差越小, 距离 相同 时,4 支阳极较单支阳极保护下的 平台 表面电 位差小, 电 位分布更均 匀 。 尽管海水稀释20 倍, 钙质沉积层的沉积与 覆盖仍是影响平台 表面电位分布的重要因 素。 结论 辅助阳极发生电流单元的数量、距离 平台 的相对位置以及钙质沉积层的覆盖是影响平台 表面电 位分布和保护程度的重要因 素。 |

| Objective To Study the effects of the change in current unit of the remote auxiliary anode and the spacing between the platform and the auxiliary anode on the distribution and protection of platform potential. Methods Based on the JZ120-1 jacket platform in the Bohai Bay, a 1 : 20 physical scale model was built. At the bottom of the experimental pool, a remote auxiliary anode was placed at a certain distance apart from the scale model. Under a certain protection current, the effects of the spacing between the platform and the auxiliary anode as well as the change in current unit of the remote auxiliary anode on the distribution and protection of platform potential were studied. Results The corrosion control of the whole platform can be realized by a single-seat remote anode. The farther the distance between the auxiliary anode and the scale model, the smaller the platform surface potential diffference, and the more even the potential distribution. The closer the distance between the auxiliary anode and the scale model, the greater the potential difference between one anode unit and four anode units, while the farther the distance, the smaller the potential difference. Comparing with the one unit, the four anode units showed a smaller platform surface potential difference and a more even potential distribution at the same distance. Although the experimental seawater was diluted 20 times by running water, the calcareous sediments and covering were still important factors affecting the potential distribution on the platform surface. Conclusion The current unit amount of the auxiliary anode, the spacing of the platform and the auxiliary anode, and the covering of calcareous sediments were important factors affecting the distribution and protection of the platform surface potential. |
