摘要:

?随着我国对海洋资源的开发,海洋钢结构的腐蚀控制技术越来越受到关注。海洋环境可以分为海洋大气区、浪花飞溅区、海水潮差区、海水全浸区和海底泥土区等五个腐蚀区带。其中,海洋钢结构在浪花飞溅区腐蚀最为严重。在浪花飞溅区,钢表面受到海水的周期性润湿,处于干湿交替状态,氧供应充分,盐分不断浓缩;加之阳光、风吹和海水环境等协同作用导致发生最严重的腐蚀。锈层的自氧化反应是加速钢结构在浪花飞溅区腐蚀的一个主要原因。复层矿脂包覆防腐技术是当前海洋钢铁设施浪花飞溅区防腐蚀应用较为理想的方法。

Abstract:

With the development of marine oil and gas exploration, more and more attention has been given to marine corrosive environment during the last decades. Marine corrosion environments are generally divided into atmospheric, splash, tidal, immersion, and mud zones. The protection against splash zone corrosion should be conducted with high priority. Aside from seawater that causes normal marine corrosion, other factors such as temperature variations, tidal action, wave impacts, man-made pollutants, sufficient oxygen (O2), ultraviolet rays, and salt spray that continually washes upon objects, cause severe corrosion damage in the splash zone. Note that rust self-oxidation greatly account for the corrosion of steel structures in the splash zone. PTC is the most useful technology to protect the steel in splash zone.
