| 摘 要： | 重点讨论了油罐的腐蚀机理,分析其腐蚀过程;介绍了在某滨海电厂油罐防腐设计及施工中各阶段合理地选用了一些新工艺、新技术、新材料;其次在技术方案中介绍了高压水喷砂的技术特点,以及这种技术应用于油罐环境的优点;通过分析所使用的防腐涂料其配方组成成分的特点:例如对环氧及其固化剂都进行了再聚合改性,不仅保留了环氧的聚合功能,而且增加了螯合功能,可以将钢铁表面残存的铁锈等杂质与钢铁基材一起螯合成结构稳定的大分子团;带潮功能也是这种涂料的技术特点,及这种涂料耐碱性与环氧相当,耐酸性有提高,耐中性盐雾试验长达10000小时,超过一般环氧树脂.文中介绍了一种适合油罐阴极保护的高效牺牲阳极,这种阳圾电流效率高,电位稳定,已经广泛应用于国内各类大型油罐.

| Abstract: | Following a survey on corrosion case of a heavy oil tank locate at sea coast area, the relevant corrosion mechanism was discussed and some corrosion control measures were also proposed to remedy the tank. The measures include high pressure liquid sandblast, new sacrifice anode material and new coating of expiry type etc., which were successfully used in the corrosion control engineering for large scale tanks. |
