摘要
金属罐底板外侧的腐蚀较严重,采用传统的阴极保护方法必须设置绝缘法兰,而最新研究的阴极保护方法,是用固体电解质外加电流阴极保护原理,对罐底板进行阴极极化,并将极化电位控制在某一定值,达到减缓或抑制腐蚀的目的,而且可以免除绝缘法兰的设置。
It is normal that the outside of metal tank bottom plate is seriously corroded and that the insulated flanges must be installed by the traditional method of cathodic protection. However, recent study shows that the solid electrolyte with impressed current is available for use in the principle of cathodic protection, and that the tank bottom plate is being cathodically polarized. By this way, the purpose of retarding or controlling corrosion could be achieved with polarized potential controlled at a setting value and the installation of insulated flange could be eliminated.
