一种输电铁塔用高适应性防腐涂料的研制和应用

Research and Application of a Highly Adaptable Anticorrosion Coating for Transmission Tower

在重污染工业区、尾气排放量较高的市区以及沿海地区,大部分输电铁塔塔件的镀锌层几年即出现部分或完全腐蚀。为提高输电设备在此环境下的运行寿命,研制了一种高耐候长寿命防腐涂料,这种涂料可阻隔腐蚀介质到达锌层表面发生电化学腐蚀,解决镀锌构件在特殊气候条件下的腐蚀问题。另外,该涂层对带锈锌、锈蚀钢材、旧有涂层同样具有良好的兼容性,是一种提高输电安全性、降低户外维修成本的有效方法。

In heavy pollution industrial site, high emissions urban and coastal areas, most of the galvanized pieces are partially or totally corroded. In order to prolong the operating life of transmission equipment in those environments, an anticorrosive coating of high weather resistance and long service life is developed, the coating can prevent corrosive medium from reaching the surface of zinc layer and thus eliminate the occurrence of electrochemical corrosion, the method can solve the corrosion problems of galvanized component in special corrosive environments. In addition, the coating also has good compatibility with rust zinc, rust steel and aged coating etc., therefore, which is an effective means to enhance the safety of power transmission, while reduce the cost of outdoor maintenance.
