简介:摘要钢结构具有自重轻、抗震性能好、节能效果好、工业化程度高等一系列优点,被广泛的应用于火力发电厂,如果钢结构长期处于海洋大气、工业大气腐蚀环境下,会造成钢结构快速腐蚀,不仅浪费资源,同时也给结构安全带来隐患。锌加涂膜镀锌有效地结合了热镀锌锌层的主动阴极保护和有机涂料的屏障保护,对钢铁具有长效的优异防腐保护性能,特别适用于恶劣腐蚀环境下的钢结构防腐。但是锌加防腐施工对于钢结构表面处理,钢材表面盐分、粗糙度,喷涂工艺要求极为苛刻,受环境温度、空气湿度影响较大,现场施工难度较大。本文对“C5-M”腐蚀级别下钢结构锌加防腐施工技术进行了研究,为钢结构锌加防腐施工以及普通钢结构的喷砂防腐提供技术支持。
