摘要
为了解决大型桥梁钢箱梁的长效防腐蚀问题,以浙江舟山连岛工程西堠门大桥防腐蚀工程为依托,结合电弧喷涂防腐蚀技术和纳米改性封闭涂层技术,提出了电弧喷涂纳米封闭复合涂层体系的设计思路,对比了电弧喷涂长效防腐传统方案与创新设计方案,对不同腐蚀环境下推荐设计采用不同的电弧喷涂金属涂层材料,对比分析了纳米封闭涂层与普通环氧底层的技术指标,简述了电弧喷涂纳米封闭复合涂层施工各工序的质量要求和检测方法。
In order to solve the long-term corrosion problem for large-scale steel box girder bridges,this paper relies on Zhejiang Zhoushan Xihoumen Bridge,combining with arc spraying anti-corrosive coating technology and nano-modified sealing coating,the arc spraying nano sealing composite coating system was designed,comparing the conventional arc spraying composite coating system and innovative design solutions of arc spraying nano sealing composite coating system.Different arc spraying metal coating materials were recommended for different corrosive environments.The technical parameter comparison of nano sealer and common anti-corrosion epoxy primer were analyzed comparatively.Quality requirements and testing methods of arc spraying nano sealing composite coating system coating procedure arc briefly introduced.
