本文通过涂漆钢板的动态腐蚀、大气暴露试验三年多情况,分析总结了环境、除锈表面处理工艺、涂装、钢材材质对耐蚀性能的影响;从而提出铁道车辆防腐工作的重点在于采取相应措施,如采用耐候钢,建立钢板预处理生产线,严格掌握涂装工艺,保证漆膜厚度等。 This article through the dynamic corrosion of painted steel, atmospheric exposure test for more than three years, analyzed and summarized the environment, rust surface treatment technology, painting, steel material on the corrosion resistance; thus put forward the railway vehicle corrosion focus is to take Corresponding measures, such as the use of weathering steel, the establishment of pre-treatment plate production line, strictly control the coating process to ensure that the film thickness.
