摘要:
针对老通扬运河钢坝闸的服役环境,进行人工加速老化试验,从光泽度、色差、厚度、生锈面积4个方面研究防腐涂层的耐久性。结果表明:在老化前期,光泽度和色差值均变化明显且未出现生锈; 在老化中后期,涂层的生锈面积率随着试验时间呈不断上升趋势。在整个老化期间,涂层的厚度呈下降趋势。经过计算,钢坝闸防腐涂层的预期寿命为10.38 ～20.76年。
Abstract:
Aiming at the service environment of the old Tongyang Canal steel dam gate, an artificial accelerated aging test was carried out to study the durability of the anti-corrosion coating from four aspects: gloss, color difference, thickness, and rust area. The results showed that the gloss and color difference value changed significantly and no rust occurred in the early stage of aging, while the rust area rate of the coating showed a rising trend with the test time in the middle and late stages of aging. During the whole aging period, coating thickness decreased with the test time. The calculated life of anti-corrosion coating on steel dam gate was 10.38～20.76 years.
