摘　　要：为了解除乙二醇型防冻液在舰船射频冷却管网系统中长期使用可能造成的腐蚀隐患,搭建一套模拟实船管网系统的腐蚀实验平台,对不同流速、不同运行时间后的管网管段进行腐蚀速率分析、腐蚀情况检测,对长期运行后的冷却液成分变化进行检测,结果表明,由于腐蚀作用,实验管段腐蚀速率大约为0.001~0.0025 mm/a,冷却液中Fe、Ni等管网材料典型元素离子浓度显著提升,悬浮颗粒数量显著提升。In order to study the corrosiveness of ethylene glycol antifreeze to ship RF cooling pipe network system,a small experiment platform modeling the real ship system was set up.The corrosion rate and effect were detected for pipe network sections with different flow rates and operation time,as well as changing of the coolant composition after long-term operation.It was shown that after two months to six months running,the corrosion rate of the experimental pipe segment was about 0.001~0.0025 mm/a,the concentrations of Fe and Ni ions and the quantity of suspended particulates in ethylene glycol solution after long term running are increased.
