聚氨酯材料在有轨电车嵌入式轨道防腐中的应用研究

Application of polyurethane material in embedded track corrosion prevention of modern tram

现代有轨电车嵌入式轨道的腐蚀是致使钢轨伤损和失效的重要原因之一,尤其是在绿化区段,腐蚀成为影响钢轨安全使用性能的主要因素。针对沈阳现代有轨电车嵌入式轨道存在的钢轨腐蚀问题,分析其产生的原因和危害,提出一种有效的聚氨酯防腐方案。该方案通过室内试验研究,取得了初步成果,并在沈阳南站选取试验段进行了铺设验证,效果良好。

Corrosion of the embedded track of the modern tram is one of the important factors causing rail damage and failure,especially in the green section,and corrosion has become the main factor affecting the safe use performance of rail.In view of the rail corrosion problems existed in the embedded track of Shenyang modern tram,the cause and harm of the rail corrosion are analyzed,and this paper puts forward an effective polyurethane anticorrosion solution.Through the laboratory test,the preliminary results have been obtained,and the test section has been laid and verified in Shenyang South station.The result is positive.
