长输埋地管道聚脲防腐涂层的应用研究
|
摘要
阐述了目前钢质埋地管道防腐涂层的种类和应用现状,分析了各自的优劣性。介绍了新型埋地管道防腐和补口材料用聚脲涂料,针对管道防腐涂层的技术要求,研究了聚脲涂层的力学性能、耐腐蚀性能以及耐老化性能。研究结果表明,聚脲具有优异的施工性能和防腐性能,适用于管道防腐和补口涂装。
The current anti-corrosive coating of the steel pipes and application status were described,the merits and demerits were analyzed.A new type of anti-corrosion material of buried pipelines and mending material with polyurea coating was introduced.According to the requirements of pipeline anti-corrosion coating technology,the mechanical properties of polyurea coating,corrosion resistance and anti-aging properties were studied.The results showed that the polyurea had construction property and excellent corrosion resistance,and it could be used in anti-corrosion and mending of pipes.
