输变电设备用水性涂层体系防护性能演变规律研究
Study on Protection Performance Evolution Law of Waterborne Coating for Power Transmission and Transformation Equipment
摘要
Abstract
With the rapid development of the power industry,the operational reliability of power transmission and transformation equipment is facing a severe test.The neutral salt spray test was used to study the environmental adaptability and protective performance evolution of a water-based anti-corrosion coating system.The system was composed of water-based zinc-rich primer,water-based epoxy intermediate coating with cloud iron,and water-based polyurethane topcoat.The results showed that during the test period,the mechanical properties of the coating system had a small loss.After 1 000 h of the test,its pull-off adhesion and coating impedance were still 7.2 MPa and 108 Ω·cm2,with no bubbling or cracking on the surface,which remained smooth.Overall,the water-based coating system demonstrated good compatibility and environmental adaptability,providing effective protection for metal components of power transmission and transformation equipment.关键词
