水工闸门长期处于水下或在干湿交替的环境中使用,受到各种水质、水生物的侵蚀和泥沙、冰凌及其它漂浮物的冲击磨擦,极易腐蚀。因而降低了结构强度,减少了使用寿命。为了延长闸门的使用年限,确保闸门安全运行,必须对闸门采取有效的防腐措施。目前,各地采用的防腐办法多是采用油漆涂层保护,但仅能维持两三年,效果不理想。从 Hydraulic gate long-term underwater or in alternating wet and dry environment, subject to a variety of water quality, aquatic erosion and sediment, ice and other floating objects of the impact of friction, extremely corrosion. Thus reducing the structural strength and reducing the service life. In order to extend the service life of the gate, to ensure the safe operation of the gate, the gate must be effective anti-corrosion measures. At present, the anti-corrosion measures adopted all over the world mostly adopt the paint coating protection, but can only maintain two or three years with unsatisfactory results. From
