1 鸭河口水库水工钢结构防腐蚀现状新溢洪道、老溢洪道,左、右岸进、出口闸门及其附属设施和水电站部分的金属构件共同构成了鸭河口水库水工钢结构的防腐体系。总防腐面积近两1万 m~2,由于设备的运用条件和工作环境不同,造成了腐蚀种类的多样性。1.1 涂料选用及配套1.1.1 溢洪道背水面、室内外设备等以大气腐蚀为主的钢结构选用耐侯性强的红丹防锈底漆和醇酸面漆配套使用,漆膜厚
1 Corrosion Protection of Hydraulic Steel Structures of Duhekou Reservoir The new spillway, old spillway, left and right bank in and out of the gate and its ancillary facilities and the metal components of the hydropower station constitute the corrosion protection system for the hydraulic steel structure of Yahekou Reservoir. Total anti-corrosion area of nearly two 10000 m ~ 2, due to equipment use conditions and work environment, resulting in the diversity of corrosion types. 1.1 Selection of paint and matching 1.1.1 spillway back to the surface, indoor and outdoor equipment to atmospheric corrosion-based steel structure selection of weathering strong Hongdan rust primer and alkyd finish supporting the use of film thickness
