一、钢闸门的锈蚀与传统检测手段 众所周知闸门在防汛抗洪、排涝灌溉以及水力发电中起着重要作用。一旦出险将会造成巨大损失。钢闸门的锈蚀、碳化、穿孔是钢闸门常见的毛病,锈蚀、碳化程度是直接关系到闸门能否抗压防漏的重要参数,也是日常闸门检修的关键。钢闸门的锈蚀主是由于常年浸泡在水中,与水和氧产生反应形成电化腐蚀,主要方程式为:负极:Fe-2e=Fe~(2+),正极:2H_20+0_2+4e=40H~-。因为反应中有水与氧的共同作用,所以闸门的锈蚀的最主要部分是经常与水和氧接触频繁的地
First, the rust of steel gate and the traditional means of detection As we all know the floodgate in flood control, drainage irrigation and hydroelectric power play an important role. Once out of danger will result in huge losses. Steel gate corrosion, carbonation, perforation of steel gate is a common problem, rust, carbonization degree is directly related to the gate can compressive and leakproof important parameters, but also the key to daily gate maintenance. The main corrosion of steel gate is due to perennial immersion in water, and water and oxygen react to form electrochemical corrosion, the main equation is: negative: Fe-2e = Fe ~ (2+), positive: 2H_20 + 0_2 +4 e = 40H ~ . Because of the combined effect of water and oxygen in the reaction, the most important part of the corrosion of the gate is often in contact with water and oxygen frequently
