我省水利水电工程中的闸门,大部分是钢结构,在多年运行中,普遍存在闸门生锈的问题,严重的威胁着闸门的安全运行。如何采取有效的办法防止闸门锈蚀,各地都在探索。现介绍国内几种钢闸门防腐蚀的方法,供各地参考。一、腐蚀原理钢闸门在水中发生锈蚀的内在原因是它本身含有一定的杂质,造成材质结构上的差异,加上外界因素如闸门表面状态,溶液中离子浓度,溶解气体(氢、氧)的浓度,溶液温度,
In our province, water conservancy and hydropower projects in the gate, most of the steel structure, in many years of operation, the prevalence of rusty gate, a serious threat to the safe operation of the gate. How to take an effective approach to prevent gate rust, all over the exploration. Now introduce several kinds of domestic steel gate anti-corrosion method for reference. First, the corrosion principle Steel gate corrosion in water is due to the inherent reason it contains certain impurities, resulting in structural differences in materials, coupled with external factors such as the gate surface state, the ion concentration in solution, the dissolved gas (hydrogen, oxygen) Concentration, solution temperature,
