摘要
通过粉末压片法制作了固体二氧化锰参比电极,室温下在模拟混凝土孔隙溶液中跟踪了电极开路电位和极差变化,并通过恒电流极化方法检测了电极抗极化性能。结果表明,所制作固体二氧化锰参比电极稳定性良好,重现性好,极化小。经过进一步的完善可以作为监测钢筋混凝土结构耐久性状况的传感器元件使用。
The solid manganese dioxide reference electrodes are fabricated by pushing powder in laboratory.The open-circuit potential,potential difference and polarization behaviour of sensors were examined in synthetic concrete pore solution at room temperature.The results show the electrochemical stability of sensors was well,the potential difference is little and the polarization behaviour of sensors is commonly.By further improving,the solid manganese dioxide reference sensor can be used to detect the durability o...
