摘要

采用电化学方法对电厂回用水的腐蚀性进行了动态试验研究

并与传统试片法进行了比较。结果表明:电化学测量技术能即时和直观地反映回用水对实际系统管道的腐蚀特性

可用来客观真实评价回用水的腐蚀性

对指导回用水的防腐具有实际意义;传统试片法由于测量的是试验期间总的腐蚀结果

以及所用试片表面状态与实际系统管道表面状态不一致

因此所得试验结果不能完全反映回用水对系统的真实腐蚀性。

Abstract

The dynamic test study on corrosivity of re-utilizing water in power plants has been carried out by using the electro-chemical testing method

and a comparison with the traditional test specimen method being made.Results show that the application of the electro-chemical measurement method can timely and directly reflect the corrosivity of re-utilizing water to the pipeline in practical system

and can objectively and actually evaluate the corrosivity of the re-utilizing water

having practical significance for guiding the anti-corrosive treatment of re-utilizing water in the fields;whereas in traditional test specimen method

the result measured is the total corrosion

and during the time of test

the surface condition of the used specimen is not in consistancy with that in the pipeline of practical system

thus

the test results obtained can't fully reflect the actual corrosivity of re-utilizing water in the said system.
