Analysis of Corrosion Protection Effect of Concentrated Liquid of Mine Hydraulic Support
In order to analyze the anti-corrosion effect of concentrated liquid on hydraulic support,the method of analysis and comparison test was used to use mine water and diluent liquid with a mass concentration of 3％of the proportion of mine water and concentrated liquid for metal immersion.After observation of metal surface microstructure,electrochemical reaction analysis,analysis of changes in polarization voltage and polarization current,and analysis of changes in elements in metal specimens,the test results showed that the uniform corrosion inhibition rate of the metal surface can reach 99.27％after immersion with 3％mass ratio concentrated liquid,which has a remarkable anti-corrosion effect.
