Study on Degreasing Wash by Electrolyzed Oxidized Water for Cutting Surface of Carbon Steel

This paper describes degreasing washing performance for cutting surface of carbon steel by electrolyzed oxidized (anode) water of dilute sodium chloride solution instead of organic chloride solvents. First, the effect of corrosion on carbon steel by electrolyzed oxidized water was investigated. Next, as degreasing washing performance, efficiency of decomposition, solubility and emulsification of oil by electrolyzed oxidized water were demonstrated experimentally. Furthermore, investigation on the relationship between washing time and oil degreasing proceed, and comparison between the efficiency of cleanness by electrolyzed oxidized water and that by trichloroethylene on cutting surface of carbon steel were conducted. As results of the experiment, the electrolyzed oxidized water with controlled and optimized the washing process and the conditions was confirmed higher degreasing washing performance compared to the organic chloride solvent without doing any corrode to cutting surface of carbon steel, and it was concluded that the electrolyzed oxidized water could be applicable for degreasing washing solvent as replacement of the organic chloride solvents for cutting steel.
