Acid electrolytic treatment agents are high-performance pretreatment agents developed to remove oxide scale, discoloration, and oxide films that occur on metal surfaces such as stainless steel and titanium. By immersing the product in an acidic solution and applying an electric current, electrolysis occurs, generating fine gases of oxygen and hydrogen. These gases physically stimulate the work surface while simultaneously breaking down and removing oxides through chemical reactions with the solution. This combined action allows for the treatment of complex-shaped parts and fine recesses that are difficult to handle with manual pickling or chemical cleaning, achieving a uniform and stable finish in a short time. By incorporating surfactants and wetting agents, the re-adhesion of dirt is prevented, further improving cleaning efficiency. It supports anode, cathode, and PR electrolysis (periodic polarity reversal), allowing for flexible setting of optimal treatment conditions according to the material and type of scale. The metal surface after treatment is bright and smooth, making it compatible with subsequent processes such as passivation, painting, and plating. With a proven track record in fields such as automotive, construction, medical, electronic components, and precision machinery, acid electrolysis, which simultaneously achieves labor saving, quality stabilization, and process shortening, significantly contributes to the efficiency of on-site operations.
