Eliminate oxidation scale with the power of liquid medicine and electricity. Remove it beautifully and evenly in a short time.
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.

Acid electrolytic treatment agents are specialized for the removal of oxidation scales and welding burns from metal surfaces, and are adopted in many industries where precision cleaning and appearance quality are emphasized. 【Main Application Examples】 ● Automotive Parts Manufacturing: Used for the removal of scales and burns after heat treatment of engine parts, exhaust system components, and muffler materials. Effective as a pre-treatment for subsequent plating and painting processes. ● Semiconductor Manufacturing Equipment and Piping: Removal of burns and discoloration from SUS piping and vacuum components. Enables surface finishing that maintains Ra and cleanliness. ● Architectural Hardware and Decorative Materials: Removal of burns and improvement of appearance for stainless steel handrails, panels, and outdoor structures. Contributes to a uniform glossy finish. ● Medical and Analytical Equipment: Scale removal from metal parts with hollow and complex structures. Achieves high cleanliness and reliability without processing unevenness. In these fields, it has realized quality stabilization and work efficiency that were difficult with conventional acid cleaning and manual methods, with many successful implementations.
Detailed information
-
Acid electrolytic treatment is an electrolytic cleaning technology that combines acidic solutions and electrical energy to quickly and uniformly remove oxide scale, welding discoloration, and oxide films adhered to metal surfaces. The metal to be treated (workpiece) is immersed in the electrolyte solution within the electrolytic cell, and direct current is passed between the electrodes, causing an electrolysis reaction. As a result of this reaction, oxygen gas is generated at the anode side and hydrogen gas at the cathode side, and these fine bubbles exert strong shear force and impact on the surface, physically detaching the scale and oxide films. Simultaneously, the acidic solution (mainly a mixture of inorganic acids and surfactants) chemically decomposes and dissolves the oxides, cleaning the surface chemically as well. In anode treatment, the metal surface dissolves in minute quantities, ensuring the complete removal of the oxide film and resulting in a smooth and glossy finish. In cathode treatment, scale and discoloration are removed through reduction effects and the detaching action of hydrogen. Furthermore, in PR (periodic polarity reversal) electrolysis, alternating the anode and cathode allows for more uniform and efficient treatment, preventing unevenness and excessive dissolution. Thus, acid electrolytic treatment is an advanced surface treatment technology that achieves precise and stable scale removal through the synergistic effects of physical, chemical, and electrical interactions.
