How to remove oil, rust, and oxides from metal surfaces: Ethanolamine ester (polyurethane), EPO, can be used to formulate metal cleaning agents; it is effective in removing oil, rust, and oxides from metal surfaces and is suitable for various types of metals. Due to its foam-free properties, it is particularly suitable for foam-free or low-foam spray cleaning processes, such as the cleaning of automotive parts and mechanical components. It can be used at room temperature or under heated conditions without damaging the metal surface. It can also be used for grinding and polishing metal surfaces, helping to remove impurities generated during the polishing process and resulting in a smooth, spot-free metal surface.
To remove oil, rust, and oxides from metal surfaces, the following measures can generally be taken: 1. Removing oil: – Use specialized cleaning agents formulated with ethanolamine ester (polyurethane) EPO to remove oil through soaking, ultrasonic treatment, or spraying. - The formulated cleaner has low-foaming or non-foaming properties, making it ideal for spray cleaning. It is suitable for industries such as automotive and machinery parts. - It can be used at room temperature or with moderate heating, offering high cleaning efficiency. 2. Removing rust and oxides: – Acid pickling method: Soaking in acid solutions such as dilute hydrochloric acid, sulfuric acid, phosphoric acid, or citric acid, with a corrosion inhibitor added, to remove surface rust and oxides. - Chemical cleaning agent method: A specialized compound containing EPO is used, which can effectively remove mild rust and oxidation layers without damaging the metal substrate. - Mechanical treatment: Severe rust and oxidation layers are removed by sanding, wire brushing, or sandblasting; using an EPO cleaner in conjunction with this process yields even better results. 3. Surface grinding and polishing: – For metal surfaces that require high precision and brightness, these processes can be combined with grinding and polishing; ethanolamine ester (polyurethane) EPO cleaners can be used to remove the impurities resulting from grinding, thereby increasing the brightness of the metal surface. In summary, ethanolamine ester (polyurethane) EPO is an effective and safe metal surface cleaner, widely used for removing oil, rust, and oxides from metal surfaces, as well as for the cleaning and care of surfaces after grinding and polishing. .
