As a building material widely used in various fields, stainless steel has a particularly important anti-rust treatment on its surface. In order to ensure the service life and aesthetics of stainless steel, we need to carry out effective anti-rust treatment on its surface. This article will introduce you to a commonly used stainless steel surface treatment method: the application of electrolytic polishing slurry.
First, the role of electrolytic polishing liquid.
Electrolytic polishing slurry is a chemical solution specially used for the surface treatment of stainless steel, which is mainly composed of the following components: phosphoric acid, sulfuric acid, etc. These components will produce a strong redox reaction during the electrolysis process, which will change the microstructure of the stainless steel surface, so as to achieve the purpose of improving the surface hardness, wear resistance and corrosion resistance.
Second, the use of electrolytic polishing liquid.
1.Cleaning: First of all, the surface of stainless steel needs to be thoroughly cleaned to remove impurities such as oil and dust on the surface. This step is crucial for the subsequent polishing results.
2.Coating: Apply the electropolishing liquid evenly to the surface of the stainless steel and wipe it evenly with a soft cloth to ensure that the liquid can fully penetrate the surface.
3.Electrolytic polishing: The coated stainless steel workpiece is placed in a special electrolytic cell and polished by direct current. During the electrolysis process, the acids in the polishing slurry react with the metal surface to form a dense oxide film, which improves the corrosion resistance and fingerprint resistance of the stainless steel.
4.Cleaning: After polishing, rinse the polishing liquid on the surface of the workpiece with clean water to avoid secondary pollution caused by liquid residue.
3. Advantages of electrolytic polishing slurry.
1.Improve the hardness and wear resistance of stainless steel surfaces and extend their service life.
2.Effectively reduce fingerprints and oxidation spots on the surface of stainless steel, and maintain its original luster.
3.It has strong corrosion resistance and is suitable for a wide range of environmental conditions.
4.It is easy to operate, does not require professional equipment and technology, and is suitable for production and processing of various scales.
