Publish Time: 2024-11-12
304 Stainless Steel Sink Cabinet is widely used in homes and commercial kitchens due to its excellent corrosion resistance, aesthetics and durability. In order to further enhance its corrosion resistance, the surface treatment process plays a key role.1. Polishing processMechanical polishing: Through mechanical polishing, the stainless steel surface forms a smooth mirror effect, reduces the surface roughness, and prevents the adhesion and deposition of corrosive media.Chemical polishing: Use chemical solutions to treat the stainless steel surface, remove tiny oxides and impurities on the surface, improve the surface smoothness and finish, and enhance corrosion resistance.Electrolytic polishing: Through the electrolytic polishing process, anodizing is performed in the electrolyte to further improve the surface finish and uniformity, and reduce the contact area between the corrosive medium and the metal surface.2. Passivation treatmentChemical passivation: Through chemical passivation treatment, a dense oxide film (passivation film) is formed on the surface of stainless steel, which prevents the metal from direct contact with the external corrosive medium and greatly enhances the corrosion resistance.Electrochemical passivation: Using electrochemical methods, stainless steel is anodized in the electrolyte to form a thicker and denser passivation film to improve corrosion resistance.Passivation layer stability: The passivation layer on the stainless steel surface after passivation treatment has high stability and durability, and can maintain a good corrosion resistance for a long time.3. Sandblasting processSurface roughening: Through the sandblasting process, the stainless steel surface forms a uniform micro-roughness, increases the surface area, and improves the adhesion of the coating and plating.Clean surface: The sandblasting process can effectively remove surface oxides, rust and other impurities, keep the surface clean and fresh, and enhance corrosion resistance.Matte effect: The stainless steel surface after sandblasting presents a matte effect, which has good visual effects and touch, while enhancing corrosion resistance.4. Coating treatmentAnti-fingerprint coating: Anti-fingerprint coating is applied on the surface of stainless steel to reduce the adhesion of fingerprints, grease and stains, keep the surface clean and enhance corrosion resistance.Anti-corrosion coating: By applying anti-corrosion coatings such as epoxy resin, polyurethane, etc., the contact between metal and corrosive media is further isolated to improve corrosion resistance.Multifunctional coating: Some coatings not only have anti-corrosion functions, but also have various properties such as anti-scratch, wear resistance and high temperature resistance, which comprehensively improves the service life and safety of stainless steel sink cabinets.5. Laser treatmentSurface modification: Use laser technology to modify the surface of stainless steel, change the surface microstructure and chemical composition, and enhance corrosion resistance.Texture processing: Through laser processing, specific textures and patterns are formed on the surface of stainless steel to improve the aesthetics and anti-slip properties of the surface, while enhancing corrosion resistance.Precision processing: Laser processing can achieve high-precision surface processing, ensure the uniformity and consistency of the processing effect, and improve the overall corrosion resistance.6. Heat treatmentSolution treatment: Through high-temperature solution treatment, the stress and grain boundary segregation inside the stainless steel are eliminated, and the uniformity and corrosion resistance of the material are improved.Aging treatment: Aging treatment is carried out after solution treatment to further stabilize the microstructure of the material and enhance the corrosion resistance.Combination of heat treatment: Through the combination of heat treatment with surface treatment processes such as polishing and passivation, the corrosion resistance and mechanical properties of the stainless steel sink cabinet are comprehensively improved.Through the comprehensive application of various surface treatment processes such as polishing, passivation, sandblasting, coating, laser treatment and heat treatment, the corrosion resistance of 304 Stainless Steel Sink Cabinet has been significantly enhanced. These treatment processes not only improve the surface finish, wear resistance and aesthetics, but also further isolate the contact between the metal and the corrosive medium, forming a stable protective layer, ensuring that the stainless steel sink cabinet can maintain excellent corrosion resistance and service life under various environmental conditions.
