1. Mirror treatment
The mirror surface treatment of stainless steel is simply to polish the surface of the stainless steel. The polishing methods are divided into physical polishing and chemical polishing. Partial polishing can also be performed on the surface of stainless steel. The level of polishing is divided into ordinary polishing, ordinary 6K, fine grinding 8K, and super fine grinding 10K. The mirror surface gives people a sense of high-end simplicity and a fashionable future.
This is the most common surface treatment process for stainless steel processing. It is mainly powered by compressed air, and the high-speed jet beam sprays the spray material onto the surface of the workpiece to be treated, so that the shape of the outer surface of the workpiece changes.
Sand blasting is mainly used in engineering and surface technology, such as increasing the viscosity of bonding parts, optimizing machined surface burrs, decontamination and surface matte treatment. This process has a much better effect than manual sanding. The surface structure after sandblasting is uniform, which can create low-key and durable features of the product, and the production and processing efficiency is high. Manual sanding can make the rough surface but the speed is too slow, and the chemical solvent cleaning will clean the surface too smoothly, which is not conducive to coating adhesion.
3. Chemical treatment
This process mainly uses a combination of chemistry and electrochemistry to treat a layer of stable compounds formed on the surface of stainless steel. For example, the common electroplating in our lives is a kind of chemical treatment.
Chemical treatment mainly relies on singly or mixed acidic solutions, cationic solutions, etc. for rust removal. Afterwards, a protective film is formed on the metal surface by chromate treatment, phosphate treatment, anodic oxidation, blackening and other methods. This process is mainly used to produce complex pattern effects, to create retro or current design requirements.
4. Surface coloring
The surface coloring process of stainless steel can bring different colors to stainless steel, making the metal more colorful. Coloring not only makes stainless steel richer in appearance, but also can effectively improve the wear resistance and corrosion resistance of the product.
Commonly used surface coloring methods mainly include: chemical coloring method, electrochemical oxidation coloring method, ion deposition oxide coloring method, high temperature oxidation coloring method, vapor phase pyrolysis coloring method and so on.
5. Surface drawing treatment
Brushed metal processing is a very common decorative method in life. It can be made into straight grain, thread, corrugated, chaotic grain and spiral grain. This kind of surface treatment has the characteristics of good hand feeling, fine luster and strong abrasion resistance. It is widely used in electronic equipment, household appliances, mechanical equipment, etc.
Stainless steel spraying is substantially different from the above coloring treatment. Due to different materials, some spray paints may damage the surface oxide layer of stainless steel. However, some spraying can use simple processes to achieve different colors of stainless steel products, and different spraying can also be used to change the feel of stainless steel.
