Quelle est la différence entre le polissage électrolytique et le polissage chimique ? Traitement de surface des grilles en acier

During the production process of stainless steel grating, surface treatment is a very critical step.

Electropolishing

Principle: In the electrolyte, the microscopic raised areas on the metal surface are dissolved first by applying an external current, thus achieving a smooth and bright effect.

Advantages: The surface is more uniform and flat, effectively removing microscopic cracks and improving corrosion resistance.

Suitable for: Steel grating projects with high-end requirements, such as food, pharmaceutical, and chemical industries.

Cost: High equipment investment, but the best results, offering superior cost-effectiveness in the long run.

Chemical Polishing

Principle: Through the corrosive action of chemical solutions, the microscopic raised parts of the surface are dissolved first, achieving a certain degree of brightness.

Advantages: Simple operation, no power supply required, suitable for steel grating processing with complex shapes and large batches.

Suitable for: General drainage platforms, walkways, and ordinary industrial platforms.

Cost: Low initial investment, but surface brightness and durability are slightly inferior to electropolishing.

Summary:

If you have high requirements for corrosion resistance and surface precision, it is recommended to prioritize electropolishing;

If you prioritize efficiency, are cost-sensitive, and the use environment is general, chemical polishing can also meet daily needs.
