Surface Treatment

 

1. Quality polishing

 

Quality polishing is a common surface treatment method, which can improve the corrosion resistance of stainless steel and avoid surface oxidation and corrosion. The technique involves the use of electrolytic polishing or pearlescent polishing machines, where the surface texture is removed by machine operation and a high gloss is formed on the surface.

 

2. Pickling

 

Pickling can remove surface dirt, oxidation and corrosion, providing a clean surface for the next step of processing. It is usually pickled with a solution of dilute nitric acid and dilute hydrofluoric acid of 5%-20% concentration, and then washed with water.

 

3. Mechanical polishing

 

Mechanical polishing is a mechanical finishing technique that easily removes surface defects such as potholes, oxides, and rust. The technology uses a wire brush and sandpaper to remove debris from the surface through high-speed rotation and high-speed vibration, making the surface smooth and smooth.

 

4. Sand blast

 

Sandblasting technology can improve the surface roughness, reduce the surface gloss, and make the material more textured and aesthetic. The technique is typically sprayed using steel balls and alumina powder.
