The main difference between stainless steel polished and matte is that the brightness is different, the roughness is different, and the visual presented is different.
1, the brightness is different
Polished is like a mirror, can reflect the object, and matte called pull yarn or brushed, is the stainless steel surface layer like a steel wire ball scratched, low reflectivity.
2, the roughness is different
Polished roughness is very low, but the roughness of the matte is higher, more resistant to wear and tear, not easy to see wear and tear.
3, presenting different visual
Polished is a polished surface, reflecting light specular reflection, there is a glare, giving a person a bright and gorgeous feeling; matte no glare, not blinding, giving a person a feeling of stability and elegance.

How to polish
How to polishA, mechanical polishing: mechanical polishing is to rely on cutting, plastic deformation of the surface of the material to be polished after the removal of the convex part of the polishing method to get a smooth surface, the general use of oleander strip, wool wheel, sandpaper, etc., mainly hand-operated, special parts such as rotary surface, you can use the rotary table and other aids, the surface quality of the requirements of the high quality of the surface can be used in the ultra-precision research and polishing methods. The use of this technology can achieve Ra0.008μm surface roughness, is the highest in a variety of polishing methods. Optical lens molds often use this method.
Two, chemical polishing: chemical polishing is to let the material in the chemical medium surface microscopic convex part of the concave part of the preferential dissolution, so as to get a smooth surface. The main advantage of this method is that it does not require complex equipment, can be polished complex shape of the workpiece, can be polished at the same time a lot of workpieces, high efficiency. The core problem of chemical polishing is the preparation of polishing solution. Chemical polishing to get the surface roughness is generally a few 10μm.
Three, electrolytic polishing: electrolytic polishing and chemical polishing of the same basic principle, that is, by the selective dissolution of the material surface of the tiny protruding parts, so that the surface is smooth. Compared with chemical polishing, can eliminate the influence of cathodic reaction, the effect is better. Electrochemical polishing process is divided into two steps:
1, macroscopic leveling Dissolution products to the electrolyte diffusion, the material surface geometric roughness down, Ra>1μm.?
2. Microlight leveling Anodic polarization, surface brightness increases, Ra<1μm.
