The metal decorative mesh you usually see are bright and beautiful, and one of the processes used is electrolytic polishing. Today, qunkun metal manufacturer will explain to you how to electrolytically polish the surface of metal decorative mesh.
First: We start with the combination of the characteristics of stainless steel. From the perspective of aesthetics and corrosion resistance, we should make the stainless steel metal mesh appear bright and clean after cleaning and polishing.
Second: The chromium in the stainless steel combines with the oxygen in the air. This layer of chromium oxide protects the stainless steel material itself through further corrosion. Various pollutants prevent the oxide layer from further developing the protective material, and try to make the stainless steel material attack .
Third: The nitric acid or citric acid process (passivation) enhances the formation of an oxide layer on the surface of the stainless steel which allows the optimal "passive" state. , So that the metal is particularly bright.
