The common stainless steel surface treatment technology has the following treatment methods: surface color alism treatment, surface mirror light treatment, surface coloring treatment.
Surface natural al-bleaching treatment: stainless steel in the process of processing, through the coil plate, edge, welding or after artificial surface roasting heating treatment, resulting in black oxide skin. This hard gray-black oxide skin is mainly NiCr2O4 and NiF two EO4 components, previously generally used hydrofluoric acid and nitric acid for strong corrosion removal. But this method is expensive, pollutes the environment, is harmful to human body, corrosive, and is gradually eliminated.
Surface mirror light treatment method: according to the complexity of stainless steel products and user requirements can be different mechanical polishing, chemical polishing, electrochemical polishing and other methods to achieve mirror gloss.
Surface coloring treatment: stainless steel coloring not only gives stainless steel products a variety of colors, increase the variety of color products, but also improve product wear resistance and corrosion resistance.
Stainless steel processing method selection: stainless steel surface treatment selection of which method, according to the product structure, material, and different requirements for the surface, choose the appropriate method for treatment.
