Coloring The method adopted is mainly the acid bath oxidation coloring method, which makes the stainless steel surface produce a transparent chrome oxide film. When the light shines on it, different colors will be generated due to the different thicknesses of the film. The whole process of color processing of stainless steel includes two steps: color treatment and dura treatment. The coloring process is carried out in a hot chromium sulphuric acid bath.
After immersion in the stainless steel, a layer of one percent thick oxide film with only one hair diameter will be formed on the surface. As time goes on and the thickness of the oxide film increases, the color of the stainless steel surface also changes. When the oxide film thickness increases from 0.2 microns to 0.45 m, the surface color of stainless steel will appear blue, gold, red, and green in turn.
By controlling the impregnation time, the rose gold stainless steel plates can be obtained. After the treatment of the dura, chromium oxide can be formed on the cathode. The stable compound, such as chromium hydroxide, not only fills the tiny pores in the oxide film, but also improves the wear resistance, corrosion resistance, and heat resistance of the oxide film so that the material becomes both beautiful and corrosion-resistant.
Application The new material rose gold stainless steel sheet has a wide application field, it can be used in elevators, hardware appliances, kitchen and toilet appliances, cabinets, building decorations, advertisement signs, daily necessities, and so on. It can greatly increase the added value of products and has obvious market competitive advantages. Colored stainless steel, color titanium black, sky blue, titanium gold, gem blue, purple, bronze, bronze, champagne gold, rose gold, purple-red, titanium white, green, and so on.
