Stainless steel coloring not only gives stainless steel products a variety of colors, but also increase the variety of color products, improve the stainless steel color plate products wear resistance and corrosion resistance.
Stainless steel coloring methods are as follows:
1. Chemical oxidation coloring method
2. Electrochemical oxidation staining method
3. Ion deposition oxide coloring method;
4. High temperature oxidation coloring method
5. Gas phase decomposition coloring method.
A brief summary of the various approaches is shown below
1. Chemical oxidation coloring method: the color of a film formed by chemical oxidation in a specific solution, including dichromate method, mixed sodium salt method, vulcanization method, acid oxidation method and alkaline oxidation method.Inco is commonly used, but in order to maintain the color of the product, the stainless steel color plate must be controlled with reference electrode.
2. Electrochemical staining: the color of a film formed by electrochemical oxidation in a specific solution.
3. Ion deposition oxide coloring method chemical method: put the stainless steel color plate into the vacuum evaporation machine for vacuum evaporation.For example, the titanium case, the watchband is usually gold.This method is suitable for processing large quantities of products.Because the investment is very large, the cost is very high.
4, high temperature oxidation coloring method: in a specific molten salt, immersed in stainless steel color plate to maintain a certain process parameters, on the workpiece to form a certain thickness of the oxidation film, performance of various colors.
5. Gas phase decomposition coloring method: complex and rarely used in industry.
