Stainless steel coloring not only gives stainless steel products a variety of colors, but also increase the variety of products, improve the wear resistance and corrosion resistance of stainless steel color plate products.
About the color of stainless steel decorative plate coloring method mainly has the following:
1. Chemical oxidation coloring method
2. Electrochemical oxidation staining method
3. Ion deposition oxide staining method;
4. Oxidation coloring at high temperature
5. Gas phase decomposition and coloring method.
A brief summary of the various methods is shown below
1. Chemical oxidation coloring method: the color of the film formed by chemical oxidation in a specific solution, including dichromate method, mixed sodium salt method, sulfide method, acid oxidation method and basic 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 a reference electrode.
1, electrochemical staining method: in a specific solution, is the color of the film formed by electrochemical oxidation.
3. Ion deposition oxide staining chemical method: stainless steel color plate is put into the vacuum evaporation machine for vacuum evaporation. For example, titanium plated case, the strap is generally gold. This method is suitable for mass production. Because of the large investment, the cost is very high, a small number of products is not cost-effective.
4, high temperature oxidation coloring method: in a specific molten salt, dipped in stainless steel color plate to maintain a certain process parameters, the formation of a certain thickness of the oxide film on the workpiece, the performance of a variety of colors.
5. Gas phase decomposition and coloring method: complex and rarely used in industry.
