Five kinds of stainless steel wall panels of stainless steel wall panels coloring process color methods as follows: 1, the chemical oxidation coloring method; 2, electrochemical oxidation coloring method; 3, ion deposition oxide coloring; 4, high temperature oxidation coloring; 5, gas-phase pyrolysis coloring. A brief overview of various methods as follows: 1, the chemical oxidation coloring method is a specific solution to form a color film by chemical oxidation with dichromate method, mixed sodium method, curing method, acid oxidation and alkaline oxidation . Generally, "Yin Branch Law" more (INCO) use, but a number of products in order to ensure consistent color, it must be controlled by the reference electrode. 2, electrochemical coloring method is the specific solution, the color of the film is formed by electrochemical oxidation. 3, ion deposition oxide coloring chemical is placed in a stainless steel vacuum coating machine the workpiece vacuum evaporation plating. For example: titanium gold watch case, watch band, usually gold. This method is suitable for high-volume processing. Because investment, high cost, low-volume products uneconomical. 4, the high temperature oxidation coloring molten salt in particular, showing a variety of different colors to keep the workpiece is immersed in a certain process parameters, so that the workpiece to form a certain thickness of the oxide film, and. 5, gas vapor cracking cracking coloring coloring is more complex, rarely used in industry.
