15 cubic meters, 20 cubic meters of carbon dioxide price, carbon dioxide storage tank surface coloring treatment

Description :

　　Surface coloring treatment of carbon dioxide storage tank

　　Stainless steel coloring not only endows stainless steel products with various colors and increases their variety of colors, but also improves their wear resistance and corrosion resistance.

　　There are several methods for coloring stainless steel, including:

　　⑴ Chemical oxidation coloring method:

　　The color of a film formed by chemical oxidation in a specific solution can be achieved through methods such as dichromate, mixed sodium salt, sulfurization, acidic oxidation, and alkaline oxidation.

　　⑵ Electrochemical coloring method:

　　It is the color of a film formed by electrochemical oxidation in a specific solution.

　　Chemical method for ion deposition oxide coloring:

　　It is to place stainless steel workpieces in a vacuum coating machine for vacuum evaporation coating. For example, watch cases and straps coated with titanium gold are usually golden in color. This method is suitable for processing large quantities of products. Due to the large investment and high cost, it is not cost-effective to produce small quantities of products.

　　⑷ High temperature oxidation coloring method:

　　It is a process of immersing the workpiece in a specific molten salt to maintain the process parameters, forming a thick oxide film on the workpiece and presenting various colors.

　　Gas phase cracking coloring method:

　　More complex and less commonly used in industry. The choice of stainless steel surface treatment method should be based on the product structure, material, and different surface requirements, and the appropriate method should be selected for treatment.
