Stainless Steel sandblasting plate is a new type of environmental protection material. The manufacturing process of stainless steel sandblasting plate is not simply coated with a layer of coloring agent on the surface of the stainless steel sandblasting plate, can produce colorful colors, but through a very complex process to achieve. At present, the main method is acid bath oxidation coloring, so that the surface of stainless steel sandblasting plate to produce a layer of transparent and chrome oxide film, light irradiation above, because of film thickness and produce different colors. The whole process of color processing of stainless steel sandblasting plate includes two steps: 1. The coloring process is carried out in a hot sulfuric acid bath. When the stainless steel sandblasted plate is immersed, a layer of oxide film only 1/100th of the diameter of a single hair is formed on the surface. With the extension of time and the increase of oxide film thickness, the color of the surface of the stainless steel sandblasting plate is changing constantly. When the oxide film thickness increases from 0.2 Micron to 0.45 meter, the color of the surface of the stainless steel sandblasted plate will appear blue, gold, red and green in turn. By controlling the immersion time, people can get the required stainless steel sandblasting plate. 2. After being treated with Dura, stable compounds such as dichromium trioxide and chromium hydroxide can be formed on the cathode. Not only the tiny pores in the oxide film are filled, but also the wear resistance, corrosion resistance and heat resistance of the oxide film are improved. Stainless Steel sandblasted surface corrosion resistance, wear resistance than ordinary stainless steel, can resist more than 10 years of salt fog corrosion and more than 30 years of UV irradiating color. The main body is integrated with the coloring layer, which maintains the basic structure and performance of the original stainless steel sandblasting plate, and can be processed by conventional moulding and drawing. The coloring surface of the stainless steel sandblasting board has the advantages of beautiful color, bright color, bright tone, soft color, elegant and strong finish.
