Stainless steel decorative plate is a new type of environmental protection material, its manufacturing process is not in the surface of the stainless steel sandblasting plate simply coated with a layer of colorant, can produce colorful colors, and through very complex process to achieve. At present, the method used is mainly acid bath oxidation coloring method, so that the surface of the stainless steel decorative plate to produce a layer of transparent chromium oxide film, after the light above, will produce different colors because of the film thickness.
The whole process of color processing of stainless steel decorative plate includes two steps: color processing and dural processing. The coloring process is carried out in the hot chromic sulfuric acid solution tank, stainless steel decorative plate immersion, will produce a layer on the surface only a hair diameter 1/100th of the thickness of the oxide film.
With the extension of time and the increase of oxide film thickness, the color of stainless steel decorative plate surface is also changing. When the oxide film thickness increased from 0.2 micron to 0.45 meters, the color of the stainless steel decorative plate surface will appear blue, gold, red, green. The stainless steel decorative plate can be obtained by controlling the soaking time.
After dural treatment, stable compounds such as chromium trioxide and chromium hydroxide can be generated on the cathode. It not only fills the tiny pores in the oxide film, but also improves the wear resistance, corrosion resistance and heat resistance of the oxide film, so that the overall performance of the material is greatly improved.
Stainless steel decorative plate surface corrosion resistance, wear resistance is stronger than ordinary stainless steel, can resist more than 10 years of salt spray corrosion and more than 30 years of ultraviolet light does not change color. The main body is integrated with the coloring layer to maintain the basic structure and performance of the original plate. Stainless steel decorative plate coloring surface has the advantages of gorgeous color, bright color, gorgeous color, downy, elegant, strong finish and so on.
Decorated with it all show the quality of your yong, stainless steel decorative boards also have strong corrosion resistance, high mechanical properties, surface color is not faded, colour and lustre with different illumination Angle can produce tonal change wait for a characteristic, stainless steel decorative sheet when bending 90 ℃, the color layer will not damage, can be used as a room wall, ceiling, car plate, trunk board, building decoration, signs, such as decoration, color stainless steel plate are generally used in adornment metope.
