Common Sense of Colored Stainless Steel Sheet

Advantages of colored stainless steel sheet

The new material colored stainless steel sheet is made by chemical treatment on the stainless steel surface. The main products are color stainless steel sheet board and stainless steel decorative sheet. Colored stainless steel carries out technical and artistic processing on stainless steel sheet, making it to be stainless steel decorative sheet with a variety of colors on the surface. Its color is available for light golden, yellow, golden yellow, sapphire blue, illegal guns, color, brown, young color, zirconium gold, bronze, pink, champagne and a variety of decorative stainless steel sheet in other colors. Color stainless steel decorative sheet has the advantages of strong corrosion resistance, high mechanical properties; color surface is prolonged and does not fade, the color changes with the angle of light tone, etc. In addition, the colored surface layer of colored stainless steel decorative sheet is temperature resistant to 200℃ and its salt and spray corrosion resistance is better than ordinary stainless steel, the good wear resistance and scratch performance is equivalent to the performance of the foil layer coated with gold.

Introduction of color processing for stainless steel sheet

The manufacturing process of color stainless steel sheet is not simply coated a layer of color agents on the stainless steel surface, which can produce rich and vibrant colors, but it is achieve through very complex processes. At present, the method used is the acid bath oxidation coloring, generating the transparent layer of chromium oxide thin films on the stainless steel surface, which will produce different colors due to different film thickness when the light shines above. The color processing for stainless steel includes shading and the dura mater treatment two steps. The shading is carried out in the hot chrome sulfuric acid solution groove, when stainless steel immersed in, it will generate a layer of oxide film on the surface whose diameter is only a one percent-thick of the hair. With time goes by and the thickness increases, the color of the stainless steel surface will constantly change. When the oxide film thickness ranges from 0.2 micron to 0.45 m, the color of the stainless steel surface will show the blue, gold, red and green. By controlling the soaking time, you can get the desired color stainless steel coil. After subdural processing, the cathode, chromium oxide and other stable compounds can be generated. 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, making the overall performance of the material greatly improved.

Color stainless steel sheet is widely applied in many fields

The corrosion resistance and wear resistance for colored stainless steel sheet product surface is stronger than ordinary stainless steel, which can withstand more than 10 years of salt spray corrosion and discoloration for more than 30 years on UV irradiation. The main body integrates with the coloring layer, maintaining the basic structure and performance of the original stainless steel, which can process the conventional molding and stretch forming. The coloration surface is featured by bright color, soft, strong elegant finish and other advantages. Color stainless steel sheet is widely applied in many fields, which can be used in elevators, hardware and home appliances, kitchen appliances, cabinets, architectural decoration, advertising signs and daily necessities, etc. The value of the products is greatly improved, which has a significant market competitive advantage.
