Beijing Jinli Hengwang Company answers you the practice of black stainless steel door frame cladding. Black stainless steel door frame is also called black stainless steel door cover, black stainless steel door frame cladding is generally made of black stainless steel. The black stainless steel is made of ordinary stainless steel through the titanium plating coloring process to the silver stainless steel plated with a layer of black, and then through the shearing, grooving, bending and processing.
Black stainless steel, also called black titanium stainless steel and black mirror steel, is one of the colors that are becoming more and more popular nowadays. For example, the latest Apple cell phone is with black mirror appearance. Black titanium stainless steel plate material 201, 304, 316, etc., the conventional size of 1220mm * 2400mm, 1000mm * 2000mm, 860mm * 610mm, 1220mm * 3050mm, etc., the thickness of 0.28mm ~ 5mm. black titanium stainless steel plate can be vacuum-plated water-plated, water-plated color than the vacuum-plated color is more vivid, the disadvantage is that the 304 material plated out blue. 304 material plated out of blue.
Black titanium stainless steel plate is a new type of material. Black titanium stainless steel plate manufacturing process is not in the stainless steel surface simply coated with a layer of coloring agent, can produce colorful colors, but through a 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 to generate a layer of transparent chromium oxide film, after the light shines on it, will be due to the thickness of the film is different and produce different colors. The whole process of color processing of stainless steel plate includes two steps of coloring treatment and hard film treatment. Color treatment is carried out in the hot chromic sulfuric acid solution tank, stainless steel immersed in the surface will generate a layer of only a hairline diameter of one percent thick oxide film. With the extension of time and the increase of the thickness of the oxide film, the color of the stainless steel surface is constantly changing. When the thickness of the oxide film from 0.2 microns increased to 0.45 m, the color of the stainless steel surface will be presented in blue, gold, red, green. People can get the desired black titanium stainless steel plate by controlling the impregnation time. Then after the hard film treatment, it can generate stable compounds such as chromium trioxide and chromium hydroxide on the cathode. Both fill the tiny pores in the oxide film, but also improve the wear resistance, corrosion resistance and heat resistance of the oxide film, so that the overall performance of the material is greatly improved. Black titanium stainless steel plate surface corrosion resistance, abrasion resistance than ordinary stainless steel, can withstand more than 10 years of salt spray corrosion and more than 30 years of ultraviolet irradiation without discoloration. The main body and coloring layer integration, maintain the basic structure and basic performance of the original stainless steel plate, can be conventional molding and stretch molding process. Black titanium stainless steel door cover coloring surface has the advantages of color mottled, bright color, color tone, soft, elegant, strong finish. The new material black titanium stainless steel door cover has a wide range of applications, can be used for elevators, hardware appliances, kitchen and bathroom appliances, cabinets, building decoration, advertising signs, daily necessities, etc., can greatly improve the added value of the product, with obvious competitive advantage in the market.
