Colored stainless steel is an environmentally friendly decorative material, free of methanol and other organic matter, no radiation, safety and fire protection, suitable for large-scale architectural decoration (car stations, railway stations, subway stations, airports, etc.), hotel and building business decoration, public facilities, new homes Decoration and so on.

As color stainless steel is getting closer to people's lives, daily maintenance and cleaning naturally becomes something that cannot be ignored. Here are some experiences to share with everyone:

1, the surface of dust and dirt with soap weak wash and warm water wash

2, trademarks, film with warm water and weak detergent to wash. The binder component is scrubbed with alcohol or organic solvents.

3. Contaminate the surface with grease, oil, and lubricating oil. Wipe it with a soft cloth and then wash it with a neutral detergent or ammonia solution or a special detergent.

4. If acid adheres, rinse immediately with water, dip with ammonia solution or neutral carbonated soda solution, and wash with neutral or warm water.

5, stainless steel surface has a rainbow pattern, is excessive use of detergent or oil caused by washing with warm water washable.

6, stainless steel surface dirt caused by rust, can be washed with 10% ** or grinding detergent, can also be washed with specialized washing drugs.

"Colored stainless steel processing methods and uses"

Stainless steel has been used more and more widely in recent years because of its uniqueness. We have seen some of the major cities in the world where a colorful building has been erected and towered into the sky. From morning to evening, these buildings can display the continuous changes of various colors such as gold, dark green, sky blue, and purple in stages under the sunlight, showing a beautiful and wonderful scenery. Originally, these buildings used a colored stainless steel surface with a colorless transparent oxide film as the outer wall and window frame decoration, because this layer of oxide film interferes with the sunlight at different angles of incidence, the building created the above-mentioned beautiful scenery.

Nowadays, the use of colorful stainless steel products on buildings abroad as a decoration has become all the rage. WiQ industrial design. China's color stainless steel not only has the unique luster and strength of metal, but also has a variety of colors and long-lasting colors. It not only maintains the physical, chemical and mechanical properties of the primary stainless steel, but also has stronger corrosion resistance than the primary stainless steel. Therefore, it has been widely used in fields such as building materials, chemicals, automobiles, electronics, and arts and crafts since its inception in the 1970s.

At present, color stainless steel has developed rapidly in foreign countries, and dozens of companies in more than 10 countries have been mass-produced. WiQ industrial design. The stainless steel coloring methods that have been used abroad include non-ferrous metal coloring, enamel coloring, organic coating coloring, and surface oxidation coloring. Among them, the low-temperature surface oxidation coloring method, the process is simple, the cost is low, the color stainless steel produced is beautiful and durable, it is the leader in various stainless steel coloring methods. WiQ industrial design. Before adopting low-temperature surface oxidation coloring, China must first polish the surface of stainless steel. The higher its smoothness, the more uniform the color when coloring and the brighter the color. After polishing, pickling is also performed to remove the naturally formed oxide film while avoiding corrosion of the surface.

In the process of coloring, controlling the reproducibility of the color by the coloring potential method is the key to the coloring process of low-temperature surface oxidation treatment. The colored film formed on the surface of the stainless steel after coloring is an oxide film, and this film is actually colorless, but only because of its interference with light, the color is formed. The thickness of the film varies depending on the thickness of the film, and the thickness of the oxide film obtained by the difference in the coloring potential is also different. In other words, the thickness of the oxide film can be controlled at will, or the oxide film can be dissipated, so that the colored stainless steel can be restored to the original stainless steel. WiQ industrial design. In China, the use of pulsed lasers and computer-aided design has led to the development of successful new manufacturing techniques for colored stainless steel. The method is to immerse the stainless steel plate in the ** solution first and then irradiate it with a pulsed laser to control the length of the irradiation time. The surface of the steel plate will show seven colors of blue, green and gold, and the required cost is only other colors. One-seventh of the craft. WiQ industrial design. The new technology in China is to impregnate chromium-containing 17% stainless steel plates with chromium-containing 18% stainless steel plates containing 8% nickel in 5% solution and then pulsed with an energy density of 0.8 Joules per square meter. It was found that the amount of chromium in the part of the stainless steel plate not irradiated by laser light was reduced by 10%; and the part of the chromium irradiated by the laser light increased with the increase of the irradiation time, and the highest chromium content was up to 30%. WiQ industrial design. Under the pulsed laser irradiation in China, the color of the oxide film formed on the surface of the stainless steel plate changes as the chromium content increases. WiQ industrial design. In China, the commonly used primary stainless steel, austenitic stainless steel is the most suitable coloring material, and can obtain a satisfactory color appearance. Ferritic stainless steels are not as bright as the former due to the possibility of increased corrosion in the coloring solution. The low-chromium high-carbon martensitic stainless steel, due to its poorer corrosion resistance, can only get dark colors or black surfaces. It has been reported that austenitic stainless steels are colored by a low-temperature surface oxidation coloring method and exposed to the industrial atmosphere for 6 years, exposed for a year and a half in a marine atmosphere, soaked in boiling water for 28 days, or heated to about 300°C. There is no change in the color luster. In addition, it can withstand general molding, drawing and bending, and work hardening. WiQ industrial design. In China, colored stainless steel can be used in many other fields in addition to the exterior wall and window frame decoration. For example, a black solar panel can be used to make a solar collector board, and the choice of heat absorption rate can reach 91% to 93%. In the arts and crafts community, color stainless steel is combined with printing technology, which can be used in combination with etching and grinding and dot technology to produce three-dimensional relief murals and hanging screens that will never fade. In addition, the use of colored stainless steel for the manufacture of home appliances, cooking utensils, kitchen equipment, and bathroom appliances will be deeply loved by consumers.
