Description
Technical Field
The invention belongs to a surface treatment technology, and particularly relates to an environment-friendly coloring process for a stainless steel wire mesh.
Background
Stainless steel has high strength and high corrosion resistance, and thus is widely used in bridge, machinery, electric appliance, chemical industry, vehicle and other fields. The stainless steel surface coloring treatment is to form a layer of film with special luster and certain wear resistance and corrosion resistance on the stainless steel surface. The coloring of the surface of the stainless steel wire mesh not only can endow the non-manufactured goods with rich color and luster, increase the variety of the products, but also can improve the corrosion resistance of the products.
The stainless steel surface coloring film has different structures, different roughness or different thicknesses, and different refractive indexes to light, thereby showing different colors.
Common staining methods for stainless steel surfaces include: organic coating, ion deposition, chemical coloration, electrochemical coloration, high-temperature oxidation, vacuum sputtering, and gas-phase pyrolysis. The organic matter coating method and the chemical coloring method have great pollution to the environment, the film layer obtained by the ion deposition method has weak binding force with a substrate, the electrochemical coloring method needs to be provided with a direct-current stabilized voltage power supply and carry out hardening treatment on the film layer, the high-temperature oxidation method has high energy consumption, the vacuum sputtering method has high investment cost, some methods need poor binding force, some methods have high requirements on the shape of a product, the gas-phase cracking coloring method is complex, and the method is less in industrial application.
The stainless steel wire mesh is more difficult to color due to the complex structure of the mesh.
