Rusting of metal is a chemical reaction that is essentially an oxidizing reaction of the metal. The most common form of rusting is the oxidation of iron products when exposed to air and oxygen for a long period of time, or when they are attacked by oxygen in water and become oxidized.
Some metals produce a dense oxide film after rusting to prevent further oxidation of the metal, such as aluminum oxide. Some metals produce a loose oxide film after rusting, which accelerates the oxidation of the metal, e.g. rust. All metals in different environments will produce oxidation or other chemical reactions, strictly speaking, there is no metal that does not rust.
The traditional way of rust removal will cause damage to the surface of the workpiece, cleaning is not clean, causing environmental pollution and other issues, laser cleaning is a non-abrasive, non-contact new environmentally friendly cleaning methods, while the traditional cleaning methods can not solve the problem, is considered the most reliable and effective solution. The principle of laser cleaning is to use high-frequency high-energy laser pulse to irradiate the surface of the workpiece, the coating layer can instantly absorb the focused laser energy, so that the surface of the oil, rust spots or coatings occur instantly to be stripped off, high-speed and effective removal of surface adhesions or surface coatings of the cleaning method, and the action of the laser pulse of a very short period of time in the appropriate parameters will not harm the metal substrate.
Laser descaling is more advantageous than traditional descaling methods, both technically and socially and economically. For example, technically, laser descaling equipment can precisely control the area of descaling; remove only surface contaminants/adherents; and can be hand-held or automated. In the social and economic, laser descaling equipment does not use chemicals to clean, no pollution of the environment, there is no great noise; laser descaling equipment is simple to operate, the personnel can be very quickly on the operation, to solve the problem of labor difficulties. Laser descaling equipment descaling efficiency, can reduce a certain amount of manpower.
