As a new generation of high-tech products for industrial surface cleaning, laser cleaning plays a significant role in rust removal. Rusting of metals is inevitable. Rusting is a chemical reaction, which is essentially an oxidizing reaction of metals. The most common rust phenomenon is the long-term exposure of iron products in the air and oxygen oxidation reaction, or by the oxygen in the water to erode the element into oxides, but rust after re-use, you need to clean the metal surface rust.
The principle of laser cleaning is the use of high-frequency high-energy laser pulse irradiation of the surface of the workpiece, the coating layer can be instantly absorbed by the focused laser energy, so that the surface of the oil, rust spots or coatings occur instantly to be peeled off, high-speed and effective removal of surface adhesions or surface coating cleaning method, and the role of a very short time of the laser pulse, in the appropriate parameters will not harm the metal substrate. Laser cleaning has the advantages that traditional cleaning does not have, and is gradually replacing traditional cleaning.
Laser cleaning advantages of rust removal:
1, green cleaning: do not use any chemicals, cleaning waste for the solid harmless powder, can completely solve the problem of environmental pollution caused by chemical cleaning.
2, non-invasive cleaning: laser cleaning of non-abrasive and non-contact, non-thermal effect, will not be cleaned objects to produce mechanical force, will not damage the surface of the object, will not destroy the substrate, and will not produce secondary pollution.
3, low-cost cleaning: laser cleaning can be used for long-term stability, low operating costs, fast speed, high efficiency, time saving, and will soon be able to get a return on investment, in the long run, the cost is lower than the traditional cleaning methods.
4, precision and accurate cleaning: laser cleaning can remove various types of pollutants on the surface of various materials, to achieve the cleanliness of conventional cleaning can not be achieved. And also can not damage the surface of the material in the case of selective cleaning of the material surface contaminants.
5, automated cleaning: laser can be transmitted through the fiber optic transmission, and robots with the realization of long-distance operation, can clean the traditional methods are not easy to reach the complex parts of the structure, such characteristics also make in some dangerous places in the operator's safety is more secure. It can be matched with automation equipment to realize automated cleaning.
