Laser cleaning technology is the emerging application of a workpiece surface cleaning technology in the past decade, it is its own advantages and irreplaceability in many areas is gradually replacing the traditional cleaning process.
Traditional cleaning methods, including mechanical cleaning, chemical cleaning and ultrasonic cleaning method, mechanical cleaning method, that is, the use of scraping, rubbing, brushing, sandblasting and other mechanical means of removing surface contaminants; wet chemical cleaning method is the use of organic cleaning agents, through spraying, drenching, soaking or high-frequency vibration and other measures to remove the surface adhesion; ultrasonic cleaning method is the parts being processed into the detergent, the use of ultrasonic vibration effect to remove the Dirt. At present, these three cleaning methods in China's cleaning market is still dominant, but will varying degrees of pollutants, in environmental protection and high-precision requirements under the application of its great limitations.
Laser cleaning technology refers to the use of high-energy high-frequency laser beam irradiation of the surface of the workpiece, so that the surface of the dirt, rust spots or coatings occur instantly be stripped, high-speed and effective removal of the cleaning object surface attachments or surface coatings, so as to achieve a clean laser process. Lasers are characterized by high directionality, monochromaticity, high coherence and high brightness. Through the focusing and Q-switching of the lens, the energy can be concentrated into a small spatial and temporal range.
Laser cleaning advantages:
1,Environmental advantages
Laser cleaning is a "green" cleaning method, without the use of any chemicals and cleaning fluids, cleaning down the waste is basically a solid powder, small size, easy to store, recyclable, no photochemical reaction, will not produce pollution. Can easily solve the environmental pollution problems caused by chemical cleaning. Often an extractor fan can solve the problem of waste generated by cleaning.
2, the effect of the advantages
Traditional cleaning methods are often contact cleaning, cleaning the surface of the object has a mechanical force, damage to the surface of the object or cleaning medium attached to the surface of the object to be cleaned, can not be removed, resulting in secondary pollution, laser cleaning of non-abrasive and non-contact, non-thermal effect will not damage the substrate, so that these problems are solved.
3,Control advantages
Laser can be transmitted through the fiber optic, and robots and robots to match, convenient to achieve long-distance operation, can clean the traditional method is not easy to reach the parts, which in some dangerous places to use can ensure the safety of personnel.
4, convenient advantage
Laser cleaning can remove various types of pollutants on the surface of various materials to achieve the cleanliness that conventional cleaning cannot achieve. And also can not damage the surface of the material in the case of selective cleaning of the material surface pollutants.
5, cost advantage
Laser cleaning speed, high efficiency, saving time; buy laser cleaning system, although the initial one-time investment is higher, but the cleaning system can be used for long-term stability, low operating costs, and more importantly, can be convenient to realize the automation operation.
