The world's first laser was developed in 1960 by American scientist Professor Theodore Harold Maiman using ruby, which opened the door for lasers to benefit mankind. The next time, lasers used in various fields were born one after another. The promotion of laser technology has enabled the rapid development of science and technology in the fields of medical treatment, equipment manufacturing, precision measurement, and remanufacturing engineering, and accelerated the pace of social progress.
The application of lasers in the cleaning field has achieved important results. Compared with traditional cleaning methods, laser cleaning such as mechanical friction, chemical corrosion and high-frequency ultrasonic can realize fully automatic operation. It has high work efficiency, low cost, no pollution to the environment, no damage to the substrate, and a wide range of materials. The advantages are completely in line with the green and environmentally friendly processing concept, and it is the most reliable and effective cleaning method at present.
Laser cleaning is to decontaminate by destroying the bonding force between the pollutants and the substrate or by directly vaporizing the pollutants, reducing the bonding strength of the pollutants and the substrate, and then cleaning the surface of the workpiece.
The entire laser cleaning process is roughly divided into four stages, namely laser gasification decomposition, laser stripping, thermal expansion of pollutant particles, substrate surface vibration, and pollutant detachment. It can achieve the best cleaning effect without damaging the surface of the substrate.
Chinese scholars Wang Manman and others have studied the differences between laser cleaning and traditional cleaning methods, independently developed a hand-held laser cleaning system, applied Ezcad software, and found that the hand-held laser cleaning system is more convenient to use and is not restricted by the working environment. , For some relatively large workpieces, it is more convenient to remove rust than the desktop, and the application field is wider.
Experiments show that the rust and residual paint in the parts scanned by the laser irradiation is removed, the metallic luster of the matrix material is exposed, and the matrix structure is uniform and free of damage; the surface temperature of the material hardly changes.
In the maintenance and manufacture of military equipment, laser cleaning can improve the efficiency of equipment maintenance, reduce the oxidation of the surface of weapons and ammunition, and provide a strong guarantee for military equipment and military combat effectiveness.
After laser cleaning, the welding quality can be effectively improved, and the welding seam quality is first-class.
Laser cleaning technology can also save the production cost of enterprises and improve their production efficiency of enterprises.
Some scholars have applied femtosecond lasers to the field of cleaning and preservation of historical documents and documents, and have the advantages of high cleaning efficiency, small discoloration effect, and no damage to fibers.
Laser cleaning can not only effectively remove rust and dirt, but also generate a protective layer to prevent the substrate from rusting again and improve its corrosion resistance. At present, laser cleaning technology has been applied to various fields such as military industry, industrial production, microelectronics, cultural relics protection, and medical treatment.
