What is a laser cleaner?
Laser cleaning technology refers to the use of high-energy laser beams to irradiate the surface of the workpiece, so that the dirt, particles, rust spots or coatings, and other attachments on the surface evaporate or peel off instantaneously, so as to achieve a cleaning and purification process.
4 major features of laser cleaning machine:
Compared with ordinary chemical cleaning methods and mechanical cleaning methods, laser cleaning has the following characteristics:
It is a complete “dry cleaning process, no cleaning liquid or other chemical solutions are required, it is a “green” cleaning process, and the cleanliness is much higher than that of chemical cleaning processes;
- It is a complete “dry cleaning process, no cleaning liquid or other chemical solutions are required, it is a “green” cleaning process, and the cleanliness is much higher than that of chemical cleaning processes;
- The scope of cleaning is very wide. From large lumps of dirt (such as fingerprints, rust spots, oil stains, paint) to small fine particles (such as metal ultrafine particles, dust) can be cleaned by this method;
- Laser cleaning is suitable for almost all solid substrates, and in many cases can only remove dirt without damaging the substrate;
- Laser cleaning can easily realize automatic operation, and can also use optical fiber to introduce laser into the contaminated area. Operators only need to remotely operate remotely, which is very safe and convenient. This is important for some special applications, such as the rust removal of nuclear reactor condenser tubes. Meaning.
The type, power, and wavelength of the laser used for laser cleaning should be different depending on the composition and form of the material to be cleaned. The current typical equipment is mainly YAG laser and excimer laser. It is worth mentioning that the laser rust removal process is used on the steel surface. By selecting appropriate process parameters, the surface of the substrate can be micromelted while removing rust, forming a uniform and dense corrosion-resistant layer, which can remove rust and prevent corrosion. complete in one step. The laser cleaning process has been initially applied in the industry.
