6 advantages of laser cleaning machine

Date:2019-08-31 15:58 Write:admin Click:

Laser cleaning techniques are often used in the treatment of industrial production, ancient artifacts and art protection, and even dental diseases. In the process of electroplating, phosphating, spraying, welding, packaging and integrated circuit assembly of industrial products, it is sometimes necessary to remove grease, dust, embrittlement and residual solvents, binders and the like on the surface of the product to ensure quality. However, due to environmental pollution and poor protection, industrial products, cultural relics and many precious artworks are gradually rusted and defaced, and some have been completely destroyed. It is necessary to take appropriate measures to remove the dirt and rust on the surface of cultural relics. Restore its old appearance.
 
Conventional cleaning techniques mainly use mechanical and chemical methods, chemical cleaning methods, and ultrasonic cleaning methods. However, these methods all have some shortcomings, mechanical methods can not meet the high cleanliness cleaning requirements; chemical cleaning methods are easy to cause environmental pollution; ultrasonic cleaning method, although the cleaning effect is good, but the cleaning of sub-micron particles can not do anything, the size of the cleaning tank Limits the scope and complexity of the parts being cleaned. These shortcomings limit the development of traditional cleaning techniques.
Mechanism of laser cleaning machine
The mechanism of laser cleaning is mainly based on the absorption of laser energy by the surface pollutants of the object, or vaporization and volatilization, or instantaneous thermal expansion to overcome the surface adsorption force on the particles, so as to get rid of the surface of the object, thereby achieving the purpose of cleaning.
It is roughly summarized as:
1. Laser vaporization decomposition; 
2. Laser peeling;
3. Thermal expansion of dirt particles;
4. Four aspects of substrate surface vibration and particle vibration
Characteristics and classification of laser cleaning technology
1. Compared with the traditional cleaning process, the laser cleaning technology has the following characteristics:
(1) It is a “dry” cleaning that does not require cleaning fluids or other chemical solutions and is much cleaner than chemical cleaning processes;
(2) The range of soil removal and the range of applicable substrates are very broad;
(3) By regulating the laser process parameters, it is possible to effectively remove the dirt on the basis of not damaging the surface of the substrate, so that the surface is as old as new;
(4) Laser cleaning can be easily automated;
(5) The laser decontamination equipment can be used for a long time, and the running cost is low;
(6) Laser cleaning technology is a “green” cleaning process. The waste material is solid powder, small in size, easy to store, and basically does not pollute the environment.
