Industrial laser cleaning service
1. Technical background introduction
Traditional cleaning methods include mechanical cleaning methods, chemical cleaning methods, and ultrasonic cleaning methods, and their applications in environmental protection and high precision requirements are greatly limited. In the 1980s, it was discovered that focusing high-energy laser beams irradiated the contaminated parts of some articles, causing the irradiated substances to vibrate, melt, evaporate, and burn a series of complex physical and chemical processes, which could eventually make the pollutants It is detached from the surface of the article to achieve the removal of surface contaminants. This is laser cleaning. It gradually replaces the traditional cleaning process in many fields with its many advantages, showing a broad prospect for development.
2.Laser cleaning working mechanism
Laser has the characteristics of high intensity, high energy density, strong focus, and good directivity. Laser cleaning technology uses three effects of laser pulse vibration, particle thermal expansion, molecular photodecomposition or phase change to overcome pollution The binding force between the substrate and the surface of the substrate enables the dirt to escape from the surface and achieves the purpose of cleaning.
3. Advantages of laser cleaning technology
Since laser cleaning does not use any chemical solvents or other consumables, it is environmentally friendly, safe to operate, and has many advantages:
1. Green and environmentally friendly, without using any chemicals and cleaning fluids;
2. The cleaning waste is mainly solid powder with small volume and easy to collect and recycle;
3. The cleaning waste smoke is easy to absorb and handle, low noise, and no harm to human health;
4. Non-contact cleaning, no residual medium, no secondary pollution;
5. It can realize selective cleaning without damaging the substrate;
6. No working medium consumption, only electricity costs, low use and maintenance costs;
7. Easy to realize automation and reduce labor intensity;
8. Suitable for hard-to-reach areas or surfaces, suitable for dangerous or dangerous environments.
