Definition of laser cleaning

The laser cleaning technology is the process of using the high pulse energy of the laser to irradiate on the surface of the workpiece, to make the dirty-stains, rust, coating and etc. evaporate or peel off instantly, to achieve the cleaning effect.

 

The principle of laser cleaning:

The pulse energy Laser cleaning process depends on the characteristics of the pulse energy beam generated by the laser. It based on the high-energy photo physical reaction caused by the interaction among the high-intensity laser beam, short-pulse laser and pollution layers. The physical principles can be summarized as follows:

  1. The laser beam should be absorbed by the contamination layer on the surface to be cleaned.
  2. The absorption of a large amount of laser energy forms a rapidly expanding plasma (a highly ionized unstable gas), which generates shock waves.
  3. The laser beam generates ultrasonic waves on the solid surface to generate mechanical resonance and break the dirt off.
  4. The pulse width of the laser must be short enough to avoid heat accumulation that would damage the base material.
  5. Experiments show that when there is oxide on the metal surface, plasma is generated on the metal surface.latest company news about Laser Cleaning Principle  0
