Principles and methods of laser cleaning
Advantages of laser cleaning machines:
firstly,The laser is of high directivity, monochromaticity, high coherence and high brightness. Through the focus of the lens and the Q switch, the energy can concentrated into a small space and time range. In the laser cleaning process, here are some characteristics below:
1. The laser can achieve a high concentration of energy in time and space. The focused laser beam can generate thousands of degrees or even tens of thousands of degrees in the vicinity of the focal point, so that the dirt can instantly evaporate, gasify or decompose.
2. secondly,The divergence angle of the laser beam is small and the directivity is good. The laser beam condensed into spots of different diameters through the focusing system.
Under the condition of the same laser energy, controlling the laser beam spot of different diameters can adjust the energy density of the laser,
so that the dirt will be heated and expanded. When the expansion force of the dirt is greater than the adsorption force of the dirt to the substrate,
and then the dirt will be separated from the surface of the object.
Thirdly,The laser beam can generate ultrasonic waves on the solid surface to generate mechanical resonance. It can break the dirt off.
Laser cleaning technology uses the characteristics of the above-mentioned laser to achieve the purpose of cleaning.
