How the machine do the clean work?
1. Using the difference in the absorption coefficient of the laser energy of a certain wavelength between the substrate and the surface contaminants, the substrate material and the surface contaminants absorb energy and produce thermal expansion. When the expansion force of the dirt is greater than the adsorption force of the dirt on the substrate, the dirt will be separated from the object s surface
2. The laser can achieve a high concentration of energy in time and space, and the focused laser beam is at the focal point. High temperatures of thousands of degrees or even tens of thousands of degrees can be generated nearby, causing dirt to evaporate, gasify or decompose instantaneously.
3. Use high-frequency pulsed laser to irradiate the surface to be cleaned. The laser beam can generate ultrasonic waves on the solid surface to generate mechanical resonance to vibrate and break the dirt layer or condensate.
