The most advanced laser cleaning system adopts pulse laser: the high-intensity laser acts on the surface of the object at the frequency of 4000KHz, and it’s absorbed by the pollutants on the surface, resulting in evaporation, gasification and other reactions.
At the same time, the absorption of large energy will form a rapidly expanding plasma (highly ionized unstable gas), which will produce shock wave and crush pollutants, and peel them from the substrate surface.
One of the difficulties of this technology is how to make full use of the characteristics and energy of the pulse laser, and let the laser travel to and from the contaminated layer at a very high frequency. While avoiding the heat accumulation and re-oxidation on the surface, it can also make the energy of a single point laser higher than that of the stripped contaminated layer.
The second difficulty is that the algorithm of the software must be accurate and efficient, controlling the point of action of the laser so that it can act on more areas in the same time.
Chihalo has fully independent technology and a number of patents, production and sales of the most advanced laser cleaning machine!
