Laser Cleaner-Superwave Laser Machine

Superwave Laser Technology Co.,Ltd | Updated: Dec 04, 2017


Principle and application of laser cleaning technology


In recent years, along with the people environmental protection consciousness enhancement, to the development of worldwide QingXiYe has brought the huge challenge, a variety of beneficial to environmental protection cleaning technology arises at the historic moment, laser cleaning technology is one of them. Laser cleaning technology refers to the use of high energy laser beam irradiation surface, the surface dirt and rusty spot or coating momentarily evaporation or splitting, high-speed effectively remove attachments to or surface coatings, clean the surface of the object so as to achieve a clean process. It is based on the effects of the interaction between laser and material, a new technology with the traditional mechanical cleaning, chemical cleaning and ultrasonic cleaning method (wet cleaning process), it doesn't need any ozone-depleting CFC type organic solvent, no pollution, no noise, harmless to the human body and environment, is a kind of "green" cleaning technology. Laser cleaning has obvious advantages compared with traditional cleaning methods such as mechanical abrasion cleaning, chemical corrosion cleaning, liquid solid strength shock cleaning and high frequency ultrasonic cleaning. It is efficient, fast and cost low, the thermal load and mechanical load of the substrate are small, and the cleaning is non-damage. Waste can be recycled without environmental pollution; Safe and reliable, do not harm operators health; The coating of different thickness and different components can be removed. The cleaning process is easy to realize automatic control and realize remote control cleaning.


The principle and method of laser cleaning


Laser is characterized by high directional, monochromatic, high coherence and high brightness. Through the lens focus and Q switch, energy can be concentrated into a small space and time range. In the laser cleaning treatment, the following characteristics are mainly used:

1, the laser energy can be highly concentrated in time and space, the focused laser beam in the vicinity of focus can produce a few red even tens of thousands of degrees high temperatures, dirt instantaneous evaporation, gasification or decomposition.

2. The divergence Angle of the laser beam is small and good directional, and the laser beam can be assembled into different diameter spots by the condenser system. In the same condition of laser energy, the laser beam spots of different diameters are controlled.

3. You can adjust the energy density of the laser and expand the dirt. When the swelling force of the dirt is greater than the adsorption capacity of the soil, the dirt will disengage from the surface of the object.
