Laser cleaning The traditional cleaning industry has a variety of cleaning methods, mostly using chemical and mechanical methods for cleaning. Today, China's environmental protection regulations are becoming more stringent, and people's awareness of environmental protection and safety is increasing. The types of chemicals that can be used in industrial production cleaning will become less and less. How to find a cleaner, non-damaging cleaning method is a problem we have to consider. Laser cleaning has the characteristics of no grinding, non-contact, no heat effect and cleaning of objects suitable for various materials, and is considered to be the most reliable and effective solution. At the same time, laser cleaning can solve problems that cannot be solved by traditional cleaning methods.
For example, when subsurface-sized particles are adhered to the surface of the workpiece, the particles tend to stick very tightly. Conventional cleaning methods cannot remove it, and it is very effective to irradiate the surface of the workpiece with a nano laser for cleaning. Also, since the laser is non-contact cleaning of the workpiece, it is safe to clean the precision workpiece or its fine parts, and the accuracy can be ensured. Therefore, laser cleaning has unique advantages in the cleaning industry.
Why can the laser be used for cleaning? Why is there no damage to the object being cleaned? First understand the nature of the laser. Simply put, the laser is no different from the shadows (visible and invisible) that are around us, except that the laser uses the cavity to concentrate the light in the same direction, with simple wavelengths, coordination, etc. The performance is better, so theoretically all wavelengths of light can be used to form the laser, but in reality it is limited by the few media that can be excited, so the laser source that is stable and suitable for industrial production is quite limited. Probably used are Nd:YAG lasers, carbon dioxide lasers, and excimer lasers. Since Nd:YAG lasers can be more suitable for industrial applications through optical fiber transmission, they are also used in laser cleaning
