What are the Methods of Laser Cleaning?
Laser cleaning is a method that does not require any chemicals or cleaning fluids. Basically, the residues are all solid powders, small in size, and easy to store. Therefore, it can solve the problem of environmental pollution caused by chemical cleaning. Below, MAMTECHNIC will introduce the use of laser cleaning machines. There are four laser cleaning methods common to see in daily life:
LASER CLEANING
- The pollution layer absorbs the beam emitted by the laser.
- The Energy forms a rapidly expanding plasma (highly ionized gas). Afterward, this will produce a shock wave.
- The shock wave breaks the contaminants into pieces and knocks them out.
LASER+LIQUID FILM CLEANING
Firstly, deposit a layer of liquid film on the surface of the substrate, and then use laser radiation to decontaminate. When the laser is irradiated on the liquid film, the liquid film is heated rapidly to produce explosive vaporization. The explosive shock wave loosens the dirt on the surface of the substrate. Then, these pollutants fly away from the surface of the processed object with the shock wave to achieve decontamination.
LASER + INERT GAS CLEANING
While the laser is irradiating, the operator uses an inert gas on the surface of the substrate. When stripped, the gas can immediately blown off the contaminants. Thus, This method can avoid re-contamination and oxidation of the surface.
LASER + CHEMICAL CLEANING
After laser irradiation, the operator uses a non-corrosive chemical method to clean the loose dirt. At present, people only use this method in cleaning stone cultural relics.
CONCLUSION
Laser cleaning technology is a new method developed rapidly in the past ten years. It is gradually replacing traditional surface cleaning due to its many advantages. And it can adapt to the cleaning of various surfaces. Moreover, it has very little pollution to the environment and hardly damages the substrate. There are mainly four kinds of laser cleaning methods mentioned above. You can choose the appropriate cleaning method according to the materials.
In recent years, the laser equipment industry has developed rapidly. MAMTECHNIC knows that only by continuously improving product quality can we meet customer requirements. Therefore, we will provide our customers with high-quality services so that every customer can feel our sincerity.
