The application of laser cleaning mainly comes from the need for a non-toxic and non abrasive cleaning method in the market. This method can be used as an alternative to the previous chemical cleaning, manual cleaning and abrasive jet cleaning methods.
Laser Cleaning Applications
Surface polishing and derusting in steel manufacturing
1) When metals are exposed to moisture, they react with water to form ferrous oxide and rust. This rust reduces the quality of the metal and makes it unsuitable for a variety of applications.
2) On the other hand, due to the heat treatment process, an oxide layer will be formed on the metal surface, which will change the color of the metal surface, thus hindering the subsequent finishing operation.
Clean anode assembly
1) The presence of dirt and other pollutants will increase the resistance of the anode, resulting in more battery power consumption.
2) The existence of pollutants also shortens the service life of the anode by increasing the consumption rate of the anode in the smelting process.
Prepare for metal bonding
1) In order to improve process stability, surface adhesion and better welding quality, the surface of metal materials to be connected must be prepared before welding and other connection technologies are applied.
2) If the necessary cleaning treatment is not carried out on the surface of metal materials, the joints and joints are easy to deteriorate, aggravate wear and even catastrophic failure.
Prepare for brazing and welding
1) It helps to remove black and non-ferrous metals, lubricants and other contaminants from metal and aluminum surfaces in preparation for high-quality welding.
2) It also ensures smooth and non porous brazed welds.
Local coating removal
1) It can be used for almost all surface types, whether chemical anodic oxide layer, oxide layer or organic coating.
2) Laser cleaning can remove coatings and paints in automotive and other industries while maintaining the integrity of substrate materials.
Selective paint removal
The application of laser polishing, surface cleaning and coating removal is expanding rapidly. Depending on the application, the pulse frequency, energy and wavelength of the laser must be accurately selected to clean, polish and ablate the target material. At the same time, any form of damage to the base material must be prevented. At present, laser cleaning technology is mainly used to clean small parts. Of course, this technology is also likely to be suitable for cleaning large areas of surfaces and large equipment / structures. With the current progress in this field, these visions are expected to become a reality in the near future.
