Laser cleaning technology has revolutionized the cleaning industry, thanks to its ability to offer superior cleaning results without harming the environment or the surface of the object being cleaned. By using nanosecond or picosecond pulsed lasers to irradiate the surface of the object, hand held laser cleaning effectively removes oil, rust, dust residue, coatings, oxide layers, and film layers from the surface, leaving it sparkling clean. In this article, we will discuss the various industries that have benefitted from laser cleaning technology.
Hand held laser cleaning is a non-contact cleaning method that is ideal for cleaning molds. This method is not only safe for the surface of the mold, but it can also ensure its precision. Hand held laser cleaning can effectively remove submicron dirt particles that cannot be removed by traditional cleaning methods, offering efficient and high-quality cleaning without any pollution.
Precision Instrument Industry
In the precision machinery industry, it is often necessary to remove esters and mineral oils used for lubrication and anti-corrosion on parts. Traditionally, chemical methods are used, but they often leave behind residues. Laser degreasing, on the other hand, can completely remove esters and mineral oil without damaging the surface of the parts. The laser causes the explosive vaporization of a thin layer of oxide on the surface of the part to form a shock wave that results in the removal of the dirt, instead of mechanical interaction.
Currently, all rails are cleaned using grinding wheels and abrasive belts before welding. However, this method damages the base material and results in serious residual stress. Moreover, a large amount of grinding wheel consumables are consumed every year, making it a costly process that causes serious dust pollution to the environment. Laser cleaning technology provides a high-quality and efficient green cleaning solution for the production of high-speed railway tracks, eliminating seamless rail holes, gray spots, and other welding defects, improving the stability and safety of the country’s high-speed railway operation.
The surface of an aircraft needs to be repainted after a certain period of time, but the original old paint needs to be completely removed before painting. Chemical immersion or wiping is the main paint removal method in the aviation field, but it produces a large amount of chemical subsidiary waste and cannot achieve partial maintenance and paint removal. Moreover, the process is heavy in workload and endangers health. Laser cleaning technology enables high-quality paint removal from aircraft skin surfaces and is easy to automate. This technology has already been applied to the maintenance of some high-end models abroad.
Traditionally, sandblasting is used for prenatal cleaning of ships, but it has caused serious dust pollution to the surrounding environment and has been gradually banned, resulting in reduced production or even shutdown of shipbuilding enterprises. Hand held laser cleaning provides a green and pollution-free cleaning solution for ship surface anti-corrosion spraying.
Laser cleaning technology is widely used in weapon maintenance. The laser cleaning system can remove rust and pollutants efficiently and quickly, and can select the cleaning part to realize the automation of cleaning. Using laser cleaning, not only is the cleanliness higher than the chemical cleaning process, but it also has almost no damage to the surface of the object.
Laser cleaning technology has proven to be a game-changer in various industries. Its superior cleaning ability, coupled with its environmental friendliness, makes it an attractive option for industries that are looking for a reliable, efficient, and green cleaning solution. With continued advancements in laser technology, it is expected that hand held laser cleaning will become more widely used in other industries in the future.
