The precision machinery industry often requires the removal of esters and mineral oils used for lubrication and corrosion resistance on parts, usually using chemical methods, and chemical cleaning often still leaves residues.
Laser de esterification can completely remove esters and mineral oils without damaging the surface of the parts. The following introduces the cleaning application of laser cleaning machines in precision instruments.
The removal of oil esters in mechanical parts processing can also be achieved through laser cleaning, and the removal of pollutants is completed by shock waves. The explosive vaporization of oxide thin layers on the surface of the parts forms shock waves, leading to the removal of pollutants rather than mechanical interactions.
Laser cleaning technology mainly utilizes the characteristics of high energy, high repetition rate, and high power of laser to project a high-energy density beam onto a small area of the surface of the object to be cleaned. By utilizing the difference in laser absorption ability between the substrate material and the attachment, the attachment or coating on the surface of the object that contains dirt and grime can instantly evaporate or peel off.
Laser cleaning does not require the use of any chemical agents, and the solid waste cleaned is easier to store and recycle.
The "soft and invisible" light will not cause secondary damage such as mechanical effects on the surface of equipment, and it has a high level of cleanliness. At the same time, laser cleaning has high efficiency, less time consumption, and low operating costs. Although purchasing a laser cleaning system requires a high initial investment, it can be used stably for a long time with low operating costs. More importantly, it can easily achieve automated operations.
The above is the precise de esterification cleaning application of laser cleaning machines in precision instruments. In the industrial application field, with the rapid development of lasers and the continuous deepening of research on laser cleaning mechanisms, surface quality monitoring and characterization methods are becoming increasingly complete and comprehensive. The surface quality of laser cleaning materials has been improved, and the cleaning accuracy and efficiency have also gradually increased.
