Laser Cleaning Technology - Beautician Of Weapons And Equipment

Mar 28, 2019

Nowadays, in addition to the traditional mechanical cleaning method, chemical cleaning method and ultrasonic cleaning method, a laser cleaning method has been added. This kind of "laser cosmetology" that uses high-energy laser beams to illuminate the surface of objects and "remove" particles, dirt, rust or attachments is a beautician who makes all kinds of equipment "rejuvenate".

The laser cleaning technology mainly utilizes the characteristics of high energy, high frequency and high power of laser, and the high energy density beam is applied to a small area on the surface of the object to be cleaned, and the difference in laser absorption capacity between the substrate material and the attached object is used to make the surface of the object " The deposit or coating of the smudges "evaporates" or peels off instantaneously. Compared with the traditional cleaning method, laser cleaning has many advantages such as non-contact, no grinding, no heat effect and wide applicability. It is considered to be the most reliable and effective "cleaner". It has been cleaned up in weapons and equipment and protected by cultural relics. The field of precision parts processing plays an important role.

Any item that has been left for a long time will inevitably be contaminated with dust, not to mention the cultural relics that span the millennium. In order to remove the "smoke" such as smoke, dust, mould, and plaque on the surface of cultural relics, artificial mechanical descaling and other methods will inevitably cause damage to cultural relics. In order to restore the historical relics, the “Relics Hospital” of the Palace Museum used laser cleaning technology to “enhance life” for the collection of cultural relics. In fact, people have long used laser cleaning to clean up the moss for the Leshan Giant Buddha. Foreign monuments such as the Amiens Cathedral in France and the Cologne Cathedral in Germany are also revived after laser cleaning. The ancient palace is instantly renewed.

Even the "marks" of the years can be repaired by skill, not to mention the maintenance of weapons and equipment. Laser cleaning technology can remove the rust and pollutants on the surface of the equipment quickly and efficiently, which is equivalent to a "deep cleaning" of the equipment. At the same time, by setting different parameters, a dense oxide protective film or metal molten layer is formed on the surface of the equipment metal, which can further enhance the strength and corrosion resistance of the metal surface, and the equipment of "changing the face" is also put on. An "iron cloth shirt" that is not afraid of erosion. When the aircraft flying over a period of time is repainted, the surface paint layer can be completely removed by laser cleaning, and the metal surface is still “unscathed”, thereby greatly improving the service life of the fighter.

The "eighteen martial arts" of laser cleaning is not only this. The electronic equipment on the information battlefield must undergo the test of the cruel environment. The electronic components will inevitably be contaminated with dust, which will affect the working efficiency of the electronic equipment. The laser cleaning can make the electronic equipment "return to life". Tanks, airplanes, and even spacecraft, as well as various types of mechanical equipment, often need to clean the oil used to lubricate the parts.

The biggest advantage of laser cleaning over chemical methods is the “care” of the surface of the part. Laser cleaning can also be used for the cleaning of pipelines in nuclear power plant reactors. Equipment production moulds can also be "washed" clean with the aid of lasers. Even if it is related to the field food used to fill the hunger on the battlefield, the production equipment needs to be cleaned regularly during the production process. Laser cleaning can also be used to “take the top handle”.

More importantly, laser cleaning is still a “green” cleaning method. It does not require the use of any chemicals, and the solid waste that is washed is easier to store and recycle. The “soft and invisible” light does not cause “secondary damage” such as mechanical action on the surface of the equipment, and the cleanliness is high. At the same time, laser cleaning is highly efficient, uses less, and costs less, and enables fully automated operation.

It is foreseeable that this "new generation" cleaning technology will play an important role in the future maintenance of equipment.
