Dirty military uniforms can be washed, but if the guns, ammunition, weapons and equipment are dirty, can you always wash the faucet directly?
Today, in addition to traditional mechanical cleaning methods, chemical cleaning methods, and ultrasonic cleaning methods, there is an additional laser cleaning method. This "laser cosmetology" that uses a high-energy laser beam to irradiate the surface of an object and "remove" particles, dirt, rust, or attachments is a beautician who makes all kinds of equipment "rejuvenate."
The laser cleaning technology mainly uses the high energy, high frequency, and high power characteristics of the laser to drive a high-energy-density beam in a small area on the surface of the object to be cleaned, and uses the difference in laser absorption capability between the substrate material and the attachment to make the surface of the object " The filth deposit or coating instantly "evaporates" or peels off.
Compared with traditional cleaning methods, laser cleaning has many advantages such as non-contact, no grinding, no thermal effect, and wide applicability. It is considered to be the most reliable and effective “cleaner” and is currently used in weapons and equipment cleaning, cultural relic protection and the areas such as precision parts processing play an important role.
Any object that has been put on for a long time will inevitably be contaminated with dust, not to mention cultural relics that span over a thousand years. In order to remove the surface of the cultural relics such as smoke, rust, mold, insect spots, etc., artificial mechanical descaling and other methods will inevitably cause damage to the cultural relics.
In order to return the historical relics to “a true face”, the “Heritage Hospital” of the National Palace Museum in China had used MRJ laser cleaning techniques to “store life” for the collection of cultural relics. In fact, people have used laser cleaning to clean up the moss at the Leshan Giant Buddha in China long time ago.
Europe monuments such as the Amiens Cathedral in France and the Cologne Cathedral in Germany have also been revived after being laser-washed. The ancient palace has been replaced with new ones.
Even the "traces" of the years can be repaired by skill, the maintenance of weapons and equipment is obviously easy. The laser cleaning technology can remove the rust and contaminants on the equipment surface 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 melting layer can be formed on the metal surface of the equipment, which can further enhance the strength and corrosion resistance of the metal surface, and the “face-changing” equipment is also put on. An iron cloth shirt that is not afraid of erosion. After re-painting, aircraft that have been flying for a period of time can also completely remove the paint layer by laser cleaning. The metal surface is still “undamaged” and the service life of fighter aircraft is greatly improved.
The "18 martial arts" of laser cleaning is still more than that. Electronic equipment on the information battlefield must undergo the test of cruel environment. Electronic components will inevitably be contaminated with dust, affecting the efficiency of electronic equipment. Laser cleaning can make electronic equipment “back to life”. Tanks, aircrafts and even spacecraft and other types of machinery and equipment often need to clean the oil used for lubrication of parts.
The biggest advantage of laser cleaning over chemical methods is the “double care” of the part surface. Laser cleaning can also be used for the cleaning of pipelines in reactors of nuclear power plants. Equipment production molds can also be “washed” clean by laser. Even if it concerns the food that used for hunger on the battlefield, the production equipment needs to be regularly cleaned in the production process. Laser cleaning can also be used to “take a 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 out is easier to store and recycle. The "soft and invisible" light will not produce "secondary damage" such as mechanical action on the surface of the equipment, and the cleanliness is high. At the same time, the laser cleaning is highly efficient, uses less time with a low running cost. It can also be fully automated.
It can be foreseen that this "new generation" cleaning technology will certainly play an important role in the future maintenance of equipment.
