As a "green" cleaning process, laser cleaning will have good application prospects in the maintenance of military equipment.
The analysis and experimental results show that complete cleaning of equipment mold can be achieved without damage to the substrate if the laser parameters are selected appropriately.
The mechanism of laser cleaning mold is as follows: a specific wavelength of high-energy beam of light is absorbed by the corrosion layer, paint layer, and pollution layer to form a rapidly expanding plasma (highly ionized unstable gas), and at the same time, a shock wave is generated. The shock wave causes the contaminants to become fragments and be removed. The laser pulse with a short action time will not harm the metal substrate under the appropriate parameters.
What are the advantages of traditional cleaning methods? Compared with chemical cleaning, it does not require chemical agents and does not pollute the environment; compared with mechanical cleaning, it does not touch parts, does not generate stress, and does not affect the performance of parts; compared with ultrasonic cleaning, laser cleaning can be carried out with a manipulator, and the operation is more flexible and efficient; and the power of the laser cleaning machine is only a few kilowatts, only a few kWh per hour, and the use cost is low.
Research and experiments show that the laser cleaning technology for the maintenance of military equipment has broad prospects. The laser cleaning machine launched by Shengtong Intelligent Laser Equipment Group can be applied to various application scenarios in aerospace, and customers can choose suitable laser cleaning machine models according to different needs.
