1、Laser cleaning principle
High energy laser cleaning machine is absorbed by the surface smear layer, with the high temperature, a rapidly expanding plasma is formed to generate shock waves, pollutant become debris and are removed.
Laser cleaning machine use high energy laser beam to irradiate the surface smear layer, with the high temperature, the rust, oil, painting and coating can evaporate or peel off to achieve the cleaning purpose.
The pulse width of the laser light is short enough and the absorption rate of the base materials to the laser light is very low, most of the laser light is reflected. Laser cleaning process is completed instantly, so the base materials will not have obvious temperature rise, no damage to the base materials. Laser cleaning machine can clean rust, oil, painting and coating etc.
2、Characteristics of laser cleaning
- Non contact cleaning, no damage to the base materials.
Precise cleaning, can realize precise position, precise size and selective cleaning.
No need of any chemical cleaning fluid and consumables. It is green, safe, convenient and environmental friendly.
High cleaning efficiency, saving time.
The laser cleaning system is stable and maintenance free.
Anti shake and anti spot functions, the cleaning surface is uniform, and will not produce zebra crossing, scars and other effects that affect the appearance.
