How does the mysterious laser perform cleaning work? Laser rust removal: Using the high energy, high frequency, and high power characteristics of lasers, high energy is instantly deposited in a very small area, and the oxide layer is burned by high temperature, which is also called laser cleaning.
Its physical principles can be summarized as follows: 1) The light beam emitted by the laser is absorbed by the contaminated layer to be treated. 2) The absorption of large energy forms a rapidly expanding plasma, generating shock waves. 3) The shock wave breaks the contaminants into fragments and removes them. 4) The width of the light pulse must be short enough to avoid heat accumulation and damage to the surface to be treated. Laser can clean the corroded surface of the workpiece through a high-energy beam, which is similar to a small explosion on the surface of the workpiece. The stains and rust on the surface are turned into gas and dust and adsorbed away, without damaging the bottom material of the workpiece to maintain its original low temperature!
