How does laser rust removal work ?

It mainly uses the instantaneous high temperature corrosion produced by the laser beam on the product surface to ablate the rust, coating, oil and other surface substances on the product surface. The laser cleaning machine has a wide range of applications and is basically suitable for any industry. The laser cleaning machine uses a high-energy density laser beam to irradiate the surface of the workpiece to make the dirt, rust or coating on the surface evaporate or peel instantly, so as to achieve a clean, green, energy-saving and efficient industrial tool. It can quickly remove paint and Rust removal, removal of oxides, oil stains, oil stains and product residues, restoration and preservation of historical cultural relics, etc.

The high-power pulsed laser cleaning process relies on the characteristics of the optical pulse generated by the fiber laser, and is based on the photophysical reaction formed by the interaction between the high-intensity beam, the short-pulse laser, and the pollution layer. 

1. The beam emitted by the laser is absorbed by the pollution layer on the surface to be treated;

2. Absorption of large energy forms a rapidly expanding plasma (a highly ionized unstable gas), which generates shock waves;

3. The shock wave turns pollutants into fragments and is removed;

4. The light pulse width must be short enough to avoid heat accumulation that damages the processed surface;

5. When there is oxide on the metal surface, plasma is generated on the metal surface.
