First of all, the working principles of continuous laser cleaning machines and pulse laser cleaning machines are different. Continuous laser cleaning machines achieve cleaning effects by continuously irradiating laser beams to pyrolyze and evaporate organic matter such as dirt and oil stains on the surface of the workpiece. The pulse laser cleaning machine generates high-intensity heat pulses through intermittent laser beam irradiation, causing the stain surface to explode and evaporate.
Secondly, the cleaning speed and cleaning effect of continuous laser cleaning machines and pulse laser cleaning machines are also different. The continuous laser cleaning machine is suitable for cleaning large area and thin stains with fast cleaning speed and good effect. However, for thick stains and inorganic substances such as oxides, the cleaning effect of the continuous laser cleaning machine is not as good as that of the pulse laser cleaning machine. Due to the higher energy density of the laser beam, the pulse laser cleaning machine can instantly evaporate the oxides on the surface, resulting in a more thorough cleaning effect. However, the cleaning speed of the pulse laser cleaning machine is relatively slow and is suitable for cleaning small area and thick stains.
Finally, the cost of use of continuous laser cleaning machines and pulse laser cleaning machines is also different. The lasers of pulsed laser cleaning machines have a relatively short service life and need to be replaced more frequently, while the lasers of continuous laser cleaning machines have a relatively long service life and are less expensive.
