Pulsed laser cleaning machine and continuous laser cleaning machine

At present, the laser cleaning machine on the market has pulsed laser cleaning machine and continuous laser cleaning machine, both of which can remove the dirt on the surface of the substrate, the only difference is that the pulsed laser cleaning machine is a pulsed laser emitter, and the continuous laser cleaning machine is a continuous laser emitter. The pulse laser cleaning machine can achieve zero damage to the substrate after cleaning dirt, which is suitable for cleaning products with high requirements for the substrate surface; The continuous laser cleaning machine is almost damaged for the substrate, and is suitable for large-area cleaning, such as steel plate rust removal, paint removal, shipyard rust removal, etc.So, what is the difference between continuous laser cleaning machines and pulsed laser cleaning machines?

1. The working principle of continuous laser cleaning machine and pulse laser cleaning machine is different.Continuous laser cleaning machine by constantly irradiating the laser beam, so that the surface of the workpiece dirt, oil stains and other organic matter pyrolysis evaporation, so as to achieve the cleaning effect. The pulsed laser cleaning machine is through intermittent laser beam irradiation, producing high intensity heat pulse, so that the surface of the stain explosion evaporation.
2. Continuous laser cleaning machine and pulse laser cleaning machine are also different in cleaning speed and cleaning effect.Continuous laser cleaning machine is suitable for cleaning large area, thin thickness stains, cleaning speed, good effect. However, for thick stains and oxides and other inorganic substances, the cleaning effect of continuous laser cleaning machine is not as good as that of pulsed laser cleaning machine. Pulsed laser cleaning machine due to the higher energy density of the laser beam, it can instantly evaporate the oxide on the surface, and the cleaning effect is more thorough. However, the cleaning speed of the pulsed laser cleaning machine is relatively slow, and it is suitable for cleaning small areas and thick stains.
3. Continuous laser cleaning machine and pulse laser cleaning machine are also different in the cost of use.Pulsed laser cleaning machine: usually requires a high equipment cost, because it can achieve zero damage to the substrate, suitable for cleaning products with high requirements for the substrate surface.
Continuous laser cleaning machine: Compared with pulse laser cleaning machine, continuous laser cleaning machine equipment cost is lower, suitable for large-scale industrial cleaning needs.
4. Continuous laser cleaning machine and pulse laser cleaning machine are also different in operating requirements.Pulsed laser cleaning machine: the operator needs to have certain professional knowledge and skills to ensure safe operation. Because the pulsed laser cleaning machine has the characteristics of high energy and short action time, special attention needs to be paid to safety during operation.
Continuous laser cleaning machine: The operation is relatively simple, and the professional skills of the operator are low. However, it is also necessary to pay attention to the radiation and safety issues of the laser beam.In summary, there are significant differences between pulsed laser cleaning machines and continuous laser cleaning machines in many aspects. When choosing which cleaning machine to use, it is necessary to comprehensively consider factors such as specific cleaning needs, cost budget and the technical level of the operator.
