handheld laser cleaning machine does not use any chemical solvents or other consumables, environmentally friendly, safe operation

handheld laser cleaning machine 2000 watts can not only be used to clean organic pollutants, but also can be used to clean inorganic substances, including metal corrosion, metal particles, dust, etc. What is the technical principle of the laser cleaning machine 2000 watts?

The process of pulsed Nd:YAG laser cleaning depends on the characteristics of the light pulse produced by the laser, based on the photophysical reaction caused by the interaction between the high intensity beam, the short pulse laser and the pollution layer. Its physical principles can be summarized as follows:

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

2. The energy density of the laser can be adjusted to expand the dirt by heat. When the expansion force of the dirt is greater than the adsorption force of the dirt on the substrate, the dirt will break away from the surface of the object.

The optical pulse width must be short enough to avoid heat accumulation that would damage the treated surface.

4. The divergence Angle of the laser beam is small and the direction is good. The laser beam can be gathered into light spots of different diameters through the concentrating system.

5. The absorption of large energy forms a rapidly expanding plasma (highly ionized unstable gas), producing shock waves.

Each laser pulse removes a layer of pollution of a certain thickness. If the fouling layer is thick, multiple pulses are required for cleaning. The number of pulses required to clean the surface depends on the degree of surface contamination. An important result of the two thresholds is the self-control of cleaning. Light pulses whose energy density is higher than the first threshold will remove contaminants until they reach the substrate. However, because its energy density is below the destruction threshold of the substrate material, the substrate is not damaged. Wuhan Ruifeng photoelectric laser equipment is cost-effective, with many years of laser research and development experience, mature product technology, product performance safety and stability. Ruifeng photoelectric laser electricity always adhere to the "quality first, service second, price third" attitude, to provide customers with the best quality products and services.

The above is the technical principle of laser cleaning machine, laser cleaning and mechanical friction cleaning, chemical corrosion cleaning and other traditional cleaning methods compared, has obvious advantages. It is efficient, fast, low cost, on the substrate thermal load and mechanical load is small, cleaning for non-damage; No damage to the health of operators; The cleaning process is easy to realize automatic control and remote control cleaning. Thus, laser cleaning technology will gradually replace a part of the traditional cleaning way in the future.

Because laser cleaning does not use any chemical solvents or other consumables, it is environmentally friendly, safe to operate, and has many advantages:

1. Green environmental protection, do not need to use any chemical agents and cleaning fluid;

2. The cleaning waste is mainly solid powder, which is small in volume and easy to collect and recycle;

3. Cleaning waste smoke is easy to absorb and handle, with low noise and no harm to human health;

4. Non-contact cleaning, no medium residue, no secondary pollution;

5. Selective cleaning can be realized without damaging the substrate;

6. No working medium consumption, only consumption of electricity, use and maintenance cost is low;

7. Easy to achieve automation, reduce labor intensity;

8. Suitable for hard-to-reach areas or surfaces, hazardous or hazardous environments.
