1.Laser degreasing mechanism:
We use handheld laser cleaning machine for laser degreasing. Laser degreasing is mainly divided into ablation mechanism, vibration stripping mechanism and blasting mechanism. The ablation mechanism is that after the substrate absorbs the energy of the laser, the temperature of the material rises rapidly above its melting and boiling points, and then the material is vaporized and decomposed, leaving the surface of the substrate. When the laser beam is irradiated to the surface of the workpiece, most of the laser energy can be absorbed by the oil, and the temperature of the oil rises instantly, reaching the vaporization point or combustion point, causing it to burn off, and ultimately achieving the purpose of cleaning.
The vibration stripping mechanism of handheld laser cleaning machine refers to the different response of oil stains and surface metals to thermal expansion under the action of laser. In the process of rapid cooling after thermal expansion, a stress difference occurs between the oil stains and the substrate, and the accumulation and release of stress will propagate into vibration waves, thereby forming a strong detachment stress at the contact interface between the cleaned object and the substrate, so that the cleaned object can overcome its binding force with the substrate surface and leave the substrate.
The blasting mechanism of handheld laser cleaning machine refers to the rapid increase in temperature after the substrate absorbs the energy of the laser beam, reaching the vaporization temperature of the oil at the interface or the vaporization temperature of the substrate. The resulting steam and other gases expand instantly, and the high-speed expansion pressure wave jets the oil out of the surface of the substrate to achieve the effect of cleaning.
2.Laser Degreasing related research:
At present, the application scenarios of laser degreasing are more complex, and the materials and oil stains are different. Due to the differences in the absorption rate of different substrates and different oil stains on the laser, it is necessary to determine the cleaning threshold and damage threshold of different materials in advance in practical applications. This is crucial for the determination of the laser process.
3.Feiying handheld laser cleaning machine:
For thin oil stains, Feiying Laser's handheld laser cleaning machine can complete the degreasing requirements well. For thick oil stains, the handheld laser cleaning machine can ensure the cleaning effect while being more efficient. Our handheld laser cleaning machine can also achieve the cleaning effect of other low-power equipment, so our handheld laser cleaning machine can basically meet most of the degreasing needs.
With the continuous maturity of laser technology and the gradual reduction of costs, the application prospects of our handheld laser cleaning machine equipment in the field of rust removal and degreasing will be broader. In the future, laser cleaning technology is expected to achieve deep penetration in many fields such as aerospace, automobile manufacturing, and rail transit, and promote the development of the industrial cleaning industry in a more efficient, environmentally friendly and intelligent direction. At the same time, with the integration and application of artificial intelligence, big data and other technologies, laser cleaning machines will also be more intelligent and automated, providing users with more convenient and accurate cleaning solutions.
