Portable laser cleaning machines usually refer to handheld or suitcase-style laser cleaning equipment with a handheld cleaning head, stable fiber optic transmission and cooling devices. Their main advantages are portability, flexibility, environmental friendliness, non-destructiveness, and they are highly suitable for outdoor, high-altitude, complex facades and targeted removal of graffiti stains.
Why choose laser cleaning for painting Removal?
1. Without damaging the original substrate, preserving the original appearance
Paintings often appear on walls, stone surfaces, ancient buildings, transportation facilities, and relief surfaces. Chemical agents can corrode the surface of the substrate, while high-pressure water guns or sandblasting to remove paint can cause the wall plaster to flake off and the decorative finish to be scratched. However, laser non-contact and precise paint removal only removes the paint of the graffiti, leaving the original surface intact. This method is particularly suitable for old buildings and complex-shaped walls.
2. Compliant with environmental protection standards
No use of strong acids, strong bases, or cleaning agents. No wastewater or chemical residues are produced. Only a small amount of dust is generated. If a dust collection device or blowing equipment is used, it can be handled. It will not pollute the environment, corrode surrounding plants, nor cause urban pollution due to chemical waste. It complies with environmental protection and municipal environmental protection requirements.
3. Flexible and adaptable to complex scenarios,comprehensive cleaning operation
The portable laser cleaning machine can be easily moved by one person. The gun head is lightweight, and the optical fiber wiring is flexible. It can clean areas such as high-altitude walls, corners, crevices, uneven surfaces, utility poles, bus stop signs, etc., which are difficult to clean with conventional tools. It can be operated in outdoor, street, and rooftop environments.
4. Comprehensive use results in lower costs.
Almost no consumables. The laser has a lifespan of up to 100,000 hours, eliminating the need for frequent purchases of chemicals and abrasives;
One-time purchase for long-term use, saving the cost of repeated purchases of chemicals and waste disposal, as well as reducing the cost of repair and rework after substrate damage.
5. Safe operation, user-friendly
There are no safety hazards caused by corrosive liquids, high-pressure water flow, or grinding dust. Standard safety locks and protective accessories are provided. The operation is simple, and beginners can quickly master it, reducing the risk of injury for operators.
6. The cleaning effect is stable with minimal color difference.
The laser parameters can be adjusted, allowing for layer-by-layer removal of the pigment. There will be no issues such as local corrosion, wallpaper blooming, or significant color differences. After cleaning, the surface is neat and beautiful, with a visual quality far superior to traditional methods.
After 10 seconds of laser cleaning, it can be seen that the paint has been basically removed and the original color of the wall has been restored.
200w Portable Laser Rust Removal Machine's Cleaning Effects---Rust Removal / Wood Cleaning
At the same time, we also conducted tests on laser rust removal and wood cleaning. During the tests, we found that the 200w portable laser cleaning machine can meet the requirements of various unconventional working environments, such as factory fences and garage floors. All that is needed is to provide power, and cleaning operations can be carried out. It is highly practical.
During the cleaning process, the parameter settings are also an important factor affecting the cleaning effect. The average power, pulse frequency (repetition frequency), pulse width (pulse width), single pulse energy, etc. are all core parameter settings that require continuous small-scale experiments to be adjusted to the appropriate parameters.
Among them, the average power parameter: In actual operation, we found that for thin pigments / small advertisements: set within 100W; for thick graffiti, multi-layer spray painting: 100–200W; for hard substrates (metal, tiles), it can be appropriately increased, while for walls and ancient building stones, it should be kept relatively low.Pulse frequency: For regular graffiti, the setting is 50–200Hz; for thick hard paint layers, it is adjusted to 20–80Hz.For cleaning graffiti, a narrow pulse width (60–120ns) is generally used.
