Laser cleaning works according to the principle of pulsed laser ablation: the laser pulse is sent to the surface and penetrates the contaminant to then reflect on the substrate. Through a combination of different processes a layer of gas is formed between the substrate and the contaminant, which will cause the contaminant to break free. The combination of these processes is called ablation.
Netalux developed a methodology to control this process and to capture the released particles almost immediately. This immediate capture means that the contaminants are not being spread around. There are no large air movements being created, and the contamination of the environment is reduced to a minimum.
Because we use a pulsed laser beam, there is almost no heating up of the substrate: the light pulses are so short that the substrate does not heat up, or in case it heats up it’s minimal (depending on the material of the substrate of course).
WHAT LASER CLEANING CAN’T DO
- Laser cleaning doesn’t offer a magical solution for every surface treatment issue. So don’t believe everything you see on the internet!
- Laser cleaning has (like every technique) its limitations and will not always be the fastest of all cleaning techniques.
- Laser cleaning machines will have a hard time removing heavy corrosion and wil remove thick layers of coating at a lower speed.
- You can’t learn the technology in just a few hours. Your operators will need thorough training, since it takes time and experience to be able to gain speed and efficiency.
WHAT LASER CLEANING CAN DO
- Our laser cleaning machines are a great tool in challenging environments where conditions are dangerous for people or threatening the environment.
- If used well, it’s a safe and stable technology that allows for cleaning or treating surfaces without damaging the substrate.
- The setup is easy. Plug & Play!
- The results are most often cleaner because cleaning with light leaves no residue.
- You’ll be able to work without creating any air movements; safeguarding adjacent personnel and installations.
- Laser cleaning creates no secondary waste and you’ll have a lot more control over direct suction making sure you can safely capture the contaminant you’re removing.
All of this will reduce the total cost of ownership, and will improve the efficiency of the project.
