Pulse Laser Cleaning Machine Cleaning on Wood
A pulse laser cleaning machine can be used to clean wood surfaces effectively, removing contaminants like dirt, soot, paint, or oxidation without damaging the underlying material. Here’s how it works and what to consider:
How Pulse Laser Cleaning Works on Wood
Laser Ablation Principle:
Short, high-intensity laser pulses vaporize contaminants (e.g., paint, mold, soot) without burning the wood.
The process is non-abrasive, avoiding mechanical damage.
Works best on thin layers (e.g., old varnish, graffiti) rather than deep stains.
Adjustable Parameters for Safety:
Wavelength: Typically 1064 nm (IR) or 532 nm (green)—shorter wavelengths are safer for delicate wood.
Pulse Duration & Energy: Lower energy settings prevent charring.
Frequency: Lower frequencies (e.g., 20-100 Hz) reduce heat buildup.
Applications on Wood
✔ Restoration of Antique Wooden Furniture – Removes old paint, varnish, or dirt without sanding.
✔ Graffiti Removal – Cleans spray paint from wooden surfaces.
✔ Soot & Mold Cleaning – Effective after fire or water damage.
✔ Surface Preparation – Cleans wood before refinishing or bonding.
