Introduction
100W Pulsed Air-Cooled Laser Cleaning Machine for Wood Paint Removal

This 100W pulsed fiber laser cleaning system efficiently removes paint from wood surfaces without damaging the substrate. Utilizing advanced air-cooling technology, it offers stable performance with adjustable parameters (pulse frequency: 20-100kHz, spot size: 0.2-2mm). Ideal for furniture restoration and woodworking, it provides:  
- Non-contact cleaning – No mechanical abrasion  
- Precise control – Selective paint layer removal  
- Eco-friendly – No chemicals or dust pollution  
- Compact design – Easy integration into production lines  

With fast processing speeds (1.5-2m²/h) and low thermal impact, it outperforms traditional sanding/chemical methods in quality and efficiency.  

1. Test background and purpose
The removal of paint from wood surfaces is an important process requirement in areas such as furniture renovation and ancient building restoration. Traditional chemical paint stripping and mechanical polishing methods have problems such as environmental pollution and substrate damage. Pulse laser cleaning technology has shown unique advantages in wood surface treatment due to its non-contact and selective removal characteristics.

10. Test Conclusion
100W pulse laser can effectively remove paint on the surface of wood, with a removal rate of>95% under the optimal process window

Controllable impact on substrate (heat affected zone<100 μ m, strength loss<5%)

Compared to traditional methods, it increases efficiency by over 30% and is more environmentally friendly

11. Application suggestions
Furniture restoration: Priority for partial restoration of high-end solid wood furniture

Preservation of ancient architecture: removal of paint layers suitable for finely carved areas

This test confirms the feasibility of pulse laser cleaning technology in wood surface treatment, providing a new technological choice for green wood product processing. The next step is to conduct systematic research on different tree species and establish a more comprehensive process database.
