2 Understanding Laser Wood Stripping Technology
Laser wood stripping technology provides a sophisticated and efficient method for removing coatings, paint, and other contaminants from wood surfaces. This technique leverages the precision and power of lasers to clean wood without causing damage. Here’s an in-depth look at how laser wood strippers work and the types of lasers used in wood stripping.
2.1 How Do Laser Wood Strippers Work?
Laser wood strippers operate based on the principle of laser ablation, where high-intensity laser beams are used to remove unwanted material from a surface. Here’s a step-by-step explanation of the process:
Laser Generation:
- A laser source generates a coherent and monochromatic beam of light. The type of laser (fiber, CO2, Nd:YAG, etc.) determines the specific properties of the beam, such as wavelength and power.
Beam Delivery and Focusing:
- The laser beam is directed and focused onto the wood surface using an optical delivery system, which may include lenses, mirrors, and fiber optics. The beam is focused to a small spot size to achieve high energy density.
Absorption and Heating:
- The targeted coating or contaminant on the wood absorbs the laser energy. Different materials absorb laser light differently, but most coatings and paints absorb it efficiently.
Ablation and Vaporization:
- The absorbed energy causes rapid heating, leading to the vaporization or sublimation (transition from solid to gas) of the coating material. This process removes the unwanted layer without affecting the wood beneath.
Material Ejection:
- As the coating material vaporizes, the resulting gas and small particles are ejected from the surface. Fume extraction systems are used to capture and filter these byproducts, maintaining a clean work environment.
Controlled Removal:
- The laser parameters (power, pulse duration, and scanning speed) are precisely controlled to ensure that only the coating is removed, leaving the wood intact. This allows for layer-by-layer removal if necessary.
2.2 Types of Lasers Used in Wood Stripping
