Laser cleaning machines have significant effects and advantages in cleaning ship rust. It uses a high-energy laser beam to irradiate the rust on the surface of the hull, and through the thermal effect, photochemical effect, shock wave effect, etc. generated by the interaction between the laser and the material, the rust quickly heats up, expands, vaporizes or peels off, thereby achieving the purpose of cleaning. The main advantages of laser cleaning rust on ship hulls include:
1. Efficient and environmentally friendly: Laser cleaning does not require chemical solvents, avoiding environmental pollution and wastewater treatment problems caused by chemical cleaning. At the same time, it has high cleaning efficiency and can clean large areas or deep rust in a short time, significantly shortening downtime.
2. Non-destructive cleaning: The non-contact characteristics of laser cleaning prevent mechanical scratches or damage to the surface of the object to be cleaned during the cleaning process. It is especially suitable for cleaning precision parts with high precision requirements.
3. Precise control: The laser beam can be flexibly adjusted to achieve precise cleaning of small areas or complex structures to meet diverse cleaning needs.
4. High degree of automation: Combined with advanced control systems and robotic technology, laser cleaning equipment can realize automated operations, reduce manual intervention, and improve production efficiency and safety.
In practical applications, the application of laser cleaning technology in the shipbuilding industry has achieved remarkable results. For example, the underwater laser cleaning process developed by the Laser Center Hannover (LZH) can effectively remove biological contaminants from ship hulls without damaging the hull's underlying coating. In addition, laser cleaning technology can also be used to clean the grooves, weld bead surfaces, local corrosion areas and small spaces inside the ship, which is more efficient than traditional grinding technology.
In general, laser cleaning technology has shown strong competitiveness and broad application prospects in the field of ship cleaning due to its high efficiency, environmental protection, non-destructive cleaning and other characteristics. With the continuous advancement of technology and the continuous expansion of the market, laser cleaning technology is expected to play a more important role in the field of ship cleaning in the future.
