Handheld Pulse Laser Cleaning Machine for Rust Removal of Ship Hull Shells

Product Description

Product Description

As a medium to high power industrial grade equipment, the technical parameters of the 200W laser cleaning machine directly determine the cleaning efficiency and scope of application. Taking the Wuhan Xiangming Laser CL-H-200 model as an example, the equipment uses a 1064nm wavelength fiber laser, with a single pulse energy of up to 1.5mJ (single-mode) or 5mJ (multi-mode), and stable heat dissipation is achieved through an air cooling system, with a power consumption of less than 1000W. The Jiangsu Guoyuan Laser GY-FLC200M model is equipped with a multi-mode pulse laser, with an adjustable pulse width of 2-500ns, a frequency range of 1-2000kHz, and supports 9 scanning modes. The spot diameter is about 10mm, and the scanning width can be adjusted from 5-100mm.
In terms of hardware design, 200W laser cleaning machines usually adopt a modular structure, including laser generation units, optical transmission systems, intelligent control systems, and cooling modules. For example, the world's smallest volume 200W model launched by Wheat Grain Intelligence is only 421 × 163 × 380mm in size, weighs 18.8kg, integrates distance and temperature measurement functions, and supports 48 hours of continuous operation. This type of design not only enhances the portability of the device, but also ensures stable performance of the laser during long-term operation through precise temperature control technology.
2, Working principle and cleaning mechanism
The core principle of laser cleaning is to use the interaction between high-energy laser pulses and material surfaces to achieve pollutant removal, which mainly includes the following three mechanisms:
Thermal evaporation effect
After the laser energy is selectively absorbed by the pollutant, it instantly heats up to the vaporization temperature (such as the vaporization temperature of rust Fe ∝ O₄ is about 1538 ºC), causing the pollutant to directly convert into a gaseous state and detach from the substrate. For oxide layers with a thickness less than 50 μ m, a 200W laser can complete single point cleaning within 0.1-0.3 seconds, with the heat affected zone controlled within 10 μ m.
Shock wave peeling
When pulsed laser is applied to pollutants, energy is released in a very short time (nanosecond level), generating a shock wave of up to 10 ^ 9 Pa, causing the pollutant layer to peel off due to stress fracture. This mechanism is particularly suitable for removing coatings with strong adhesion to the substrate (such as oxides before brazing automotive galvanized sheets), and the surface roughness Ra value after cleaning can be controlled at 1.6-3.2 μ m.
photochemical decomposition
For organic pollutants such as oil stains and adhesives, laser photon energy can break molecular bonds and decompose them into small molecule gases. For example, in the cleaning of KTL coatings on power batteries, a 200W laser achieves coating delamination and peeling through photochemical reactions, with an efficiency of 4-6 square meters per hour.
The 200W laser cleaning machine has become the mainstream choice in the industrial cleaning field due to its balance of power and accuracy, environmental advantages, and intelligent characteristics. With continuous technological breakthroughs such as AI parameter optimization and composite process integration, its application in high-end manufacturing fields such as new energy and aerospace will be further deepened. Enterprises need to comprehensively consider power configuration, automation requirements, and after-sales service when selecting equipment to maximize the return on investment. In the future, with the reduction of costs and the improvement of standards, 200W laser cleaning machines are expected to replace more than 30% of traditional cleaning processes, promoting industrial cleaning towards green and intelligent development.
