The principle of laser cleaning involves using high-frequency, high-energy laser pulses to照射 the workpiece surface. The coating can instantly absorb the focused laser energy, causing surface oil, rust spots, or coatings to be stripped off immediately. It is a high-speed and effective method for cleaning surface contaminants or coatings, with the laser pulse's short action time not harming the metallic substrate under appropriate parameters.
Compared to traditional cleaning methods such as mechanical friction cleaning, chemical etching cleaning, liquid and solid high-impact cleaning, and high-frequency ultrasonic cleaning, laser cleaning offers distinct advantages.
1. Laser cleaning is a dry cleaning method, with no exhaust emissions, thus not causing environmental pollution. The cleaning residue is collected through a vacuum cleaner.
2. Effectively cleans sub-micron particles that adhere to surfaces, which are difficult to remove by other methods.
