Laser cleaning technology uses nanosecond or picosecond pulsed high-energy density laser to irradiate the surface of the workpiece, so that the surface of the workpiece absorbs the focused laser energy in an instant, forming a rapidly expanding plasma, making the surface oily, rust, dust. Substances such as slag, coating, oxide layer or film layer instantly evaporate or fall off, which can quickly and efficiently remove attachments or excess coating from the workpiece and achieve the purpose of cleaning the workpiece.

Laser cleaning is a cutting-edge technology based on the interaction between laser beams and other substances. Compared with traditional cleaning methods such as chemical cleaning, mechanical cleaning, dry ice cleaning, and ultrasonic cleaning, it has significant advantages such as high efficiency, speed, and low cost. The thermal load and mechanical force generated on the workpiece are very small, which will not cause damage to the workpiece, and the waste can be recycled in time, which will not cause pollution to the environment, and will not cause harm to the operator, and can also realize remote automatic remote control cleaning.

Laser cleaning can be used not only to clean organic pollutants, but also to clean inorganic substances, including metal rust, metal particles, dust, etc.
