The emergence of laser cleaning technology is a revolution in cleaning technology. The laser cleaning technology takes advantage of the advantages of high energy density, high precision and efficient transmission of laser, and has obvious advantages over traditional cleaning technology in terms of cleaning efficiency, cleaning accuracy, cleaning location, etc. It can effectively avoid environmental pollution caused by chemical corrosion cleaning and other cleaning technologies, and will not damage the substrate.
Traditional cleaning technologies include mechanical friction cleaning (sandblasting cleaning, high-pressure water gun cleaning, etc.), chemical corrosion cleaning, ultrasonic cleaning, dry ice cleaning, etc. These cleaning technologies have been widely used in all walks of life, such as sandblasting cleaning, which can remove metal rust, metal surface burr, circuit board surface anti-rust paint, etc. by selecting abrasives with different hardness. Chemical corrosion cleaning technology is widely used for equipment surface oil dirt cleaning Boiler scale cleaning, oil pipeline cleaning and other fields. Although these cleaning technologies have been developed and matured, there are still some problems, such as sandblasting cleaning is easy to cause damage to the treated surface, chemical corrosion cleaning will cause environmental pollution, and improper treatment will cause corrosion of the cleaned surface.
What is laser cleaning? Laser cleaning is the process of removing materials from solid (or sometimes liquid) surfaces by laser beam irradiation. At low laser flux, the material is evaporated and heated or sublimated by the absorbed laser energy. At high laser flux, materials are usually converted into plasma. Usually, laser cleaning means the removal of materials with a pulsed laser, but if the laser intensity is high enough, the material can be ablated with a continuous wave laser beam. The excimer laser with deep ultraviolet light is mainly used for optical ablation. The laser wavelength used for optical ablation is about 200 nm. The depth of absorbed laser energy and the amount of material removed by a single laser pulse depend on the optical properties of the material and the laser wavelength and pulse length. The total mass of each laser pulse ablated from the target is usually called the ablation rate.
