Laser cleaning machine technology is a cleaning method that uses nanosecond or picosecond pulsed laser to irradiate the surface of a workpiece to be cleaned, causing the workpiece surface to instantly absorb focused laser energy, forming a rapidly expanding plasma (highly ionized unstable gas), causing oil stains, rust spots, dust residues, coatings, oxide layers or film layers on the surface to gasify or peel off, thereby efficiently removing surface attachments.
In the industrial application field, the object of laser cleaning machine is divided into two parts: substrate and cleaning material. The substrate mainly includes surface pollution layers of various metals, semiconductor chips, ceramics, magnetic materials, plastics, and optical components. The cleaning material mainly includes a wide range of application requirements for industrial fields such as rust removal, paint removal, oil removal, film/oxide layer removal, and resin, adhesive, dust residue cleaning.
Typical applications of laser cleaning machine include: mold cleaning, industrial rust removal, removal of old paint and film layers, pre welding and post welding treatment, ester removal of precision parts, decontamination and oxidation layer removal of electronic components, cultural relic cleaning, etc. Laser cleaning machine is widely used in industries such as metallurgy, molds, automobiles, hardware tools, transportation, construction appliances, machinery, etc.
At present, the widely used cleaning methods in the cleaning industry include mechanical cleaning, chemical cleaning, and ultrasonic cleaning. However, due to environmental protection constraints and high precision market requirements, their application is greatly limited. But laser cleaning machines have obvious advantages in various industries.
