Laserpuhdistus

Laserpuhdistus, also known as laser cleaning, is a non-contact method used for removing contaminants from surfaces. It utilizes a laser beam to ablate or vaporize unwanted material without damaging the underlying substrate. The process works by directing a high-intensity laser pulse onto the surface. The absorbed laser energy rapidly heats the contaminant layer, causing it to expand and detach from the substrate. Depending on the application, the ablated material is either carried away by the laser-induced plume or can be captured by a vacuum system.

This technique is highly versatile and can be employed on a wide range of materials, including metals, plastics, stone, and ceramics. Laser cleaning offers several advantages over traditional methods like abrasive blasting or chemical cleaning. It is environmentally friendly as it does not generate waste byproducts such as solvents or dust. Furthermore, it is highly precise, allowing for targeted cleaning of specific areas and avoiding damage to sensitive surfaces. The process is also fast and can be automated for industrial applications.

Common applications for laser cleaning include rust and paint removal, de-coating, cleaning of molds and tools, surface preparation for welding or bonding, and the restoration of historical artifacts. The specific laser parameters, such as wavelength, pulse duration, and power, are adjusted based on the type of contaminant and the substrate material to ensure effective and safe cleaning. As laser technology advances, laser cleaning is becoming an increasingly popular and sustainable solution across various industries.
