![]() ![]() During laser cleaning, no toxins or dangerous substances are produced A sandblaster needs to be replenished with abrasive while a laser cleaning machines does not have any consumables No waste products whereas sandblasting creates a lot of dust, which should be collected together with abrasive - sand particles.No contact with the processed material.Let us specify the advantages of laser cleaning: In the second case, contaminants are dissolved by special solutions, which can disrupt surface and material structure. Non-contact treatment is also an advantage over chemical cleaning methods. But such impact can damage the product and disrupt its structure. Falling at high speed, they chip contaminants off the surface. When sandblasting, the contaminated material is “bombarded” with small sand particles. This makes laser cleaning different from the mechanical one, which can damage the product itself. The laser beam evaporates contaminants only. Thus, the processed material is not damaged. The nozzle does not touch the surface to be machined. The main advantage of laser cleaning is that it is noncontact. large parts of various equipment, for example planes, rockets, military equipment, oil production and refinery equipment, and so on.precious items: jewelry, precious stones, coins, archaeological artifacts.The laser is capable of removing insulative layer up to 1 mm small items: terminal, connectors, boards, wires, anilox.With a laser-cleaning machine, you can process: The technology is also successfully used to clean plastic, stone, ceramic, and concrete. This method is suitable for removing rust, varnish, paint, organic substances, oils, soot, and other contaminants. Laser cleaning equipment is mainly used to remove contaminants from metal surfaces. What materials can be cleaned with a laser? They collapse, detach from the metal, melt, and evaporate. Because of thermal energy of the laser, the strength of metal oxide molecules that form the rust decreases. If there is corrosion, it absorbs the beam. If there are no contaminations (for example rust), the laser beam is reflected. Operation of laser cleaning is based on exposing a light beam to the surface. It is necessary to prevent a laser source and a scanner (if it is a water-cooled type) from overheating during operation. The laser-cleaning machine should be completed with a cooling system, or a water chiller. This allows you to clean relief surfaces, for example metal bars. The scanner helps to focus laser radiation on the material surface, widen the laser beam, and give the light spot the desired shape.Ī system of mirrors inside the scanner collects the rays of light and then distributes them over the surface of the treated product. It can be in the form of a gun that an operator holds with one or two hands pointing it to the surface to be cleaned. When choosing equipment, you should consider your tasks and the available budget.Ī galvanometric scanner is an important component of laser cleaning equipment. The Virmer experts suggest using the Wattsan laser cleaning machines, which technical parameters guarantee excellent results. Thus, a laser-cleaning machine is suitable for removing rust from metal items and workpieces. The same fiber optic laser is used in metal cutters, laser markers and engravers. Laser cleaning refers to surface cleaning using a fiber optic laser. ![]()
