Laser rust removal machine, in simple terms, is a kind of equipment that uses a high-energy laser beam to interact with the surface of an object to remove surface contaminants, coatings, rust and other impurities. It breaks the limitations of traditional cleaning methods and has brought huge changes to the cleaning industry with a brand new, efficient and environmentally friendly concept. Today, let us first study the mechanism of the interaction between laser light and matter.
Laser rust removal machine can achieve efficient cleaning. The core of laser rust removal machine lies in the unique interaction mechanism between laser and matter, including photothermal effect, photochemical decomposition and plasma shock wave effect.
The photothermal effect of laser rust removal machine is the most common mechanism of action in laser cleaning. When the laser beam of the laser rust removal machine hits the surface of an object, the contaminants or coatings on the surface absorb the energy of the laser, and the light energy is quickly converted into heat energy. Taking the rust cleaning of the metal surface as an example, after the rust layer absorbs the laser energy, the temperature rises sharply, reaching the melting point or even boiling point of the rust layer in a very short period of time, causing the rust layer to quickly melt and vaporize, thereby detaching from the metal surface. This is just like in a hot summer, ice cubes will quickly melt and disappear when exposed to sunlight. The energy of the laser is like strong sunlight, which causes the pollutants to change their state quickly and realizes the purpose of cleaning.
The photochemical decomposition of laser rust removal machine uses a specific wavelength laser to react chemically with a substance to achieve cleaning. Certain organic pollutants, under the irradiation of a specific wavelength laser, the chemical bonds in their molecular structure will be interrupted by the energy of laser photons and decomposed into small molecular substances. These small molecular substances either evaporate into the air or exist on the surface of objects in a form that is easier to remove. For example, in the cleaning of cultural relics, for some organic dirt attached to the surface of cultural relics due to their age, by selecting a laser of the appropriate wavelength, it is possible to decompose the dirt molecules without damaging the body of the cultural relics and restore the original appearance of the objects.
The plasma shock wave effect of laser rust removal machine is a more complex but efficient mechanism of action. When the high-energy-density laser pulse of the laser rust removal machine hits the surface of an object, the material on the surface quickly absorbs energy and is instantly heated to an extremely high temperature to form a plasma.Plasma is a highly ionized gas with extremely high energy and pressure. At the moment the plasma is formed, it will expand sharply, producing a powerful shock wave. This shock wave is like an invisible brush, so that the laser rust removal machine can peel off surface contaminants from the object. In the aerospace field, for high-temperature coatings and stubborn pollutants on the surface of aircraft, the plasma shock wave effect can effectively remove them to ensure the performance and safety of aircraft.
