Laser cleaning machine is an effective and efficient method to remove rust and oxidized layer from the surface of metal materials. Through a high energy density laser to interact with specific substances, through the energy conversion generated by the force to overcome the bonding force between the cleaned material and the substrate, to photo-peeling, vaporization, ablation, plasma impact, vibration and other processes, so that the pollutants out of the surface of the material, to achieve the purpose of cleaning, and to be cleaned object itself is not damaged or will damage to be controlled in the minimum range.
The widespread use of laser cleaning stems largely from the need in the market for a non-toxic, non-abrasive cleaning method that can be used as an alternative to previous conventional cleaning.
Traditional Cleaning Methods – Mechanical Friction Cleaning, Chemical Erosion Cleaning cleaning, liquid solid strong impact cleaning, High-frequency ultrasonic cleaning
New cleaning technology – laser cleaning
1. High efficiency
Under the action of high-temperature energy, the sediment instantly vaporizes and evaporates from the surface of the object, and the time required is very short. The traditional cleaning methods, such as ultrasonic cleaning, after preheating, cooling and other processes before cleaning, the time required is long.
2. More environmentally friendly
Laser cleaning is a “green” cleaning methods, do not need to use any chemicals and cleaning fluids, cleaning down the waste is basically solid powder, small size, easy to store, recyclable, no photochemical reaction, will not produce pollution. Can easily solve the environmental pollution problems caused by chemical cleaning. Often an extractor fan can solve the problem of waste generated by cleaning.
3. Low cost
Laser cleaning speed, high efficiency, saving time; buy laser cleaning system, although the initial one-time investment is higher, but the cleaning system can be used for long-term stability, low operating costs, and more importantly, can be easily automated.
4. More convenient
Laser cleaning can remove various types of pollutants on the surface of various materials, to achieve the cleanliness that conventional cleaning can not be achieved. Moreover, it can selectively clean the pollutants on the material surface without damaging the material surface.
5. Good results
Traditional cleaning methods are often contact cleaning, cleaning the surface of the object has a mechanical force, damage to the surface of the object or cleaning medium attached to the surface of the object being cleaned, can not be removed, resulting in secondary pollution. Laser cleaning of non-abrasive and non-contact, non-thermal effect will not damage the substrate, so that these problems are solved.
6. Convenient control
Laser can be transmitted through fiber optics, with robots and robots, convenient to achieve long-distance operation, can clean the traditional methods are not easy to reach the parts. The pulse frequency, energy and wavelength can be selected according to the material to achieve better results.
7. High safety
Remote operation, no harmful substances and gases. The safety of the operator is guaranteed.
8. No abrasion
The cleaning process is non-contact and does not cause any abrasion to the metal surface of the substrate.
