※Principle of laser cleaning
Laser cleaning technology is the process of using laser beams to irradiate the surface of the workpiece to peel off or vaporize the surface dirt, rust coating, etc., and clean the surface of the workpiece to achieve the purpose. The thermal effect and vibration effect of the laser are more recognized.
The process of laser cleaning relies on the characteristics of the light pulse generated by the laser, based on the photophysical reaction caused by the interaction between the high-intensity beam, the short pulse laser, and the contamination layer. The physical principles can be summarized as follows:
1. The light beam emitted by the laser is absorbed by the contamination layer on the surface to be treated.
2. Absorption of large energy forms a rapidly expanding plasma (a highly ionized unstable gas), which generates shock waves.
3. The shock wave turns pollutants into fragments and is removed.
4. The light pulse width must be short enough to avoid heat accumulation that damages the surface to be processed.
5. Experiments show that when there are oxides on the metal surface, plasma is generated on the metal surface.
※The advantages of laser cleaning
Compared with traditional cleaning methods such as mechanical friction cleaning, chemical corrosion cleaning, liquid solid strong impact cleaning, and high-frequency ultrasonic cleaning, laser cleaning has obvious advantages.
1. Laser cleaning is a "green" cleaning method. It does not need to use any chemicals and cleaning fluids. The cleaned waste is basically solid powder, small in size, easy to store, recyclable, and can easily solve chemical cleaning belts. The coming environmental pollution problem;
2. The traditional cleaning method is often contact cleaning, which has mechanical force on the surface of the cleaned object, damages the surface of the object or the cleaning medium adheres to the surface of the object to be cleaned, and cannot be removed, resulting in secondary pollution. Laser cleaning is non-abrasive And non-contact makes these problems easy to solve;
3. The laser can be transmitted through optical fiber, coordinated with robots and robots, it is convenient to realize remote operation, and can clean the parts that are not easily reached by traditional methods. This can ensure the safety of personnel when used in some dangerous places;
4. Laser cleaning can remove various types of pollutants on the surface of various materials to achieve a cleanliness that cannot be achieved by conventional cleaning. And it can also selectively clean the contaminants on the surface of the material without damaging the surface of the material;
5. Laser cleaning efficiency is high, saving time;
6. Although the initial investment of the laser cleaning system is relatively high, the cleaning system can be used stably for a long time, the operating cost is low, and more importantly, it can be easily automated.
※Laser cleaning application
As a new cleaning technology, laser cleaning has many advantages such as environmental protection and high efficiency. It is one of the main development directions of laser technology today. It has a wide range of application prospects in aerospace, shipbuilding, rail transit, automobile manufacturing, steel manufacturing , Electronics industry, medical and cultural relics restoration, etc. have been very good applications.

※Practical application
Laser cleaning can be used not only to clean organic pollutants, but also inorganic substances, including metal rust, metal particles, dust and so on. Here are some practical applications. These technologies are very mature and have been widely used.
1. Mold cleaning:
Every year, tire manufacturers all over the world manufacture hundreds of millions of tires. The cleaning of tire molds during the production process must be rapid and reliable to save downtime. Traditional cleaning methods include sandblasting, ultrasonic or carbon dioxide cleaning, etc., but these methods usually have to cool the high-heat mold for several hours, and then move it to the cleaning equipment for cleaning. It takes a long time to clean and easily damages the accuracy of the mold. . Using the laser cleaning method, because the laser can be transmitted by optical fiber, it is flexible in use; because the laser cleaning method can be connected with optical fiber to clean the dead corner of the mold or the part that is not easy to clean, it is convenient to use;
2. Cleaning of weapons and equipment:
Laser cleaning technology is widely used in weapon maintenance. The laser cleaning system can remove rust and pollutants efficiently and quickly, and can select the cleaning parts to realize the automation of cleaning. Using laser cleaning, not only the cleanliness is higher than the chemical cleaning process, but also almost no damage to the surface of the object.
3. Cleaning in the electronics industry:
The electronics industry uses lasers to remove oxides: The electronics industry requires high-precision decontamination, and lasers are particularly suitable for oxide removal. Before the circuit board is soldered, the component pins must be thoroughly deoxidized to ensure the best electrical contact, and the pins must not be damaged during the decontamination process. Laser cleaning can meet the requirements of use, and the efficiency is very high.
4. Precise deesterification cleaning in the precision machinery industry:
The precision machinery industry often needs to remove the esters and mineral oils used for lubrication and corrosion resistance on the parts, usually by chemical methods, and chemical cleaning often still has residues. Laser deesterification can completely remove esters and mineral oil without damaging the surface of the part. The removal of pollutants is completed by shock waves, and the thin layer of oxide on the surface of the parts explosively vaporizes to form shock waves, resulting in the removal of dirt, rather than mechanical interaction. The material is thoroughly deesterified and used for the cleaning of mechanical parts in the aerospace industry. Laser cleaning can also be used to remove oil and ester in the processing of mechanical parts.
5. Pipeline cleaning in nuclear power plant reactor:
The laser cleaning system is also used in the cleaning of pipelines in nuclear power plant reactors. It uses optical fibers to introduce high-power laser beams into the reactor to directly remove radioactive dust, and the cleaned materials are easy to clean. And because it is operated remotely, the safety of the staff can be ensured.
In summary, laser cleaning plays an important role in many fields. Laser cleaning has obvious advantages compared with traditional cleaning methods such as mechanical friction cleaning, chemical corrosion cleaning, liquid solid strong impact cleaning, and high-frequency ultrasonic cleaning. It is efficient, fast, low-cost, and has low thermal and mechanical load on the substrate. The cleaning is non-damaging; the waste is recyclable, no environmental pollution; it is safe and reliable, and does not harm the health of the operator; it can remove a variety of different thicknesses and differences The coating of the components; the cleaning process is easy to realize automatic control, and realize remote remote control cleaning and so on. It can be seen that laser cleaning technology will gradually replace some of the traditional cleaning methods in the future.
