Laser cleaning is a new type of cleaning, which uses the energy of the laser to remove dirt, dust and attachments on the surface of the object. Compared with traditional cleaning methods, laser cleaning has higher cleaning efficiency and lower cost, and does not cause damage to the surface of the object, so it is widely used in various fields.
The principle of laser cleaning is based on the energy of the laser can be absorbed by the surface of the object and converted into heat energy, so as to rapidly heat and vaporize dirt, attachments, etc., to achieve the purpose of cleaning. In this process, the energy of the laser is able to penetrate into tiny parts of the surface of the object, so it is possible to clean objects of various shapes and sizes.
Compared with traditional cleaning methods, laser cleaning has the following advantages:
1. No chemical solution is required. There is no environmental pollution caused by chemical cleaning. It is a new technology to replace pickling and phosphating. New processes, new methods.
2. The solid powder formed by the waste after cleaning is small in size and easy to handle, which has no further pollution to the environment. Green environmental protection is the reform and development trend of industrial cleaning.
3. Laser cleaning is non-contact, and can be transmitted through optical fiber, combined with robots or manipulators, which is easy to achieve long-distance operation. It is an ideal solution for cleaning and maintenance of ships, aircraft, weapons and equipment.
4. Laser cleaning can clean different types of pollutants on the surface of various materials to achieve a high degree of cleanliness. It is a new application of surface engineering treatment. Pulsed laser is more suitable for titanium alloy surface cleaning in addition to oxide skin, stainless steel weld cleaning, stainless steel solder joint cleaning, precision parts before welding, welding surface cleaning, flange cleaning. Uv lasers are suitable for cleaning large components.
5. Laser cleaning is set through the threshold calculation parameters. No contact, no grinding, no thermal effect, no harm to the substrate human body, it's easy to operate, and especially suitable for cleaning molds and cultural relics.
6. It can effectively clean micron pollution particles, which is suitable for precision instruments, precision parts cleaning.
7. Laser cleaning equipment can be used for a long time, and do not need consumables, which only need a small amount of power. It has low maintenance and operation costs, and can easily achieve automated operation, which can be used indefinitely at a time.
8. Laser cleaning and physical dry cleaning can replace traditional industrial cleaning which causes water waste, and can replace traditional surface treatment which requires cleaning fluid and detergent, which eliminate ODS ozone-depleting substances. It's a low-carbon, water and energy saving cleaning method.
9. Pickling, sandblasting and other traditional cleaning processes will inevitably cause obvious damage to the surface of the substrate and is not suitable for cleaning 30mm below the sheet material which is below 30mm. However, laser cleaning can play a big role.
10. Laser cleaning has strong flexibility and controllability. Through different parameter Settings, the same laser cleaning machine can make the surface rough and improve the adhesion. Different laser power, frequency, aperture, focal length, etc. should be kept as little as possible and not exceed the limit, which can increase efficiency and reduce costs.
