Laser cleaning technology and application in industry
2023-05-06
Laser is the 20th century, after atomic energy, computer, semiconductor, another major invention of mankind, the original Chinese name is called "laser", the principle of laser as early as 1916 has been discovered by the famous American physicist Albert Einstein. In 1964, according to the suggestion of Qian Xuesen, a famous Chinese scientist, "light stimulated radiation" was renamed "laser".
Principle of laser cleaning
Existing defect
Advantages of laser cleaning
Traditional industrial cleaning
1 .Go green
Laser cleaning does not need to use any chemical agents and cleaning fluid, the waste generated is basically particles and gas can be simple through the portable exhaust fan waste collection and purification treatment can easily solve the problem of environmental pollution caused by chemical cleaning.
2. Use effect
The traditional cleaning method is often contact cleaning, there is mechanical force on the surface of the cleaning object, the surface of the damaged object or the cleaning medium is attached to the surface of the cleaned object, can not be removed, resulting in secondary pollution, laser cleaning without grinding and non-contact, no thermal effect will not destroy the base, so that these problems are easily solved.
3. Easy to operate
Laser can be transmitted through optical fiber, and robot hand and robot coordination, convenient to achieve remote operation, can clean the traditional method is not easy to reach the parts, which can be used in some dangerous places to ensure the safety of personnel.
Step 4: Convenience
Laser cleaning can remove various types of pollutants on the surface of various materials, and achieve the cleanliness that conventional cleaning can not reach. It can also selectively clean the contaminants on the surface of the material without damaging the surface.
5. Cost advantage
Although the purchase of laser cleaning system in the early one-time investment is high, but the cleaning system can be used for a long time, no consumables consumption, low operation cost, only need to clean or replace the lens regularly in the later period, low maintenance cost, close to maintenance free. More importantly, it can be easily automated.
Typical applications of laser cleaning include: mold cleaning, industrial rust removal, paint and film removal, pre-welding and post-welding treatment, precision parts of ester removal, electronic components decontamination and oxidation layer, cultural heritage cleaning. Widely used in metallurgy, mold, automobile, hardware tools, transportation, building appliances, machinery and other industries.
