As a kind of cultural relic protection and restoration technology and equipment, laser cleaning technology has been widely used in the world, especially in the cleaning, protection and restoration of ancient buildings and their various construction surfaces, with many successful cases.
Laser cleaning is considered to be the most reliable and effective solution because it has the characteristics of no grinding, no contact, no thermal effect and suitable for all kinds of materials. At the same time, laser cleaning can solve the problem that traditional cleaning methods can not solve.
”The whole process of laser cleaning can be divided into four stages, namely, laser vaporization and decomposition, laser stripping, thermal expansion of pollutant particles, vibration of substrate surface and pollutant separation.“
"Cleaning operation is one of the essential key links in industrial production process, which plays an important role in improving product quality and prolonging service life. Under the background of vigorously promoting the transformation and upgrading of the manufacturing industry, the traditional cleaning methods have been unable to meet the application needs of the industrial field, especially in the high-end application field, the advanced laser cleaning technology has been paid more and more attention."
