Laser cleaning of statues is a method of cultural relics protection and restoration using laser technology. This technology uses high power laser to illuminate the pollutants on the surface of the statue, and uses thermal, mechanical and photochemical effects to remove the pollutants on the surface of the object. Compared with traditional cleaning methods, laser cleaning can accurately position and reach the cleaning of pollutants of a micron scale, can be cleaned for organic and inorganic pollutants, and basically does not generate additional pollution, has the advantages of intelligent controllability, automatic efficiency, and green environmental protection.
The application of laser cleaning technology in the field of cultural relics protection began in the 1970s, and the American scientist Asums and others first used laser to clean the hard shell pollutants on the stone surface of Venice, and confirmed its effect. Since then, laser cleaning technology has been widely used in the cleaning of various artifacts, including 15th century panel paintings, and its safety and effectiveness have been confirmed by Fourier transform infrared spectroscopy (FTIR) and combined gas chromatography-mass spectroscopy (GC-MS).
The development and application of laser cleaning technology are also progressing, for example, the experimental research on laser cleaning of pollutants on the surface of the Yungang Grottoes, and the research on laser cleaning of pollutants on the surface of stone cultural relics. These studies have shown that laser cleaning technology can effectively remove contaminants from the surface of cultural relics while protecting the original state of cultural relics.
Market trends, laser cleaning market size is growing year by year, is expected to 2028, the global market size will reach 6.217 billion yuan, is expected to average annual compound growth rate of 6.42% fluctuation. Because of its environmentally friendly and efficient features, laser cleaning technology has huge market potential, especially in the context of national environmental protection strategies such as "carbon neutrality" and "carbon peak," the market demand of laser cleaning is expected to continue to rise as a new type of environmentally friendly cleaning technology.
In summary, laser cleaning sculpture is an efficient and environmentally friendly cleaning technology that has broad application prospects in the field of cultural relic protection and restoration, and as the technology develops and market demand grows, laser washing technology will continue to play an important role in this field.
