Laser cleaning artifacts
Cultural relics are due to various circumstances and storage time. There will be a lot of dirt on the surface, such as: soil spots, rust spots, oil stains, water stains, sweat stains, etc. In the past, the commonly used cultural relic cleaning methods include mechanical cleaning and chemical cleaning. Mechanical means may result in the removal of materials from the work, and chemicals may penetrate the work of art, destroy the paint, and damage the cultural relics.These two methods may cause irreversible damage to the artwork.
Nowadays, laser cleaning utilizes the characteristics of the laser beam. The laser beam can be concentrated into different sizes of spot diameters through the focusing system. Under the same laser energy conditions, the laser beams with different spots have different energy densities or power densities. In this way, the laser energy required for cleaning can be easily controlled.( China Laser Cleaning Equipment on Sales Supplier)
Laser cleaning is a harmless cleaning method-the material on the surface of the cultural relics and the contaminants attached to it absorb the laser beam differently. This difference allows people to distinguish between the contaminants and the surface material of the cultural relics, so as to precisely control the cleaning requirements. The laser energy can not only harm cultural relics, but also remove pollutants.
At present, this technology has been widely used in stone cultural relics, oil paintings and other fields.
Advantages of laser cleaning:
1. Non-contact cleaning does not damage the base of the parts.
2. Precise cleaning can realize selective cleaning with precise position and precise size.
3. No chemical cleaning fluid, no consumables, safety and environmental protection.
4. The operation is simple, just power on, and it can be hand-held or cooperated with a manipulator to realize automatic cleaning.
