Laser cleaning on the application of cultural relics

Traditional means of cleaning will cause irreversible damage to cultural relics, just how much damage is the problem. Laser heritage cleaning is different, laser cleaning uses the characteristics of the laser beam, through the focusing system can make the laser beam gathered into different sizes of spot diameter, in the laser energy under the same conditions, different spots of the laser beam, the resulting energy density or power density is different, so that you can easily control the cleaning of the laser energy required. The laser can achieve a high degree of concentration in time and space. Laser cleaning utilizes these characteristics to effectively remove contaminants. The contaminants are instantly stripped from the surface of the artifacts, thus realizing the cleaning of the artifacts.

Another important aspect: it is a harmless cleaning method - the material on the surface of cultural relics and attached to the pollutants on the absorption of laser beams are different, this difference allows people to distinguish between the pollutants and cultural relics surface material, so as to accurately control the cleaning of the laser energy required to do not harm the cultural relics, but also clear off the pollutants. At present, this technology has been widely used in stone cultural relics, paintings and other fields.

Laser cleaning equipment is a new generation of high-tech products on the surface, easy to install, control and automation. Simple operation, turn on the power, open the equipment, can be no chemicals, no media, no dust, no water cleaning, can be automatically focused, fit the surface cleaning, cleaning surface cleanliness and other advantages, able to remove the surface of the object resin, oil, stains, dirt, embroidery, coating, plating, paint.
