There are four main laser cleaning methods:
① Laser dry cleaning, that is, using pulse laser direct radiation decontamination;
② The method of laser + liquid film is to deposit a layer of liquid film on the surface of the substrate and then decontaminate it with laser radiation;
③ The method of laser + inert gas is to use inert gas to blow to the surface of the substrate at the same time of laser radiation. When the dirt is peeled off the surface, it will be blown off the surface immediately by the gas to avoid the surface pollution and oxidation again;
④ After using laser to loosen the dirt, clean it with non corrosive chemical method.
The first three methods are most commonly used. The fourth method is only found in the cleaning of stone relics.
In the world, laser cleaning technology has been applied to stone materials for more than ten years. In China, the laser cleaning of stone materials started late. Because the investment of laser equipment is still expensive, it is difficult to popularize it. However, the laser cleaning technology has the advantages that the traditional cleaning methods can not compare with. With the continuous improvement of technology and the mass production of equipment, the laser cleaning technology will play an important role in the cleaning industry of stone materials.
