There are 4 kinds of laser cleaning methods:

1. Laser dry cleaning method, that is, use of pulsed laser radiation decontamination;

2. Laser + liquid film method, that is, first deposited a layer of liquid film on the surface of the substrate, and then use the laser radiation decontamination;

3. Laser + inert gas method, that is, the laser radiation (at the same time) work with an inert gas blow to the substrate surface, when the dirt from the surface stripping will immediately be blown off the surface, in order to avoid surface contamination and oxidation;

4. Using the laser to loose dirt, and non corrosive chemical cleaning method.

At present, the former 3 methods are commonly used. The fourth methods are only found in the cleaning of stone relics in.

The world has been used for laser cleaning technology for stone material more than 10 years of history. In China, the stone material of laser cleaning started late. Due to the current investment in laser equipment is also more expensive, there is a certain degree of difficulty of the universal application. Because of the traditional cleaning methods can not match the advantages of laser cleaning technology, with mass production of the perfection of technology and equipment, laser cleaning technology will in the cleaning industry of stone material play an important role.
