1. teeb qhuav tu txoj kev, uas yog, ncaj tawg tawg tshem tej paug siv pulsed laser.
2. Laser + kua zaj duab xis qauv, uas yog, thawj tso ib cov kua zaj duab xis nyob rau qhov chaw ntawm lub substrate, thiab ces ntxuav nrog laser tawg.
3. Laser + inert roj txoj kev, uas yog, thaum lub laser tawg, lub inert roj yog cua tshuab mus rau qhov chaw ntawm lub substrate, thiab thaum cov av yog peeled tawm ntawm tus nto, nws yuav tsum tam sim ntawd tshuab tawm ntawm qhov chaw los ntawm cov roj kom tsis txhob muaj re-paug thiab oxidation ntawm qhov chaw.
4. Tom qab siv lub laser kom plam cov av, ntxuav nws nrog uas tsis yog-corrosive tshuaj txoj kev.
Feem ntau yog cov thawj peb txoj kev. Qhov thib plaub txoj kev yog xwb nyob rau hauv cov tu ntawm pob zeb artifacts.
Internationally, laser cleaning technology has been applied to stone materials for more than a decade. Since the investment in laser equipment is still relatively expensive, it is still difficult to generalize the application. However, laser cleaning technology has the advantages that traditional cleaning methods can't match. With the continuous improvement of technology and mass production of equipment, laser cleaning technology will play an important role in the cleaning of stone materials.
