At present, the protection and restoration of bronze cultural relics are facing some major challenges. Laser cleaning technology is of great help to the non-destructive restoration and cleaning of bronze cultural relics, and has great research value and significance. As a new type of laser processing technology, laser cleaning technology can effectively remove surface stains and rust stains on the basis of protecting cultural relics. Compared with traditional cleaning technology, it has many advantages. This article mainly introduces the cleaning application of laser cleaning machine on bronze cultural relics.

As a new type of cleaning technology, laser cleaning has been widely used in various fields. It adopts the high-energy-intensive characteristics of laser beams. Under the premise of the same energy input, the beam can be collected into different diameters and different energy densities through the concentrating system. Light spot. Then through the difference of the energy difference of the light spot, only the surface layer is removed, and the cleaning material body is not damaged. Laser cleaning uses these characteristics to effectively remove contaminants.

Traditional cleaning methods include physical cleaning, chemical cleaning and ultrasonic cleaning. These old-fashioned cleaning methods have been greatly restricted under the current strict requirements of environmental protection and efficiency. Laser cleaning is a new type of cleaning technology, which has minimal environmental pollution, fast cleaning efficiency, and can achieve no damage to the material matrix. Once launched, it has been loved by many industry customers.

Laser cleaning has advantages that traditional cleaning equipment can't match in the protection and restoration of cultural relics:

1. Laser cleaning is a selective cleaning, which is selective to the cleaning material substrate and the layer to be cleaned. This technology can make the surface of the substrate intact. For different dirt on the surface of different substrates, the dirt can be selectively cleaned by setting the parameters of the laser without damaging the substrate.

2. The environmental protection of laser cleaning. The waste of laser cleaning is basically solid powder, small in size, easy to store and clean, and low environmental pollution, which can be regarded as an environmentally friendly cleaning process.

3. The laser beam adopts the irradiated cleaning method, as long as the place can be irradiated by the laser, it can be cleaned. By adjusting the size of the light spot, it can be finely cleaned in the range of 0.01mm.

4. Laser cleaning uses non-contact cleaning. The traditional method is often close-range operation, which has mechanical force on the surface of the cleaned object, which is easy to damage the surface of the object. The laser cleaning is a kind of non-contact processing, which can easily realize long-distance operation and can complete many cleaning tasks in harsh environments.

The above is the cleaning application of laser cleaning machine on bronze cultural relics. There have been successful applications of laser cleaning technology in bronze rust removal at home and abroad. As long as the actual rust condition of the bronze ware, suitable laser and laser process parameters are used to remove the rust. The effect is relatively ideal, and it will not cause damage to the bronze base. At the same time, a dense passivation and rust removal effect can be formed, and it will not cause damage to the bronze substrate.
