The importance of cultural relic restoration is self-evident. For this reason, many workers in this field have been seeking more efficient restoration tools. In recent years, laser cleaning machines have attracted their wide attention with their unique advantages. They have set their sights on this new type of equipment, hoping to include it in their tool library for cultural relic restoration. However, there are many types of laser cleaning machines on the market, and how to choose the equipment suitable for cultural relic restoration has become a problem they face.
As a laser enterprise integrating production and sales, Legent-laser is well aware of customer needs. The laser cleaning machines we provide cover two main types: pulse laser cleaning machines and continuous laser cleaning machines. These two cleaning machines have their own advantages in cultural relics restoration. Whether you choose which one to use by yourself or get advice from professionals, you need to understand the advantages and disadvantages of these two types of laser cleaning machines.
Pulse laser cleaning machine
The advantages of pulse laser are:
- Short action time, less thermal damage to cultural relics;
- High pulse energy, can remove more stubborn dirt;
- Adjustable pulse width, can adapt to the cleaning of cultural relics of different materials.
The disadvantages of pulse laser are:
- Slow cleaning speed;
- High equipment cost.
CW laser cleaning machine
The advantages of continuous laser are:
- Fast cleaning speed;
- Low equipment cost.
The disadvantages of continuous laser are:
- Long action time, greater thermal damage to cultural relics;
- Low pulse energy, difficult to remove more stubborn dirt.
Generally speaking, for cultural relics with brittle materials and complex surface structures, it is more appropriate to use a pulse laser cleaning machine; for cultural relics with harder materials and lighter surface contamination, a continuous laser cleaning machine can be used.
suggestions we offer
According to the usage characteristics of the two laser cleaning machines, the following are some specific usage suggestions:
For fragile cultural relics such as paper cultural relics and silk cultural relics, pulse laser cleaning machines should be preferred.
For harder cultural relics such as metal cultural relics and ceramic cultural relics, pulse laser cleaning machines or continuous laser cleaning machines can be used.
For cultural relics with painted and decorated surfaces, pulse laser cleaning machines should be used, and attention should be paid to controlling laser parameters to avoid damage to painted and decorated surfaces.
For cultural relics with inscriptions, the inscriptions should be protected before cleaning to avoid damage to the inscriptions by laser irradiation.
The application of laser cleaning machine is not simple. Before using laser cleaning machine to repair cultural relics, cultural relic restoration experts should conduct comprehensive and detailed inspection of cultural relics, evaluate the material, state and pollution degree of cultural relics, and select appropriate laser parameters according to the specific situation of cultural relics. Legent-laser not only supports customized production, but also has a dedicated technical team to provide customers with laser cleaning machine selection guidance and free cleaning tests.
