However, the sulfate-reducing bacteria of the bronze surface is very smooth, the sulfate-reducing bacteria formed on the surface of a black FeS corrosion layer in bronze. Currently, sales of the bronze in the tourism are far from ideal. The rust layer in anaerobic or anoxic long-term underground role, the lattice will rearrange to form a dense, stable black protective film, but to protect the bronze to prevent further corrosion. Atmospheric corrosion of bronze ware unearthed in the display, or treasury. When the relative humidity <60%, mainly by chemical reaction, electrochemical reaction almost does not occur, the atmospheric corrosion rate of the slowest, joint action when the relative humidity above 65%, the electrochemical reaction and chemical reaction, the atmospheric corrosion rate will produce a peak.
When the relative humidity close to 100% water vapor in the air will form a layer thickness of the surface of the Bronze> 1μ of the water film, the formation of the water film effectively prevent the diffusion of oxygen, so that electrochemical corrosion in plain corrosion, so that the atmospheric corrosion rate to boundary between the former two. Thus, control of atmospheric corrosion control the museum environment. Its ration accounting for the entire income of tourism industry is relatively low which is because that the designing and the market development of the tourism bronze is less than ideal. Seawater corrosion in general rarely occur in the Field Archaeology and Museum. But before the underwater archaeological relics water main corrosion.
Can be seen through the corrosion on the bronze, the bronze is very prone to corrosion. Especially the recently unearthed bronze, if not immediately get some protection, it will soon be further rust corrosion. Therefore, the heritage site protection more and more workers the importance of heritage conservation. Down to talk about the bronze-site protection. The recently unearthed bronze, the first should be an immediate mandatory dry, so that the bronze itself completely dehydration. There are a lot of problems and shortcomings about the bronze. Theoretically should be taken to the oven temperature drying 2 hours at 105 ℃. Or temperature control with ultraviolet light at 105 ° C dry.
Bronzes, wood fiber and other attachments, the temperature should be appropriate to reduce and control the slowly dried to 40 ° C to 60 ° C). However, in practical work is generally not so operating. Should select the appropriate drying method according to the actual situation. If the weather is better the day, can be bronze direct sunlight in order to achieve the mandatory drying effect. Forced drying, bronze in basic, and then can be based on the actual situation on the objects for further processing. In this paper, from a vision of art and design workers, starting from the design and development of the tourism bronze, the author made some comments and suggestions on the design and development of tourism bronze.
