Our country is one of the earliest developed countries in the world. A large number of cultural relics unearthed, such as bronze, red bronze, iron and other precious metal utensils unearthed, if you do not take effective protective measures, will suffer from the erosion of harmful substances in the atmosphere, loss of its historical prototype, reduce life expectancy, resulting in irreparable Loss. Metal artifacts, mainly ancient bronzes and ironwork. When they were collected in the museum, the corrosion they suffered was mainly atmospheric corrosion. For copper, copper and air were the major contributors. CO_2 and H_S generated Cu2 (OH) 2Co3 and CuS.
