Research Of The Preservation Status And Protection Countermeasures Of Metal Cultural Relics In Fangchenggang Museum

China is an ancient country with a rich culture and a long history.The cultural relics is large in quantity.Due to the unique historical background of cultural relics,its value is not only reflected in the economy,but also the most important is its value in history,art and scientific research.Cultural relics are the memory of the nation and are non-renewable resources.At present,countries around the world are paying more and more attention to the protection and use of cultural relics.Metal cultural relic is the precious wealth in the process of human social development.As part of the cultural heritage,the concept of preventive protection has also become increasingly popular.Therefore,the research on the protection of cultural relics in the collection has become a key research area for cultural relics protection in various countries around the world.In this work,we study that present situation and countermeasures of metal cultural relics in museum in Fangchenggang,and carry out relevant investigation.The study mainly analyzes the factors that have important influence on temperature,relative humidity,and photochemical reaction to the collection of metal cultural relics,and compares it with the impact of climate in Dalian on collections of metal cultural relics in order to find out the coastal cities in the north and south of China.The climate has different influences on the collection of metal relics in the collection,and measures for protection are proposed according to local conditions.The study used metallographic microscopy and scanning electron microscopy spectrometry to perform some scientific and technological analysis onsome of the metal relics of the Fangchenggang Museum,and combined with the research results of the iron cannon in the Beihai City Collection to reveal the degree of completeness and corrosion of the artifacts,corrosion mechanism,metal composition,metallurgical structure,casting process and other information.On the one hand,scientific and technological analysis provides a comprehensive understanding of the components,materials,structures and damage conditions of the objects to be repaired,and put forward scientific research countermeasures to provide technical support and scientific guidance for the further implementation of the protection of cultural relics and the environment,as well as a reference and reference basis for similar cultural relics protection.On the other hand,it can leave important scientific data and information for further study of its historical,artistic,scientific,and cultural values.
