Science & Technology Analysis And Protection Restoration On The Sample Of Da Qing Bao Chao

As the forerunner of "banknote",Da qing bao chao not only has the merit of being lighter than metal money,but also can promote the rapid development of commodity economy,adjust and integrate the capital,and has an indelible position in economic development.The treasures of the Qing Dynasty survived more,but with the passage of time,inevitably appeared a variety of damage.Due to the irreplaceability of such important cultural relics,their protection,cultural heritage and functional rejuvenation have become the key issues in the restoration of modern cultural relics.Based on the previous studies,this dissertation starts from the literature review,on-the-spot investigation and experimental analysis,and makes a detailed analysis of the history of Da qing bao chao,and makes a scientific and technological analysis of its printed materials and technologies.Based on this,On the discussion of the method of restoration of the Qing treasure,for the study of paper remediation provides a new idea.Through the scientific analysis of Da qing bao chao printing materials and technics,this paper analyzed the microscopic morphology,material composition analysis and production process of Da qing bao chao.The results showed that: the Treasure notes using hemp paper,above red cinnabar,blue pigment Prussian blue,black pigment is carbon black.At the same time,it elaborates the related concepts of restoration of cultural relics;analyzes the theories and examples of restoration,inheritance and rejuvenation of urban cultural relics in developed countries in Europe and the United States;analyzes and summarizes the current policies and regulations,status and success stories in our country for relic protection and restoration Predecessors' methods and techniques of repairing paper artifacts.And on this basis,to explore the restoration of the treasures of Qing Dynasty.Using scientific and technological analysis of the data to find out the similarities and differences with the Da qing bao chao paper fiber raw materials,and their self-made paper after the color,gloss,texture and other aspects of the comparison,the final experiment through the production of paper close to the Da qing bao chao notes.It provided reference data for the research of Daqing bao chao in the future and provided new ideas and methods for the repair of paper.
