The museum shows us the majesty of history, the heritage of culture and the charm of art. Collection is the carrier of history, culture, and art information transmission. However, the quality of collections is affected by environmental climate, air pollution, light radiation, insect harm, microbial reproduction and other environmental factors.
The temperature and humidity of the cultural relic library is the main factor affecting the state of the cultural relics. 1. As a metal collection rust, the common bronze disease is caused by the humid storage environment.
2. Reduce the durability of paper cultural relics, leading to cellulose hydrolysis, bloating, exacerbating dust destructive power, shortening the preservation period. 3.
As a result, the handwriting fades, and the cultural relics lose the original use value. 4, leading to moldy mold, damaging mold damage in the cultural relics and warehouses. 5, humidity leads to deformation or cracking of collections such as wood, paper, and silk products.
High humidity causes deformation, dryness causes cracking. The humidity of metal cultural relics should be between 45%and 50%, paper and textiles are controlled between 50%and 55%, and the warehouse warehouses of wood lacquerware are controlled between 60%and 65%. However, considering the characteristics of different collections, the relative temperature of the museum is generally controlled between 15 ¡ã C and 25 ¡ã C, and the humidity is controlled between 45%and 65%.
A slight change in this value will not affect the cultural relics, which will not affect the impact on cultural relic.
