摘要:
作为重要的历史文化遗产——电影胶片,其基材醋酸纤维素酯在长期保存过程中易发生醋酸综合症,严重影响了其耐久收藏。对醋酸纤维素酯电影胶片片基发生醋酸综合症前、后的物理化学性能进行了对比研究,在通常情况下,醋酸纤维素酯电影胶片在保存过程中易发生醋酸综合症,表现为胶片的极性增大,亲水性增强,热稳定性降低,表明低温低湿条件有利于延缓醋酸综合症的发生。因此,对于醋酸纤维素酯电影胶片,特别是已发生醋酸综合症的电影胶片,应在低温低湿条件下保存。

Abstract:
The cine film is an important historical and cultural heritage.The substrate of the cine film,i.e., cellulose acetate, easily suffered from the acetic acid syndrome in the long-term preservation, which seriously affects its durable collection.The physical and chemical properties of cellulose acetate film substrate with and without acetic acid syndrome were comparatively studied. The results showed that,in general, the acetic acid syndrome happened easily during the preservation, and the polarity and hydrophily of the film was increased, while the thermal stability was reduced. The experimental results indicate that the cellulose acetate film, especially with the acetic acid syndrome, should be stored in the surrounding of lower temperature and humidity.
KeyWords:
