摘要:

醋酸纤维素酯胶片档案保存环境的温湿度是影响胶片长期保存的关键因素之一。由于技术及理念等方面原因,使得我国大部分档案馆的保存环境均未达到国际标准组织所推荐的条件,致使这些宝贵的胶片档案正在遭受醋酸综合症的危害。本文选取20世纪80年代国产的醋酸纤维素酯胶片作为研究对象,研究了接近实际馆藏温度和湿度对胶片片基层和乳剂层的影响。结果表明:当胶片档案保存的实际温度高于20℃、湿度高于60% RH时,均会对胶片的乳剂层和片基层造成不同程度的损伤,特别是高湿条件会严重损毁胶片乳剂层所载信息。本研究对胶片档案的保存具有一定的参考意义。

Abstract:

The storage temperature and humidity of the cellulose acetate film file serve as the key factors affecting the long-term preservation of the film. The valuable film files are suffering the harm of acetic acid syndrome in most archives in China because the technology and concept of the preservation film files do not achieve the ideal preservation condition that is recommended by the international standard organization. In the present study, the cellulose acetate film, which is made in China in the 1980s, is selected to serve as experimental sample and to study the effect of actual temperature and humidity on the film base and emulsion layer. The results show that the film base and emulsion layer cause varying degrees of damage when the actual temperature is higher than 20℃ and the relative humidity is higher than 60%. Moreover, the contained information of film emulsion layer is seriously damaged at the condition of high humidity. This work will provide some guidance for the preservation of film archives.

Key words: cellulose acetate film, preservation temperature and humidity, degradation, strength
