摘要
醋酸胶片齿孔收缩是胶片保存过程中普遍发生的一种现象,然而对其收缩机理的研究至今没有开展过。本文选择不同温度、湿度作用于正常醋酸胶片和齿孔收缩的胶片,观察胶片齿孔距的变化,分析温度湿度对胶片长度变化的影响。实验研究得出,胶片长期保存在干燥的环境中,会发生程度不同的收缩;高湿对齿孔收缩胶片有一定的恢复作用,湿度越大,恢复程度越高;胶片长度在恢复期间,开始处理时,伸长效果明显,并非出现随着时间延长,胶片不断伸长的现象。本研究在醋酸胶片齿孔收缩的原因方面做了初步探索,对变形胶片的恢复有一定参考作用。
The shrinkage of acetate films is often take place during storage.however why this happens easily is not clearly.This article discusses that temperature and humidity of storage effects on acetate films,the result is that acetate film is kept in low humidity for long time,shrinkage will take place.The researchers analyzed the situation that the lengths of different kinds of acetate film had changed with different treatment and tried to find some pattern which could explain how the length of film changed.The researchers try to find a way to recover the shrinkage film through high humidity.Recovering affection is clearly at beginning of high humidity treatment.but it has no more recover affection as treatment time increasing.From this research,we get some knowledge about recovering of shrinkage film.
