电影胶片划痕修复研究

Restoration Research on Scratched Cine-film

电影胶片是重要的历史文化遗产之一,也是档案保护工作的重要组成部分。在保存和使用过程中,电影胶片易发生划伤现象,严重影响电影胶片记载的图像效果。陕西师范大学历史文化遗产保护教育部工程研究中心研制开发出了以水性氟材料为主,添加适量的纳米二氧化硅和水性聚氨酯改性的电影胶片划痕修复液。该修复液可以有效地修复划伤电影胶片,消除划痕对电影胶片画面的影响,并具有环保、无污染等特点。使用该修复液修复划伤电影胶片,不仅可以提高电影胶片的机械强度,还可以增强胶片的耐久性,有利于胶片的长期保存。

The cine film is an important historical and cultural heritage,as well as an important part of the archives protection work.In the process of use and preservation,the cine film is vulnerable to scratch,which seriously influences the effects of recorded images.The Engineering Research Center of Historical and Cultural Heritage Protection,Ministry of Education in Shaanxi Normal University has developed a restoration solution for cine film scratch,which is mainly made of water soluble fluorine material,with nano-silica and water soluble polyurethane as additives.The restoration solution can effectively repair the scratched cine film and eliminate the scratch effects on images,behaving eco friendly and pollution free.In use of this restoration liquid,the mechanical strength and the durability of the film have been enhanced,which contributes to a long-term preservation for the cine film.
