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。
Filmstrip is one of the important historical and cultural heritage and an important part of the file protection work. In the process of preservation and use, the film is easy to scratch the film, seriously affecting the movie film recorded image effects. Shaanxi Normal University historical and cultural heritage protection of the Ministry of Education Engineering Research Center developed a water-based fluorine-based materials, adding an appropriate amount of nano-silica and water-based polyurethane modified film scratch repair fluid. The repairing liquid can effectively repair the scratched film and eliminate the influence of scratches on the film screen, and is environment-friendly and pollution-free. The use of the repair fluid to repair scratched film, not only can improve the mechanical strength of the film, you can also enhance the durability of the film is conducive to the long-term preservation of the film.
