我国每年都要生产大量的各种类型的感光胶片。制作胶片感光层的基质——明胶,由于含氮量高,可被多种霉菌分解利用,在适合的温、湿度条件下,霉菌迅速生长繁殖,使胶片感光层出现各种毒菌斑点,轻则影响胶片的感光性,重则造成感光膜脱落,胶片变形以至完全报废。因此,在制作胶片过程中要加入适量的防毒剂,以保证胶片性能稳定。
Every year, our country produces a large number of various types of photographic films. Production of film photosensitive layer of the substrate - gelatin, due to high nitrogen content, can be a variety of mold decomposition and utilization, under the conditions of suitable temperature and humidity, mold rapid growth and reproduction, the film photosensitive layer of various toxin spots, light It will affect the sensitivity of the film, it will cause the photosensitive film off, the film deformation and even completely scrapped. Therefore, in the production process of the film to be adding an appropriate amount of anti-virus agent to ensure film performance and stability.
