由三醋酸纤维和亲水的明胶感光层组成的电影胶片是各种微生物生长的良好培养基。微生物能在较宽的环境温度、湿度和酸碱度范围内生长。这个性能造成电影胶片在贮存过程中经常有被微生物损伤和毁坏的潜在危险,特别是在周围环境高温高湿的条件下。即使是在符合于推荐技术标准PTM19—87—80《电影胶片、早期电影胶片在专门国家电影档案馆里长期保存的条件》所建议的规定条件下(空气相对湿度为40—50％,温度不高于15
Cinema film consisting of triacetate fiber and hydrophilic gelatin photosensitive layer is a good medium for the growth of various microorganisms. Microbes can grow over a wide range of ambient temperatures, humidity and pH. This property has the potential to cause the film to be damaged and destroyed by microorganisms during storage, especially under conditions of high temperature and humidity in the surrounding area. Even under the conditions recommended by PTM 19-87-80, “Conditions for Long-Term Preservation of Early Motion Picture Films in Special National Film Archives” (air relative humidity 40-50%, temperature not Above 15
