利用人工老化实验的方法,将涤纶胶片单独老化及与醋酸片一起进行老化处理,通过实验前后的各项性能的对比,来推断已产生醋酸综合症的醋酸胶片对涤纶胶片的影响。实验结果从定性定量的角度,充分证明了醋酸胶片会对与其长期共同保存的涤纶胶片产生影响,从而提出不同种类缩微胶片应隔离保存的建议,为缩微胶片的保存实践提供支持。 Using the method of artificial aging experiment, the aging of the polyester film alone and the aging of the acetic acid film were performed. The comparison of the performance before and after the experiment was conducted to infer the influence of acetic acid film which has produced acetic acid syndrome on the polyester film. Experimental results from the qualitative and quantitative point of view, it is fully proved that acetate film will be its long-term co-preservation of polyester film have an impact, which proposed different types of microfilm should be kept isolated recommendations for microfilm preservation practice.
