摘要
几种不同型号的印刷胶片以温度50℃、相对湿度80%的条件进行1—4天的人工老化试验,所得的结果与自然保存1至2年的同样胶片性能进行分析比较。自然保存是在有空调和无空调两种环境条件下进行的,前者是温度21℃±3℃,相对湿度50%—65%;后者是当地的自然条件,冬天最低为-8℃,夏天最高达40℃,湿度变化范围更大。本文对此进行详细阐述。
Several types of graphic arts films were undergone artificial ageing tests,been kept in an housing of 50℃ temperature and 80% relative humidity for 1-4 days,the resulted data were compared with those stored in either normal warehouse or air-conditioned storage room for 1-2 years.The said air-conditioned has a temperature of 21℃±3℃ and 50%-65% relative humidity;the normal warehouse is as the local weather with a lowest temperature of -8℃ in the winter and a highest ones of 40℃ during the summer,the humidity range is rather larger.This paper offers a detailed report of this study.
