“醋综合症”监测用气敏测试纸的研制

Gas-Sensitive Testing Paper for Monitoring Acetic-Acid Syndrome

醋酸纤维胶片因水解而衰变的问题，是影像保存部门的一个重大技术难题。为了解决影片档案现场监测的需要．研究成功了一种用酸碱指示剂澳甲酚绿（文中简称XJFL）制成的气敏测纸，取得了很好效果。此方法简便、实用、且费用低廉。本文对此项研究作了扼要的介绍。

Degradation of cellulose triacetate film caused by hydrolysis is a delicate problem in the preservation of archive films. Aimed at monitoring in-situ the environment of films storage, the authors achieved to prepare a new gas-sensitive testing paper made with the acid-alcali indicator brom-cresol-green, showing satis factory results, thus presenting an useful, handy and non-expensive device. This paper outlines this research work.
