摘要

作为纤维素降解分析的基础研究，在用氙灯和紫外线照射的纤维素片上进行了通过ATR法的TG测量和FT-IR测量，并将结果与乙酸纤维素片进行了比较。在热分解开始温度下，类纤维素表现出降低，乙酸纤维素表现出增加。从热解开始温度和表面的IR光谱获得关于样品表面的劣化的信息，并且从DTG的峰值温度获得关于样品内部的劣化信息。将结果应用于保存的实际样本。每个赛璐珞样品被光降解，并且降解程度被认为与当用氙灯照射0.2mm厚的片材8小时时的变化相似。通过设计测量条件，证实TG/DTA测量和赛璐珞样品是有效的测量方法。

Degradation Analysis of Celluloid

As a basic study of the degradation analysis of celluloid, TG measurement and FT-IR measurement by the ATR method were performed on a celluloid sheet irradiated with a xenon lamp and ultraviolet rays, and the results were compared with the cellulose acetate sheet. Celluloid showed a decrease in the thermal decomposition start temperature, and cellulose acetate showed an increase. Information on the deterioration of the sample surface was obtained from the pyrolysis start temperature and the IR spectrum of the surface, and information on the deterioration inside the sample was obtained from the peak temperature of DTG. The results were applied to the actual sample saved. Each celluloid sample was degraded by light, and the degree of degradation was considered to be similar to the change when a 0.2 mm thick sheet was irradiated with a xenon lamp for 8 hours. By devising the measurement conditions, it was confirmed that TG/DTA measurement and celluloid sample are effective measurement methods.
