Abstract
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.
