摘要
空气中的SO_2气体对丝织品文物有一定的危害作用。课题分别试验了各种丝织品试样在50μmol/mol的SO_2气体下不同时间的影响变化。通过色差分析,红外分析,氨基酸分析及XRD分析对丝织品进行表征,得到了40℃下50天的干热老化丝织品试样在50μmol/mol的SO_2气体下,随着试验时间的延长,其色差变化最大。经SO_2气体处理的丝织品试样的氨基酸成分发生改变,结晶度也变大,老化程度加大。本研究结果可为保存和保护丝织品文物提供依据。
SO2 gas in the air has harmful effects on silk fabrics relics. In this study various silk fabrics samples were tested in 50μmol/mol of SO2 gas in air for various periods of time. Analytical techniques include chromatic aberration analysis, infrared analysis, amino acid analysis and x- ray diffraction （XRD） were usedto characterize the samples. The silk fabric sample underwent dry heat aging on 40℃ for 50 days. It is concluded that the greatest change happens as the time increases ： both the amino acids and the crystallinity of the silk fabric sample change in the presence of SO2 as the degree of aging increased.
