摘要
为分析元时期纸质文物中木质素含量与纸张老化之间的关系,以元时期纸质文物碎纸及几种专门修复元时期纸质文物的纸为研究对象,提出了一种系统性的纸张木质素含量测定方法,再通过纸张抗氧化性能分析,得到木质素含量与纸张老化之间的关系。结果表明:木质素的存在会导致纸张酸性提升,在长时间保存时容易导致纸张变黄、变脆,加速纸张的降解;木质素的含量越高,这种负面影响效果越显著。
In order to analyze the relationship between lignin content and paper aging in paper cultural relics of the Yuan period,a systematic method for the determination of paper lignin content was proposed based on paper fragments of paper cultural relics of the Yuan period and several paper specially repaired paper cultural relics of the Yuan period,and the relationship between lignin content and paper aging was obtained through the analysis of paper antioxidant properties.The results showed that:The presence of lignin will lead to increased acidity of paper,which is easy to lead to yellow and brittle paper when stored for a long time,and accelerate the degradation of paper.The higher the lignin content,the more significant this negative effect is.
