| 摘要:针对纸质文物保存中的霉菌病害问题,将分离出的7种霉菌,分别接种于宣纸上进行培养,通过测定霉菌生长后纸张样品的α-纤维素含量、木素含量、羧基含量和聚合度,并与空白样品进行比较。实验结果表明，7种霉菌均降低了纸张的纤维素含量和聚合度,木素和羧基含量均增加。通过上述测试,可以定量衡量霉菌对纸张化学成分的影响,破坏纸张内部结构,降低纸张寿命。由此可见,在纸质文物保存过程中,做好防霉工作显得尤为重要。 |
| Abstract:According to the mould diseases of paper relics, seven kinds of mold were reparated and respectively inoculated on Xuan Paper, then the papers were characterized by means of measuring cellulose content, lignin content, carboxyl content, polymerization degree of paper samples after the growth of the molds, and compared with the blank paper samples. The results suggested that the seven kinds of mold all decreased the polymerization degree and cellulose content, and increased the lignin and carboxyl contents of the paper. The impact of mold on chemical composition of the paper was quantitatively measured, the internal structure of the paper was decomposed, the life of the paper was reduced. Obviously mildewproof is very important in paper relics preservation process. |
