【摘要】：采用环境模拟实验舱法探究了在微环境中乙酸气体对生宣、熟宣、信纸和A4纸耐久性及档案字迹的影响。结果表明,乙酸气体对纸张的物理强度、酸度、白度和字迹均有一定程度的负面影响。通过使用扫描电镜(SEM)和X射线荧光光谱(XRF)进一步分析探讨了乙酸气体对纸张作用的机理,研究发现乙酸气体会使纸张中的填料发生团聚,降低纸张的聚合度和结晶度。
[Abstract]:The effects of acetic acid gas on the durability and archival handwriting of paper in microenvironment were investigated by means of environmental simulation. The results showed that the physical strength and acidity of the paper were affected by acetic acid gas. Both whiteness and handwriting have some negative effects. The mechanism of acetic acid gas acting on paper is further analyzed by using SEM and XRF. It is found that acetic acid gas can agglomerate the fillers in paper. Reduce the degree of polymerization and crystallinity of paper.
