摘要:本研究探讨了6种纸质文献的表面自由能(简称表面能)测试方法,以Zisman法的测量值为基准,比较了Neumann法、ZDY法、HM法、OWRK法、OCG法,选取更简便且理论数据与实际测量值相符合的测量方法。结果表明,Zisman法所得纸张表面能为26.24 mJ/m2,纸张施胶后表面能转低,难润湿;Neumann法的测量结果较好,且能最大程度简化表面能的测试步骤,在大规模脱酸处理中能提高古籍的修复效率,并能减少对纸张的损害。ZDY法的实际测量值和理论数据差距较大,不适合用于测量纸张表面能。HM法选择二碘甲烷和丙三醇作为检测液体时,所得偏差较小。OWRK法、OCG法需选择适当的检测液减小标准偏差,若检测液选择不当,会得出与实际不符的结论。 |
Abstract:In this paper, the six surface free energy(called surface energy) testing methods of paper literatures were studied. Based on the measured data of surface energy testing method by Zisman, other methods of Neumann, ZDY, HM, OWRK, and OCG were compared to obtain more convenient surface energy testing method of paper literatures with more consistent between theoretical data and measured data. The results showed that the surface energy measured by Zisman method was 26.24 mJ/m2. The surface energy would transform into a low value after sizing, and paper was difficult to wet. The results obtained by the Neumann method for measuring the surface energy of paper were relatively reliable, and the Neumann method could simplify the surface energy test to the greatest extent. In large-scale deacidification treatment, the Neumann method could improve the restoration efficiency of antique books and reduce damage to paper. The ZDY method was not suitable for measuring the surface energy of paper because of the large difference between measured data and theoretical data. The HM method gave a low deviation when diiodomethane and propanetriol were chosen as the testing fluids. The OWRK method and OCG method required the selection of appropriate testing fluids to reduce the standard deviation, and if the testing fluids were not selected correctly, conclusions might be drawn that do not correspond to reality. |
