中文摘要:

      为了对比生宣纸和半熟宣纸在长期放置后的性能变化，对它们进行干热老化处理并观察干热老化前后的表面微观形貌和磨损三维形貌，分析并测定了干热老化前后这两种宣纸在不同浓度墨水配比下的静态接触角、吸附性、力学性能、耐磨性能，以研究2种宣纸在干热老化前后的性能变化。结果表明，干热老化前后生宣纸对淡墨水的吸附性均比其对浓墨水的好，未干热老化的半熟宣纸更易吸附淡墨水，而干热老化后则更易吸附浓墨水；干热老化后生宣纸的吸附性比干热老化前差，干热老化后半熟宣纸的吸附性比干热老化前好；干热老化后2种宣纸的力学性能较干热老化前均有所提高；干热老化前的生宣纸比干热老化后的更耐磨，而干热老化后的半熟宣纸比干热老化前的更耐磨。

Abstract:

      In order to compare the performance changes of different kinds of Xuan paper after long-term storage， dry heat aging test was carried out on raw and sized Xuan paper to study the changes of surface micro morphology and wear three-dimensional morphology. The static contact angles， adsorbabilities， mechanical properties， and wearabilities of the two Xuan papers before and after dry heat aging were tested and compared. The results showed that before and after dry heat aging， raw Xuan paper had a better adsorption of light ink compared with thick ink； the sized Xuan paper tended to absorb light ink before dry heat aging while after dry heat aging， it preferred to absorb thick ink. The absorbality of raw Xuan paper after dry heat aging was lower than that of before while the sized Xuan paper showed opposite trend， however， mechanical propertied of both Xuan papers increased after dry heat aging. In terms of wearability， raw Xuan paper exhibited reduction after dry heat aging while sized Xuan paper turned out to be more wear-resisting.
