几种楮皮纸的润墨性能研究

Study on the Ink Moistening Properties of the Paper

手工楮皮纸在中国的应用十分广泛,在古籍的复制、保护与修复、书画创作、书画装裱等方面有着重要的使用价值。本文选取了三种不同定量、匀度较好的楮皮纸,测定了每种纸张的定量、白度、耐折度、紧度及抗张强度等重要性能参数,比较厚度不同的楮皮纸性能变化。通过测定墨迹扩散形状以及接触角实验,比较其润墨性能差异。结果表明:(1)纸张的定量与厚度不是简单的正比关系,纸张的定量、厚度以及紧度综合影响纸张的强度性能以及光学性能。(2)三种样品的润湿性能总体来说都趋向于被浸润状态,水滴在接触到纸面时瞬间被吸收,润湿性能都较为良好。润墨性能在墨汁为原浓度时,墨迹扩散较小,边缘层次清晰。而浓度配比后,润墨性能变化更趋近于其润湿性能,墨迹扩散较快,面积有明显增加,边缘呈锯齿状。

The paper is widely used in China.It has important value in the reproduction,protection and restoration of ancient books,the creation of calligraphy and painting,and the mounting of calligraphy and painting.In this paper,three kinds of paper with different quantitative and uniformity were selected.The quantitative,whiteness,folding resistance,tightness,tensile strength and other important performance parameters of each paper were measured,and the performance changes of different thickness of paper were compared.By measuring the diffusion shape and contact angle of ink,the difference of ink moistening performance was compared.The results show that:(1)with the increase of paper weight,the paper thickness does not necessarily increase,but also related to the fiber density.(2)The wettability of the three samples tends to be wetted in general.The water droplets are absorbed instantly when they contact the paper surface,and the wettability is good.When the ink concentration is the original,the ink diffusion is small and the edge layer is clear.However,after the concentration ratio,the ink moistening performance is more similar to its moistening performance,ink diffusion is faster,the area is significantly increased,and the edge is zigzag.
