纸张厚度及收卷直径对书画类文物的影响

Impact of paper thickness and rolling diameter on Chinese paintings

书画类藏品在保管收藏的过程中经常会出现折痕、起层乃至于断裂,严重地影响了书画的收藏安全及观赏效果。因此,本工作运用物理学的方法,重点研究了纸张厚度、收卷直径与上述病害形成的机理及其规律之间的关系,对如何避免由于收卷直径引起的书画折痕、折断等现象进行了可行性方案探讨。研究结果表明,在收卷直径相同的情况下,收卷时出现折痕的几率与纸张的厚度成正比;而同样厚度的纸张,收卷直径与收卷时出现折痕的几率成反比。根据研究结果,提出了在画幅收藏时,将其装裱成压境,并采用大直径收卷的方式放置于画筒之内;在展览时,则可以安装于镜框内或通过安装"速配天地杆"的方式,迅速将压境作品变成一幅古色古香的挂轴这一行之有效的解决方案。

Calligraphy and painting collections in the process of preservation often have creases, layers and fractures, which seriously impact the safety and the aesthetics of the calligraphy scrolls and paintings. The effect of paper thickness and winding diameter on the type of damage mentioned above is discussed, based on the results of physical studies. Furthermore, avoidance of these damages was also investigated. The results show that with the same winding diameter, the thicker the paper, the more likely paper will crease; with the same paper thickness, the smaller the winding diameter, the more likely paper will crease. Therefore, when storing a painting or calligra- phy scroll, the best practice is to cover it with a protection layer and then to store it in a tube with large winding core. When displaying it the best practice is to install it by using a ＂Quick and Easy installation of the cylinder＂. By removing the protective layer quickly, the object can be transferred to a hanging scroll with its antique appearance.
