传统古法与现代机制宣纸耐久性对比研究

Comparison Study on Permanency for Traditional Handmade Xuan Paper and Modern Mechanical Xuan Paper

利用QUV/SPRAY型紫外光照老化仪对传统古法和现代机制宣纸进行耐久性试验,并测试和对比老化前后两类宣纸的机械强度及颜色变化。研究结果表明:随着光照老化时间的延长,两类宣纸的机械强度下降明显,但古法宣纸的机械强度始终大于机制宣纸;从颜色变化来看,当光照老化时间小于160h时,两类宣纸的颜色变化不大,而随着光照老化时间的延长,机制宣纸的颜色比古法宣纸更稳定。

Compression measurements were employed to measure the mechanic strength and the color difference of Xuan paper after artificial accelerated illumination ageing test. As the extension of artificial accelerated illumination ageing time,the mechanic strength was reductive obviously for two types of Xuan paper,but the handmade Xuan paper was always more mechanic strength than the mechanical one. From the change in color,the artificial accelerated illumination ageing was less than 160 h, the color change for two types of Xuan paper changed rarely; while the mechanical Xuan paper was even more stable than the handmade Xuan paper with the illumination ageing longer time.
