摘要:本实验分析了西藏雪拉藏纸、四川德格藏纸、囊谦嘎玛藏纸和囊谦黑色藏纸等4种藏纸的抗老化性能的差异性。分别对4种藏纸进行了紫外光老化前后纸张白度、耐折度、抗张力等指标的检测。结果表明,4种藏纸老化前各项指标相差较大,老化后上述指标均呈现下降趋势,西藏雪拉藏纸和四川德格藏纸的白度、耐折度、抗张力保留率好,具有相对良好的抗老化性。
Abstract:This study analyzed the difference of anti-aging performance of four kinds of Tibetan paper, namely Tibetan Xuela Tibetan paper, Sichuan Dege Tibetan paper, Nangqian Gama Tibetan paper and Nangqian black Tibetan paper. The whiteness, folding endurance and tensile strength of the papers were measured before and after ultraviolet aging. The results showed that the properties of the four kinds of Tibetan paper before aging were quite different, however, the above properties showed a downward trend after aging. Tibetan Xuela Tibetan paper and Sichuan Dege Tibetan paper had good whiteness, folding endurance, retention rate of tensile strength and durability.
