【摘要】 古旧字画、古籍善本等纸质类文物是我国古代文明的产物之一,是一类重要的历史文化遗产。研究表明,酸化是影响纸质文物耐久保存的主要病害现象之一。明矾与明胶配制而成的胶矾水在我国古代熟宣纸生产,字画传统装裱等方面应用广泛,起到防止颜料扩散的重要作用。研究表明,胶矾水的使用是导致纸质文物酸化的重要原因之一。本文通过测试明矾水溶液、硫酸钾水溶液涂布于纸张后,测试纸张酸度、抗张强度、耐折度、白度等变化,证实了胶矾水中的Al³⁺是导致纸张酸化,引起纸张性能发生变化的主要原因之一。更多还原

【Abstract】 Paper historical relics,such as antique calligraphy and painting,ancient rare books,etc.is one of the product of Chinese ancient civilization,is a kind of important historical and cultural heritage.Research shows that the acidification is one of the major diseases that affect the durable preservation of paper historical relics.The solution composed of alum and gelatin was widely used in manufacturing Shu Xuan in ancient China,mounting traditional calligraphy and painting,etc.which also has an important effect on preventing the pigments spreading.While,gelatin alum solution is one of the important causes leading paper historical relics acidification.This paper researches on the acidity,tensile strength,folding strength,whiteness change of the paper which is coated gelatin alum solution and K₂SO₄ solution.The results verify that Al³⁺ in gelatin alum solution is one of the major reasons leading paper acidification and causing the properties changing.更多还原
