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Al~(3+)是导致纸张酸化,引起纸张性能发生变化的主要原因之一。
Ancient calligraphy and painting, rare books and other ancient paper-type artifacts of ancient civilizations in China is one of the products is an important class of historical and cultural heritage. Studies have shown that acidification is one of the major diseases that affect the durable preservation of paper artifacts. Alum and gelatin formulated mortar alum water in ancient China cooked rice paper production, traditional painting and other mounting applications, play a significant role in preventing pigment diffusion. Studies have shown that the use of glue alum water is one of the important reasons for the acidification of paper artifacts. After testing the alum aqueous solution and potassium sulfate aqueous solution on the paper, the change of acidity, tensile strength, folding resistance and whiteness of the paper were tested. It was confirmed that Al 3+ in the alum water caused the paper acidification, One of the main reasons why paper performance changes.
