纸张加固材料的选择及应用毕业论文

 2020-06-19 22:17:06  

摘 要

按照我国纸张文物现在的实际情况,因此,研究我国纸张文物的修复加固迫在眉睫。由于纸质的酸化,老化,破损等各种各样的因素,本课题采用聚氧化乙烯、聚乙烯吡咯烷酮等高分子材料和羟乙基纤维素等纤维素类加固材料,通过大量反复试验,选择出最合适的加固材料,对处理前后纸张的各项理化性能进行测试表征,以评估此加固材料对纸张的保护效果,得到三种加固材料对于纸张加固各有各的特点。

Selection and Application of Reinforcing Material for Paper

ABSTRACT

According to the actual situation of China's paper relics, therefore, the study of China's paper relics repair and repair is imminent. Because of the various factors such as acidification, aging and breakage of paper, this paper adopts cellulose materials such as Polyethylene oxide and Polyvinyl pyrrolidone and cellulose-based reinforcement materials such as Hydroxyethyl cellulose.Through a large number of repeated tests, The physical and chemical properties of the paper before and after treatment were tested to evaluate the protective effect of the reinforcing material on the paper. Three kinds of reinforcement materials were obtained for the reinforcement of the paper.

Keywords: Paper artifacts;reinforcement measures;Polyethylene oxide;Hydroxyethyl cellulose;Polyvinyl pyrrolidone
