纸张老化过程的检测技术与纤维素降解演化方程的研究进展OA

Aging degradation is an irreversible natural phenomenon of paper,but also an important factor affecting the preservation of paper documents and identification of physical evidence.Lignocellulose,the main component of paper,plays a key role in the durability and aging process of paper.This paper introduces the chemical mechanism of lignocellulose in the aging process of paper,and systematically combs through the detection technology of microstructure in the aging process of paper in recent years,and deeply analyzes the aging process of paper by combining with machine learning and other cutting-edge fields.We also summarize a variety of kinetic models proposed in the field of cellulose aging and degradation research at home and abroad,and summarize the changing law of paper in the aging process and its impact on durability.It aims to elucidate the key progress in recent years based on the research of paper aging mechanism and law from the level of characterization technology and dynamics,and provide theoretical support and technical path for the aging assessment of paper documents and judicial exhibits.
