Extending the durability of old books by atomized deacidification and reinforcement treatments

Abstract

Old books suffer from aging and deterioration spurred by acidification, oxidation, and other factors. To preserve these important historical documents, it is important to implement deacidification and reinforcement methods to extend their durability. In this study, microdroplets of 75 g/L sodium hydroxide solution were atomized before being utilized to neutralize acidity in the paper. As well, styrene acrylic latex was diluted to 10 times for atomization to function as a reinforcing agent. In addition to studying these methods individually, the effects of simultaneous deacidification and reinforcement were also studied.

Preservation Practices for Information Resources in Public University Libraries in Tanzania

“…Depending on the nature of the writing medium and the strength of the paper, less dangerous and more affordable methods of deacidification include the use of spray deacidification, ammonia gas deacidification, and aqueous deacidification (solution of calcium hydroxide and calcium bicarbonate) (Chattopadhyay 2007). Although this approach was not highly recommended by respondents in this study, Fan et al (2020) reported that it is important to implement deacidification and reinforcement methods to extend the durability of library information resources on paper.…”

Research on Strengthening Fragile Paper with Polyvinylamine

“…Owing to their molecular structure and properties that are similar to paper, they have emerged as a significant research direction for paper literature restoration. Organic compounds such as polyurethane, latex, acrylamide [ 12 ], and amino silane coupling agents [ 13 , 14 ] constitute synthetic polymer compounds. They mainly bind to hydroxyl groups in cellulose through crosslinking or chemical grafting [ 15 , 16 ].…”
