摘要：An effective and integrated method for deacidification has become an urgent issue in the conversation of paper-based materials with natural aging of books, archives and paper relics. In this research, an efficiency of innovative method for paper deacidification using subcritical R134a combined with presynthetic Ca(OH)(2) nanoparticles was evaluated by pH, alkaline reserve, colorimetry and tensile strength. The physicochemical properties of the deacidifying agents and paper samples before and aft ...More
An effective and integrated method for deacidification has become an urgent issue in the conversation of paper-based materials with natural aging of books, archives and paper relics. In this research, an efficiency of innovative method for paper deacidification using subcritical R134a combined with presynthetic Ca(OH)(2) nanoparticles was evaluated by pH, alkaline reserve, colorimetry and tensile strength. The physicochemical properties of the deacidifying agents and paper samples before and after deacidification were characterized by XRD, SEM and FTIR. Compared with traditional spraying method for Ca(OH)(2) nanoparticles, the subcritical R134a deacidification system (due to its good solvent diffusivity and compatibility) had an obvious advantage in evaluations for all the paper samples. The innovative deacidification was expected to realize the integration of cleaning and deacidification in one working procedure. (C) 2018 Elsevier Masson SAS. All rights reserved. ...Hide
