改性纳米MgO氟碳脱酸液的制备及其纸张脱酸性能
Preparation and deacidification performance for paper of modified nanometer MgO fluorocarbon deacidification solution
摘要
Abstract
Nanometer MgO was synthesized via anodic oxidation electrolysis and modified with polyvinylpyrrolidone(PVP),cetyltrimethylammonium bromide(CTAB),and sodium dodecylbenzenesulfonate(SDBS).The dispersion and stability of nanometer MgO in methyl perfluoroisobutyl ether fluorocarbon solvent were investigated.The nanometer MgO fluorocarbon solvent was used as a deacidification solution for the Qing Dynasty paper.The effects of nanometer MgO fluorocarbon deacidification solution containing different surfactants on paper deacidification performance were studied.The results showed that nanometer MgO modified with 2%CTAB exhibited the best dispersion in the fluorocarbon solvent and achieved the best deacidification effect,remaining suspended for 60 minutes.After treatment with the deacidification solution,the pH of the paper increased to 7.51,and the alkaline reserve was 0.51 mol/kg.The whiteness of the paper remained almost unchanged,with a slight reduction in color difference.The tensile strength increased by 64.5%,showing that the solution provided excellent protection for the paper and could extend its shelf life.关键词
