摘要:
采用真空冷冻干燥法对脱酸后的纸质历史文献进行干燥,以确保历史文献脱酸干燥后形状良好.采用曲线分析法得出试验纸质历史文献的共晶点温度,研究了部分预冻过程和干燥过程的参数.通过分析冻干曲线,验证了辐射导热联合干燥温度分布均匀,干燥效果良好.试验结果表明,脱酸后历史文献的暗黄度明显减轻,纸张酸性能基本去除,真空冷冻干燥法能有效控制历史文献的收缩变形.
Abstract:
In order to keep a good shape after deacidification and drying,a vacuum freeze-drying method is arried out on the deacidified paper literature.The method of curve analysis is used to find out the temperature of eutectic point and partial parameters of pre-freezing and drying are studied.Radiation and thermal conductivity of heating methods shows a good result by analyzing the freeze-drying curve.The results of experiment indicate that the dark yellow of paper reduces signigicantly and the acid of paper is eliminated basically,and vacuum freeze-drying can control the shrinkage deformation of paper literature effectively.
