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.
