Research on the diffusion property of paper handwriting of ancient calligraphy and paintings in aqueous-phase mist deacidification
Aqueous-phase deacidification is a commonly used method for paper deacidification.However,it easily leads to the diffusion of handwriting(ink smearing/running),especially water-soluble handwriting,which has always been a difficulty in academic and industrial research.In our research,the wettability of papers and the diffusion properties of writing pigments were studied in detail,the anti-diffusing safety of papers and pigments in the process of deacidification was discussed,and the concept of diffusion critical moisture capacity was proposed.The results show that the diffusion critical moisture capacity is directly related to the solubility of writing pigments and the wettability of paper fibers:the better the water solubility of pigments and the wettability of paper fibers,the smaller the diffusion critical moisture capacity.The mist deacidification method has the characteristics of precisely adjustable amount of humidification and uniformly distributed small size of droplet particles.This method can accurately control the amount of deacidification agent according to the wettability of paper(k value)and the solubility of writing materials,in order to avoid the diffusion of handwriting.This work provides a feasible method for paper deacidification with good safety,and a scientific basis for the development and use of deacidification equipment.
