Paper documents：Using atmospheric pressure non-equilibrium plasma technology to deacidify paper documents, after adjusting the parameters of deacidification agent type, deacidification agent flow rate, plasma energy density, deacidification times and other parameters, determine the appropriate deacidification parameters, and for a large number of Different materials of paper and painting pigments are deacidified. Experiments show that this method has a short deacidification time and is suitable for various types of paper. The surface of the paper after plasma deacidification is basically neutral or weakly alkaline, and can still exhibit good deacidification after artificial aging. Stability and mechanical properties. And this method will not affect the appearance, texture, mechanical strength of the paper, and the color of the ink and pigment on the paper surface.
