| Abstract:The study explored the effect of new plasma deacidification protection technology on the deacidification of different papers. The results showed that after deacidification of different papers by plasma technology, the pH value of the paper was maintained at about 8, and the tensile strength of the paper was also improved. After the artificial aging experiment, the deacidification effect remained stable. The color difference test of ink particles and pigments showed that after the paper was deacidified by plasma, the pH value of the paper was maintained at 7.5～8.9 and kept stable for a long time, and the tensile strength increased by 5% or more. After the aging experiment, the pH value of the paper decreased slightly; the tensile strength retention rate was above 90%; the paper surface was not smudged, the pigment did not fade, and the plasma deacidification treatment can ensure the stability of the ink and the pigment. |
