| 摘要:本研究探讨了新型等离子体脱酸保护技术对不同纸张脱酸效果的影响。结果表明，不同纸张经等离子体脱酸技术处理后，纸张的pH值保持在8.0左右，纸张抗张强度也有一定程度的提高，且经人工老化实验后，脱酸效果依然保持稳定。对油墨颗粒和颜料色差测试表明，纸张经等离子体脱酸处理后，纸张pH值保持在7.5～8.9并能长期稳定，抗张强度提高5%以上；经老化实验后，纸张pH值微降、抗张强度保留率90%左右；纸面字迹不晕染、颜料不褪色，等离子体脱酸处理可以保证油墨和颜料的稳定性。 |
| 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. |
