酸碱性物质对档案资料用纸老化的影响

Effect of Acidic and Alkaline Substances on the Aging of Archival and Magazine Paper

研究了酸碱性气体对档案资料用纸耐久性的影响。结果表明 ,含NH3的空气、含 (CH3) 2 NH的空气和CO2 气体能够提高纸的抗老化性 ,而SO2 和HCl气体会破坏纸的强度 ,降低其耐久性。

Effect of acidic and alkaline gas on the permanence of archival and magazine paper was studied. The results show that air with NH 3, air with (CH 3) 2NH and CO 2 gas could enhance the aging resistance of paper,but SO 2 and HCl gas can destroy paper strength,and result in decrease in paper permanence.
