84溶液清除蓝黑墨水斑的效果及对纸张性能的影响实验分析

Experimental Analysis on the Effect of 84 Solution to Remove Blue-black Ink Stains and its Effect on Paper Properties

纸质档案被蓝黑墨水污染后,或影响档案原貌,或影响信息识读,为保护原件,应选择适当方法去除这些污斑。选用84溶液对宣纸和书写纸上的蓝黑墨水斑进行清洗实验,探讨清除蓝黑墨水斑的方法及效果,同时通过老化实验研究氧化去污后对纸张性能的影响。结果表明:84溶液浓度、处理时间、温度、pH等因素对污斑清除效果有影响,低浓度的84溶液即能够有效清除蓝黑墨水斑,且短时间内对纸张性能的影响较小。实际部门在开展档案上蓝黑墨水斑的清除工作时可以选用低浓度的84溶液。

After polluted by blue and black ink, it would have an impact on the original appearance and information literacy of archives.In order to protect the original, appropriate methods should be selected to remove these stains. In this paper, the 84 solution was used to clean the blue-black ink spots on rice paper and writing paper.The method and effect of removing blue-black ink spots were discussed. At the same time, the effect of oxidative decontamination on paper properties was studied by aging experiment. The results showed that:84 solution concentration, treatment time, temperature, pH and other factors have an effect on the stain removal effect. The low concentration of 84 solution can effectively remove the blue-black ink spots, and has little effect on the paper performance in a short time. The actual department can use a low concentration of 84 solution when carrying out the cleaning of blue and black ink spots on the archives.
