摘要
采用水相脱酸法对纸张进行脱酸处理,具有经济性强、脱酸效果理想、操作难度相对较低等优点.以碳酸氢钠水溶液为例,对其应用于图书文物水相脱酸的效果进行分析,分析了碳酸氢钠水溶液对图书文物纸张表面pH值、耐折度、抗张强度等的影响.结果表明:当碳酸氢钠水溶液中碳酸氢钠质量分数为0.2％时,溶液的综合脱酸效果最为理想.
Abstract
The water phase deacidification method for paper deacidification has the advantages of strong economy,ideal deacidification effect and relatively low operation difficulty.Taking sodium bicarbonate aqueous solution as an example,this paper analyzes the effect of sodium bicarbonate aqueous solution on the surface pH value,folding resistance,tensile strength and so on.The results show that when the mass fraction of sodium bicarbonate in sodium bicarbonate aqueous solution is 0.2％,the comprehensive deacidification effect of the solution is the best.
