摘要
采用植物提取的天然脱酸剂TS3、TS4对酸化纸张浸泡脱酸,主要考察了温度、时间、脱酸剂质量分数对脱酸效果、纸张色度的影响。结果表明,适当升温、延长脱酸时间有利于增强脱酸效果,而脱酸剂稀释后脱酸效果下降;脱酸后纸张色度有轻微变化,纸张呈灰褐色。
Deacidification of aged paper was studied using natural acid stripping agents. Acid papers were deacidified by soaking in the natural acid stripping agents TS3 and TS4. Effects of temperature, time and dilution ratio of the acid stripping agents on deacidification and chromaticity of the paper were investigated. Results showed that suitable raising temperature and extending time of deacidification was beneficial to enhance deacidification, but deacidification effect decreased when the acid stripping agents were diluted. After deacidification, paper chromaticity changed slightly and paper color became taupe.
