整本图书智能化脱酸工艺的初步研究

针对酸化文献的纸张特点和水溶液脱酸法的利弊,研制开发一套文献智能化脱酸保护设备尤为必要,研制开发的文献智能化脱酸保护技术,可以实现自动流量调节、自动喷涂并辅以自动翻页技术,在实现脱酸的同时对纸质文献进行保护。为达到理想的脱酸效果,需严格控制脱酸过程,最后确定:对pH在5以下的图书,应控制脱酸液质量分数为5%,恒流泵输送流速为10mL/min,压缩机气流压力为0.16MPa时喷涂效果最好。脱酸后的纸样,采用纸张性能、碱性物质残留、纸张疏水性能、碱性粒子分布情况等评判脱酸效果,均证实该智能化脱酸方法安全、有效。

Research on automated deacidification technology used for acidified whole books

Considering acidification of literature paper and the drawbacks of traditional deacidification methods, we developed a set of automated literature deacidification technologies to automatically process the procedures. The process includes controlled automatic spraying and automatic page-turning. The process is an ideal conservation method and a good deacidification method. The deacidification process was strictly controlled in order to achieve ideal effects. The optimum parameters for books having a pH below 5 were set as follows:1) the mass concentration of nano-particulate magnesium oxide was 5%; 2) the pump output flow rate was 10 mL/min and; 3) the air pressure was 0.16 Mpa. The paper properties, residual alkalinity, waterproof characters and particle distribution on the paper after deacidification treatment were tested to evaluate the deacidification method. The results show that the automated deacidification method we developed is safe and effective.
