空气污染物对文书档案纸张保存耐久性的影响研究

Effects of Air Pollutants on the Durability of Paper Storage

空气污染物中的粉尘、烟、飞灰、黑烟、雾、煤烟尘、悬浮微粒等会促使文书档案纸张加速氧化分解,导致纸张中的纤维素氧化腐败,从而降低纸张保存的耐久性,分析空气污染物对文书档案纸张保存耐久性的影响。对不同成分的文书档案纸张进行实际检测分析,研究表明,空气污染物对纸张具有加快氧化分解的作用,使得纸张的内部碳结构不稳定,在温度、湿度、光照等催化作用下,空气污染物加速了纸张的化学分解,从而导致纸张损毁,在纸张保存中,需要注意环境大气污染,采用空气净化和防潮等手段,提高纸张保存的时效。

air pollutants in the dust,smoke,fly ash,black smoke,fog,coal soot,total suspended particulates will accelerate the paper oxidation decomposition,resulting in paper cellulose oxidation corruption. In order to reduce the durability of paper preservation,analyze the influence of air pollutants on the paper storage durability,analyze the types of air pollutants and the chemical principle of paper oxidation decomposition. And the actual analysis of the different components of the paper. The results show that air pollutants can accelerate the oxidation and decomposition of the paper. The internal carbon structure of paper is unstable. Under the catalysis of temperature,humidity and light,air pollutants accelerate the chemical decomposition of paper,resulting in paper damage,in the paper preservation. Attention should be paid to environmental air pollution,air purification and moisture-proof measures should be adopted to improve the efficiency of paper preservation.
