影响档案文件寿命的外界因素很多,其中最主要的是空气的温度和湿度。因为,档案纸张的发黄变脆,字迹褪色,霉烂和发生虫害等,几乎都与空气的温、湿度有密切关系。档案纸张对温、湿度的适应性是有一定限度的。纸张的安全水分大约是5-12%,档案库房最适宜的温度是14-24℃,最适宜的相对湿度是45-60%。而档案库内温、湿度的变化,直接受到库房外自然气候变化的影响。因此,档案工作者要根据库房外自然气候的变化,对库内温、湿度进行有效地调控。
There are many external factors that affect the life of archives, the most important of which are the temperature and humidity of the air. Because the archival yellow brittle paper, faded, mildew and pests, almost all with the air temperature and humidity are closely related. Archival paper on the temperature and humidity adaptability is a certain limit. The moisture content of the paper is about 5-12%, the most suitable temperature in the archive warehouse is 14-24 ° C, and the most suitable relative humidity is 45-60%. However, the change of temperature and humidity in the archive is directly affected by the natural climate change outside the warehouse. Therefore, archivists should be based on changes in the natural climate outside the warehouse, the library temperature and humidity for effective regulation.
