探讨大气污染物对档案与图书制成材料耐久性的影响,研究科学的防治技术已成为档案、图书保护工作中的一项重要课题。为促进此项工作在我国的开展,本文根据有关文献资料,分四部分介绍国外的研究情况,以资参考。 一、二氧化硫与纸账的pH值 1933年,美国国家标准局的研究人员金伯利等人首次进行了关于大气污染对图书破损影响的调查与定量分析。研究者对美国各地图书馆的书籍破损情况做了广泛的调查。从中选取一批具有代表性的书籍,对书页的pH值、a-纤维素、铜价、耐折度以及纸张纤维的种类进行了分析。结果表明,保存在大气污染严重城市中的书籍破损程度较大,含木素较多的纸张破损情况比破布浆纸、化学木浆纸严重。
To study the influence of atmospheric pollutants on the durability of archives and books made materials, researching scientific prevention and control technology has become an important issue in archives and book protection work. In order to promote this work carried out in our country, this article based on the relevant literature, in four parts introduced the research situation abroad, with reference to capital. First, the pH value of sulfur dioxide and paper books In 1933, the United States National Bureau of Standards researcher Kimberley and others for the first time on the impact of air pollution on the book damage investigation and quantitative analysis. Researchers conducted extensive investigations of book damage in libraries throughout the United States. A selection of representative books were selected to analyze the page pH, a-cellulose, copper price, endurance, and the type of paper fiber. The results showed that the books stored in cities with severe air pollution had a greater degree of damage. The damage of paper containing more lignin was worse than that of rags and chemical pulp paper.
