摘　　要：当前图书馆大多以低温冷冻技术进行害虫防治,为探究此技术对于图书纸张性能的影响,以道林纸、字典纸、双胶纸、打字纸、新闻纸开展180个周期低温冷冻处理,以对比测试其与室温避光保存状态下的纸张白度、抗张强度、撕裂度、耐折度等性能,以及相对变化率。结果表明,五种纸张试样经过全周期低温冷冻之后,白度、抗张强度、撕裂度、耐折度可大体保持不变,说明低温冷冻技术对于图书纸张性能的影响并不显著;以低温冷冻技术进行图书纸张害虫防治,不仅不会影响纸张性能,还可缓解漂白程度过高的打字纸保存时的白度与抗张强度下降程度,非常适用于图书害虫防治操作。At present,most of the libraries use low-temperature freezing technology to control pests.In order to explore the impact of this technology on the performance of books and paper,180 cycles of low-temperature freezing treatment with Daolin paper,dictionary paper,offset printing paper,copy paper and newsprint was carried out,and the properties of the paper under the condition of room temperature and dark storage,such as whiteness,tensile strength,tear strength,folding resistance and relative change rate were tested.The results showed that the whiteness,tensile strength,tearing strength and folding resistance of five kinds of paper samples remained unchanged after the whole cycle of low-temperature freezing,which indicated that the effect of low-temperature freezing technology on the properties of book paper was not significant.Using low-temperature freezing technology to control book paper pests would not affect the paper properties,and also alleviate the storage of typewriting paper with high bleaching degree.It is very suitable for pest control of books.
