摘要
建立了一种利用傅里叶变换红外光谱技术快速检验复印纸的新方法。 采用傅里叶变换红外光谱技术对复印纸中填料种类和纤维素的结晶度进行了分析, 并研究了复印纸热老化和紫外光老化的规律。 以1 429与893 cm-1的吸光度比值表示纤维素的结晶度, 测定不同纸张样品的结晶度的标准偏差为0.010 7~0.016 0, 同一包纸样的平均标准偏差为0.014 8。 不同厂家不同牌号、 相同厂家不同牌号、 相同厂家相同牌号不同生产时间复印纸中添加的填料种类和纤维素的结晶度不同, 热老化和紫外光老化规律不同, 实现了对复印纸的鉴别, 为纸张的相同性比对和同一认定提供了一种实用的检验方法。
Abstract
A new method of fast identification of copy papers by Fourier transform infrared spectroscopy (FTIR) was developed. The kinds of filler and the cellulosic degree of crystallinity were analyzed by FTIR, and the ageing curves of cellulosic paper were studied with heating and ultraviolet light. The cellulosic degree of crystallinity was showed by the ratio of absorbance at 1 429 cm-1 to that at 893 cm-1, the standard deviation of different brands of copy papers was 0.010 7-0.016 0, and the standard deviation of the same brands of copy papers was 0.014 8. The kinds of filler and the cellulosic degree of crystallinity were different in copy papers from different brands of different manufacturing plants, different brands of same manufacturing plants and different manufacturing times of the same brands from the same manufacturing plants, and the curves of ageing were different with heating and ultraviolet light. The results of fast identification of copy papers by FTIR are satisfactory.
