新型复写纸又称为无碳复写纸,目前,新型复写纸已在银行、税务、电信、邮电、保险、餐饮等各个领域得到广泛的应用,但随之而来的利用新型复写纸进行违法犯罪活动也有增多的趋势。本论文应用傅立叶变换红外光谱分析法首先对新型复写纸的纸张及色料种类进行了分析鉴别,实验结果证明,采用傅立叶变换红外光谱透射法和溴化钾压片制样技术可以对不同品牌、生产厂家的新型复写纸样品进行有效区分。
At present, the new type of carbon paper has been widely used in various fields such as banking, taxation, telecommunications, post and telecommunications, insurance, catering, etc. However, there has also been an increase in the use of new carbon paper for criminal activities trend. In this dissertation, Fourier transform infrared spectroscopy (FTIR) was used to analyze and identify the types of paper and colorants of new carbon paper. The experimental results show that using Fourier transform infrared spectroscopy and KBr sample preparation technology can distinguish different types of paper, Manufacturers of new carbon paper samples for effective distinction.
