【摘要】 通过加热转印的方式将纸张上的打印字迹墨粉提取下来,再用金刚石池压片方式进行制样,显微傅立叶变换红外光谱法对15种常见激光打印文件字迹的墨粉成分进行分析。对红外光谱主要官能团的解析结果表明,常见激光打印机墨粉主要成分为苯乙烯和甲基丙烯酸甲酯的共聚物,实验样本的墨粉种类可分为两大类。更多还原

【Abstract】 Toners on laser printing document were exacted by heat;samples of different toners were prepared by diamond cell,15 samples were analyzed by fourier transform infrared spectrum.It demonstrated that copolymer of styrene and methyl methacrylate is main component of laser printing toner by analysis of functional group in infrared spectroscopy,experiment samples can be divided into two categories by spectroscopy.更多还原
