摘要
在犯罪活动中,犯罪分子经常利用烧毁文件手段销毁书证、物证,以达到推卸责任,掩盖违法犯罪事实的目的;在一些重大爆炸、火灾事故后,会残留有一些烧毁的文件。对这些文件的处理、信息辨读及案件检验对侦破案件、查找事故原因有重要意义。文件烧毁后,纸张变脆,保存能力差,通常呈现焦化、炭化或灰化三种表观变化状态,但是这三种状态的形成机理及其如何区别一直没有一个清晰的界定,导致三个词语的混淆使用。本文使用热重分析法,研究纸张烧毁的不同程度和阶段,并对其烧毁机理进行探讨。在此基础上,通过实验配制了烧毁文件整复溶液,可以根据纸张烧毁的不同程度,对文件进行软化摊平和整复成膜操作,便于下一步的文件检验工作。
In relevant criminal cases, burning is often used as means to destroy documentary and/or material evidence to mask criminal facts. There are also some burned files or documents left in the scenes of explosion or fire. The examination of burned documents is helpful to find out the cause of the accident and/or detect the criminals. The charred document presents state of the charred, carbonized or ash, which is neither clearly understood nor did the mechanism of the charring process. To clarify the mechanism of burned document, thermal analysis was used to analyze the different stages of burning. Based on this, new handling solution was prepared to make charred document smooth and had an effective result in this kind of document examination.
