摘要
目的提出一种采用改性热塑性树脂来提取案发现场立体痕迹的新方法。方法利用市场上常见的热塑性高分子合成树脂,通过对其熔融流动性及指数的改变,使之能适应提取立体痕迹的需要,并与常用的硅橡胶提取材料的性能测试数据进行了分析比较。结果该方法提取的立体痕迹模型反映细微特征明显。结论操作方法简便快捷,性能更为优越,易于收藏保存。
Objective To establish a novel method for taking the three?dimensional marks in crime scene.Method Thermoplastic synthetic resin was modified for suiting to crime scene marks casting.Result As compared with silicone rubber method,more fine marks have been taking with modified thermoplastic synthetic resin.Conclusion The method is simple and effective,also resin casting of mark is easy to store.
