聚氨酯组合物提取工具痕迹效果研究

Research on the Trace Effect of Polyurethane Composite Extraction Tools

本文对聚氨酯组合从物理、化学性质等角度展开分析研究,根据反应特性提取以木质、金属、塑料、漆面四种常见的承痕客体上的工具痕迹,以硅橡胶制模法为对照实验,在操作时间、材料性质、提取效果三方面进行对比,来确定聚氨酯组合物是否能代替硅橡胶制模法的可行性。

This article analyzes and studies polyurethane composites from the perspectives of physical and chemical properties.Based on the reaction characteristics,tool marks are extracted from four common scratch bearing objects:wood,metal,plastic,and paint surface.The silicone rubber molding method is used as a control experiment,and the feasibility of polyurethane composites replacing the silicone rubber molding method is determined by comparing the operation time,material properties,and extraction effect.
