电气火灾物证鉴定抛光工艺的研究

Study on polishing technology of physical evidence collected from electrical fire scene

通过实验研究,确定以绒布、水性研磨膏、纯净水与甘油混合液为抛光材料的电气火灾物证鉴定抛光新工艺,可对铜导线、铝导线、黄铜接插件、铸铝和钢等火灾现场提取的金属材料痕迹物证样品进行有效地抛光处理。该工艺既满足电气火灾物证鉴定的技术要求,又能确保物证鉴定工作人员的身体健康。

According to the experimental studies,the flannelette,the water soluble abrasive,and the mixture of pure water and glycerol are determined to polish the metallographic specimens of physical evidence collected from fire scene,such as copper conductor,aluminum conductor,brass,cast aluminum,steel and etc.This new technology can both satisfy the identification requirements of electrical fire,and ensure the heath of operating staff.
