橡胶制品上潜在手印的显现方法研究

Research on the Revealing Hidden Fingerprints on the Rubber Products

目的:建立有效地显现橡胶制品上汗潜手印方法。方法:本文主要介绍了通过502滤纸贴附显现汗潜手印、粉末刷显两种方法对橡胶制品上的汗潜手印进行显现比较研究,主要是对新鲜、1小时、4小时、8小时、12小时、16小时、24小时时段的手印进行显现比较研究。结果:本文研究发现无论橡胶表面光滑程度和手印遗留时间的长短如何,利用"502"胶显现均有很好的显现效果;而粉末刷显对于上述两种情况则效果不理想。结论"502"胶显现法是橡胶制品上汗潜手印显现最理想和有效的方法。

Objective:To establish an effective to reveal sweat latent fingerprint on rubber products,.Methods:This paper introduces the comparative study between the502filter paper attached to show thesweat latent fingerprint and powder-brush method mainly for fresh fingerprints,fingerprints of1hour,4hours,8hours,12hours,16hours and24-hour.Results:The research found that regardless of smoothnessof the rubber surface and length of time of fingerprints left on them,using the“502”rubber shows goodresults;results by powder-brush are not satisfactory.Conclusion:“502”glue is the best and effective wayto reveal sweat latent fingerprints on rubber products.
