【摘要】 目的建立热重法对汽车轮胎橡胶进行鉴定的方法。方法应用热重法对12种轮胎橡胶样品进行分析。结果分别获得了12种轮胎橡胶的TG及DTG曲线和它们在三个阶段的失重百分率、DTG的峰温。结论可以方便地鉴别组成不同或牌号不同的轮胎橡胶制品,为划定与缩小嫌疑车辆的范围和认定肇事车辆提供依据。更多还原

【Abstract】 Objective To establish a identification method of tire rubber.Methods We use the thermogravimetry to analysis12kinds of tire rubber samples.Results We obtain their TG and DTG curves,as well as the percentages of zero gravity,the deviation percentages of zero gravity and the peak temperatures of DTG curves.Conclusion The tire rubbers with different composition or different brand can be distinguished by TG-DTG analgsis.更多还原
