| 摘 要： | 用TG-DTA差热热重联用分析仪在升温速率为20 ℃/min、高纯氮气流量为20 mL/min的气氛条件下对输液袋、卫生纸和注射器3种典型医疗废物试样进行了热解实验和差热分析。结果表明，几种试样热解过程均为吸热反应，而且实验测得的DTA曲线的形状比较复杂，对称性较差，基线偏移较大；在医疗废物的热解过程中，最大失重速率发生点的温度一般要比达到瞬时热平衡点的温度稍低。

| Abstract: | The thermal decomposition and differential thermal analysis process of three typical medical wastes(infusion bag,toilet paper,injector)were experimentally investigated by using the TG-DTA apparatus,the samples were heated at 20℃/min in 20 mL/min nitrogen flow.The results show that the thermal decomposition of medical waste is a heat-absorption process.The curve shape is complex,and non-symmetric.There is a significant deviation in base line.The temperature for the maximum weight loss rate is lower than that for the instantaneous thermal balance. |
