摘　　要：目的:探讨利用差示扫描量热分析方法鉴别聚丙烯输液瓶材料。方法:在氮气氛围下,将样品以20℃·min^(-1)速率从40℃升至200℃后降温至40℃,再将样品以10℃·min^(-1)速率,从40℃升至200℃,恒温10 min,再将样品降温至40℃以下,绘制其DSC图谱。结果:聚丙烯输液瓶的熔融峰T m在145~150℃之间。结论:该方法准确、灵敏,操作简便,可用于聚丙烯输液瓶材料的鉴别,同时为聚丙烯输液瓶标准提高提供数据参考。Objective:To explore the use of differential scanning calorimetry(DSC)method to identify polypropylene infusion bottles material.Methods:The thermal analysis curve under nitrogen was determined at temperatures between 40℃and 200℃with a heating rate of 20℃·min^(-1),then cooled to 40℃at a rate of 20℃·min^(-1).The sample was heated from 40℃to 200℃at a heating rate of 10℃·min^(-1),held the specimen at 200℃for 10 min,then cooled to 40℃at a rate of 10℃·min^(-1).Results:The melting peak temperature(T m)of polypropylene infusion bottles was between 145-150℃.Conclusion:The proposed method is accurate,sensitive,and simple,and can be used for determination of polypropylene infusion bottles material,which can also provide reference for the standard improvement of polypropylene infusion bottles.
