摘要
目的:探索用差示扫描量热法(DSC)鉴别药用高密度聚乙烯瓶中掺杂聚丙烯。方法:分别采用密度测定法、红外光谱法和差示扫描量热法鉴别高密度聚乙烯瓶。结果:差示扫描量热法不仅能鉴别高密度聚乙烯瓶掺杂聚丙烯,还能计算出掺杂的聚丙烯的比例。结论:差示扫描量热法可以弥补YBB标准中药用高密度聚乙烯鉴别方法的不足,可为药用高密度聚乙烯瓶鉴别方法的修订提供依据。
Objective：To use differential scanning calorimetry（DSC） to identify high-density polyethyene（HDPE） bottle adulterated with polypropylene（PP）.Methods：To identify HDPE bottle adulterated with PP with density,IR and DSC,respectively.Results：DSC can not only identify HDPE bottle adulterated with PP,but also can calculate the proportion of PP in HDPE bottle.Conclusion：DSC can make up of the deficiency of identification method in YBB standards.This study has provided the foundation of revision of identification method of HDPE bottles.
