摘　　要：目的建立热差/热重检验方法鉴别常见塑料。方法使用差热/热重双重检验的方法。结果能准确鉴别不同种类的塑料,尤其是对种类相近的塑料,能有效的加以区分。结论该方法检验常见塑料,检材用量少、区分率高,操作简便,具有很强的实用性。Objective To establish a method for identifying plastic. Methods 12 plastic samples collected from market and manufactory were tested by DSC and TG, then the thermic variation and weight variation were analyzed. Results The ther mic variation and weight variation of 12 plastic samples were different significantly. Conclusion The method is accurate and can be used for identifying plastic.
