Abstract:
Objective:To explore the use of differential scanning calorimetry(DSC)method to identify polypropyl-ene 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(Tm)of polypropyl-ene infusion bottles was between 145-150 ℃.Conclusion:The proposed method is accurate,sensitive,and sim-ple,and can be used for determination of polypropylene infusion bottles material,which can also provide reference for the standard improvement of polypropylene infusion bottles.
