【摘要】：目的:考察低密度聚乙烯藥用滴眼劑瓶塑料摻雜情況,并分析其回收料與新料的差異。方法:采用差示掃描量熱法(DSC)分析8家廠家的滴眼劑瓶與原粒料的熔點(diǎn)值,并比較新料與一次料、三次料、六次料的熔融曲線、氧化誘導(dǎo)溫度以及氧化誘導(dǎo)時(shí)間。結(jié)果:差示掃描量熱法可以對(duì)低密度聚乙烯材質(zhì)進(jìn)行鑒別,并區(qū)分新料與回收料。結(jié)論:差示掃描量熱法在考察原料和產(chǎn)品材質(zhì)一致性上可以提供一定的依據(jù)。
[Abstract]:Objective: to investigate the plastic doping of low density polyethylene (LDPE) medical eye drops and analyze the difference between the recovered and new materials. Methods: the melting point values of eye drops bottles and raw pellets from 8 factories were analyzed by differential scanning calorimetry (DSC). The melting curves of new and primary, tertiary and six-order materials, the temperature of oxidation induction and the time of oxidation induction were compared. Results: differential scanning calorimetry can be used to identify low density polyethylene (LDPE) materials and distinguish new materials from recycled materials. Conclusion: differential scanning calorimetry can be used to investigate the consistency of raw materials and products.
