Abstract
Thermoplastics based on polyolefins, including polypropylene, high-density polyethylene and low-density polyethylene, are extensively utilized across various packaging sectors. The selection of these materials for specific applications is influenced by multiple factors, such as the polymer's absorption characteristics and the impact on its mechanical properties when in contact with the packaged product. This study presents an experimental methodology designed to simulate the effects of absorption on the macroscopic and microscopic properties of high-density polyethylene bottles in contact with amyl acetate. Macroscopic degradation was evaluated by modeling mechanical damage using unified theory and the energy method. Analytical techniques such as gravimetric analysis, scanning electron microscopy and Fourier transform infrared spectrometry were employed. The findings of this research provide valuable insights for suppliers and industries to experimentally determine the usability and safety intervals of plastic packaging through comprehensive macroscopic and microscopic analyses within relatively short timescales. © 2024 Society of Chemical Industry.
研究乙酸戊酯吸附对高密度聚乙烯瓶性能的影响
基于聚烯烃的热塑性塑料,包括聚丙烯、高密度聚乙烯和低密度聚乙烯,广泛应用于各种包装部门。为特定应用选择这些材料受到多种因素的影响,例如聚合物的吸收特性以及与包装产品接触时对其机械性能的影响。本研究提出了一种实验方法,旨在模拟吸收对高密度聚乙烯瓶接触乙酸戊酯的宏观和微观性能的影响。采用统一理论和能量法建立力学损伤模型,对宏观退化进行评价。采用了重量分析、扫描电镜和傅里叶变换红外光谱等分析技术。本研究结果为供应商和行业提供了有价值的见解,通过实验确定塑料包装的可用性和安全间隔,在相对较短的时间尺度内通过全面的宏观和微观分析。©2024化学工业学会。
