英文: Abstract: The interface behavior between essence and ethylene-vinyl acetate copolymer pallets was studied so that necessary data were obtained to guide the preparation of fragrant masterbatch.The adsorption type and wettability between essence and the cop
中文: 文摘:研究了香精与乙烯/醋酸乙烯共聚物粒子之间的界面行为,以便为香型母粒的制备提供必要的理论依据.利用傅立叶变换红外光谱、表面张力、接触角及比表面面积等测定手段,分析了香精与载体之间的吸附类型和润湿作用.并通过一系列吸附实验,讨论了配料比、温度、压力、搅拌等工艺条件对吸附量的影响.结果表明,香精在乙烯/醋酸乙烯共聚物粒子表面的吸附为物理吸附;香精无法完全润湿载体粒子表面,但可以对其形成部分浸润;提高温度、压力、搅拌速度可以增加吸附量,而延长吸附时间对增加吸附量贡献不大.
