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
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 typeand wettability between essence and the copolymer pallets were analysed by measurements of fouriertransform infrared spectrum,surface tension,contact angle and specific surface area.The technical factorsaffecting absorptivity such as the charge ratio,temperature,pressure and stirring speed were studied by series of adsorption experiments The results showed that the adsorption of essence on the surface of ethylene-vinyl acetate copolymer pallets is physical in nature Essence couldn’t moisten the surface of ethylene-vinyl acetate copolymer pallets absolutely,but it could be soaked into the surface of the pallets partly.Adsorptivity could be increased by enhancing the temperature,pressure and stirring speed,but the extension of adsorption time had little influence on adsorptivity.
