【摘要】 对微胶囊的控制释放机理进行了初步探讨,详细讨论了不同工艺条件下制备的尿醛树脂微胶囊的囊心随时间的缓释曲线,并通过平均粒径,膜厚,表观扩散系数等相关参数揭示了不同因素对微胶囊释放速率的影响规律。更多还原

【Abstract】 Controlled-release mechanism of microcapsule was discussed,and cumulative release curve of urea-formaldehyde microcapsule by different preparation processes was introduced.Effect of correlative parameters such as aver-age diameter,film thickness and apparent diffusion coefficient on the release speed of microcapsule was revealed.更多还原
