不同制粒方式所制颗粒的粉体学特征与颗粒的引湿性关系的研究

Studies relationship between powder characteristic of kinds of granules and their hygroscopicity

目的:筛选吸湿性比较小的制粒方式。方法:用5种方法分别制粒,测颗粒的引湿性大小和粉体学特征,找出粉体学特征与引湿性大小的关系。结果:吸湿性较小的制粒方式是干式制粒和摇摆式制粒机二次制粒。结论:不同制粒方式所制颗粒的引湿性大小可以从颗粒的粉体学特征得以说明,筛选出的吸湿性比较小的制粒方式是干式制粒和摇摆式制粒机二次制粒。

Objective:To choose the granuling way for preparing granules that had low moisture-absorption characteristics.Method:Granules were prepared by five ways,for studying the relationship between characteristics of powder and hygroscopicity were determined.Result:The prepared ways of granuling that had low hygroscopicity were dry granuling and secondary swinging granuling.Conclusion:The hygroscopicity of granules can be explained by characteristics of powder,which are made in different granuling ways.The prepare...
