Preparation of total glucosides in paeony sustained-release pellets by fluidized bed coating method 流化床包衣法制备芍药总苷缓释微丸的研究
This paper describes that the coating technology of using a gas mixture of propylene ( C 3H 6) and acetylene ( C 2H 2) in fluidized bed coating furnace was developed in order to eliminate the thermal effects of propylene decomposition. 该文介绍了在流化床包覆炉中采用丙烯(C3H6)和乙炔(C2H2)的混合气体作为反应体系的包覆工艺,以消除只用丙烯作为包覆气体时产生的热效应。
Application of Insulating Powder Coatings on the Bus-bar of High-voltage Switch Chamber by Fluidized Bed Coating Process 流化床涂覆在高压开关柜母线绝缘上的应用
Ultrafine powders coating in fluidized bed reactor by chemical vapor deposition ( CVD) method to synthesize TiO_2-ZnS composites were studied. Simultaneously SEM 、 XRD 、 EPMA etc were successfully used to study the structures of composite particles and the characteristic of coating process. 为了制备TiO2-ZnS复合粒子,采用流态化化学气相沉积(CVD)法,探讨了其包覆工艺,借助SEM、XRD、EPMA等测试手段研究了复合粒子结构和包覆过程特征。
Fluidized bed coating is the principal method coating on the dosage form with small particles, which includes top spray and bottom spray. 流化床包衣已经成为目前对小粒径分散性剂型包衣的首选包衣方式。其主要分为顶喷与底喷两种形式。
