微粉工程是利用现代科学技术研究粉末的形成、特性、分级、检测、传输、加工及应用的一门基础学科,现已广泛应用于国民经济各个领域。 制药行业应用的微粉工程技术在原料药生产和制剂加工过程中都有十分重要的作用。细度往往是一项重要的质量指标。某些原料药本身就有细度的要求。如普鲁卡因青霉素,国际上要求细度在5～15μm,目前我国为40μm以上;我国维生素C原料 Powder engineering is the use of modern science and technology research powder formation, characterization, grading, detection, transmission, processing and application of a basic discipline, has been widely used in various fields of the national economy. The micropowder engineering technology used in the pharmaceutical industry plays a very important role in the production of APIs and in the processing of pharmaceutical preparations. Fineness is often an important quality indicator. Some APIs themselves have fineness requirements. Such as procaine penicillin, the international requirements of fineness in the 5 ~ 15μm, at present, China is more than 40μm; China’s vitamin C raw materials
