化学法制备微胶囊机理及过程控制

微胶囊技术是一种用成膜材料把固体或液体包覆成微小粒子的技术,并在很多领域得到了应用。传统的微胶囊制备方法从原理上大致分为化学法、物理法和物理化学法三大类。化学法制备微胶囊机理明确,具有影响因素多、成囊性能可控性强等特点。主要介绍了化学法制备微胶囊的原理、方法及过程控制。

Principle and Process Control of Preparing Microcapsule by Chemical Methods

The microencapsulation is a technology of using a film-forming material to coat solid or liquid to form tiny particles, and it has been applied in many fields. The traditional microencapsulation includes chemical methods, physical methods and physical-chemical methods in principle. The chemical preparation of mierocapsule has many characteristics, such as the dear mechanism, many influence factors and better controllability to form capsule. The principle, methods and process control of preparing microcapsule by chemical methods are introduced.
