农药悬浮剂的开发现状和展望

Development Status and Prospects of Pesticides Suspension Concentrates(SC) Formulation

悬浮剂比可湿性粉剂有更多优点,如无粉尘、悬浮率高、润湿性好、较低的包装体积和生物效率高。论述了农药悬浮剂的进展、基本组成、前景和加工技术,较详细地讨论了悬浮剂剂型的物理稳定性和分散剂的选择以及影响悬浮剂物理稳定性的主要技术障碍——分子长大现象,并从原理、结构设计、制剂技术等多方面总结了多层静电屏蔽系统这一新制剂技术的研究情况。

Suspension concentrates offer a number of benefits over the wettable powder formulation.These include：an absence of dust, improved suspensibility on dilution,improved wetting,lower packing volume and enhanced biological efficacy.The development status and prospects of pesticides SC formulations are described.We discussed in more detail the physical stability and the choice of dispersing agent and the main technical obstacle affect the physical stability-particle reaggregation and summarized the multi- layer electrostatic shield system of this new technology from the principle、structure design、processing techniques etc.
