影响农药悬浮剂物理稳定性因素和对策(Ⅰ)

Influence Pesticides SC Physical Stability Factor and Solutions

农药悬浮剂具有许多优点,包括水基性、无溶剂、无粉尘、容易混合、高的悬浮率、较低的包装体积和高的生物效率。近年来,农药悬浮剂发展十分迅速,但其贮存物理稳定性问题难以控制,已经成为开发和生产的障碍。论述悬浮剂不同聚集状态、物理稳定性的影响因素、流变性质、物理稳定性的测试技术方法。较详细地讨论了悬浮剂物理稳定性解决方法和高性能分散剂的选择。

Pesticide suspension concentrates possesses a number of benefits including water-based,solvent-free,dust-free,easier mixing,high suspensibility,lower packing volume and high biologicalefficacy.In recent years the pesticide suspension concentrates has developed very fast,but physical stability problem was difficult to solve and has become the obstacle in development and production.The different aggregation state of pesticides SC,influencing factor of physical stability,flow-change nature,testing technique of physical stability were described.The method to solve the physical stability and selection of high performance dispersing agent were discussed in detail.
