摘要
采用旋转流变仪研究不同制剂或基质液体制剂农药的稳定性与流变性质关系。测定多种液体制剂农药的屈服应力、流动曲线、稳定度、内聚能、粘度,并与样品稳定性进行比较。结果显示,不同品种样品之间,控制应力模式下测得的屈服应力大小顺序与各样品稳定性大部分符合,其他流变参数则不能对应。
The relationship between stability and rheological properties of pesticides with different formulations or bases was investigated by using the rotary rheometer.The yield stress,flow curve,stability degree,cohesive energy and viscosity of various samples were determined and compared with their stability.The results showed that the order of yield stresses determined under control-stress（CS）mode corresponded approximately to the stability of the samples while other rheological indexes were not.
