采用流点法初步选定氰·莠 (氰草津·莠去津 )水悬浮剂润湿分散剂组份 ,通过分散剂含量与粘度曲线确定其较佳用量 ,在此基础上利用正交试验设计方法以常温贮存分层率和悬浮率为指标对润湿分散剂、粘度调节剂组份及其配比进行优选 ,确定了较佳配方并进行了贮存稳定性和除草效果验证。该方法提高了筛选配方的科学性和效率。
The initial wetting and dispersing agent component of cyanuric sulfate (cyanuric acid and atrazine) was selected by flow-point method. The optimum dosage of dispersant was determined by the content and viscosity curve of dispersant. On this basis, orthogonal design Methods The wetting and dispersing agent, the components of viscosity modifier and the ratio of them were optimized with the storage rate of stratification and the rate of suspension at room temperature as the index. The optimum formula was determined and the storage stability and herbicidal effect were verified. This method improves the scientificness and efficiency of screening formulations.
