摘  要:
研究了增稠剂黄原胶用量对50%丁醚脲水悬浮剂流变性的影响。分别以黄原胶用量0.1%、0.2%、0.3%制备50%丁醚脲水悬浮剂,结果发现:随着黄原胶含量的增加,水悬浮剂黏度增加,屈服值τH变大,流动行为指数n变小,假塑性现象越来越明显,表明黄原胶是良好的结构调节剂。其中以黄原胶用量为0.2%制备的丁醚脲悬浮剂黏度适中,经冷、热贮和常温贮存后仍为假塑性流体,效果最佳。

摘  要:
The effect of the content of thickener xanthan gum on the rheological properties of diafenthiuron 50%SC was studied.The diafenthiuron 50%SC were prepared with the content of xanthan gum by 0.1,0.2,0.3%respectively,the results showed that the viscosity and the yield valueτ H increased with the content of xanthan gum increasing,but the flow behavior index n was decreasing,and the trend of pseudoplasticity phenomenon was increasing apparently,it proves that xanthan gum was a good structural regulator.The best diafenthiuron 50%SC with appropriate viscosity was obtained with 0.2%xanthan gum used,and it was still a pseudoplastic fluid through cold,thermal and room storage.
