摘  要:
研究了一种环境友好型制剂——10%甲基嘧啶磷水乳剂,筛选了一系列不同HLB值乳化剂,选择出HLB值为13.4的乳化剂A为最佳乳化剂,并进行了乳化温度和乳化时间的筛选实验及不同pH值下水乳剂的稳定性实验。结果表明,加入10%乳化剂,乳化温度30~35℃,乳化时间为10~15min,可配制稳定的水乳液,即所配制的10%甲基嘧啶磷水乳剂有良好的冷、热贮和稀释稳定性。实验还确定了可行的技术指标和最佳工艺路线。

摘  要:
In order to enlarge the application study of pirimiphos-methyl and satisfy the request with the market,10% pirimiphos-methyl EW was studied.The optimal HLB was found to be 13.4 by evaluation of 10% pirimiphos-methyl EW.According to the optimal HLB,different emulsifiers were studied.The result showed that A# emulsifier was the best.The 10% pirimiphos-methyl EW prepared under optimal temperature and times has good stability for cool,heat and water dilution.The technic and index were determined also.
