综合运用了比例法和对分法对35%乙草胺·莠去津可湿性粉剂的配方进行了研究,在较短时间内筛选出了该可湿性粉剂的较佳配方。其中润湿剂使用农乳500#与700#,以质量比3∶5混用,质量分数为5%;分散剂为木质素磺酸钠,质量分数为2.4%;其余为填料,其中白炭黑质量分数为25%,用凹凸棒土补至100%。该制剂中两种有效成分的悬浮率可达到80%以上,润湿时间在50s左右,且热贮稳定,可以满足生产需要。 The formula of the 35% acetochlor / atrazine WP was comprehensively studied by using the proportional method and the dichotomy method, and the better formulation of the WP was screened in a short period of time. The wetting agent uses 500 # and 700 # of agrochemicals, the mass ratio is 5%, the mass ratio is 5%, the dispersant is sodium lignosulfonate, the mass fraction is 2.4%, and the rest is filler, of which, white carbon black The mass fraction of 25%, attapulgite fill up to 100%. The preparation of the two active ingredients in the suspension rate can reach more than 80%, wetting time in about 50s, and heat storage stability, to meet the production needs.
