Chlorimuron-ethyl water dispersible granule preparation method

Abstract

The invention discloses a chlorimuron-ethyl water dispersible granule preparation method. The chlorimuron-ethyl water dispersible granule preparation method comprises the steps that raw materials aredried; according to the raw material ratio of chlorimuron-ethyl water dispersible granules, appropriate dried raw materials are selected; the dried raw materials are mixed; the mixture is subjected tofirst-time smashing by using a rolling device to obtain initial base powder; the initial base powder is subjected to the second-time screening by using an airflow smashing machine to obtain a finished product base powder; the finished product base powder is kneaded and granulated with added water; the granules are dried; the dried granules are screened to obtain chlorimuron-ethyl water dispersible granule. Firstly, the prepared raw materials are dried, the damped raw materials are prevented from affecting the preparation quality, and meanwhile two-step smashing is performed, so that the raw materials are mixed more fully, and the generating efficiency of the finished product base powder is also improved.

Description

technical field [0001] The invention relates to a preparation method of chlorimuron-methyl water-dispersible granules, which belongs to the field of preparation of agricultural water-dispersible granules. Background technique [0002] Chlorimuron-methyl is a selective pre-emergence and post-emergence herbicide, which can be absorbed by plant roots, stems, and leaves, conduct up and down in the plant body, and play a herbicidal effect on the vigorously growing meristematic cells. It is mainly used for the control of broad-leaf in soybean fields leaf weeds. The traditional preparation method of chlorimuron-methyl water-dispersible granules is to directly pulverize the raw materials through a jet mill to obtain mother powder. Since some raw materials stored during preparation will be damp, the preparation quality will be affected. Contents of the invention [0003] In order to solve the above technical problems, the invention provides a preparation method of chlorimuron-meth...
