Embodiment 1

[0019] A water-dispersible granule of hexazinone and diuron original medicine, comprising hexazinone and diuron original medicine, auxiliary agent, carrier filler and water, wherein, the content of hexazinone is 12-15%; the content of diuron is 40% ~48%, the auxiliary agent includes 5~10% of disintegrant, 10~30% of adsorbent, 5~15% of binder, 5~15% of wetting agent, 5~15% of polymer dispersant, carrier 10-30% filler.

[0020] In this example, the carrier filler is one or more of porous materials such as expanded perlite, talcum powder, sawdust, charcoal powder, floating glass beads, and foamed plastics. The diameter is 40-120 microns, and the carrier filler has both hydrophobicity and wettability; the disintegrating agent can disintegrate and peel off the large granules from the outside to the inner layer, and at the same time, the granules can disintegrate in blocks, and the large granules disintegrate It is small particles, and the small particles continue to disintegrate i...

Abstract

The invention discloses a hexazinone-diuron original medicine water-dispersible granule and a clean production method thereof. The hexazinone-diuron original medicine water-dispersible granule comprises a hexazinone original medicine, a diuron original medicine, an auxiliary agent, a carrier filler and water, wherein the content of hexazinone is 12-15%, the content of diuron is 40-48%, and all the raw materials are commercially available commodities. The clean production method comprises three steps, namely wet-process negative-pressure mixing, negative-pressure fineness crushing and negative-pressure spray granulation. The continuous clean production method of the water-dispersible granule adopts closed production in the whole process of spray drying after whole-process negative-pressure and wet-process crushing, so compared with an intermittent water-dispersible pesticide granule production line, production links are reduced, a pesticide is finer, the use efficiency of the pesticide is higher, no pesticide dust overflows, loss is greatly reduced, the production cost can be reduced, environmental pollution caused by pesticide dust and waste gas in a production process can be effectively reduced, the environmental cleanliness of a production environment is improved, the occupational health of workers can be well protected, and the utilization rate of powder can be improved.

Description

Technical field: [0001] The invention relates to a production method of an agricultural herbicide, in particular to a clean production method of hexazinone and diuron water-dispersible granules. Background technique: [0002] Both the existing hexazinone and diuron water-dispersible granules adopt the production process of the batch production line, the quality of the produced products is unstable, the production cost is high, and the amount of three wastes is generated. To get a fundamental solution, it is necessary to find suitable production process conditions, production equipment and corresponding control means to reduce costs and improve product quality stability. Invention content: [0003] The invention provides a water-dispersed granule of hexazinone and diuron original medicine and a clean production method thereof. [0004] The technical scheme that the present invention takes is as follows: [0005] A water-dispersible granule of the original medicine of hexa...
