Description

Technical Field

[0001] The utility model relates to the technical field of pesticide production, in particular to a suspension agent shearing and dispersing reaction kettle. Background Art

[0002] At present, there are relatively few types of pesticide formulations. Most of the formulations produced and used are suitable for spraying, among which emulsions and wettable powders are the main ones, and suspensions also have considerable production. The efficacy of insecticide emulsions is significantly higher than that of suspensions and wettable powders. For fungicides used for foliar sprays, the formulations with oil as the medium are generally not good for the fungicide effect, because the penetration of fungicides into the cell walls and cell membranes of pathogens is the penetration of fungicide molecules dissolved in the water film on the leaf surface, which does not require the assistance of oily organic solvents, and may even hinder the diffusion, penetration and systemic effect of the drug molecules. Therefore, it is advisable to choose suspensions or wettable powders. The particles of the suspension are It is much finer than wettable powder. The various additives contained in the suspension concentrate are beneficial for the drug particles to adhere to the surface of the organism, thereby improving the efficacy. However, because the particles of the suspension concentrate are smaller, it is more complicated to prepare during the production and processing. It needs to be prepared in a dedicated shear reactor to ensure that the particle size meets the standard. However, the existing shear reactor relies entirely on the stirring force to drive the solvent and the material to rotate during the stirring process. The uneven distribution of the materials in the upper and lower layers will result in a better dispersion effect of the materials in the upper layer, while the lower layer cannot be fully dispersed due to the large number of large particles, which makes the particle size of the suspension not meet the standard and affects the product quality.
