FIELD: chemical industry.
SUBSTANCE: the invention is dealt with preparation of agricultural chemicals, mineral and other substances, in particular, with the methods of preparation of the in-water-dispersible granules containing the above substances. The method of preparation of a composition in the form of extruded granules and containing at least one acting component provides for adding in the composition before its extrusion at least one organosilicon surfactant. The amount of this organosilicon surfactant is taken within the interval from more than 0.001 up less than 0.1 mass % in turns of the mass of the composition before extrusion. The invention also offers a method of lowering temperature of the extrusion process of the extruded composition for agricultural usage by introduction of the indicated amount of the organosilicon surfactant and extruded granules in the initial composition and steering the mixture before the extrusion process. The invention allows to low temperature of realization of the extrusion process, that allows to make the process of an extrusion more efficient without loosening a biological effect of the acting component.
EFFECT: invention allows to low temperature of realization of the extrusion process and to make it more efficient without loosening a biological effect of the acting component.
