Abstract

Przedmiotem wynalazku jest sposób otrzymywania otoczkowanego, saletrzanego nawozu granulowanego na bazie azotanu amonu o spowolnionym uwalnianiu, charakteryzujący się tym, że gotowy, granulowany nawóz na bazie azotanu amonu otrzymany na istniejącej instalacji pokrywa się, w kolejnym etapie, w złożu fluidalnym o temperaturze natrysku 30°C—60°C dyspersją polimeru lub polimerów biodegradowalnych, gdzie dyspersja stanowi połączenie wody, rozpuszczalnika organicznego, polimeru lub polimerów biodegradowalnych surfaktantu oraz stabilizatora pH.The subject of the invention is a method for obtaining coated, ammonium nitrate-based, slow-release granulated fertilizer, characterized in that the finished, granulated fertilizer based on ammonium nitrate obtained in an existing installation is coated, in the next stage, in a fluidized bed at a spray temperature of 30°C—60°C with a dispersion of biodegradable polymer or polymers, where the dispersion is a combination of water, an organic solvent, a biodegradable polymer or polymers, a surfactant and a pH stabilizer.
