Abstract
Išradimas priklauso skystųjų trąšų gamybos sričiai ir gali būti panaudotas trąšų pramonėje gaminant skystąsias magnio nitrato trąšas. Išradimo esmė: dviejų rūšių skystosios magnio nitrato trąšos gautos paprastesniu būdu iš mažesnės koncentracijos (32 - 40)% azoto rūgšties vandeninio tirpalo ir magnezito, jį skaidant žemesnėje temperatūroje, kuriose yra didesnė (nuo 36,2 % iki 41,5 %) koncentracija magnio nitrato, o jų maisto medžiagų augalams sudėtis yra (6,85 - 7,85) % azoto ir (9,79 - 11,22) % magnio oksido. Šios trąšos gaunamos taip: magnezitas, kurio sudėtyje yra ne mažiau kaip 86 % magnio oksido, 1,0 val. - 2,0 val. skaidomos azoto rūgšties vandeniniu tirpalu iki 70 oC temperatūroje, gautas reakcijos mišinys maišomas 1 val., po to skaidymo tirpalas standartizuojamas magnezitu iki pH 4, maišomas 2 val. ir paliekamas nusistovėti ne mažiau kaip 15 val. Po nusistovėjimo dekantavimo būdu atskiriamas nuo nuosėdų pirmasis produktas suspensinės magnio nitrato trąšos (pH 4-7,5), kurios gali būti naudojamos augalams papildomai tręšti laistant. Filtruojamos nuosėdos arba nuosėdos ir magnio nitrato suspensija, gaunamas antrasis produktas - skystosios magnio nitrato trąšos, kurios atitinka hidroponikos reikalavimus ir gali būti naudojamos įvairiose laistymo bei drėkinimo sistemose bei gaminant skystųjų trąšų mišinius. Gautose trąšose yra didesnis magnio kiekis, jos gautos paprastesniu būdu ir kuriuo mažiausia žalingų azoto oksidų išgaravimo tikimybė. The invention relates to the field of liquid fertilizer production and can be used in the fertilizer industry to produce liquid magnesium nitrate fertilizers. BACKGROUND OF THE INVENTION: Two types of liquid magnesium nitrate fertilizer are obtained in a simpler manner from a lower concentration (32-40%) by weight of aqueous nitric acid and magnesite by decomposition at lower temperatures with higher concentrations (from 36.2% to 41.5%) of magnesium. the composition of their nutrients in plants is (6.85 - 7.85)% nitrogen and (9.79 - 11.22)% magnesium oxide. The following fertilizers are obtained: magnesite containing at least 86% magnesium oxide, 1.0 h. - 2.0 h The resulting reaction mixture was stirred for 1 h, then the decomposition solution was standardized with magnesite to pH 4 with stirring for 2 h. and left to stand for at least 15 hours. After settling, the first product, suspension magnesium nitrate fertilizer (pH 4-7.5), which can be used for additional fertilization of plants, is separated from the sediment by decantation. Filtration of sediment or suspension of sediment and magnesium nitrate yields a second product of liquid magnesium nitrate fertilizers that meet hydroponics requirements and can be used in a variety of irrigation and irrigation systems and in the production of liquid fertilizer mixtures. The resulting fertilizer has a higher magnesium content, is obtained in a simpler way and has the lowest chance of damaging the harmful oxides of nitrogen.
