Description
Изобретение относитс к -способам получени азотномагниевых удобрений на основе карбоната аммони и соли магни .This invention relates to methods for producing nitrogen-magnesium fertilizers based on ammonium carbonate and a magnesium salt.
Известен способ получени азотномагниевых удобрений на основе бикарбоната аммони , заключающийс в том, что влажный кристаллический бикарбонат аммони смешивают с MgNHiPOi бНаО или MgHPO4MgHPO4-3H20 либо с их смесью. При этом образуетс оболочка из MgNH4PO4 6Н2О, охран юща от выветривани аммиака карбонат аммони . Получаетс .продукт, содержащий 12-16,8% азота.A known method for producing ammonium bicarbonate-based nitrogen-magnesium fertilizers, which consists in mixing the wet crystalline ammonium bicarbonate with MgNHiPOi bNaO or MgHPO4MgHPO4-3H20 or with their mixture. In this case, a shell of MgNH4PO4 6H2O is formed, protecting ammonium carbonate from ammonia weathering. A product containing 12-16.8% nitrogen is obtained.
Педостатком этого способа получени удобрени вл етс сравнительна сложность изготовлени фосфорных соединений магни , а также мала растворимость в виде получаемых продуктов.The disadvantage of this method of producing fertilizer is the comparative complexity of the manufacture of magnesium phosphorus compounds, as well as the low solubility in the form of the products obtained.
С целью устранени недостатков и повыщени качества продукта предложен способ, в котором исходным продуктом вл етс обезвоженна соль двойного сульфата магни и аммони MgSO4(NH4)2SO4 - соль Туттона. Порощок этой соли смещивают с измельченным порощком карбоната аммони , и смесь затвор ют небольщим количествол воды (10- 25% от веса смеси). При этом смесь схватываетс и твердеет аналогично в жущим материалам , например гипсу. Процесс схватывани длитс недолго - всего 5-10 мин.In order to eliminate the drawbacks and increase the quality of the product, a method has been proposed in which the initial product is the dehydrated salt of magnesium and ammonium double sulfate MgSO4 (NH4) 2SO4 - Tutton salt. The powder of this salt is shifted with a crushed powder of ammonium carbonate, and the mixture is closed with a small amount of water (10-25% by weight of the mixture). In this case, the mixture seizes and hardens in a similar manner to the holding materials, for example gypsum. The process of setting does not last long - only 5-10 minutes.
Дл осуществлени процесса может бытьTo carry out the process can be
использован и порошок карбонатаused and carbonate powder
аммони . В этом случае количество воды затворени уменьшаетс в соответствии с количеством влаги в карбонате.ammonium. In this case, the amount of mixing water is reduced in accordance with the amount of moisture in the carbonate.
Получаемые гранулы обладают высокой прочностью и воздухоустойчивостью. Удобрение хорощо растворимо в воде, негигроскопично и не слеживаетс при храненИИ, поэтому удобно дл применени .The resulting granules have high strength and air resistance. The fertilizer is well soluble in water, non-hygroscopic and does not clog when stored, therefore it is convenient for use.
Химический состав получаемых удобрений может быть выражен суммарной формулой MgS04(NH4)2S04 т(тН4)2СОз-«ПоО; значени т vi п завис т от весовых соотнощений обезвоженной соли Туттона, карбоната аммони и воды в смеси. Практически т может прин ть значени от 1 до 10, а - от 6 до 12.The chemical composition of the obtained fertilizers can be expressed by the total formula MgS04 (NH4) 2S04 t (tH4) 2CO3 - “Poo; the values of t vi p depend on the weight ratios of the dehydrated Tutton salt, ammonium carbonate and water in the mixture. Practically, t can take values from 1 to 10, and - from 6 to 12.
Пример. Смешивают карбонат аммони , содержащий аммиака 31%, и обезвоженную соль Туттона, содержащую, %: MgO 15-20; SOs 64,76; NHs 12,81 в следующих весовых соотношени х комГонентоБ на 1 вес. ч. обезвоженной соли Туттона:Example.
