Description
(54) СОСТАВ ДЛЯ ОБРАБОТКИ МОЧЕВИНЫ(54) COMPOUND UREA TREATMENT
1one
Изобретение относитс к производству минеральных удобрений и может быть нспользовано при получении добавки, после обработки которой мочевина становитс прттодной дл безтарной транспортировки н хранени .The invention relates to the production of mineral fertilizers and can be used in the preparation of an additive, after the treatment of which urea becomes a prototype for non-containerized transportation and storage.
Известен состав дл обработки мочевины, состо щий из 80% сульфата аммони н 20% мочевины 1.A composition for treating urea is known, consisting of 80% ammonium sulfate and 20% urea 1.
Однако сыпучесть обработанных такой добавкой транул мочевнны высока н при транспортировке их навалом наблюдаютс большие потери удобрени . Кроме того, обработанна такой добавкой мочевина про вл ет при хранении навалом сильную слежнваемость.However, the flowability of transects treated with such an additive is urea high and in bulk transport, large losses of fertilizer are observed. In addition, urea treated with such an additive exhibits strong densification during bulk storage.
Наиболее близкой по составу к изобретению вл етс состав дл обработки мочевины полученный на основе минерального масла 12The closest in composition to the invention is the composition for the treatment of urea obtained on the basis of mineral oil 12
При хранении навалом в течение 9 мес. мочевины, обработанной минеральным маслом, она слеживаетс , так как минеральное масло проникает в гранулы.When stored in bulk for 9 months. for urea treated with mineral oil, it coagulates as the mineral oil penetrates into the granules.
Дл уменьшени слеживаемости мочевины предлагаемый состав дополнительно содержит битум при следующих соотношени х, вес.%:In order to reduce caking of the urea, the proposed composition additionally contains bitumen at the following ratios, wt%:
Минеральное масло60-95Mineral oil 60-95
Битум5-40Bitum5-40
Кроме того, в качестве битума используют битум, растворимый в минеральном масле и получаемый при переработке нефти, такой, как высоковакуумный битум или продутый битум, а также осветленный горный воск.In addition, bitumen is used as bitumen, which is soluble in mineral oil and is obtained during the processing of oil, such as high-vacuum bitumen or blown bitumen, as well as clarified mountain wax.
Добавку указанного состава ввод т в количестве 0,2-1,0% от веса мочевнны в расплав мочевины или путем опрыскивани гранулы мочевниы .The additive of this composition is introduced in an amount of 0.2-1.0% by weight of the urea into the urea melt or by spraying the urea granule.
Пример 1. В центрифугу одновременио в течение 1 ч подают 12 т расплава мочевины н 60 кг раствора, состо щего из. 80 вес.% минерального масла и 20 вес.% &1тумов.Example 1. 12 t of urea melt and 60 kg of a solution consisting of are fed to a centrifuge at the same time for 1 h. 80 wt.% Mineral oil and 20 wt.% &Amp; 1 ton.
Получаемь1е подобным образом гранулы мочевины имеют в среднем размер 1,0 мм. При хранении иавалом высотой 2 м после 12 мес. не было установлено слеживаемости продукта.In a similar way, urea granules have an average size of 1.0 mm. When stored at a height of 2 m after 12 months. no caking of the product has been established.
Пример 2. Гранулированную мочевину со средним размером гранул 1,5 мм непосредственно после ее изготовлени опрыскивают раствором из 10 вес.% битумов в г пгаеральном масле (раствор берут в количестве 0,3% от массы использованной мочевины). Температура гранул мочевины составл ла 50-60°С. При хранении навалом высотой 2 м после 12 мес. ие бьто установлено слеживаемости продукта. Сравнительные .данные по слеживаемости мочевины при хранении ее навалом в течение 9 мес. представлены в таблице.Example 2. Granulated urea with an average granule size of 1.5 mm is sprayed immediately after its manufacture with a solution of 10 wt.% Bitumen in g pheeral oil (the solution is taken in an amount of 0.3% by weight of the used urea). The temperature of the urea granules was 50-60 ° C. When stored in bulk with a height of 2 m after 12 months. It is established that the product is being cached. Comparative data on caking of urea when stored in bulk for 9 months. presented in the table.
