Abstract
Методът намира приложение в селското стопанство. Получават се гранули с висока устойчивост на удар и високо специфично тегло, които се използват като тор. Методът се състои в това, че към карбамидната стопилка или към водния карбамиден разтвор през време на гранулирането или на втвърдяването се прибавя като забавител на кристализацията магнезиев окис 0,5 2 % тегл., Изчислено спрямо карбамида в стопилката или в разтвора. Магнезиевият окис е под формата на прах и на частично или напълно калциниран доломит. Образуваните карбамидни гранули могат да се смесват със суперфосфат, с троен суперфосфат или с калиев хлорид.5 претенцииThe method finds application in agriculture. Granules with high impact resistance and high specific gravity are obtained, which are used as fertilizer. The method consists in that magnesium oxide 0.5 2% by weight, calculated relative to the urea in the melt or in the solution, is added as a crystallization retarder to the urea melt or to the aqueous urea solution during granulation or solidification. Magnesium oxide is in the form of powder and partially or fully calcined dolomite. The formed urea granules can be mixed with superphosphate, with triple superphosphate or with potassium chloride. 5 claims
