Abstract

MéTODO DE APERFEIçOAMENTO DA RESISTêNCIA AO ESMAGAMENTO E REDUçãO DA FORMAçãO DE Pó E DA TENDêNCIA DA URéIA DE FORMAR GRUMOS, E COMPOSIçãO DE URéIA. A invenção se refere a um método de aperfeiçoamento da resistência ao esmagamento e redução da formação de pó e da tendência de formação de grumos de partículas de uréia através da adição de um composto orgânico à uréia fundida, onde pelo menos um carboidrato e opcionalmente um composto polivinílico são adicionados à uréia. A invenção também se refere a uma composição a ser usada como um aditivo para uréia.
