Abstract

Procédé d'enrobage de matières actives susceptibles de se dissoudre rapidement dont on cherche à réduire la vitesse de libération caractérisé en ce que l'enrobage est réalisé par compactage d'un mélange de particules solides de matière active et de particules solides d'une matière pseudoplastique. Application particulièrement à la fabication d'engrais inorganiques à libération lente.Method for coating active materials capable of dissolving rapidly, the aim of which is to reduce the speed of release, characterized in that the coating is carried out by compacting a mixture of solid particles of active material and solid particles of a material pseudoplastic. Application particularly to the production of slow-release inorganic fertilizers.
