(FR) ENGRAIS DE TYPE MATRICE A LIBERATION REGULEE ET SON PROCEDE DE PREPARATION
Abstract
(EN)
The invention relates to the novel matrix coating fertilizer, and the process of preparation therefor, wherein the biodegradable coating materials, such as rosin, wax, aliphatic polyesters or the like, are mixed and melted slowly into liquid state, the particles of the fertilizer are added and mixed, the mixed coating materials and the particles of the fertilizer are extruded through the extruder and consequently the particles of the fertilizer are coated with matrix resin. The matrix-type fertilizer of the present invention has reduced the releasing rate of the fertilizer and the prices thereof are very economical since the matrix-type fertilizer of the present invention can be produced by a simple process.
(FR)
L'invention concerne un nouvel engrais à enrobage matriciel, ainsi que son procédé de préparation, consistant à mélanger les matières d'enrobage biodégradables, telles que de la colophane, de la cire, des polyesters aliphatiques ou analogues, et à les faire fondre lentement jusqu'à obtention d'un état liquide, à ajouter et à mélanger les particules de l'engrais, à extruder les matières d'enrobage ainsi que les particules d'engrais mélangées à travers l'extrudeuse, puis à enrober les particules de l'engrais avec une résine matricielle. L'engrais de type matrice de la présente invention a permis de réduire la vitesse de libération dudit engrais et ses coûts sont très économiques, étant donné que ledit engrais de type matrice de la présente invention peut être produit selon un procédé simple.
