Abstract

LOS GRANULADOS PUEDEN FABRICARSE DE POLVO DE SUSTANCIA ACTIVA POR TUBULENCIA EN LA CORRIENTE DE AIRE Y PULVERIZACION DE UNA DISOLUCION ADHESIVA SEGUN EL PRINCIPIO DE CONTRACORRIENTE. SEGUN EL INVENTO PUEDEN GRANULARSE DISPERSIONES O DISOLUCIONES DE SUSTANCIA ACTIVA CUANDO LA DISPERSION O DISOLUCION ACUOSA SE PUEDE PULVERIZAR Y REALINEAR SEGUN EL PRINCIPIO DE CONTRACORRIENTE EN LA CORRIENTE DE GAS DE UNA CAMARA TURBULENTA, CON LO QUE EN UNA FASE DE PARTIDA LA FORMACION DE GRANULADO SE COMIENZA CON EL 10 AL 60% DE PORCENTAJE MAXIMO DE ALIMENTACION EN DISPERSION O DISOLUCION Y CONSECUTIVAMENTE EL PORCENTAJE DE ALIMENTACION Y DE LA CORRIENTE DE GAS SE ELEVA HASTA LOS MAXIMOS VALORES DEL PORCENTAJE DE ALIMENTACION Y DE CORRIENTE DE GAS Y EN LA FASE PRINCIPAL SE PROSIGUE LA FORMACION DE GRANULADO EN LA MAXIMA CORRIENTE DE GAS Y MAXIMO PORCENTAJE DE ALIMENTACION. LOS GRANULADOS FABRICADOS DE ESTA FORMA, QUE CONTIENE PESTICIDA COMO SUSTANCIA ACTIVA, SE UTILIZAN COMO MEDIOS DE PROTECCION DE PLANTAS O LUCHA CONTRA ANIMALES DAÑINOS
