Abstract
Mejoras introducidas en el objeto de la patente principal nº 453.026 concedida el 19 de Julio de 1977 por: ¿Un procedimiento para la fabricación de perborato sódico monohidratado al estado de gránulos resistentes a la abrasión¿, en el que se introducen simultáneamente una solución acuosa que contiene peróxido de hidrógeno, y una solución acuosa que contiene metaborato sódico, en un secador de lecho fluido que contiene gérmenes de dimensiones inferiores a las de los gránulos que se desea obtener, y se evapora el excedente de agua presente en dichas soluciones acuosas, mediante gas de fluidización que se introduce en el secador de lecho fluido, caracterizadas dichas mejoras porque se introduce al menos un agente tensioactivo en al menos una de las soluciones acuosas que contienen peróxido de hidrógeno y metaborato sódico.
