Abstract

Procedimiento para la preparación de partículas de percarbonato sódico que constan de un núcleo de percarbonato sódico y de una envolventa a base de un silicado sódico y percarbonato sódico y/o tripolifosfato sódico, caracterizado porque el núcleo de percarbonato sódico se envuelve una o varias veces mediante una secuencia de "humedecimiento y recubrimiento", de tal manera que dicho núcleo se humedece primero con una solución de silicato y a continuación se recubre con polvo de percarbonato sódico y/o con tripolifosfato sódico.
