Abstract

SE DESCRIBE UN METODO PARA FABRICAR PEQUEÑAS ESFERAS HUECAS DE VIDRIO, QUE SON PREPARADAS MEDIANTE LA ADICION DE UN SURFACTANTE A UNA MEZCLA PRECURSORA DE VIDRIO LIQUIDO. LA SOLUCION O DISPERSION SE PUEDE FORMAR EN GOTAS QUE ESTAN DIRIGIDAS A UNA ZONA CALENTADA Y LOS PRODUCTOS SON COLECTADOS EN UNA ZONA DE REFRIGERACION. ALTERNATIVAMENTE, LA SOLUCION O DISPERSION PUEDE SER SECADA POR MEDIO DE ROCIADO Y EL PRODUCTO SECO ES ALIMENTADO A LA ZONA CALENTADA Y RECOLECTADO EN LA ZONA DE ENFRIAMIENTO. LOS SURFACTANTES PREFERIDOS SON FRUOROCARBONADOS NO-IONICOS.
