Abstract

SE SUMINISTRA UN METODO PARA ELIMINAR LAS PARTICULAS QUE SE ADHIEREN ELECTROSTATICAMENTE A LAS PASTILLAS DE RESINA SINTETICA DE UNA MEZCLA DE PASTILLAS DE RESINA SINTETICA QUE CONTENGAN LAS PARTICULAS FINAS, EL METODO COMPRENDE LA PUESTA DE LA MEZCLA EN CONTACTO CON UN GAS QUE HAYA SIDO EXPUESTO A UN TRATAMIENTO DE IONIZACION PARA ELIMINAR LA ADHESION ELECTROSTATICA ENTRE LAS PASTILLAS DE RESINA SINTETICA Y LAS PARTICULAS FINAS, Y LA SEPARACION DE LAS PARTICULAS FINAS RESULTANTES EN LAS QUE SE HAN ELIMINADO LA MENCIONADA ADHESION. DE ACUERDO CON EL METODO, SE ELIMINAN EFICIENTEMENTE LAS PARTICULAS FINAS QUE SE ADHIEREN ELECTROSTATICAMENTE A LAS PASTILLAS DE RESINA SINTETICA. TAMBIEN SE SUMINISTRAN DOS TIPOS DE APARATOS PARA PRACTICAR EL METODO ANTES MENCIONADO Y UN HABITACULO DE ALMACENAMIENTO DE PASTILLAS DE RESINA SINTETICA EQUIPADO CON CUALQUIERA DE LOS APARATOS MENCIONADOS.
