Abstract

ARENA AGLOMERADA DE RESINA FENOLICA CURADA DE ESTER, RECUPERADA DE DESGASTE O ROCE, SE SOMETE A TRATAMIENTO TERMICO ANTES DE UN NUEVO USO. CON ANTERIORIDAD AL TRATAMIENTO TERMICO, NO OBSTANTE, LA ARENA RECUPERADA DE DESGASTE SE HACE CONTACTAR CON UN ADITIVO QUE CONVIERTE LOS COMPUESTOS POTASICOS A UNA FORMA QUE TIENE UN PUNTO DE FUSION INFERIOR A 550 C, Y EL TRATAMIENTO TERMICO SE REALIZA A UNA TEMPERATURA INFERIOR A AQUELLA EN LA QUE SE FUNDE EL COMPUESTO RESULTANTE DE POTASIO.
