Abstract

PROCEDIMIENTO DE AGLOMERADO DE ARIDOS CON CATALIZADOR CONSTITUIDO POR UN PRODUCTO ACIDO NEUTRALIZADO CON UNA BASE QUE TIENE UNA TENSION DE VAPOR UN PRODUCTO ACIDO NEUTRALIZADO CON UNA BASE QUE TIENE UNA TENSION DE VAPOR BAJA A LA TEMPERATURA DE TRABAJO. DICHA BASE BLOQUEA O INACTIVA AL CATALIZADOR HASTA EL INSTANTE EN QUE ES ELIMINADO POR VACIO; UNA VEZ DESBLOQUEADO EL CATALIZADOR SE PRODUCE LA REACCION DE POLIMERACION DEL AGLOMERANTE. EL AGLOMERANTE ESTA CONSTITUIDO POR RESINAS PURAS O MODIFICADAS CON OTRAS, PREFERENTEMENTE RESINAS FENOLICAS MODIFICADAS CON ALCOHOL FARFURICO Y CON CONTENIDO DE AGUA INFERIOR AL 5 POR 100. ESTE PROCEDIMIENTO ES DE EMPLEO EN FUNDICION.
