Abstract

PROCEDIMIENTO Y APARATO PARA FABRICAR MATERIAL CELULAR DE UREA-FORMALDEHIDO DE UTILIDAD COMO SORBENTE. CON ESTE PROCEDIMIENTO SE PRETENDE EVITAR LOS PROBLEMAS ASOCIADOS A LA DENSIDAD DEL SORBENTE; ESTO SE CONSIGUE MEDIANTE DEL SORBENTE; ESTO SE CONSIGUE MEDIANTE LA TRITURACION Y EMPAQUETADO EN RECIPIENTES HERMETICAMENTE CERRADOS O BOLSAS, CON LO QUE SE OBTIENEN UNA DENSIDAD HASTA DIEZ VECES MAYOR. EN UN APARATO (1) SE TRITURA EL MATERIAL DE UREA-FORMALDEHIDO (2) HASTA QUE TENGA UN DIAMETRO E 10 A 20 MM; EL MATERIAL TRITURADO SE HACE PASAR POR UN CONDUCTO TUBULAR (4) DE 10 M. DE LARGO Y 25 CM. DE DIAMETRO, DONDE SE PULVERIZA CON UN AGENTE TENSOACTIVO COMO UNA SOLUCION DE HIDROGENO FOSFATO DE DIAMONIO MEDIANTE UNAS TOBERAS (5) Y SE LE EMPAQUETA HERMETICAMENTE EN UN EMPAQUETADOR (6). DE USO PARA SORBER LIQUIDOS REDUCTORES DE LA FRICCION COMO ACEITE EN ESPACIOS ABIERTOS COMO CARRETERAS.
