Abstract
LA INVENCION SE REFIERE A UN METODO ULTRASONICO, CONTINUO Y A UN APARATO PARA ROMPER LOS ENLACES CARBONO-AZUFRE (C-S), AZUFRE-AZUFRE (S-S), Y SI SE DESEA LOS ENLACES CARBONO-CARBONO (C-C) EN UN ELASTOMERO VULCANIZADO. ES BIEN CONOCIDO QUE LOS ELASTOMEROS VULCANIZADOS QUE TIENEN UNA RED QUIMICA TRIDIMENSIONAL, NO PUEDEN FLUIR BAJO EL EFECTO DEL CALOR Y/O LA PRESION. ESTO CREA UN PROBLEMA EN EL RECICLADO DE NEUMATICOS USADOS Y OTROS PRODUCTOS ELASTOMERICOS. A TRAVES DE LA APLICACION DE CIERTOS NIVELES DE AMPLITUDES ULTRASONICAS EN LA PRESENCIA DE PRESION Y OPCIONALMENTE CALOR, LA RED TRIDIMENSIONAL DEL ELASTOMERO VULCANIZADO PUEDE ROMPERSE. COMO CONSECUENCIA MAS DESEABLE, LA GOMA ULTRASONICAMENTE TRATADA SE VUELVE BLANDA, HACIENDO POSIBLE DE ESTA FORMA QUE ESTE MATERIAL SEA PROCESADO Y CONFORMADO DE FORMA SIMILAR A LA QUE SE EMPLEA CON OTROS ELASTOMEROS. EL APARATO SE REFIERE A UN REACTOR ULTRASONICO (20), POR EJEMPLO UN EXTRUSOR. EL REACTOR SE CONECTA A UN DISPOSITIVO DE TROQUEL ULTRASONICO(10); EL DISPOSITIVO DE TROQUEL CONSTA DE UNA PARTE TRANSDUCTORA (12), QUE INCLUYE UN CONVERSOR DE POTENCIA (14) Y UN ELEVADOR DE TENSION (13), CONECTADOS A UNA PARTE DE UNA BOQUILLA (15), EL DISPOSITIVO ESTA SOPORTADO POR UN SOPORTE DE MONTAJE (18), Y ESTA SUJETO AL REACTOR (20) A TRAVES DE UNA PARTE ADAPTADORA (19). EL REACTOR INCLUYE UN CILINDRO (22), ALIMENTADO CON UNA TOLVA (24), EL TORNILLO SINFIN (26) DENTRO DEL CILINDRO ES IMPULSADO POR UN DISPOSITIVO IMPULSOR (25), ALIMENTADO POR UN MOTOR (28) (NO MOSTRADO). LA PARTE DE LA BOQUILLA INCLUYE UN TROQUEL (16) A TRAVES DEL CUAL EL ELASTOMERO DESVULCANIZADO QUE ESTA SUFRIENDO EL PROCESO DE EXTRUSION ES FORZADO POR LA PRESION PROVOCADA POR UN DISPOSITIVO (21). EL GENERADOR ULTRASONICO DEL TROQUEL ULTRASONICO DE LA INVENCION, ESTA SUJETO DE FORMA MOVIL MEDIANTE EL SOPORTE DE MONTAJE (18) A TRAVES DE PATAS ADAPTADORAS (19) A UN REACTOR (20). EL REACTOR ESTA RODEADO POR UNA CAMISA DE CALENTAMIENTO (42). EL MATERIAL VULCANIZADO ES SUMINISTRADO AL INTERIOR DEL TROQUEL (16) A TRAVES DE UNA SALIDA (36) DEL REACTOR DE UN DIAMETRO DE ORIFICIO (DR) Y AL INTERIOR DEL ORIFICIO DE ENTRADA DEL TROQUEL (38) DE UN DIAMETRO (DI). EL MATERIAL VULCANIZADO SE MUEVE BAJO PRESION HACIA EL ORIFICIO DE SALIDA DEL TROQUEL (37) Y SALE A TRAVES DEL ORIFICIO DE ENTRADA (38).
