Abstract

UN PROCEDIMIENTO PARA EL TRATAMIENTO DE POLIMEROS DE POLIURETANO, POLIURETANO/UREA Y POLIUREA MOLDEADOS POR INYECCION Y REACCION QUE CONSISTE EN EXPONER UN POLIMERO DE POLIURETANO, POLIURETANO/UREA O POLIUREA MOLDEADO POR INYECCION Y REACCION A UNA CANTIDAD DE ENERGIA INFRARROJA SUFICIENTE PARA AUMENTAR LA TEMPERATURA DEL POLIMERO A 180 C POR LO MENOS Y MANTENER A CONTINUACION LA TEMPERATURA DEL POLIMERO A O POR ENCIMA DE ESA TEMPERATURA, DURANTE UN TIEMPO SUFICIENTE PARA AUMENTAR LA RESISTENCIA AL CHOQUE DE GARDNER, MEDIDO SEGUN LA ASTMD-3029, EN COMPARACION CON EL MISMO POLIMERO QUE HA SIDO CALENTADO A LA MISMA TEMPERATURA Y MANTENIDO A LA MISMA DURANTE EL MISMO TIEMPO EN UN HORNO DE CONVECCION. CON LA INVENCION SE OBTIENEN MEJORAS NOTABLES EN CUANTO A LAS PROPIEDADES DE CHOQUE, PANDEO TERMICO Y TEMPERATURA DE TERMODISTORSION Y POR TANTO ES PARTICULARMENTE ADECUADA EN LA PREPARACION RAPIDA DE PIEZAS UTILIZANDO UN TRANSPORTADOR DE PRODUCCION EN MASA Y ES SOBRE TODO ADECUADA PARA LA PREPARACION DE PIEZAS A LAS QUE SE VA A SOMETER POSTERIORMENTE A PROCEDIMIENTOS A ALTA TEMPERATURA, TAL COMO EL PROCEDIMIENTO DE "ENLUCIDO TIPO E".
