Abstract

SE EXPONE UN PROCEDIMIENTO PARA PREPARAR UN ARTICULO DE ESPUMA DE CAPAS MULTIPLES, POR EJEMPLO UN ASIENTO PARA AUTOMOVIL. UN MOLDE SE DISPONE DE MANERA QUE LA SUPERFICIE INFERIOR DEL MOLDE SEA PLANA O INCLINADA EN UN MAXIMO DE 40 GRADOS RESPECTO AL PLANO HORIZONTAL. LA PRIMERA FORMULACION DE ESPUMA LIQUIDA DISEÑADA PARA PRODUCIR UNA ESPUMA SUAVE SE VIERTE EN EL MOLDE DESDE UNA SALIDA DEL CABEZAL MEZCLADOR, EN FORMA DE TIRAS A TRAVES DE LA ZONA DEL ASIENTO DEL MOLDE, SIGUIENDO LA LINEA PARALELA A LA PARED EXTERIOR DE LA ZONA DEL MOLDE DEDICADA AL ASIENTO, PERO CERCA DE DICHA PARED. A CONTINUACION, SE VIERTE EN EL MOLDE LA SEGUNDA FORMULACION DE ESPUMA LIQUIDA DESTINADA A PRODUCIR UNA ESPUMA DURA A PARTIR DE LA MISMA SALIDA DEL CABEZAL MEZCLADOR O DE OTRA DIFERENTE, TAMBIEN EN FORMA DE TIRAS A TRAVES DE LA ZONA DEL ASIENTO DEL MOLDE, SIGUIENDO LA LINEA PARALELA A LA PARED EXTERIOR DEL MOLDE PERO MAS CERCANA QUE LA LINEA DE VERTIDO DE LA PRIMERA FORMULACION DE ESPUMA LIQUIDA. A CONTINUACION SEPERMITE QUE LA SEGUNDA FORMULACION DE ESPUMA LIQUIDA SE EXTIENDA ENCIMA DE LA PRIMERA FORMULACION DE ESPUMA LIQUIDA, SE CIERRA EL MOLDE Y SE DEJA QUE LAS ESPUMAS SUBAN Y SE ENDUREZCAN EN EL MOLDE. EL PROCEDIMIENTO PERMITE OBTENER UN ARTICULO QUE TIENE UNA EXCELENTE SUPERFICIE DE ASIENTO A BASE DE ESPUMA EN VARIAS CAPAS.
