Abstract

UN METODO PARA LA SEPARACION DE UNA MEZCLA DE PEDAZOS DE MATERIALES PLASTICOS EN CATEGORIAS DISTINTAS QUE INCLUYEN LOS SIGUIENTES PASOS: ESCANEAR UNA SUPERFICIE DE CADA PEDAZO CON RADIACION MEDIA DE INFRARROJOS, OBTENIENDO UN ESPECTRO DE REFLECTANCIA DE INFRARROJOS PARA LA SUPERFICIE, COMPARANDO EL ESPECTRO CON ESPECTROS DE REFERENCIA PARA IDENTIFICAR UNA CORRESPONDENCIA, Y COLOCANDO CADA PEDAZO EN UN CONTENEDOR CORRESPONDIENTE A SU CATEGORIA. EL INVENTO TAMBIEN ABARCA UN INSTRUMENTO PARA SU UTILIZACION EN EL METODO.
