Abstract

LA INVENCION SE REFIERE A CIGARRILLOS DE SALIDA BAJA, QUE NORMALMENTE TIENEN UNA SALIDA DE MATERIA PARTICULADA DE LINEA PRINCIPAL DE 9MG O MENOS. LOS CIGARRILLOS (1) CONSTAN DE UNA VARILLA DE TABACO Y UN ELEMENTO FILTRANTE (3). EL ELEMENTO FILTRANTE (3) COMPRENDE UNA SECCION DE MATERIAL FILTRANTE ALCALINO (4) QUE TIENE UN NIVEL DE CARGA INFERIOR AL 12% DEL PESO DE LA SECCION. LAS CARACTERISTICAS DE LOS CIGARRILLOS (1) ESTAN DISPUESTAS DE TAL FORMA QUE, CUANDO SE FUMA, EL MATERIAL FILTRANTE ALCALINO ES EXPUESTO A UNA CANTIDAD DE HUMO ACEPTABLE PARA LOGRAR UNA PERCEPCION AUMENTADA DEL IMPACTO DEL HUMO. NORMALMENTE, ESTO SE LOGRA UTILIZANDO UNA VARILLA POTENCIAL DE MATERIA PARTICULADA BAJA. DE ESTA FORMA, LA MATERIA PARTICULADA SECA LIBRE DE HUMEDAD (NFDPM) PARA EL INDICE DE NICOTINA SE REDUCE EN COMPARACION CON CIGARRILLOS DE CONTROL QUE TIENEN LAS MISMAS CARACTERISTICAS SIN LA ADICION DEL MATERIAL FILTRANTE ALCALINO AL ELEMENTO FILTRANTE.
