Abstract
UN MATERIAL DE FILTRADO EXTRUIDO EL CUAL ES DEGRADABLE Y COMPRENDE BIEN UN MATERIAL PLASTICO, O BIEN UN MATERIAL INORGANICO QUE TIENE UN PUNTO DE FUSION POR ENCIMA DE LA TEMPERATURA DE OPERACION, UN MEDIO DE EXPANSION POLISACARIDO, UN PEGAMENTO Y AGUA. ESTOS INGREDIENTES SON ALIMENTADOS A UN EXTRUSOR Y SOMETIDOS A UN PROCESO DE EXTRUSION EL CUAL INCLUYE UNA REDUCCION DE PRESION DE EXTRUSION SOBRE LA BOQUILLA DE SALIDA, DE HASTA ALREDEDOR DE 70 BARES, DE MODO QUE SE PRODUZCA EL HINCHADO DEL EXTRUIDO PARA DAR UNA ESTRUCTURA CELULAR. CUANDO SE EXPONE A CONDICIONES AMBIENTES NATURALES EL TABACO, RESTOS DE HUMO, ELEMENTOS QUE COMPONEN TALES MATERIALES, SE DEGRADAN SIN DEJAR UNA AMALGAMA FUSIONADA DE PLASTICOS O MATERIALES INORGANICOS.
