Abstract

COMPRENDE: PROVEER UNA PLURALIDAD DE LAMINAS TEJIDAS, UNIDAS EN UNA RELACION CARA A CARA TENIENDO DICHA PLURALIDAD DOS SUPERFICIES OPUESTAS. DICHAS SUPERFICIES TIENEN POROS DE DIFERENTE TAMANO, LOS CUALES AUMENTAN MONOTONICAMENTE DESDE LA PRIMERA SUPERFICIE EXPUESTA HACIA LA SEGUNDA SUPERFICIE EXPUESTA. DICHOS POROS SON LOS ORIFICIOS LIMITADORES EN LA CIRCULACION DE AIRE QUE SE UTILIZAN EN EL PROCESO DE SECAR Y SON TRATADOS PARA REDUCIR LA CAIDA DE PRESION EN ESTADO HUMEDO. DICHO TRATAMIENTO COMPRENDE LA APLICACION DE UNA CAPA EN LA SUPERFICIE, LA CUAL REDUCE LA ENERGIA SUPERFICIAL DE DICHOS POROS. DICHA REDUCCION ES DE 20% (1.5 PULGADAS DE HG) A UNA VELOCIDAD DE CIRCULACION PREDETERMINADA, LA CUAL ESTA ENTRE 40 Y 80 PIES CUBICOS ESTANDAR POR MINUTO POR 0.087 PIES CUADRADOS
