Abstract

QUE COMPRENDE: UN MEDIO MICROPOROSO PARA SER USADO CON UN APARATO DE SECADO POR CIRCULACION DE AIRE PARA HACER PAPEL; DICHO MEDIO 12997TIENE UN TAMANO DE PORO INFERIOR O IGUAL A 20 MICRONES Y UNA CAIDA DE PRESION A TRAVES DE LA MISMA; DICHA CAIDA DE PRESION AUMENTA CON EL AUMENTO DE LA VELOCIDAD DE CIRCULACION A TRAVES DE LA MISMA; LA CAIDA DE PRESION ESTA RELACIONADA A LA VELOCIDAD DE CIRCULACION POR LA FORMULA GENERAL: Y<0,048X+2,215 EN DONDE "X" ES LA VELOCIDAD DE CIRCULACION EN PIE CUBICO ESTANDAR POR MINUTO POR 0,087 PIE CUADRADO E "Y" ES LA CAIDA DE PRESION EN ESTADO HUMEDO EN PULGADAS DE MERCURIO. DICHA CAIDA DE PRESION EN ESTADO HUMEDO RELATIVAMENTE BAJA REDUCE VENTAJOSAMENTE LOS COSTOS DE ENERGIA QUE SE UTILIZAN EN EL PROCESO DE SECAR. Y UN PROCESO PARA HACER PAPEL TISU QUE COMPRENDE: A) PROVEER UNA TELA EMBRIONICA; B) PROVEER UN MEDIO MICROPOROSO; C) DISPONER LA TELA EMBRIONICA EN EL MEDIO MICROPOROSO; PASANDO AIRE A TRAVES DE LA TELA EMBRIONICA Y EL MEDIO MICROPOROSO, POR LO CUAL DICHO MEDIO ES UN ORIFICIO LIMITADOR PARA LA CIRCULACION DE AIRE A TRAVES DE DICHA TELA; Y D) REMOVER LA TELA EMBRIONICA DEL MEDIO MICROPOROSO
