Abstract

LA PRESENTE INVENCION DESCRIBE UN PROCEDIMIENTO Y UN APARATO PARA FABRICAR ESTRUCTURAS ABSORBENTES QUE PRESENTAN UNA CAPA DE MATERIAL ABSORBENTE EN PARTICULAS DISCRETAS QUE ESTA DIVIDIDA EN DOS O MAS BANDAS (9) SEPARADAS POR UNA ZONA SUSTANCIALMENTE EXENTA DE PARTICULAS (11). EL PROCEDIMIENTO DE FABRICACION DE DICHAS ESTRUCTURAS ABSORBENTES INCLUYE LAS ETAPAS DE GENERAR EN PRIMER LUGAR UNA SUSPENSION DE PARTICULAS INICIAL QUE INCLUYE UN FLUIDO DE DOS FASES DE PARTICULAS DE MATERIAL GELIFICANTE ABSORBENTE, SUSPENDIDO EN UN GAS (TAL COMO AIRE) QUE FLUYE EN UN CONDUCTO DE ENTRADA. ENTONCES LA SUSPENSION DE PARTICULAS INICIAL SE DIVIDE EN MULTIPLES SUSPENSIONES DE PARTICULAS FINALES EN LOS CORRESPONDIENTES MULTIPLES CONDUCTOS RAMIFICADOS, PRESENTANDO CADA UNA DE LAS SUSPENSIONES DE PARTICULAS FINALES UN PORCENTAJE DADO DE PARTICULAS COMO FUNCION DEL AREA DE LA SECCION TRANSVERSAL DEL CONDUCTO DE ENTRADA. LAS PARTICULAS EN LAS SUSPENSIONES DE PARTICULAS FINALES SE DISTRIBUYEN DE FORMA SUSTANCIALMENTE UNIFORME COMO FUNCION DE LA POSICION EN LA SECCION TRANSVERSAL EN LOS CONDUCTOS RAMIFICADOS. FINALMENTE, LAS PARTICULAS SUSPENDIDAS SE FILTRAN DESDE LAS SUSPENSIONES DE PARTICULAS FINALES MEDIANTE SU CAPTURA SOBRE UN SUSTRATO, TAL COMO UN CAPA DE TEJIDO. UN APARATO SEGUN LA PRESENTE INVENCION PARA PRACTICAR EL ANTERIOR PROCEDIMIENTO INCLUYE UN CONDUCTO DE ENTRADA, UN GENERADOR DE UNA SUSPENSION DE PARTICULAS EN COMUNICACION DE FLUIDOS CON EL CONDUCTO DE ENTRADA PARA GENERAR LA SUSPENSION DE PARTICULAS INICIAL, AL MENOS DOS CONDUCTOS RAMIFICADOS EN COMUNICACION DE FLUIDOS CON EL CONDUCTO DE ENTRADA, Y UN DIVISOR DE LA SUSPENSION DE PARTICULAS DISPUESTO DENTRO DEL CONDUCTO DE ENTRADA PARA DIVIDIR LA SUSPENSION DE PARTICULAS INICIAL EN MULTIPLES SUSPENSIONES DE PARTICULAS FINALES EN LOS CONDUCTOS RAMIFICADOS. EN UNA REALIZACION PREFERIDA, EL APARATO INCLUYE ADEMAS UN DISPOSITIVO DE DISTRIBUCION DE ADHESIVO PARA REVESTIR DE FORMA ADHESIVA LAS PARTICULAS EN LAS SUSPENSIONES DE PARTICULAS FINALES PARA FORMAR PARTICULAS REVESTIDAS DE FORMA ADHESIVA.
