Abstract

SE REFIERE A ESTRUCTURAS ABSORBENTES, QUE COMPRENDEN; A) UNA PRIMERA REGION PARA CAPTACION/DISTRIBUCION DE FLUIDOS QUE COMPRENDE MATERIALES QUE PUEDEN TENER UNA PRESION DE DESORCION CAPILAR RELATIVAMENTE ALTA, TAL COMO MATERIAL FIBROSO, UNA ESPUMA POLIMERICA Y SIMILARES. PRESENTANDO DICHA REGION UN FLUJO ACUMULATIVO DE MAS DE 0,075 g/cm²/seg A 12,4 cm DE ALTURA Y/O UN TIEMPO DE ESCURRIMIENTO MENOR A 120 seg A ESA ALTURA; Y B) UNA SEGUNDA REGION PARA ALMACENAMIENTO DE FLUIDOS QUE COMPRENDE MATERIALES, TALES COMO MATERIALES FORMADORES DE HIDROGEL,QUE EXHIBEN UNA PRESION DE ABSORCION CAPILAR SUFICIENTEMENTE ALTA, DE MODO QUE DRENE EFICIENTEMENTE LA PRIMERA REGION, DEBIENDO CUMPLIR DICHOS MATERIALES AL MENOS CON UNO DE LOS SIGUIENTES REQUISITOS: i) CAPACIDAD DE SORCION-ABSORCION CAPILAR A 35 cm (CSAC 35) DE POR LO MENOS 15 g/g; Y/O ii) CAPACIDAD DE SORCION-ABSORCION CAPILAR A 0 cm (CSAC 0) DE POR LO MENOS 15 g/g, Y EFICIENCIA DE SORCION-ABSORCION CAPILAR A 40 cm (CSAE 40) DE POR LO MENOS 55%; Y/O iii) ALTURA DE SORCION-ABSORCION CAPILAR, AL 50% DE SU CAPACIDAD Y A 0 cm DE ALTURA DE ABSORCION (CSAH 50), DE POR LO MENOS 35 cm. SE USAN COMO ESTRUCTURAS ABSORBENTES EN ARTICULOS ABSORBENTES, TALES COMO PANALES Y SIMILARESREFERS TO ABSORBENT STRUCTURES, WHICH INCLUDE; A) A FIRST REGION FOR COLLECTION / DISTRIBUTION OF FLUIDS THAT INCLUDES MATERIALS THAT MAY HAVE A RELATIVELY HIGH CAPILLARY DESORPTION PRESSURE, SUCH AS FIBROUS MATERIAL, A POLYMERIC FOAM AND THE LIKE. SAID REGION PRESENTING A CUMULATIVE FLOW OF MORE THAN 0.075 g / cm² / sec AT 12.4 cm HEIGHT AND / OR A DRAINING TIME LESS THAN 120 sec AT THAT HEIGHT; AND B) A SECOND REGION FOR FLUID STORAGE THAT INCLUDES MATERIALS, SUCH AS HYDROGEL-FORMING MATERIALS, WHICH EXHIBIT A SUFFICIENTLY HIGH CAPILLARY ABSORPTION PRESSURE, SO THAT THE FIRST REGION EFFICIENTLY DRAINS THE FIRST REGION, DUE TO THE LESS THAN MORE CONDITIONS. REQUIREMENTS: i) CAPILLARY SORPTION-ABSORPTION CAPACITY AT 35 cm (CSAC 35) OF AT LEAST 15 g / g; AND / OR ii) CAPILLARY SORTION-ABSORPTION CAPACITY AT 0 cm (CSAC 0) OF AT LEAST 15 g / g, AND CAPILLARY SORPTION-ABSORPTION EFFICIENCY AT 40 cm (CSAE 40) OF AT LEAST 55%; AND / OR iii) CAPILLARY SORPTION-ABSORPTION HEIGHT, AT 50% OF ITS CAPACITY AND AT 0 cm OF ABSORPTION HEIGHT (CSAH 50), OF AT LEAST 35 cm. THEY ARE USED AS ABSORBENT STRUCTURES IN ABSORBENT ARTICLES, SUCH AS PANELS AND THE LIKE
