Abstract
Un Método y aparato para elaborar un hoja adherente de material poliméricoformadores de hidrogel absorbente sustancialmente insolubles en aguasformadas de partículas. El método comprende los pasos de colocación encapas en forma continua de partículas de gelación absorbentes secas sobreun transportador. Las partículas son luego rociadas con un mezcla líquida,la cual es una solución de agua y un agente de reticulación para lospolímeros en material formado de partículas. La cantidad rociada es lasuficiente para causar una reticulación eficaz de la superficie delmaterial formado de partículas después de curar la hoja. Los pasos decolocación en capas y rociado se pueden luego repetir varias veces si sedesea. Se aplicas luego presión al material formado de partículaspasándolo a través de un par de rodillos de compactación. El aparatocomprende un transportador a un más alimentadores para colocar en capaslas partículas de gelación absorbentes secas sobre el transportador, uno omás rociadores para rociar las partículas encima del transportador con unamezcla líquida t un par de rodillos de compactación.
