Abstract

PROCEDIMIENTO DE FABRICACION DE PRODUCTOS ACOLCHADOS DE ESPUMA DE POLIURETANO COLADO IN SITU EN UN ENVOLTURA TEXTIL, QUE COMPRENDE: DISPONER SUCESIVAMENTE EN UN MOLDE UN MATERIAL TEXTIL SOBRE EL CUAL ESTA APLICADA UNA HOJA DE ESPUMA DE CELULAS ABIERTAS Y COMUNICANTES, Y LUEGO UNA PELICULA DE COLA ESTANCA; ADHERIR POR SUCCION EL COMPLEJO RESULTANTE, DESTINADO A CONSTRUIR LA ENVOLTURA DEL PRODUCTO ACOLCHADO, SOBRE LA PARED INTERIOR DEL MOLDE; COLAR EN DICHO MOLDE UNA MEZCLA ESPUMANTE DE POLIURETANO QUE SE EXPANDE Y SE GELIFICA DESPUES DEL CIERRE DE DICHO MOLDE; Y FINALMENTE REALIZAR UNA MICROPERFORACION DE DICHA PELICULA DE COLA ESTANCA CALENTANDOLA HASTA SU ABLANDAMIENTO Y SOMETIENDOLA A EFECTO DE SUCCION, LO QUE LE CONFIERE BUENA PERMEABILIDAD AL VAPOR DE AGUA, PERMITIENDO IGUALMENTE GENERAR POR EL EFECTO DE SUCCION UNA DEPRESION EN LA ESPUMA QUE SE HALLA EN PROCESO DE GELIFICACION, QUE PROVOCA LA ROTURA DE SUS CELULAS DE MANERA QUE EL PRODUCTO ACOLCHADO DE ESPUMA RESULTANTE PRESE NTA DESPUES DE LA POLIMERIZACION Y EL DESMOLDEO, CELULAS CONSTITUTIVAS ABIERTAS Y COMUNICANTES.
