Abstract

PROCESO PARA LA PRODUCCION DE UNA ESPUMA DE POLIURETANO DE CELULAS ABIERTAS QUE COMPRENDE EL MEZCLADO DE LOS SIGUIENTES COMPONENTES A TEMPERATURAS AMBIENTE EN LA ZONA DE MEZCLADO: UN DIISOCIANATO CON UNA FUNCIONALIDAD DE, AL MENOS, 2,0 APROXIMADAMENTE, AL MENOS UN DADOR DE HIDROGENO, AL MENOS UN SURFACTANTE EFECTIVO EN LA FORMACION DE ESPUMA DE POLIURETANO DE CELULAS ABIERTAS, AL MENOS UN CATALIZADOR Y UN AGENTE DE SOPLADO QUE COMPRENDA UN GAS QUE TENGA UN PUNTO DE EBULLICION INFERIOR APROXIMADAMENTE A -100 (GRADOS) F A TEMPERATURA Y PRESION ATMOSFERICAS QUE CONTENGA PREFERIBLEMENTE DIOXIDO DE CARBONO. ADEMAS, LA MEZCLA TAMBIEN PUEDE CONTENER, OPCIONALMENTE, AGUA. LA MEZCLA ESTA SUJETA A UNA PRESION, EN DICHA ZONA DE MEZCLADO, SUFICIENTE PARA MANTENER EL AGENTE DE SOPLADO EN ESTADO LIQUIDO A TEMPERATURAS AMBIENTE. TRAS EL MEZCLADO, LA MEZCLA SE EXPULSA DE LA ZONA DE MEZCLADO A PRESION ATMOSFERICA, DE ESTE MODO SE EVAPORA COMPLETA E INSTANTANEAMENTE EL AGENTE DE SOPLADO PARA FACILITAR LA EXPANSION DE LA MEZCLA. LA ESPUMA RESULTANTE SE CURA A CONTINUACION A TEMPERATURAS AMBIENTE.
