Abstract

SE REFIERE A UN PROCEDIMIENTO PARA LA PRODUCCION DE POLIURETANOS/ POLIUREAS, QUE SE REALIZA EN UNA FORMA OPERATIVA CONTINUA EN UN REACTOR, EL CUAL PRESENTA: A) UN CUERPO "A" QUE PRESENTA UNA SUPERFICIE CALIENTE QUE ROTA ALREDEDOR DE UN EJE DE ROTACION; B) UN SISTEMA DE DOSIFICACION; Y C) UN DISPOSITIVO DE ENFRIAMIENTO BRUSCO; DONDE: i) LOS COMPONENTES DE UNA COMPOSICION DE REACCION DE PARTIDA SE APLICAN SOLOS Y/O COMO MEZCLA CON AYUDA DEL SISTEMA DE DOSIFICACION EN UNA PELICULA FINA SOBRE UN AREA INTERNA DE LA SUPERFICIE CALIENTE DEL CUERPO EN ROTACION "A", DE MODO QUE LA PELICULA FINA FLUYE SOBRE LA SUPERFICIE CALIENTE DEL CUERPO EN ROTACION "A" HACIA UN AREA EXTERIOR DE LA SUPERFICIE CALIENTE DEL CUERPO EN ROTACION "A", ii) LA PELICULA FINA ABANDONA LA SUPERFICIE CALIENTE COMO COMPOSICION DE REACCION QUE CONTIENE POLIURETANOS/ POLIUREAS, Y iii) LA COMPOSICION DE REACCION SE ENFRIA ABRUPTAMENTE POR MEDIO DEL DISPOSITIVO DE ENFRIAMIENTO BRUSCO DESPUES DE ABANDONAR LA SUPERFICIE CALIENT. LOS COMPONENTES DE LA COMPOSICION DE REACCION DE PARTIDA ESTAN PRESENTES COMO UN COMPONENTE DE POLIISOCIANATO Y UN COMPONENTE DE POLIOL/ POLIAMINA
