Abstract

PROCEDIMIENTO DE OBTENCION DE MATERIA PLASTICA SINTETICA EN FORMA DE ESPUMA. CONSISTE EN HACER REACCIONAR UNA MEZCLA CONTENIENDO UN POLIOL, UN POLIISOCIANATO Y UN AGENTE DE SOPLADO. LA FORMACION DE ESPUMA SE REALIZA EN CONDICIONES DE PRESION CONTROLADA, EN UNA CAMARA DE REACCION CONECTADA A UNA BOMBA DE VACIO QUE SIRVE PARA MANTENER LA PRESION EN LA CAMARA POR DEBAJO DE LA PRESION ATMOSFERICA. LA CAMARA SE SOMETE A UNA PRESION POR MEDIO DE UNA BOMBA DE COMPRESION CONECTADA CON LA CAMARA. LA MEZCLA DE REACCION SE INTRODUCE EN LA CAMARA ANTES DE TERMINAR LA FORMACION DE LA ESPUMA; LA CAMARA DE CIERRA, SE CONTROLA LA PRESION EN EL INTERIOR MIENTRAS SE FORMA LA ESPUMA Y SE ABRE PARA RETIRAR LA ESPUMA, CUANDO LA FORMACION HA TERMINADO.
