Abstract

EN UN DISPOSITIVO PARA LA MEZCLA DE AL MENOS DOS COMPONENTES DE MATERIAL SINTETICO REACTIVO SON INYECTADOS LOS COMPONENTES DE MATERIAL SINTETICO BAJO ALTA PRESION EN UNA CAMARA DE MEZCLA CILINDRICA (1) Y ALLI SON ENERGICAMENTE MEZCLADOS. EN LA CAMARA DE MEZCLA SON CONDUCIDOS EMBOLOS DE CAMARA DE MEZCLA REVERSIBLES. LA MEZCLA DE LOS COMPONENTES DEL MATERIAL SINTETICO SE PRECIPITA DE LA CAMARA DE MEZCLA CILINDRICA A UNA CAMARA DE ESTABILIZACION (4) DISPUESTA EN UN ANGULO DE LA CAMARA EN LA QUE UN EMBOLO DE CAMARA DE ESTABILIZACION (5) ES REVERSIBLE. PARA EVITAR, QUE PARA LA DISTRIBUCION DE LA PRESION EN LA CAMARA DE MEZCLA DE LOS EMBOLOS DE LA CAMARA DE ESTABILIZACION, DEBAN SER BLOQUEADOS EN UNA POSICION, EN LA QUE ESTA BAJO LA MANTENCION LIBRE DE UNA RANURA DE CHOQUE ES RECUBIERTA EN PARTE LA ABERTURA DE SALIDA DE LA CAMARA DE MEZCLA; UNA SEGUNDA CAMARA DE ESTABILIZACION (6) ESTA DISPUESTA EN ANGULO A LA CAMARA DE ESTABILIZACION, EN LA QUE ESTA COLOCADO UN SEGUNDO EMBOLO REVERSIBLE (7).
