Abstract

UN DISPOSITIVO PARA LA MEZCLA AL MENOS DE DOS COMPONENTES REACTIVOS CONSISTE EN UNA CAMARA DE MEZCLADO CILINDRICA, DENTRO DE LA CUAL LOS COMPONENTES PLASTICOS SON INYECTADOS Y DONDE SE DISPONE DE UN EMBOLO REVERSIBLE, ASI COMO UNA CAMARA DE ESTABILIZACION CILINDRICA UNIDA A LA CAMARA DE MEZCLADO, CON PREFERENCIA EN UN ANGULO DE 90 EZA REVERSIBLE PARA LA EXTRACCION DE LA MEZCLA DE PLASTICO REACTIVO A PARTIR DE LA CAMARA DE ESTABILIZACION. PARA REDUCIR LAS FUERZAS EJERCIDAS SOBRE EL EMBOLO DE LIMPIEZA MEDIANTE LA MEZCLA DE PLASTICO Y PARA REDUCIR LAS FUERZAS DE DESGARRO SOBRE EL EMBOLO INMOVILIZADO A UN MINIMO SE PROPONE QUE SE DISPONGA DE UNA CAVIDAD SOBRE LA SUPERFICIE DE CAMISA CILINDRICA DEL EMBOLO DE LIMPIEZA, QUE ESTA RELLENA CON MATERIAL ESPACIADOR Y DISPUESTA DE ACUERDO CON EL PRINCIPIO DE QUE EL EMBOLO DE LIMPIEZA REALIZA UN MOVIMIENTO ROTATIVO AL MISMO TIEMPO QUE SU DESPLAZAMIENTO AXIAL.
