Abstract
REACTOR DE EXTRUSORA. CONSISTE EN UNA EXTRUSORA QUE TIENE UNA ZONA DE FUSION, UNA ZONA INDEPENDIENTE PARA LA ADICION DE MONOMERO, UNA ZONA PARA LA ADICION DE INIACIADOR Y UNA ZONA DE DESVOLATILIZACION; LA ZONA DE ADICION DE MONOMERO TIENE POR LO MENOS UN TORNILLO CON PALETAS DE FORMA QUE LA ADICION DE MONOMERO TIENE LUGAR SOBRE TODAS LAS ROSCAS BAJO PLENA PRESION PERO NO BAJO ALTA CIZALLADURA. EL POLIMERO SE INTRODUCE A TRAVES DE UN PASO DE ALIMENTACION SE FUNDE Y SE ENVIA A LA ZONA DE ADICION DE MONOMERO, LIMITADA POR DOS SEGMENTOS NO PROVISTOS DE PALETAS MONTADOS SIN JUEGO. SALIENDO DE LA ZONA DE ADICION DE MONOMERO, LA MEZCLA DE MONOMERO-POLIMERO SE ENVIA A LA ZONA DE ADICION DEL INICIADOR, CUYOS EXTREMOS ESTAN ASIMISMO LIMITADOS POR SEGMENTOS QUE LIMITAN EL MOVIMIENTO DEL MONOMERO-POLIMERO Y DEL INICIADOR HASTA QUE HA TENIDO LUGAR LA MEZCLA TOTAL Y UNIFORME DE LOS MATERIALES. LA ZONA DE REACCION ESTA LIMITADA EN SUS EXTREMOS POR SECCIONES MONTADAS SIN JUEGO QUE IMPIDEN EL CONTRAMEZCLADO.
