Abstract

PARA EL RECUBRIMIENTO INTERNO CONTINUO DE UN PERFIL HUECO, RIGIDO, EXTRUSIONADO DE PLASTICO TERMOPLASTICO, SE EXTRUSIONA UN PLASTICO TERMOPLASTICO RIGIDO CON UNA TEMPERATURA DE TRANSICION VITREA SUPERIOR A 50 (GRADOS) C CONTINUAMENTE EN UN RAMAL DE PERFIL HUECO Y DESPUES DEL ENFRIAMIENTO INFERIOR A LA TEMPERATURA DE TRANSICION VITREA CON CURVADO ELASTICO, SE CONDUCE A TRAVES DE UN TRAYECTO EN FORMA DE ARCO CURVADO HACIA ABAJO, DONDE LA PARED INTERIOR DEL RAMAL HUECO ENTRA EN CONTACTO CON UNAS EXISTENCIAS QUE PERMANECEN ESTACIONARIAS DE UN PRODUCTO DE RECUBRIMIENTO MUY FLUIDO CAPAZ DE HUMEDECER EL PLASTICO TERMOPLASTICO. DESPUES DE PASAR POR ESTA SECCION DEL TRAYECTO SE CONDUCE HACIA ARRIBA EL RAMAL DE CAMARA HUECA TANTO TIEMPO HASTA QUE EL EXCESO ARRASTRADO DE PRODUCTO DE RECUBRIMIENTO FLUIDO VUELVE A LAS EXISTENCIAS. A CONTINUACION SE ENDURECE EN UN REVESTIMIENTO SOLIDO LA PELICULA DEL PRODUCTO DE RECUBRIMIENTO QUE HA QUEDADO SOBRE LA SUPERFICIE DEL PLASTICO.
