(FR) PROCÉDÉ POUR LA PRÉPARATION D'UNE MASSE DE MOULAGE THERMOPLASTIQUE
(DE) VERFAHREN ZUR HERSTELLUNG EINER THERMOPLASTISCHEN FORMMASSE
Abstract:
(EN) A method for producing a thermoplastic moulding compound by means of an extruder (10), which comprises at least one feed zone (20), at least one mixing section (30), at least one venting section (40) and at least one discharge zone (50), wherein in the at least one feed zone (20) a water-containing first component and a second component are supplied, in the at least one mixing section (30) the thermoplastic moulding compound is mixed and contained water is evaporated, in the at least one venting section (40) water vapour is removed from the moulding compound and in the at least one discharge zone (50) the moulding compound is discharged. At least one of the mixing housings (31, 32) is kept at a temperature that is equal to or lower than the temperature of the moulding compound within the mixing section (30).
(FR) L'invention concerne un procédé pour la préparation d'une masse de moulage thermoplastique au moyen d'une extrudeuse (10), qui comprend au moins une zone d'introduction (20), au moins une section de mélange (30), au moins une section de dégazage (40) et au moins une zone de sortie (50), un premier composant contenant de l'eau ainsi qu'un deuxième composant étant introduits dans ladite au moins une zone d'introduction (20), la masse de moulage thermoplastique étant mélangée et l'eau contenue étant évaporée dans ladite au moins une section de mélange (30), la vapeur d'eau étant éliminée de la masse de moulage dans ladite au moins une section de dégazage (40) et la masse de moulage étant évacuée dans ladite au moins une zone d'évacuation (50). Ce faisant, au moins un des carters de mélange (31, 32) est maintenu à une température qui est égale ou inférieure à la température de la masse de moulage à l'intérieur de la section de mélange (30).
(DE) Verfahren zur Herstellung einer thermoplastischen Formmasse mittels eines Extruders (10), der mindestens eine Eintragszone (20), mindestens einen Durchmischungsabschnitt (30), mindestens einen Entgasungsabschnitt (40) und mindestens eine Austragszone (50) umfasst, wobei in der mindestens einen Eintragszone (20) eine Wasser enthaltende erste Komponente sowie eine zweite Komponente zugeführt werden, in dem mindestens einen Durchmischungsabschnitt (30) die thermoplastische Formmasse durchmischt wird und enthaltenes Wasser verdampft wird, in dem mindestens einen Entgasungsabschnitt (40) Wasserdampf aus der Formmasse entfernt wird und in der mindestens einen Austragszone (50) die Formmasse ausgetragen wird. Dabei wird zumindest eines der Durchmischungsgehäuse (31, 32) auf einer Temperatur gehalten, die gleich oder geringer ist als die Temperatur der Formmasse innerhalb des Durchmischungsabschnitts (30).
