Title
(EN) LIQUID INJECTION BARREL ELEMENT FOR BARREL EXTRUDER
(FR) ÉLÉMENT DE CYLINDRE D'INJECTION DE LIQUIDE POUR EXTRUDEUSE À CYLINDRE
Abstract
(EN)
Described herein is a liquid injector for a barrel extruder as well as methods and processes of manufacturing irradiation crosslinked polypropylene foam. In some embodiments, this includes a liquid injection barrel element (5) that is incorporated in an extruder barrel that includes at least one injection port (11), a temperature sensor well (22), and cooling channels (19, 20).
(FR)
L'invention concerne un injecteur de liquide pour une extrudeuse à cylindre ainsi que des procédés et des processus de fabrication de mousse de polypropylène réticulée par irradiation. Selon certains modes de réalisation, il s’agit d’un élément de cylindre d'injection de liquide (5) qui est incorporé dans un cylindre d'extrudeuse qui comprend au moins un orifice d'injection (11), un puits de capteur de température (22) et des canaux de refroidissement (19, 20).
