Title
(EN) HEATING APPARATUS FOR HEATING PARISONS OF THERMOPLASTIC MATERIAL
(FR) APPAREIL DE CHAUFFAGE POUR CHAUFFER DES PARAISONS EN MATÉRIAU THERMOPLASTIQUE
Abstract
(EN)
A heating apparatus (1) for heating parisons (100) of thermoplastic material, comprising: a tunnel (2) in which the parisons (100) move forward along a predefined direction; a plurality of infrared or near infrared emitters (4) located inside said tunnel (2) in such a way as to radiate the parisons (100) moving forward; at least one reflector (5) having a metallic substrate (6), said reflector (5) being positioned in such a way as to receive at least partially the radiation emitted by the infrared emitters (4) to reflect them, characterised in that the metallic substrate (6) of the reflector (5) is coated by an external layer (7) made of polysilazane or polysiloxane.
(FR)
Cette invention concerne un appareil de chauffage (1) pour chauffer des paraisons (100) de matériau thermoplastique, comprenant : un tunnel (2) dans lequel les paraisons (100) se déplacent vers l'avant le long d'une direction prédéfinie ; une pluralité d'émetteurs de rayonnement infrarouge ou infrarouge proche (4) situés à l'intérieur dudit tunnel (2) de manière à irradier les paraisons (100) se déplaçant vers l'avant ; au moins un réflecteur (5) ayant un substrat métallique (6), ledit réflecteur (5) étant positionné de manière à recevoir au moins partiellement le rayonnement émis par les émetteurs de rayonnement infrarouge (4) pour le réfléchir, caractérisé en ce que le substrat métallique (6) du réflecteur (5) est revêtu d'une couche externe (7) en polysilazane ou polysiloxane.
