Le processus d'extrusion de feuilles de PET dans les machines TZ utilise une conception sp\u00e9cialis\u00e9e qui \u00e9limine le besoin d'\u00e9tapes traditionnelles de cristallisation et de s\u00e9chage, tout en incorporant des caract\u00e9ristiques avanc\u00e9es pour l'efficacit\u00e9 et l'automatisation.

Syst\u00e8me d'extrusion \u00e0 engrenages plan\u00e9taires :<\/strong>
- Le pr\u00e9sent Ligne de production de feuilles PET<\/a> utilise une \"conception d'engrenage plan\u00e9taire \u00e0 vis multiples\" (entourant une vis centrale principale<\/strong><\/span>) pour une fusion et un m\u00e9lange de qualit\u00e9 sup\u00e9rieure.
- Cette conception am\u00e9liore le transfert de chaleur, r\u00e9duit les contraintes de cisaillement et garantit une consistance uniforme de la mati\u00e8re fondue.
- D\u00e9gazage sous vide : Les mati\u00e8res volatiles et l'humidit\u00e9 sont \u00e9limin\u00e9es par des \u00e9vents sous vide pendant l'extrusion, ce qui \u00e9limine la n\u00e9cessit\u00e9 d'un pr\u00e9s\u00e9chage et d'une pr\u00e9cristallisation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

- La mati\u00e8re fondue passe par un \"changeur de tamis\" pour filtrer les impuret\u00e9s.
- Une \"pompe \u00e0 engrenages\" maintient une pression et un d\u00e9bit pr\u00e9cis pour une \u00e9paisseur constante.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

- La mati\u00e8re fondue est extrud\u00e9e \u00e0 travers une \"fili\u00e8re d'extrusion Jctimes\" pour former une feuille continue.
- Calandrage \u00e0 rouleaux : Le PET fondu est refroidi et mis en forme par une pile de 3 rouleaux de pr\u00e9cision (verticaux ou horizontaux) afin d'obtenir l'\u00e9paisseur et la finition de surface souhait\u00e9es.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

- Rouleaux de refroidissement : La feuille est refroidie progressivement pour assurer sa stabilit\u00e9 dimensionnelle.
- Enduction d'huile : Une fine couche d'huile est appliqu\u00e9e pour am\u00e9liorer la douceur de la surface et pr\u00e9venir l'\u00e9lectricit\u00e9 statique.
- Four de chauffage (en option) : Certaines lignes peuvent inclure un four pour le recuit ou un traitement thermique suppl\u00e9mentaire afin d'am\u00e9liorer les propri\u00e9t\u00e9s m\u00e9caniques.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
