Les chercheurs qui travaillent sur de nouveaux mat\u00e9riaux en ont tous fait l'exp\u00e9rience : Ils produisent laborieusement un \u00e9chantillon en laboratoire \u00e0 l'aide d'un extrudeuse \u00e0 filer de bureau<\/strong>, et les performances semblent prometteuses. Cependant, lorsqu'ils s'appr\u00eatent avec confiance \u00e0 augmenter l'\u00e9chelle de la ligne de production, le produit obtenu manque de r\u00e9sistance, pr\u00e9sente une surface rugueuse ou ne peut tout simplement pas \u00eatre extrud\u00e9. Apr\u00e8s enqu\u00eate, la raison s'av\u00e8re \u00eatre que la force de cisaillement de l'\u00e9quipement \u00e0 petite \u00e9chelle \u00e9tait trop faible, ou que le temps de s\u00e9jour variait trop.<\/p>\n\n\n\n

Cela cr\u00e9e une situation d\u00e9licate : les donn\u00e9es des tests \u00e0 petite \u00e9chelle semblent bonnes, mais elles n'ont pas de valeur pour la mise \u00e0 l'\u00e9chelle. Pour obtenir des donn\u00e9es fiables \u00e0 l'\u00e9chelle pilote, il faut emprunter l'\u00e9quipement de la cha\u00eene de production, ce qui n\u00e9cessite des centaines de kilogrammes de mat\u00e9riel par d\u00e9marrage, d'o\u00f9 des co\u00fbts \u00e9lev\u00e9s, des cycles longs et des files d'attente fr\u00e9quentes.<\/p>\n\n\n\n

Le HARTEK extrudeuse \u00e0 filer de bureau<\/a><\/strong> est con\u00e7ue pr\u00e9cis\u00e9ment pour r\u00e9soudre le probl\u00e8me de la \u201cdistorsion de mise \u00e0 l'\u00e9chelle\u201d. Il ne s'agit pas d'une simple extrudeuse de bureau, mais d'une ligne de production industrielle de filature \u00e0 \u00e9chelle r\u00e9duite.<\/p>\n\n\n\n

Pourquoi les donn\u00e9es d'une machine \u00e0 filer de bureau peuvent-elles \u00eatre directement utilis\u00e9es pour la production de masse ?<\/h2>\n\n\n\n

La cl\u00e9 r\u00e9side dans deux points : Premi\u00e8rement, le taux de cisaillement et la capacit\u00e9 de m\u00e9lange distributif de l'extrudeuse bivis conique sont sp\u00e9cifiquement con\u00e7us pour ressembler \u00e9troitement au champ d'\u00e9coulement d'une grande extrudeuse bivis conique. Deuxi\u00e8mement, la fili\u00e8re, la pompe doseuse, la fili\u00e8re et les rouleaux d'\u00e9tirage sont tous adapt\u00e9s \u00e0 des normes industrielles, et non \u00e0 des simplifications de type \" jouet \". Cela signifie que la temp\u00e9rature optimale, la vitesse de la vis et le rapport de tirage trouv\u00e9s sur cet \u00e9quipement peuvent \u00eatre directement utilis\u00e9s comme param\u00e8tres initiaux pour les lignes de production \u00e0 grande \u00e9chelle.<\/p>\n\n\n\n

Sept grands domaines, une seule solution<\/h2>\n\n\n\n

    Researchers working on new materials have all experienced this: They painstakingly produce a sample in the lab using a desktop spinning extruder, and the performance seems promising. However, when they confidently prepare to scale up the production line, the resulting product either lacks strength, has a rough surface, or simply cannot be extruded.
