Un micro extrudeuse \u00e0 double vis<\/strong> de Hartek a \u00e9t\u00e9 install\u00e9, mis en service et exploit\u00e9 par une universit\u00e9 de Qingdao, dans la province de Shandong, et a \u00e9t\u00e9 officiellement livr\u00e9 au laboratoire du client pour utilisation. <\/p>\n\n\n\n

Cet \u00e9quipement est sp\u00e9cialement con\u00e7u pour le m\u00e9lange et la modification de mat\u00e9riaux polym\u00e8res \u00e0 l'\u00e9tat de traces, le criblage de formulations et la pr\u00e9paration en petits lots de mat\u00e9riaux de grande valeur. Sa structure compacte et ses capacit\u00e9s de m\u00e9lange efficaces apporteront un soutien technique essentiel aux projets de R&D sophistiqu\u00e9s des clients.<\/p>\n\n\n\n

La nouvelle livraison micro-extrudeuse \u00e0 double vis<\/a><\/strong> se caract\u00e9rise par une structure \u00e0 deux vis co-rotatives avec un diam\u00e8tre de vis de 11,7 mm et un rapport longueur\/diam\u00e8tre de 40:1. Par rapport aux \u00e9quipements d'extrusion de laboratoire traditionnels, son principal avantage r\u00e9side dans sa capacit\u00e9 \u00e0 r\u00e9aliser une exp\u00e9rience compl\u00e8te de m\u00e9lange et de granulation avec une quantit\u00e9 d'alimentation unique aussi faible que quelques dizaines de grammes. Il est donc particuli\u00e8rement adapt\u00e9 \u00e0 l'exploration de la formulation et \u00e0 l'optimisation des param\u00e8tres du processus pour les mat\u00e9riaux co\u00fbteux (tels que les polym\u00e8res m\u00e9dicaux, les plastiques techniques sp\u00e9cialis\u00e9s et les mat\u00e9riaux d'origine biologique). La machine int\u00e8gre l'extrudeuse, le syst\u00e8me de commande \u00e9lectrique et l'unit\u00e9 de micro-granulation optionnelle. Elle peut \u00eatre plac\u00e9e sur une paillasse de laboratoire standard, ce qui n\u00e9cessite un espace de laboratoire minimal.<\/p>\n\n\n\n

Les ing\u00e9nieurs de l'\u00e9quipement ont d'abord proc\u00e9d\u00e9 au positionnement de l'unit\u00e9 principale, aux connexions \u00e9lectriques et au d\u00e9bogage en ligne de chaque unit\u00e9 afin de garantir le fonctionnement stable et coordonn\u00e9 du syst\u00e8me d'extrusion et du syst\u00e8me de contr\u00f4le de la temp\u00e9rature. La formation op\u00e9rationnelle qui a suivi s'est concentr\u00e9e sur les fonctions de l'\u00e9quipement et le contr\u00f4le du processus, notamment :<\/p>\n\n\n\n

Op\u00e9ration de micro-alimentation<\/strong>: M\u00e9thodes d'ajout de mat\u00e9riaux et points de nettoyage des tr\u00e9mies pour les petits lots ;
R\u00e9glage de la temp\u00e9rature du processus :<\/strong> R\u00e9glage des temp\u00e9ratures de chauffage pour chaque zone du cylindre en fonction des caract\u00e9ristiques du mat\u00e9riau, d\u00e9marrage \u00e0 basse temp\u00e9rature et contr\u00f4le de la temp\u00e9rature constante pour les mat\u00e9riaux sensibles \u00e0 la chaleur ;
Observation et enregistrement de l'\u00e9tat de fusion<\/strong>: Surveillance et identification des anomalies dans les param\u00e8tres de pression et de temp\u00e9rature de fusion pendant le fonctionnement normal ;
Extrusion et pr\u00e9l\u00e8vement d'\u00e9chantillons<\/strong>: Op\u00e9ration de traction et m\u00e9thodes de pr\u00e9l\u00e8vement d'\u00e9chantillons pour les bandes extrud\u00e9es ;
Proc\u00e9dures de changement de mat\u00e9riel et de nettoyage<\/strong>: Nettoyage des vis, d\u00e9montage des fili\u00e8res et \u00e9tapes de nettoyage des \u00e9quipements lors du passage d'une formulation \u00e0 l'autre, en mettant l'accent sur les techniques de nettoyage rapide des \u00e9quipements de micro-alimentation ;
Entretien et \u00e9talonnage quotidiens :<\/strong> Inspection de l'\u00e9l\u00e9ment chauffant, cycle d'\u00e9talonnage du thermocouple et points cl\u00e9s pour l'inspection de l'\u00e9quipement.<\/p>","protected":false},"excerpt":{"rendered":"
