PSI-Polymer Systems, Inc. pr\u00e9sente un nouveau changeur de tamis \u00e0 contre-courant continu Hickory, NC (7 d\u00e9cembre 2004)<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

PSI-Polymer Systems Inc. a introduit un nouveau changeur d'\u00e9cran \u00e0 r\u00e9trobalayage continu (CSC\/BF), con\u00e7u pour une filtration extr\u00eamement fiable des polym\u00e8res dans une grande vari\u00e9t\u00e9 d'applications d'extrusion.<\/p>

Dot\u00e9 d'une conception unique, le nouveau CSC\/BF permet d'augmenter la dur\u00e9e de vie de l'\u00e9cran de filtration, d'au moins 25 fois par rapport aux conceptions typiques de changeur d'\u00e9cran continu. Une dur\u00e9e de vie accrue de l'\u00e9cran signifie des changements d'\u00e9cran moins fr\u00e9quents en raison du colmatage d\u00fb aux contaminants dans le plastique fondu. Cela se traduit par beaucoup moins de temps d'arr\u00eat, ce qui signifie une plus grande fiabilit\u00e9 et une plus grande productivit\u00e9 pour les processeurs. Un autre avantage cl\u00e9 du CSC \/ BF est qu'il r\u00e9duit la contre-pression sur l'extrudeuse \u00e0 une pression beaucoup plus faible, permettant ainsi une augmentation de la production - jusqu'\u00e0 une augmentation de 50% sur certains mat\u00e9riaux et processus.<\/p>

"L'id\u00e9e derri\u00e8re toute conception de changeur d'\u00e9cran continu est de permettre une production constante avec un minimum absolu de temps d'arr\u00eat", a d\u00e9clar\u00e9 Glenn Woodcock, pr\u00e9sident de PSI. "En divisant le flux de polym\u00e8re en deux flux, les transformateurs peuvent changer un tamis obstru\u00e9 sans interrompre la production."<\/p>

\u00ab Cette nouvelle unit\u00e9 de r\u00e9trobalayage am\u00e8ne ce concept \u00e0 un nouveau niveau. En purgeant automatiquement les contaminants des \u00e9crans obstru\u00e9s, il prolonge consid\u00e9rablement la dur\u00e9e de vie de l'\u00e9cran. Ce produit fonctionnera beaucoup plus longtemps sans avoir besoin d'entretien que n'importe quel changeur d'\u00e9cran conventionnel.<\/p>

Comment \u00e7a fonctionne<\/u><\/p>

Comme le changeur d'\u00e9cran continu existant de PSI, le nouveau CSC\/BF divise le polym\u00e8re entrant en deux flux, tous deux filtr\u00e9s dans les pistons sup\u00e9rieur et inf\u00e9rieur. Contrairement \u00e0 la conception CSC, cependant, le CSC\/BF poss\u00e8de deux cavit\u00e9s de filtration dans chaque piston, permettant une filtration deux fois sup\u00e9rieure \u00e0 la conception CSC de taille comparable.\u00a0<\/p>

L'aspect le plus unique du CSC\/BF est la capacit\u00e9 de \u00ab\u00a0recyclage\u00a0\u00bb ou de maximiser automatiquement la dur\u00e9e de vie de l'\u00e9cran. Lorsque la pression en amont augmente en raison d'un niveau \u00e9lev\u00e9 de contaminant dans le polym\u00e8re, la commande PLC actionne automatiquement chaque piston dans sa position de rin\u00e7age, permettant \u00e0 la pression de repousser les contaminants hors du tamis sale. Les contaminants sont purg\u00e9s des orifices du bo\u00eetier. Une fois que la s\u00e9quence de r\u00e9trobalayage se produit, les \u00e9crans \u00ab\u00a0recycl\u00e9s\u00a0\u00bb sont ramen\u00e9s \u00e0 la position d'origine jusqu'\u00e0 ce que la s\u00e9quence se reproduise.<\/p>

Caract\u00e9ristiques et avantages du CSC\/BF<\/u><\/p>

Comme la gamme de CSC de PSI, le nouveau CSC\/BF est garanti pour fonctionner sans fuite \u00e0 des pressions allant jusqu'\u00e0 10 000 psi et \u00e0 des temp\u00e9ratures allant jusqu'\u00e0 650 \u00b0F. Toutes les pi\u00e8ces sont fabriqu\u00e9es selon les normes ISO-9002. Sa conception robuste offre une excellente r\u00e9sistance \u00e0 l'usure, et sans joints ni pi\u00e8ces de contact, il n'y a pratiquement aucun entretien requis autre que le changement occasionnel de l'\u00e9cran.\u00a0<\/p>

Les applications typiques du nouveau changeur de tamis CSC\/BF comprennent le recyclage, les feuilles, les films souffl\u00e9s et les films coul\u00e9s, le compoundage, la granulation sous-marine et la granulation de brins, le rev\u00eatement par extrusion, les tuyaux et profil\u00e9s, les fils et c\u00e2bles, etc. PSI propose cinq tailles standard de changeurs d'\u00e9cran \u00e0 contre-courant, avec des d\u00e9bits allant de 1 000 \u00e0 10 000 lb\/h.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
