A dilatometer to measure the influence of cooling rate and melt shearing on specific volume / M. H. E. van der Beek in INTERNATIONAL POLYMER PROCESSING, Vol. XX, N° 2 (06/2005)
[article]
Titre : A dilatometer to measure the influence of cooling rate and melt shearing on specific volume Type de document : texte imprimé Auteurs : M. H. E. van der Beek, Auteur ; Han E. H. Meijer, Auteur ; G. W. M. Peters, Auteur Année de publication : 2005 Article en page(s) : p. 111-120 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 668.9 Polymères Résumé : We developed a dilatometer to investigate the specific volume of polymers as a function of pressure (to 100MPa), temperature (to 260°C), cooling rate (to 100°C/s), and shear rate (to 801/s). The dilatometer is based on the principle of confined compression and comprises of a pressure cell used in combination with a tensile testing machine with rotation capability. The design of the pressure cell is a mixture of a traditional ‘pistondie type’ dilatometer and a Couette rheometer, i.e. piston and die make up an annular shaped sample spacing. Typical dimensions of annular samples are: inner radius ri = 10.5mm, outer radius ro = 11.0mm, height h = 2.5mm, and a typical mass of about 60 to 70mg. Silicon grease is used to reduce loss of hydrostatic pressure in the sample due to friction occurring between the solidifying sample and the dilatometer wall. Specific volume measurements at low cooling rate using an isotactic polypropylene (i-PP) are compared with measurements performed using a commercial bellows type dilatometer, showing relative differences in the range of 0.1 to 0.4%. Finally, results for an isotactic polypropylene are presented showing a profound influence of cooling rate and melt shearing on the evolution of specific volume.

Titre : A direct 3D numerical simulation code for extrusion and mixing processes Type de document : texte imprimé Auteurs : Rudy Valette, Auteur ; T. Coupez, Auteur ; C. David, Auteur ; Bruno Vergnes, Auteur Année de publication : 2009 Article en page(s) : p. 141-147 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 668.9 Polymères Résumé : This work focuses on the development of a general finite element code devoted to the three-dimensional direct simulation of mixing processes of complex fluids. The code, developed from the CimLib© Library, is based on a domain immersion method coupled with a "level-set" approach to represent the rigid moving boundaries, such as screws and rotors, as well as free surfaces. These techniques, combined with the use of automatized parallel computing, allow calculating the time-dependent flow of generalized Newtonian fluids in large and complex processes, involving moving free surfaces which are treated by a level-set/Hamilton-Jacobi method. Three examples of flow case studies are presented in this paper: the flow within the mixing section of a twin-screw extruder, the flow in an internal mixer and the flow in a batch mixer.

Réservoirs (récipients)Index. décimale : 668.9 Polymères Résumé : La fluoration directe des polymères présente de nombreux avantages au niveau industriel. En effet, en raison de la forte exothermicité des principales étapes élémentaires, la fluorination se produit spontanément dès la température ambiante dans la plupart des cas. De plus, c’est une technologie sèche qui permet de traiter des objets en polymère de formes très variées. Ces caractéristiques de la fluoration directe font que cette méthode est largement utilisée dans l’industrie pour améliorer l’étanchéité des réservoirs à essence en polymère ainsi que celle des récipients de stockage de produits toxiques, et également pour renforcer les propriétés d’adhésion. Elles permettent aussi d’améliorer fortement la sélectivité des membranes polymères pour la séparation des gaz.

PolycarbonatesIndex. décimale : 668.9 Polymères Résumé : This study proposes a simple technology using electromagnetism to control the direct hot imprint resist of a nickel mold. Combining the present gas-assisted hot imprint molding technology, electroforming technology, and self-designed heatable electromagnetic plate for even control and progressive pressuring technology, this study used electromagnetic nickel mold direct hot imprint to replicate microstructures, in order to make the molding technology and application of micro/nanoimprint more mature. This study first used gas-assisted hot embossing method to replicate structures on polycarbonate (PC), this PC film with microstructures is cast into nickel molds by electroforming. This nickel mold was used as the mold for magnetic embossing to imprint hot plastic polymethylmethacrylate (PMMA). The result showed that through gas-assisted hot embossing molding and electroforming, molds with high costs and complicated production processes can be massively replicated, and the replication precision is good. Through electroforming, the casting duration of magnetic nickel molds can be shortened and costs can be effectively lowered. Moreover, an electromagnetic plate was used to evenly control the direct hot pressure imprint resist, which is an advantage of the production process for micro structures.

Titre : Direct measurement of fiber temperature in the continuous drawing process of PET fiber heated by CO2 laser radiation Type de document : texte imprimé Auteurs : W. Okumura, Auteur ; T. Yamaguchi, Auteur ; Y. Ohkoshi, Auteur ; Y. Gotoh, Auteur ; M. Nagura, Auteur Année de publication : 2002 Article en page(s) : p. 124-132 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 668.9 Polymères Résumé : Poly(ethylene terephtalate) (PET) fiber was heated by carbon dioxide laser radiation during the continuous drawing process. Numerical calculation shows that the PET fiber can be heated much more rapidly and uniformly by heat radiation than by convective heat transfer through the fiber surface. During CO2 laser heated drawing, temperature in the vicinity of a neck-like deformation can be measured on-line with high precision, because the neck-like deformation is located within a range of 0.5 mm. We measured the fiber temperature profiles on the drawing process by IR thermometer that has a range resolution of 0.355 mm. The temperature at which neck-like deformation of the fiber initiates is higher than Tg when draw ratio is less than 4.5, but lower than Tg when draw ratio is more than 5.5. The maximum fiber temperature in the drawing process increases with draw ratio, up to 208°C for a draw ratio of 6.0. The rate of orientation-induced crystallization in the drawing process was estimated by comparison of measured temperature profiles with calculated temperature profiles.
