[article]
Titre : Wave behavior in the coating process of multilayer polymeric materials Type de document : texte imprimé Auteurs : Y.-Y. Su, Auteur Année de publication : 1999 Article en page(s) : p. 83-89 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 668.9 Polymères Résumé : A mathematical analysis model of multilayer viscoelastic fluids flowing down an inclined plane for any arbitrary wave numbers has been established to improve multilayer product quality in the coating processes. In the stability study of the free surface with small elastic force, Reynolds number is the primary parameter to induce surface instability for long and intermediate waves. When the elastic force in either layer is large, elasticity can affect the stability of long and intermediate waves. In addition, viscosity stratification across the interface can also affect the stability of the free surface. For the interfacial stability of two-layer flow system, it is found that purely elastic instability occurs in most depth ratios for the whole spectrum of waves when the fluid with elasticity is placed as the inner layer next to the solid wall. In the study of stability for viscoelastic fluids it demonstrates that arranging the more elastic and less viscous fluid as the outer layer leads to interfacial stability. In the more than three-layers investigation we found that placing the most viscous and least elastic liquid as the innermost layer next to the solid wall and the least viscous and most elastic liquid as the outermost layer next to the passive air can ensure the stability for the whole spectrum of waves.

[article]
Titre : Weld line strength in PC/ABS injection moldings Type de document : texte imprimé Auteurs : T. Semba, Auteur ; H. Hamada, Auteur Année de publication : 1999 Article en page(s) : p. 365-369 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 668.9 Polymères Résumé : Molding - Polycarbonate(PC)/ABS is a very common immiscible polymer blend. The internal structure such as distribution of each component in the injection moldings of PC/ABS would be strongly affected by the processing parameters. Especially, the weld line formed by meeting two melt flows and the internal structure at the weld area would be a very complex form. By observing the etched samples of PC/ABS injection moldings using scanning electron microscopy, a weld part with fine dispersion of ABS was found in the area below V-notch. When tensile load was applied perpendicular to the weld line, the fracture initiated from the V-notch, but the crack propagated along the interface between the weld part with fine dispersion and the part behind the weld part. This leads to unique characteristics of the weld strength. DOI : 10.3139/217.1547 Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=16126

Ding, Auteur Année de publication : 1999 Article en page(s) : p. 152-158 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 668.9 Polymères Résumé : Die extrusion - An analytical solution is presented for wire coating by drawdown of an extruded annular melt. The solution is developed with the assumption that the pressures inside and outside the film are equal ; a process in which these pressures differ, such as a vacuum inside the film, is treated as a limiting case.
