Spectroscopie d'impédance électrochimiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : A waterborne acrylic coating doped with pH sensitive colophony microcapsules containing corrosion inhibitors was studied on carbon steel plates. The changes in the physical properties of the coatings were studied. The microcapsule coating specimens maintained more noble E.„ values compared to the control in deionised water and simulated concrete pore solutions with -513 and -531 mVSCE, respectively. Additionally, the microcapsule polarisation results for both pH12.6 and 6.2 electrolyte solutions showed lowerieO values of 1.20 x 10-' and 3.24 x 10-6 A . cm', respectively, compared to the control sample (1.15 x 10-5 and 4.21 x 10-5 A . cm2). Therefore, the microcapsule coating provided more protection from chloride attack on the substrate as well as the deleterious effects of low pH on carbon steel. The electrochemical impedance spectroscopy analysis corroborated the DC polarisation results, showing increased corrosion resistance for the microcapsule coated specimens compared to the control. Moreover, the Rpore and Ra are much higher than the control, indicating the protection of the inhibitors. The Ced, also shows lower values for the microcapsule coating than the control, showing a more protective and less doped double layer.

Substances per- et polyfluoroalkylées -- Suppression ou remplacementIndex. décimale : 667.9 Revêtements et enduits Résumé : As demonstrated by two different test methods, an acrylic produced without PFAS can meet the surfactant leach resistance of a PFAS-containing acrylic developed specifically for this purpose. With one exception, other performance properties for the acrylic produced without PFAS, such as hiding power, gloss development, and dirt pick-up resistance, remained at least equivalent to those of older acrylic technologies. Although block resistance, a paint-performance property attributed to PFAS, was not as pronounced in the new acrylic produced without PFAS, performance was not completely absent. Paint performance may therefore be preserved through creative polymer design, and further modulated through formulation techniques and the incorporation of additives, effectively demonstrating that a more environmentally sound acrylic can be a viable alternative to conventional all-acrylic latexes.

Vanadate de bismuthIndex. décimale : 667.9 Revêtements et enduits Résumé : This proper dispersion stabilisation of pigments is not only important for the final properties of a coating, it also helps pigments to be used as efficiently as possible. Peak performance on a broad range of pigments can be achieved using a dual-dispersant approach. Two complementary dispersants were each designed to have an optimum performance with a selected group of pigments and at the same time to guarantee inter-compatibility.

[article]
Titre : Improvements for infrared drying : A leather finishing application Type de document : texte imprimé Auteurs : S. Jöns, Auteur ; S. Alonso, Auteur ; R. Zitzumbo-Guzman, Auteur ; J. ornelas-Rodriguez, Auteur Année de publication : 2008 Article en page(s) : p. 162-166 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Analyse de variance En statistique, l'analyse de la variance (terme souvent abrégé par le terme anglais ANOVA : ANalysis Of VAriance) est un ensemble de modèles statistiques utilisés pour vérifier si les moyennes des groupes proviennent d'une même population. Les groupes correspondent aux modalités d'une variable qualitative (p. ex. variable : traitement; modalités : programme d'entrainement sportif, suppléments alimentaires ; placebo) et les moyennes sont calculés à partir d'une variable continue (p. ex. gain musculaire).
Ce test s'applique lorsque l'on mesure une ou plusieurs variables explicatives catégorielles (appelées alors facteurs de variabilité, leurs différentes modalités étant parfois appelées "niveaux") qui ont de l'influence sur la loi d'une variable continue à expliquer. On parle d'analyse à un facteur lorsque l'analyse porte sur un modèle décrit par un seul facteur de variabilité, d'analyse à deux facteurs ou d'analyse multifactorielle sinon. (Wikipedia)

Transfert radiatifIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The use of alternative technologies in leather finishing such as infrared radiation provides a faster and more efficient heat transfer for drying water-based films than the commonly used convection technology. In industry, all products and processes must be subjected to improvements, and infrared applications are no exception. The purpose of this research is to demonstrate how the heat transfer efficiency of an infrared furnace can be increased by adapting radiation shields along the infrared panels inside the drying tunnel. A theoretical analysis of the radiative heat transfer, a response surface model for evaporation percentage, and the measurement of the temperature at the walls were carried out to assess the performance of the new design. This paper may be useful to the leather industry in optimizing the finish film drying process and thus reducing leather manufacturing costs.
