Titre : Enhanced acrylic technology for automotive topcoat finishes Type de document : texte imprimé Auteurs : E. Nungesser, Auteur ; J. Hoefler, Auteur Année de publication : 2005 Article en page(s) : p. 54-60 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The Rohm and Haas Company has developed a novel acrylic polymer technology for use in topcoat finishing formulations. Products making use of this unique polymer technology can deliver performance comparable to many polyurethane based materials, while providing the aesthetics and cost efficiency that can only be achieved with acrylic polymers. The key enabler in this technology is an acrylic bound-duller that provides comparable gloss, "jetness" and performance properties, at comparable loadings to many commercially available polyurethane based dulling materials. The technology is inherently solvent free, and is compatible with older acrylic and PUD resin components as well as conventional cross linking chemistries. This new technology will provide leather finishers with additional options in high quality finishes with enhanced economics.

Tannage -- Aspect de l'environnementIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The chemical coagulation of tannery wastewater can lower suspended solids and BOD to levels acceptable by publicity-owned treatment works (POTWs). Lime (Ca(OH)2), a suspended solid that exists as a colloid at high pHs, is very difficult to remove through simple sedimentation. The composite suspended solids for a Beam and Tan facility after clarification alone, ranges from 750 to 1500 mg/l. Flocculation of the wastewater before settling increased efficiency of removal and produced affluent suspended solids below 500 mg/l. Experiments with potassium permanganate, alum, carbon dioxide and polymers showed that addition of alum was a cost-effective means of reducing suspended solids. The large quantity of lime present in tannery wastewater provided sufficient alkalinity for floc formation and particle entrainment. The utilization of passive tube settlers and rapid sand filtration further enhanced solids removal.

RhéologieIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The global production of leather shavings (LSs) amounts to millions of tons annually, posing significant challenges in terms of resource waste and environmental pollution if not effectively managed. This study explores the utilization of LSs by fabricating modified leather fibers (MLFs) as reinforcing fillers to enhance the mechanical and thermal insulation properties of polyvinyl chloride (PVC) foams. The process involved pulverizing LSs and modifying them with a polyethylene glycol–isophorone diisocyanate (PEG–IPDI) prepolymer to create MLF. This MLF was then incorporated into PVC to produce MLF/PVC foam. The PEG–IPDI prepolymer modification aligned the surface free energy of MLF (33.82 ± 1.97 mJ/m2) with that of PVC (31.08 ± 3.65 mJ/m2), thereby improving their interfacial compatibility and imparting thermal energy storage capacity to the MLF. The resulting MLF/PVC foam exhibited enhancements in compressive strength and modulus, showing increases of 93.7% and 165.8%, respectively, compared to pure PVC foam. Furthermore, MLF/PVC foam demonstrated a slower surface temperature increase when heated using a heating plate at 110°C compared to pure PVC foam. These findings indicate that MLF enhances the mechanical and thermal insulation properties of PVC foams, primarily due to the improved foaming and thermal storage capacities imparted by the MLF.

With capital and running costs a fraction of the activated sludge process, the simplicity and elegance of this technology has been demonstrated in both equatorial and temperate regions. With performance and area requirements in line with today’s intrusive technology, these robust green systems offers a realistic alternative to the "high cost/high tech" route. There are also other opportunities... The following paper is combination of presentations to IULTCS Congress India 1999, SLTC 2000, and IULTCS Congress South Africa 2001.

PhytoépurationLa phytoépuration est au sens large l'épuration par les plantes. Celles-ci peuvent contribuer à épurer ou dépolluer les trois grands milieux que sont l'air, les sols et l'eau. Il s'agit d'un système de traitement des eaux utilisant des plantes (généralement plantes macrophytes), des substrats et des microorganismes au sein d'une zone humide artificielle (ou "constructed wetlands" pour les anglophones). Les systèmes de phytoépuration peuvent être composés d'un ou plusieurs filtres plantés.Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Root-zone systems utilise micro organisms hosted by the root structure of reeds to reduce the COD loading of supernatants following primary effluent treatment. In part 1 of this article (WL June/Jully 2001), these systems were described, detailling the performance and properties from pilot and large scale systems operating in the leather sector as an alternative to the activated sluge treatment process. However, the technology can be improved by a combinaison of good managemment and under-bed recirculation of effluent. Part 2 discusses the findings from systems where performance has been enhanced, and the potential of these systems as an alternative to the conventional biological treatment of tannery effluents.

- Fig. 11 : Seasonal performance and the effects of maturity. Enhanced root-zones operating with shorter retention times take longer to reach peak performance. When mature, they then match 5-day performance through summer-winter cycles
