Produits chimiques -- ToxicologieIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : ILM has previously covered "forever chemicals" in the November/December 2021 print/digital issue. In that magazine, the article warned that forever chemicals were being pressurised from ail parts of the globe and their inevitable end was real.
That end has arrived faster than mort people predicted. Per- and polyfluorinated allcyl substances (PFAS), also known as "forever chemicals", are a group of more than 9,000 highly persistent synthetic chemicals. PFAS contain alkyl groups in which hydrogen atoms are replaced by fluorine. Industrial application and use of PFAS in consumer products commenced in the 1940s. PFAS do not easily degrade in the environment due to the highly stable carbon-fluorine bond. This strong bond is responsible for the persistent nature of PFAS that enables these chemicals to build up within the environment and organisms.Note de contenu : - California

Environnement -- Etudes d'impactIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Recently, many machinery companies have been showcasing the abilityof their machines' user interface (UI) to tell the user what the carbon footprint of that machine operationi is. This article will explain what the user (tanner or finisher) is getting and whether it is useful. Note de contenu : - How is the footprint calculated ?
- Machine operation activity data

Maroquinerie
Modélisation tridimensionnelleIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : La CAO (Conception Assistée par Ordinateur) existe depuis les années 60. Initialement utilisée par les bureaux d'études dans la mécanique, elle s'est largement diffusée dans toutes les industries nécessitant la réalisation de plans techniques. Aujourd'hui, la CAO a bien évolué, elle permet la modélisation en 3D de systèmes complexes, allant jusqu'à simuler leur fonctionnement et les contraintes pouvant s'y appliquer. Note de contenu : - Les logiciels de CAO 3D
- Les gains potentiels grâce aux logiciels CAO 3D

Titre : Carbodiimides in leather finishing II : recent advances Type de document : texte imprimé Auteurs : L. C. J. Hesselmans, Auteur ; A. J. Derksen, Auteur ; W. Posthumus, Auteur ; J. Levy Année de publication : 2008 Article en page(s) : p. 393-395 Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The first paper in this series outlined the then-known chemistry of water-dispersible polycarbodiimides and demonstrated conclusively their utility for leather finishing, but at the same time revealed unexpected gaps in some of the chemical detail.
This presentation represents an update to an important leather industry audience and is one more in what is a longer series devoted to developing consensus understanding of the chemistry and benefits that accrue to the use of polycarbodiimide crosslinkers for specialty coatings. The search for continued performance imporvement in the most demanding areas of leather finishing continues, and the thrust of this paper and others in the series is to promote amore precise understanding of the complex chemistry of polycarbodiimides, to distill out from that larger chemical picture what reactios are most likely and deserve further study, and to ally that knowledge with what is taught by experience for the purpose of proposing, explaining, and justifying how best to use them to produce more cost-effective performance outcomes for the leather finisher.En ligne : https://drive.google.com/file/d/1UgcgDT74GSvVwt8DdK7lKwk6kot6AatJ/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=3026
