Tannage Résumé : In order to evaluate if the tannery residue derived from an industry of rio grande do sul state could be used as fertilizer and amendment, laboratory assays and experiments were conducted with two red-yellow podzolic soils. The residue presented important elements to the plants' nutrition such as nitrogen (N), phosphorus (P), potassium (K), sulfur (S), calcium (Ca) and magnesium (Mg). In the residue, the heavy metals nickel (Ni), chromium (Cr), lead (Pb) and cadmium (Cd) were predominantly in nonavailable forms to the plants. It increased the pH and the cation exchange capacity of the soils and may be used to correct the pH of the acidic soils. In free drainage condition, the residue application, in rates varying from 0 to 11.1 g residue kg-1, did not show salinity problems to the soils and in spite of its high pH and high chromium content, in rates of 0, 4.4 and 8.3 g residue kg-1, it was not harmful to the rye growth.

Tannage organiqueIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : A kind of Y-shaped amphiphilic block polyurethane copolymers (PUGs) with different molecular weights were successfully synthesized to be used as retanning agent combined with polyacrylic acid (PAA) for modified glutaraldehyde tanned goatskin. The structures of resulting products were characterized by FTIR, and the molecular weights of products were measured with GPC. The application performances were investigated by measuring the organoleptic and physical mechanical properties of resulting leathers according to the alone or combined use of PUG and PAA, the molecular weight of PUG, and the offer percentage of retanning agent. The best performance was found in the leather retanned by PUG750 and PAA complex retanning agent at the total offer percentage of 4 wt%. Finally, the free formaldehyde contents in the leathers retanned with 4 wt% PUG750 and PAA at different pH conditions were analyzed with acetyl acetone colorimetric method. The mechanical properties as well as the fibers morphologies of the experimental and control groups were also investigated. The results demonstrated that when the pH value at the later stage of retanning process was controlled at 4.0 or 3.0, the free formaldehyde content was significantly reduced by 20.3% or 38% respectively ; and the physical mechanical properties of leathers were also very excellent to meet the performance requirements of goatskin garment leathers. According to these results, the method for using PUG and PAA as a complex retanning agent might be a good choice in chrome-free tanning process.

Tannage Résumé : The use of chromium(III) salts in tanning is under review by the global leather industry. The currently employed tanning methods lead to considerable waste of the chromium(III) salts used. An alternative mineral tanning salt based on zirconium named as Organozir has been developed. Mechanistic insight into tanning with Organozir has been gained through indirect studies. A case for invoking multi-point fixation of Organozir and the possible implications of both electrovalent and hydrogen bonding forces has been made.

Industrie 4.0Le concept d’Industrie 4.0 correspond à une nouvelle façon d’organiser les moyens de production : l’objectif est la mise en place d’usines dites "intelligentes" ("smart factories") capables d’une plus grande adaptabilité dans la production et d’une allocation plus efficace des ressources, ouvrant ainsi la voie à une nouvelle révolution industrielle. Ses bases technologiques sont l'Internet des objets et les systèmes cyber-physiques.

PolycarbodiimideTags : 'Finition du cuir' Polycarbodiimide 'Résine acrylique' 'Vitesse de réticulation' Tannage/retannage Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : In the current economic climate leather factories need to redesign their processes to add value to their production in order to increase their competitiveness. In this respect, the use of a cross-linker opens up opportunities for the leather industry to obtain both high performance and eco-friendly articles. This study explores the cross-linking reaction between a polycarbodiimide and both acrylic resins and polyurethanes.
A comparison of results shows that polycarbodiimide is a very selective cross-linker since it presents both different reticulation speeds and different cross-linking reaction rates depending on the type of binder employed. In addition, and depending on the type of tanned/retanned leather used, different amounts of polycarbodiimide are required in order to obtain optimum results.En ligne : https://drive.google.com/file/d/1bSzugBa6E16r4BGKvwUEpGKzb_VQEC4n/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=9626
