SelsIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : The problems associated with tannery effluent have been addressed by Michell Leather, Australia, in such a way that the sludges and effluent have become an asset. Sludges from effluents treatment are now being injected into the soil for land conditioning and as fertiliser, and the supernatant used for crop irrigation.
This treatment has required some changes in processing to ensure that the traditional wastes can be best used, and include:
- selective use of bactericides and fungicides
- processing chilled or iced hides instead of salted hides
- using a closed loop system in pickling and tanning to minimise salt recovery
- full chrome recovery
- reationalised use ot waterNote de contenu : - Effluent and sludge treatment
- Managing land based disposal

Langues : Anglais (eng) Catégories : Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique.
L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

StratifiésIndex. décimale : 667.9 Revêtements et enduits Résumé : Polymers and metals greatly differ in their deformation behaviour when they are conformed as laminate composites. Knowledge of the conformation of a polymer in the interface region is an important aspect in understanding the mechanism of adhesion in the composite.
Characterisation and performance evaluations of the metal-polymer protective substrates, composed of a steel plate coated with electrolytic chromium (ECCS) and surface-protected by a poly(ethyleneterephthalate) (PET) co-rolled layer, were carried out by SEM (scanning electron microscopy) and TEM (transmission electron microscopy). The chemical composition and morphology of the components that allow for good adhesion of the metal-polymer plate were studied at the interface. ATR (attenuated total reflection), FT-IR (Fourier transform-infrared) and confocal Raman spectroscopy were employed to analyse the structural changes of the PET coatings on the ECCS plates resulting from the manufacturing processes and mechanical stresses.DOI : 10.1007/BF02699615 En ligne : https://link.springer.com/content/pdf/10.1007/BF02699615.pdf Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=5396

Fer
NickelLe nickel est un élément chimique, de symbole Ni et de numéro atomique 28.
Le nickel est un métal blanc argenté qui possède un éclat poli. Il fait partie du groupe du fer. C'est un métal ductile (malléable). On le trouve sous forme combinée au soufre dans la millérite, à l'arsenic dans la nickéline.
Grâce à sa résistance à l'oxydation et à la corrosion, il est utilisé dans les pièces de monnaie, pour le plaquage du fer, du cuivre, du laiton, dans certaines combinaisons chimiques et dans certains alliages. Il est ferromagnétique, et est fréquemment accompagné de cobalt. Il est particulièrement apprécié pour les alliages qu'il forme.

SiliciumIndex. décimale : 667.9 Revêtements et enduits Résumé : Thermally sprayed coatings that are based on FeSiNICr-related alloy powders are widely used to improve properties such as the surface hardness, the wear resistance and the corrosion resistance of a variety of coated metal substrate materials. For the current study, the FeSiNiCr-containing coating formulations were thermally sprayed onto a agrey cast iron substrate by the high velocity oxy fuel (HVOF) method under controlled conditions. The microstructure and micro abrasive wear performance of both the uncoates substrates and the coated substrates were characterized by optical microscopy as well as by scanning electron microscope (SEM).

Température de retraitIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : The system acrylic resin+ aluminium (HI) + chromium (III) has been investigated, as the basis of a novel tanning system. In particular, tannages containing very low or zero chromium (III) offers were investigated with a view to finding an alternative to full chrome tannage. High shrinkage temperature was the main aim of these experiments but other parameters were not ignored.
The colour of the leathers were essentially white, even when 1 % chromium (III) was present. There was no loss in thermal stability on soaking for 42 h in water at 30-35°c. Tear strength of fellmongered sheepskin leather was in excess of the 1976 GERIC guidelines for garment leather. Light fastness was better than 6 on the Blue Wool Scale.Note de contenu : - RESULTS : Tannages with increased polymer/reagent offer - The colour of aluminium tanned sheepskins - Tannages with polymer reagent, Aluminium and chromium - Tannage of whole sheepskins - Tannages with increased Aluminium offer

Tanins végétauxIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Due to stringent environmental regulation concerning the disposal of tannery waste products there is continuous research on discovering eco-friendly tanning reagents. Vegetable tannins are less polluting to the environment than chromium. A study has been conducted to evaluate the tannin content and tanning strength of selected vegetable tanning materials found in Laikipia County and their suitability for tanning hides and skins. The hide powder method was used in determining the amounts of tannins. Acacia nilotica, Acacia xanthophinea and Hagenia abyssinica had percentage tannins of 16.8%, 23.8%, 11.73% respectively and all of them had a tanning strength of more than 1.5.
