Solvatation
Transfert de masseIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : A practical manner on how tanneries can reduce the chemicals they use is a constant area of interest. Many tanneries actively practice research, development and innovation to do this. To remind readers of why this is important, it is useful to remember that a tannery's function is to make leather and it is not there to feed an effluent plant. The management of the tannery should make it a high priority to favour the principle that the chemistry should go into the leather and should not simply go down the drain.
The UNIDO position has often estimated the amount of input chemistry (per tonne) of materials as -400-500 kg. It also reports the estimate of wasted chemistry as -380 kg (Buljan and ICre, 2015). By best estimates, that is 75-95% of the chemicals added that are wasted - incredible.Note de contenu : - Why ?

Tannage au chrome
Tannage sans selsIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Tannery effluents with high salinity and containing chromium have a serious environmental impact. The traditional chrome tannage that involved the use of sodium chloride, acid and chromium is one of the main origins of salt and chromium pollution. In this study, a non-pickle, chrome-reduced tanning technology was developed. The novel chrome-free agent SL can be directly employed to tan bated bovine hide producing wet-white. The shaved wet-white was pre-treated by a poly-carboxylate auxiliary agent PAA and tanned by chrome powder. It was found that the shrinkage temperature of the wet-white tanned by SL reached over 80°C, the optimal consumption of poly-carboxylate auxiliary agent was 1.5- 2wt% based on the weight of the shaved wet-white, the better chrome-reduced tanning conditions were that the wet-white was tanned with 3-4wt% chromium powder for 150-180 minutes at room temperature when the initial pH value was 3.0-3.5. The next processes were same as those of a traditional chrome tannage. Meanwhile, the shrinkage temperature of the leather tanned by the chrome-reduced tannage reached more than 95°C, the absorption of chromium was 96%, the content of Cr2O3 in the effluent was under 200mg/L. For the chrome-reduced tanned leather,the absorption of dyestuff and fat-liquor reached 99.5% and 82.5% respectively. Compared with the traditional chrome tanning process, not only was the conventional pickling process eliminated, the process was shortened and reduced the pollution of sodium chloride. The process can reduce by 50% the consumption of chrome powder, improve the absorption of chromium and reduce the content of Cr2O3 in effluent. Note de contenu : - EXPERIMENTAL PROCEDURES : Materials - Tanning properties of the novel chrome-free agent SL - The properties of wet-white tanned by the novel chrome-free agent SL - Optimisation of the offer of chrome tanning agent in tanning process - The properties of poly-carboxylate auxiliary agent in the low-chrome tannage - Contrast experiment between chrome-reduced tanning and traditional chrome tanning - Pilot production of leather tanned by chrome-reduced tannage
- RESULTS AND DISCUSSION : Analysis of tanning properties of the novel chrome-free agent SL and its leather - Optimum initial pH of chrome tanning agent on shaved wet-white - Optimum offer of chrome tanning agent for shaved wet-white - Optimum offer of the poly-carboxylate auxiliary agent PAA in chrome-reduced tanning of shaved wet-white - Comparison of chrome-reduced tannage and traditional chrome tanning - The properties of leather tanned by chrome-reduced tannage from pilot productionEn ligne : https://drive.google.com/file/d/1_b6GCLclh8aX2f9oJk2AMc-M7-OyAz0H/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=33205
