Chlorure de sodium Le chlorure de sodium est un composé chimique de formule NaCl. On l'appelle plus communément sel de table ou de cuisine, ou tout simplement sel dans le langage courant. C'est le principal produit dissous dans l'eau de mer ; on l'appelle alors sel marin.
On l'obtient : dans des marais salants par évaporation de l'eau de mer, dans des mines, par extraction du sel gemme (halite) ou en le synthétisant lors de réactions à hautes températures entre du dichlore (Cl2) et du sodium métallique (Na).
Le chlorure de sodium est utilisé dans l'industrie chimique pour produire du chlore, de la soude caustique et de l’hydrogène.

Résumé : |
The curing of raw hides and skins using sodium chloride salt is a widely recognized technique, although it has negative consequences for the environment by elevating water salinity and introducing a significant amount of Total Dissolved Solids (TDS). In order to tackle this issue, goat skin was conserved through the utilization of a mixture consisting of crushed sky fruit seeds and sodium chloride salt. Various ratios of mixtures were applied to raw goat skin to determine an optimal outcome. The most favorable result was achieved by utilizing a blend of 10% seed crush and 10% salt, based on the weight of the raw skin. A control specimen was run with the experimental specimen, and preservation-related variables such as odor, hair loss, shrinkage temperature, moisture level, and bacterial population were evaluated. After preservation, the experimental sample and a control sample were subjected to the standard leather processing technique. The liquor from both samples was analyzed to confirm the impact of the environment on preservation. The experimental trial indicated a 59% decrease in total dissolved solids (TDS) and a 44% reduction in chloride (Cl−) content. The processed leather samples were assessed for their quality through an analysis of their physical properties. Besides, the fiber structures were assessed using a scanning electron microscope (SEM). The comparative evaluation of the physiochemical properties of the introduced preservation showed superb results with the hope of new preservation possibilities. |
