1.Propri\u00e9t\u00e9 du produit<\/h4>\n

Le sulfite de sodium est une substance inorganique dont la formule chimique est Na2<\/sub>SO3<\/sub>. Il s'agit du sel de sulfite de sodium. Il est principalement utilis\u00e9 comme stabilisateur pour les fibres artificielles, comme agent de blanchiment pour les tissus, comme r\u00e9v\u00e9lateur pour la photographie, comme d\u00e9soxydant pour la teinture et le blanchiment, comme agent r\u00e9ducteur pour les parfums et les teintures, et comme agent de d\u00e9gradation du bois pour la fabrication du papier.<\/p>\n

3. Champ d'application et utilisation<\/h4>\n

Il est principalement utilis\u00e9 comme stabilisateur pour les fibres artificielles, agent de blanchiment des tissus, r\u00e9v\u00e9lateur photographique, d\u00e9colorant des teintures, agent aromatique et agent r\u00e9ducteur des teintures, et agent d'\u00e9limination de la lignine pour la fabrication du papier.<\/p>\n

 <\/p>\n

4. l'emballage et le stockage<\/h4>\n

Le sulfite de sodium anhydre est conditionn\u00e9 dans des sacs en papier kraft recouverts d'un film PE de 25 kg ou dans des sacs en plastique tiss\u00e9. Pour les produits de qualit\u00e9 alimentaire, des mesures de protection contre l'humidit\u00e9 \u00e0 double couche sont n\u00e9cessaires. Il doit \u00eatre stock\u00e9 dans un entrep\u00f4t frais et sec (<30\u2103), ferm\u00e9 herm\u00e9tiquement pour \u00e9viter l'humidit\u00e9 et l'air (il est sujet \u00e0 l'oxydation), et tenu \u00e0 l'\u00e9cart des acides et des oxydants. Pendant le fonctionnement, assurer une bonne ventilation (car la d\u00e9composition produit du SO\u2082). La dur\u00e9e de conservation est de 24 mois.<\/p>","protected":false},"excerpt":{"rendered":"
