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

L'hydroxyde de sodium, \u00e9galement connu sous le nom de soude caustique, a pour formule chimique NaOH. Il s'agit d'une base forte tr\u00e8s corrosive. Il se pr\u00e9sente g\u00e9n\u00e9ralement sous la forme de comprim\u00e9s ou de granul\u00e9s blancs et peut se dissoudre dans l'eau pour former une solution alcaline. Il peut \u00e9galement se dissoudre dans le m\u00e9thanol et l'\u00e9thanol. Cette substance alcaline poss\u00e8de des propri\u00e9t\u00e9s hygroscopiques et absorbe la vapeur d'eau de l'air, ainsi que les gaz acides tels que le dioxyde de carbone. L'hydroxyde de sodium est l'un des produits chimiques les plus couramment utilis\u00e9s. Il est largement utilis\u00e9 et constitue une substance n\u00e9cessaire dans de nombreux processus industriels.<\/p>\n

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

Il est utilis\u00e9 dans la production de papier et de p\u00e2te de cellulose ; il est \u00e9galement utilis\u00e9 dans la production de savon, de d\u00e9tergents synth\u00e9tiques, d'acides gras synth\u00e9tiques et dans le raffinage d'huiles animales et v\u00e9g\u00e9tales.<\/p>\n

Il est utilis\u00e9 dans l'industrie textile et de la teinture comme agent d'encollage, agent de d\u00e9capage et agent de mercerisage pour les tissus de coton.<\/p>\n

Il est utilis\u00e9 dans l'industrie chimique pour la production de borax, de cyanure de sodium, d'acide formique, d'acide oxalique, de ph\u00e9nol, etc. Il est utilis\u00e9 dans l'industrie p\u00e9troli\u00e8re pour le raffinage des produits p\u00e9troliers et dans les boues de forage des puits de p\u00e9trole.<\/p>\n

Il est \u00e9galement utilis\u00e9 dans la production d'alumine, le traitement de surface du zinc m\u00e9tallique et du cuivre m\u00e9tallique, ainsi que dans le verre, l'\u00e9mail, le cuir, la m\u00e9decine, les colorants et les pesticides.<\/p>\n

Il est utilis\u00e9 comme neutralisant d'acide dans l'industrie alimentaire, comme agent d'\u00e9pluchage pour les agrumes et les p\u00eaches, comme d\u00e9tergent pour les bouteilles et les bo\u00eetes de conserve vides, et comme d\u00e9colorant et d\u00e9sodorisant.<\/p>\n

Il s'agit d'un r\u00e9actif analytique de base largement utilis\u00e9. Il sert \u00e0 pr\u00e9parer des solutions alcalines standard pour l'analyse. Il absorbe une petite quantit\u00e9 de dioxyde de carbone et d'eau. Il est utilis\u00e9 pour la neutralisation des acides. Il est utilis\u00e9 pour la production de sel de sodium. Il est largement utilis\u00e9 dans la fabrication du papier, l'industrie chimique, la teinture, la m\u00e9decine, la m\u00e9tallurgie (fusion de l'aluminium), les fibres chimiques, la galvanoplastie, le traitement de l'eau, le traitement des gaz d'\u00e9chappement, etc.<\/p>\n

Il est utilis\u00e9 comme agent neutralisant, agent masquant, pr\u00e9cipitant, agent masquant pr\u00e9cipitant, r\u00e9v\u00e9lateur de couleur pour la d\u00e9termination des c\u00e9tost\u00e9ro\u00efdes par analyse en couche mince. Il est utilis\u00e9 pour la production de sel de sodium et la saponification. Il est utilis\u00e9 pour la production de divers sels de sodium, de savon, de p\u00e2te \u00e0 papier, de finition de tissus de coton, de soie, de fibres de viscose, de r\u00e9g\u00e9n\u00e9ration de produits en caoutchouc, de nettoyage de m\u00e9taux, de galvanoplastie, de blanchiment, etc.<\/p>\n

Dans les cr\u00e8mes cosm\u00e9tiques, ce produit et l'acide st\u00e9arique, etc. subissent une saponification pour agir comme \u00e9mulsifiants, utilis\u00e9s pour la fabrication de cr\u00e8me \u00e0 neige, de shampoing, etc.<\/p>\n

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

Il doit \u00eatre stock\u00e9 dans un entrep\u00f4t frais, sec et bien ventil\u00e9. Il doit \u00eatre tenu \u00e0 l'\u00e9cart des sources de feu et de chaleur. La temp\u00e9rature de l'entrep\u00f4t ne doit pas d\u00e9passer 35\u2103, et l'humidit\u00e9 relative ne doit pas d\u00e9passer 80%. L'emballage doit \u00eatre scell\u00e9 et ne doit pas \u00eatre humide. Il doit \u00eatre stock\u00e9 s\u00e9par\u00e9ment des substances inflammables (ou combustibles) et des acides, et ne doit pas \u00eatre m\u00e9lang\u00e9.<\/p>","protected":false},"excerpt":{"rendered":"
