Ndi chiyaniBarium Hydrooxide ndi Barium Hydrooxide Octahydratekugwiritsidwa ntchito?
Industrially,barium hydroxideamagwiritsidwa ntchito ngati kalambulabwalo wa mankhwala ena a barium. The monohydrate ntchito dehydrate ndi kuchotsa sulphate zosiyanasiyana mankhwala. Monga momwe labotale imagwiritsira ntchito, Barium hydroxide imagwiritsidwa ntchito poyesa chemistry kuti ipangitse ma acid ofooka, makamaka ma organic acid.Barium hydroxide octahydrateamagwiritsidwa ntchito kwambiri popanga mchere wa barium ndi barium organic compounds; monga chowonjezera mu makampani a petroleum; Popanga alkali, galasi; mu kupanga mphira vulcanization, mu corrosion inhibitors, mankhwala ophera tizilombo; mankhwala a boiler; Otsuka ma boiler, m'makampani a shuga, amakonza mafuta a nyama ndi masamba, kufewetsa madzi, kupanga magalasi, kujambula denga; Reagent ya CO2 gasi; Amagwiritsidwa ntchito popanga ma deposits amafuta ndi silicate smelting.
