Yini iziI-Barium Hydroxide ne-Barium Hydroxide Octahydrateusetshenziselwe?
Ngokwezimboni,i-barium hydroxideisetshenziswa njengesandulela kwezinye izinhlanganisela ze-barium. I-monohydrate isetshenziselwa ukukhipha amanzi futhi isuse i-sulfate emikhiqizweni ehlukahlukene. Njengoba kusetshenziswa ilabhorethri, i-Barium hydroxide isetshenziswa kukhemistri yokuhlaziya ukuze kuncishiswe ama-asidi abuthakathaka, ikakhulukazi ama-organic acid.I-Barium hydroxide octahydrateisetshenziswa kakhulu ekwenzeni usawoti we-barium kanye ne-barium organic compounds; njengesengezo embonini ye-petroleum; Ekwenziweni kwe-alkali, ingilazi; ku-vulcanization yerabha yokwenziwa, kuma-corrosion inhibitors, izibulala-zinambuzane; ikhambi lesikali se-boiler; Ama-boiler cleaners, embonini kashukela, alungisa amafutha ezilwane nemifino, athambise amanzi, enze izibuko, apende uphahla; I-Reagent yegesi ye-CO2; Isetshenziselwa ukufakwa kwamafutha kanye nokuncibilikisa i-silicate.
