ChiiBarium Hydroxide uye Barium Hydroxide Octahydratekushandiswa?
Industrially,barium hydroxideinoshandiswa semutangiri kune mamwe makemikari e-barium. Iyo monohydrate inoshandiswa kuderedza mvura uye kubvisa sulfate kubva kune zvakasiyana-siyana zvigadzirwa. Sekushandiswa kwerabhoritari, Barium hydroxide inoshandiswa mukuongorora kemikari yekutarisa kwemaasidhi asina simba, kunyanya maasidhi eorganic.Barium hydroxide octahydrateinoshandiswa zvakanyanya mukugadzirwa kwebarium salts uye barium organic compounds; sekuwedzera muindasitiri yepetroleum; Mukugadzira alkali, girazi; mu synthetic rubber vulcanization, mune corrosion inhibitors, mishonga yezvipembenene; boiler scale remedy; Boiler cleaners, muindasitiri yeshuga, gadzirisa mafuta emhuka nemiriwo, nyorovesa mvura, gadzira magirazi, penda sirin'i; Reagent ye CO2 gasi; Inoshandiswa kune mafuta deposits uye silicate smelting.
