Ukusabela kweI-Antimony Pentoxide Powder
Uma ishisiswe ngo-700°C i-pentoxide ephuzi e-hydrated iguqulela ekubeni okuqinile okumhlophe okunganamanzi ngefomula ethi Sb2O13 equkethe kokubili i-Sb(III) kanye ne-Sb(V). Ukushisa ku-900 ° C kukhiqiza impushana emhlophe engancibiliki ye-SbO2 yazo zombili izinhlobo ze-α kanye ne-β. Ifomu elithi β liqukethe i-Sb(V) ku-octahedral interstices kanye namayunithi e-pyramidal Sb(III) O4. Kulezi zinhlanganisela, i-athomu ye-Sb(V) ixhunywe nge-octahedral kumaqembu ayisithupha -OH.

Imininingwane yokupakisha: Isisindo esiphelele somugqa wekhadibhodi singu-50 ~ 250KG noma ulandele izidingo zekhasimende
Isitoreji Nezokuthutha:
Indawo yokugcina impahla, izimoto kanye neziqukathi kufanele zigcinwe zihlanzekile, zomile, zingenawo umswakama, ukushisa futhi zihlukaniswe nezindaba ze-alkaline.
YiniI-Antimony Pentoxide Powderusetshenziselwe?
I-Antimony Pentoxideisetshenziswa njenge-Flame retardant engutsheni. Ithola ukusetshenziswa njenge-flame retardant ku-ABS nakwamanye amapulasitiki futhi njenge-flocculant ekukhiqizeni i-titanium dioxide, futhi ngezinye izikhathi isetshenziselwa ukukhiqizwa kwengilazi, upende. Iphinde isetshenziswe njenge-ion exchange resin enanini lama-cations esixazululweni esine-acidic okuhlanganisa i-Na+ (ikakhulukazi ekugcinweni kwayo okukhethiwe), nanjenge-polymerization kanye ne-oxidation catalyst.
