Alumina yakozwe

Alumina ikora (formula ya molekyuli Al2O(3-x)(OH)2x,0

Alumina ikoreshwa cyane mu bikoresho by'ubutare, gutunganya amavuta, ibikoresho by'ikoranabuhanga, ethylene, propylene, umwuka n'ibindi byuma byumisha, yakoreshejwe mu nganda nyinshi za hydrogen peroxide, mu nganda zifumbira, mu nganda zitunganya ogisijeni n'ibikoresho byo gutunganya peteroli, kandi yageze ku musaruro mwiza. Umupira wa alumina ukoreshwa kandi ukurikije polarity ya adsorbent kugira ngo umenye imbaraga z'amazi, oxyde, aside asetiki, alkali n'izindi affinity zikomeye, ni desiccant igabanya ubushyuhe, inyuzwa mu myenge ya polar adsorbent. Ishobora gukoreshwa cyane mu kumisha cyane gaze ya peteroli, gaze ya ethylene propylene, ikorwa rya hydrogen, igikoresho cyo gutandukanya umwuka, imashini yumisha umwuka, fluoride muri peroxide ya hydrogen, ishobora kandi gukuraho gaze ya sulfur hidrojeni, dioxyde de carbone, fluoride ya hydrogen, hidrojeni hidrojeni, hidrokaboni n'ibindi bihumanya muri gaze y'imyanda, cyane cyane ikwiriye amazi arimo fluorine.

Alumina ikora ni agace k'umweru cyangwa gato k'umutuku muto, ifite ubwoya bwinshi kandi ikora neza, ifite ubushobozi bwo gucunga amazi maremare ya fluorine, irakora neza, yoroshye kongera kuvugurura, ibiyigize ni bike, uretse abakoresha amazi yo kunywa uretse fluorine, iracyashobora gukoreshwa nk'inyunganizi, desiccant na catalyst carrier. Ikoreshwa cyane mu buhanga bw'amazi yo mu robine, mu buhanga bwo gusukura amazi, mu ruganda rwa hydrogen peroxide, mu ruganda rw'ifumbire, mu ruganda rwa ogisijeni no mu nganda za peteroli. Alumina ikora ifite ubushobozi bwo gutera, ikora imyenge, ikwirakwira cyane, ahantu hanini ha alumina, ikwiriye ubwoko butandukanye bwa gaze n'amazi yumisha, ikoreshwa mu kumisha amazi n'ibikoresho by'inganda, ikoreshwa mu gusukura amazi, gukuraho fluorine, dearsenization, gukuraho ibara ry'amazi mabi, gukuraho impumuro mbi n'ibindi. Iki gicuruzwa gikozwe muri alumina isuku cyane binyuze mu gutegura siyansi no kurangiza catalytic. Ikoreshwa nk'inyunganizi, desiccant, catalyst na catalyst mu bikorwa byinshi byo gusubiza nk'amavuta, ifumbire mvaruganda n'inganda za shimi. Dukurikije uko ikoreshwa, ishobora kugabanywamo: alumina ikora asorbent, desiccant na catalyst carrier.

Alumina ikora ikozwe muri alumina ifite isuku nyinshi binyuze mu gutegura siyansi no kurangiza neza. Uduce tw’umweru dufite imyenge, ingano y’uduce ingana, ubuso bworoshye, imbaraga za mekanike, hygroscopicity ikomeye, nyuma yo kwinjiza amazi ntiyongera kandi ntigasenya ibintu by’umwimerere, bitari uburozi, nta buryohe, nta mpumuro, ntashongesha mu mazi no mu binyabutabire by’umwimerere. Ni molekile ifite ubuso bunini bwihariye. Iyo agaciro ka PH n’ubutare bw’amazi ari hasi, ubushobozi bwo gukuraho fluorine buri hejuru ya 3.0mg/g. Ishobora gukoreshwa mu mazi yo kunywa no mu bikoresho by’inganda, dearsenic, decolorization y’imyanda, deodoration, nibindi. Ibicuruzwa by’ingenzi ni: activated alumina fluoride remover, activated alumina desiccant, activated alumina catalyst, hydrogen peroxide special activated alumina alumina.

Desiccant ya alumina ikora: iki gicuruzwa ni ubwoko bw'ibikoresho bifite imyenge mito n'izunguruka, bifite ubushobozi bukomeye bwo kuvoma, ubuso bunini bwihariye, gukomera cyane, igihe kirekire, kandi gishobora gukoreshwa kenshi hakoreshejwe uburyo bwo kuvugurura. Iki gicuruzwa ni umweru, gifite imyenge izunguruka, ntigihumanya, ntikigira impumuro, ntigishongesha mu mazi. Gikoreshwa cyane mu nganda za peteroli, inganda za shimi, inganda z'imyenda, inganda za zahabu n'izindi nganda, nko kumisha ibikoresho mu muyaga, igikoresho cyo gutandukanya umwuka gikoresha ingufu, aho amazi anyura hashobora kugera kuri dogere zirenga -41, kandi gishobora no gukoreshwa mu byuma, gaze isesa peteroli, ethylene, propylene mu gice cy'amazi no mu gice cya gaze.
