Qhib alumina muaj ntau lub zog. Alumina qhib siv tau los ua desiccant, adsorbent, fluoride tshem tawm tus neeg sawv cev, catalyst cab kuj, thiab lwm yam alumina yog ua los ntawm alumina tom qab kub kub kub, nrog ntau cov micropores saum npoo thiab tsim cov pores sab hauv. Nws muaj muaj zog adsorptivity, thiab aluminium ions yog cov tshuaj ruaj khov heev, yog li ua kom alumina tseem ruaj khov thaum adsorbed, thiab yuav tsis hnov mob nrog lwm yam.
Kev siv alumina feem ntau yog siv rau huab cua kom qhuav ntawm lub tshuab cua kom qhuav, roj kom qhuav ntawm cov twj paj nruag thiab ntsuas, thiab cua qhuav ntawm cov tub yees hauv cov tshuab nqus dej kom qhuav. Qhov loj me me uas tsim nyog ua tiav ntawm alumina rau kev ua kom cua qhuav?
Cov tshwj xeeb ntawm kev ua kom rov qab alumina tau faib ua 1-2 hli, 3-5 hli, 4-6mm, 5-8mm thiab lwm tus. Daim ntawv thov cov ntau qhov ntau thiab tsawg yog txawv. 3-5 hli tshuab txais alumina feem ntau siv rau huab cua kom qhuav thiab ua kom huv. Yog tias lub vijtsam muaj qhov sib txawv loj, 5-8mm tshuab txais alumina tuaj yeem siv rau qhov qis qis thiab 3-5mm tshuab txais alumina rau sab saud, uas yog qhov muaj txiaj ntsig zoo rau cov cua ncig thiab adsorption.
Lub particle loj ntawm activated alumina rau kev kho dej fluoride tshem tawm tus neeg sawv cev yog 1-2mm. Qhov me dua qhov loj me me, qhov zoo dua rau cov nyhuv defluorination ntawm qhib alumina. Cov cheeb tsam hauv cheeb tsam tshwj xeeb yog loj thiab qhov pores sab hauv muaj ntau. Qhib alumina muaj zoo tshaj plaws adsorption kev ua tau zoo. Nws piv rau cov roj carbon activated. Thaum peb siv alumina ua kom lub cev tshem tawm cov tshuaj fluoride, peb yuav tsum xaiv lub npe alumina uas tau qhib ua tshiab, uas yog alumina ua kom rov qab qhib dua.
Lub teeb alumina no muaj adsorption kev ua tau zoo thiab yuav tsis yaj cov tshuaj phem, thiab tsis tuaj yeem xaiv cov tshuaj alumina ua kom rov ua haujlwm. Cov adsorption kev ua tau zoo ntawm txhuas thiab ua kom rov ua haujlwm alumina tsis ruaj khov. Nyob rau tib lub sijhawm, nws yuav ua teeb meem rau cov dej tsis zoo vim yog cov adsorption ntawm cov roj cua tsis zoo, yog li qhov no yuav tsum lees paub.
