Daim ntawv thov ntawm activated alumina ceramic pob khoom

HUAO yog ib lub chaw muag khoom zoo tshaj plaws ntawm alumina ceramic pob, uas tuaj yeem muab cov pob zeb ceramic ntawm ntau qhov ntau thiab tsawg. HUAO yuav qhia txog daim ntawv thov ntawm activated alumina ceramic pob khoom hauv qab no.

Activated alumina ceramic balls tseem hu ua activated alumina. Lub alumina siv nyob rau hauv lub catalyst feem ntau hu ua activated alumina. Nws yog ib qho ntxeem tau, cov khoom tawg yooj yim heev nrog thaj tsam loj thiab microporous nto. Nws muaj cov khoom tsim nyog rau catalysis, xws li adsorption kev ua tau zoo, kev ua haujlwm saum npoo, zoo thermal stability, thiab lwm yam, yog li nws yog dav siv los ua catalyst thiab catalyst cab kuj rau cov tshuaj tiv thaiv.

Daim ntawv thov ntawm activated alumina ceramic pob khoom:

Hauv petrochemical thiab chiv kev lag luam, nws yog dav siv los ua catalyst thiab catalyst cab kuj. Activated alumina kuj muaj cov khoom adsorption, yog li nws yog siv los ua ib qho desiccant rau roj thiab kua, adsorbent rau roj purification, defluorinating tus neeg sawv cev rau cov dej haus, thiab xim thiab ntxhiab tshem tawm rau cov dej phwj tuaj.

Activated alumina ceramic balls tuaj yeem siv ua ke nrog lub tog raj kheej defluorination hauv tsev, thiab yog cov dej haus zoo tshaj plaws defluorination hauv tsev. Cov khoom siv lim dej defluorination no tuaj yeem siv ua ke nrog cov khoom siv defluorination ntawm cov nroj tsuag dej lossis cov khoom siv defluorination. Ua kom cov khoom siv lim dej defluorination rau cov khoom siv hauv tsev defluorination: teeb tsa cov tshuaj txhuas sulfate (3 litres dej, 0.3kg khoom aluminium sulfate), muab cov khoom lim alumina defluorination rau hauv cov tshuaj saum toj no, tsau rau 5-10 sij hawm thiab muab pov tseg cov dej so so (soaking). Nws yuav tsum tau nplawm kom zoo), thiab tom qab ntawd ntxuav nrog dej rau 3-5 zaug, kwv yees li 2 litres dej txhua lub sijhawm, lossis rov tsim dua los ntawm kev hloov kho pH, thiab pH tus nqi yog tswj ntawm 7.5.

Cov khoom siv ua kom muaj alumina ceramic pob defluorination lim tuaj yeem siv tsis tu ncua rau 6-8 xyoo. Thaum lub ntsej muag tshwm daj xim av, cov nyhuv defluorination txo qis, uas yog tshwm sim los ntawm cov pa phem ntawm impurities hauv dej. Yog li ntawd, nws raug kho nrog 3 feem pua ​​​​ dilute hydrochloric acid txhua rau lub hlis. Txoj kev ua haujlwm yog tib yam li txoj kev tsim kho dua tshiab.
