Activated alumina pobyog spherical cov khoom tsim los ntawm alumina micronized hmoov tom qab qee cov txheej txheem tshwj xeeb. Cov txheej txheem ntau lawm ntawm activated alumina npas yog qhov tseeb tsis nyuaj, nrog aluminium hydroxide raws li cov khoom siv raw los ntawm kev kho kom qhuav - crushing - ceev desiccation - pob ua - solidification - nquag roasting - kuaj thiab ntim thiab lwm yam txheej txheem kom tiav. Cov kauj ruam tshwj xeeb tau piav qhia hauv qab no.
1, Aluminium hydroxide ziab kom qhuav: aluminium hydroxide raw cov ntaub ntawv nrog 7 feem pua -8 feem pua ya raws, yuav tsum tau nce qhov kub ntawm 150-200 degree kom evaporate cov adhering noo noo.
2, Aluminium hydroxide crushing: kev kho kom qhuav ua ntej cov khoom siv raw rau hauv cov cuab yeej siv tshuab zeb yuav raug crushed cov ntaub ntawv, crushing particle loj yuav tsum tau kho raws li cov kev xav tau ntawm kev tsim, feem ntau ua pob loj faib manipulation nyob rau hauv 325 mesh - 500 mesh los yog li ntawd.
3, Aluminium hydroxide ceev desiccation: los ntawm ntab roasting ceev desiccation, thiab excitation txias system. Qhov ntsuas kub ntawm qhov ceev ceev desiccation industrial kiln yog 800-900 degree , thiab qhov kub ntawm qhov nkag thiab tawm ntawm lub qhov cub hluav taws xob yog 410-460 degree .
4, Pob kev ua: Cov txheej txheem no yog qhov tseem ceeb txuas cov khoom lag luam, ceev ceev, kev sib tsoo lub zog, qhov chaw tshwj xeeb, pore ntim loj.
5, Activated roasting: Tom qab lub pob ua cov txheej txheem, nws nkag mus rau cov txheej txheem ua kom tiav, thiab tom qab lub pob ua haujlwm raug daws, nws tau hloov mus rau qhov kub siab 90-100 degree chav solidification, thiab lub sij hawm solidification yog 4-6 teev. Tom qab ntawd mus rau hauv lub qhov cub ntsug rau cov txheej txheem roasting, roasting kub ntawm 400-450 degree, roasting lub sij hawm ntawm 40-45 feeb.
6, Tom qab ua tiav ntawm kev ua haujlwm ntau lawm, kev tshuaj xyuas tawm ntawm cov lus qhia tshwj xeeb ntawm lubactivated alumina pob, cov khoom particle loj tis yog uniform thiab tsis muaj pob tawg tuaj yeem ntim rau hauv lub tsev rau khoom.
