Activated alumina kev loj hlob

Tam sim no, activated alumina, ua cov khoom tseem ceeb heev, tau siv dav hauv ntau yam kev lag luam. Nws daim ntawv thov muaj feem xyuam nrog ntau thaj chaw xws li hlau, cov khoom siv hauv tsev, cov tshuaj zoo, thiab lwm yam, thiab yog siv dav hauv catalysis, adsorption, sib cais, thermal stability, nplaim taws retardancy, thiab lwm yam. mus rau kev lag luam kev tshawb fawb, qhov nruab nrab txhua xyoo kev loj hlob tus nqi ntawm activated alumina yuav tsum nyob twj ywm ntawm 5%-8%. Tam sim no, lub khw muag khoom alumina tau dhau los ntawm theem ntawm kev tsim kho tshiab thiab kev hloov kho thev naus laus zis. Nyob rau hauv xyoo tas los no, ntau lub tuam txhab tau ua tiav cov khoom tshiab tshawb fawb thiab kev tsim kho thiab kev tsim kho tshiab ntawm activated alumina los txhim kho cov khoom zoo. Tshwj xeeb tshaj yog nyob rau hauv cov teb ntawm siab purity thiab refinement, tshiab activated alumina cov khoom raug tsim thiab txhawb. Kev tshawb fawb thiab kev txhim kho ntawm cov thev naus laus zis tshiab no tsis yog tsuas yog txhawb kev txhim kho ntawm kev ua lag luam alumina, tab sis kuj tseem txhawb kev txhim kho ntawm cov txheej txheem ntawm tag nrho cov kev lag luam. Nyob rau tib lub sijhawm, nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev loj hlob ntawm kev lag luam thoob ntiaj teb kev lag luam, kev lag luam thoob ntiaj teb rau cov khoom siv alumina kuj tau pib nkag mus rau lub sijhawm ntawm kev loj hlob sai. Tshwj xeeb tshaj yog nyob rau hauv industrialized lub teb chaws, qhov kev thov rau activated alumina yog loj heev. Piv txwv li, kev lag luam hauv Tebchaws Meskas, Nyiv, Europe thiab lwm lub tebchaws yog qhov dav heev, thiab qhov kev thov nce ntxiv. Ntawm ib sab, cov teb chaws no tau lees paub qhov tseem ceeb ntawm kev tiv thaiv ib puag ncig dej thaum ntxov, thiab ntawm qhov tod tes, lawv kuj tau ua qee yam kev vam meej hauv kev tiv thaiv ib puag ncig. Daim ntawv thov ntawm activated alumina kuj tau siv dav hauv cov tebchaws no, ua rau muaj txiaj ntsig zoo rau lub ntiaj teb kev tiv thaiv ib puag ncig. Nyob rau hauv dav dav, activated alumina, raws li ib tug dav siv cov khoom tseem ceeb, tsis yog tsuas yog cuam tshuam los ntawm kev loj hlob ntawm domestic kev lag luam, tab sis kuj los ntawm lub thoob ntiaj teb kev lag luam. Nyob rau hauv lub neej yav tom ntej, kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho ntawm ib puag ncig kev paub yuav ntxiv txhawb kev txhim kho thiab kev tsim kho tshiab ntawm kev lag luam activated alumina. Cov tuam txhab lag luam yuav tsum tau txhim kho cov theem kev txawj ntse thiab kev tsim kho tshiab ntawm cov khoom kom tau raws li qhov xav tau ntawm kev ua lag luam.
