Cov tshuaj alumina muaj ntau yam, raws li tus qauv kev lag luam hlau tsis yog ferrous YS / ton 619-2007 "hom tshuaj alumina thiab hom npe", raws li cov tshuaj lom neeg ntawm cov tshuaj alumina tau muab faib ua 5 pawg: aluminium hydroxide series, tshwj xeeb aluminium oxide series, quasi thin alumina series, zeolite series thiab calcium aluminate cement series.
Tam sim no, polyaluminium chloride, sodium silicate, fluoride ntsev thiab lwm yam ntsev txhuas, sodium aluminate, gallium thiab gallium compounds, ib feem ntawm alumina ceramics thiab corundum refractories kuj suav nrog hauv pawg ntawm tshuaj alumina.
Xyoo 1910, Alcoa tau tsim thiab muag thawj pawg ntawm calcined alumina hauv ntiaj teb, uas yog cov khoom siv raw rau kev tsim cov khoom siv corundum dawb.
Tshuaj alumina yog tus cwj pwm los ntawm ntau yam khoom, muaj nqis ntxiv, cov ntsiab lus siab, cov teb thov dav thiab nthuav dav, tus nqi ruaj khov, tus phooj ywg ib puag ncig, yog li ntawd, tau dhau los ua ib ceg tseem ceeb ntawm kev lag luam txhuas.
Ntau lub teb chaws hauv ntiaj teb tau nqis peev ntau heev rau kev txhim kho kev lag luam tshuaj alumina. Alcoa tau siv los ua lub ntiaj teb tus tsim tshuaj alumina loj tshaj plaws, nrog 24 lub tuam txhab tsim khoom, npog txhua lub teb chaws thiab thaj chaw loj hauv ntiaj teb, tsim ntau dua 220 hom thiab ntau dua 1000k tons / a. Tom qab ntawd xyoo 2007 lub phaj tshuaj alumina tau hloov mus rau lub tuam txhab Netherlands anmai.
Nyiv yog lub ntiaj teb lub zog loj tshaj plaws hauv kev tsim cov tshuaj alumina, kev siv, cov zis ntawm kwv yees li 1000 k, 2012 tons, thiab txuas ntxiv mus qeeb qeeb, ntau yam yog lub ntiaj teb feem ntau, Nyiv tsis tsim cov tshuaj alumina qib metallurgical, tab sis tau pom qhov ntsuas hauv kev tsim tshuaj alumina, seriation, kev tshawb fawb thiab thev naus laus zis siab, kev tiv thaiv ib puag ncig thiab kev siv nyiaj txiag, cov khoom tsuas yog ua kom tau raws li kev thov hauv tsev, kev xa khoom mus txog 25%. Ntau tshaj 85% ntawm Nyiv cov tshuaj alumina tsim tawm yog tsim los ntawm Sumitomo kev lag luam tshuaj, Showa Denko thiab Nyiv lub teeb hlau.
Nyob ib ncig ntawm xyoo 1940, Tebchaws Meskas, Nyiv Pooj thiab Tebchaws Europe tau tshawb nrhiav txog tshuaj lom neeg alumina ntau heev, thiab xyoo 1970, qee lub tebchaws muaj kev lag luam loj hlob tau muaj kev loj hlob zoo hauv txawv teb chaws.
Raws li cov ntaub ntawv ntawm lub koom haum kev lag luam txhuas thoob ntiaj teb, xyoo 1975, tag nrho cov khoom tsim tawm ntawm alumina hauv cov teb chaws sab hnub poob yog li ntawm 20344k tons, tshuaj alumina tsim tawm ntawm 1699k tons, suav txog 8.3% ntawm tag nrho cov khoom tsim tawm; Xyoo 2000, tag nrho cov khoom tsim tawm thoob ntiaj teb alumina yog li ntawm 51200k tons, thaum cov tshuaj alumina tsim tawm yog 4800k tons, suav txog 9.4% ntawm tag nrho cov khoom tsim tawm. Xyoo 2008, cov khoom tsim tawm thoob ntiaj teb ntawm cov hlau alumina qib yog 60496k tons thiab tshuaj alumina yog 4638k tons, suav txog 7.12% ntawm tag nrho cov khoom tsim tawm. Xyoo 2012, tag nrho cov khoom tsim tawm ntawm alumina hauv ntiaj teb yog 95,705k tons, thiab cov khoom tsim tawm ntawm tshuaj alumina yog 85,80k tons, suav txog 9% ntawm tag nrho cov khoom tsim tawm. Txij xyoo 2008 txog 2012, qhov nruab nrab txhua xyoo kev loj hlob ntawm tshuaj alumina thoob ntiaj teb yog 16.6%, txog 11 feem pua ntawm cov ntsiab lus siab dua li qhov nruab nrab txhua xyoo kev loj hlob ntawm cov txhuas thawj zaug.
Kev lag luam alumina tshuaj lom neeg hauv Suav teb tau pib lig heev. Nyob ib ncig ntawm xyoo 1961, txhawm rau daws qhov tsis txaus ntawm cov khoom siv raw hauv kev lag luam hluav taws xob, Shandong Aluminium Hoobkas (tam sim no hu ua Shandong Aluminium Industry Co., LTD.) thawj zaug tsim cov alumina sodium qis thiab pib tshawb fawb, kev txhim kho thiab kev tsim cov alumina tshuaj lom neeg hauv Suav teb.
Xyoo 1970, txhawm rau kom ua tau raws li qhov xav tau ntawm cov roj av, tshuaj lom neeg, refractories, ceramics, tshuaj, kev tiv thaiv ib puag ncig, riam phom, aerospace thiab lwm yam kev lag luam, Shandong aluminium cog, Zhengzhou lub teeb hlau tshawb fawb lub koom haum thiab tau tsim thiab tsim cov alumina activated, alumina arsenic fluoride tshem tawm tus neeg sawv cev, hlau qis aluminium hydroxide, alumina purity siab, ceramics nrog alpha Al2O3, txau nrog alumina thiab lwm yam 24 hom khoom tshiab.
Xyoo 1980, Tuam Tshoj txoj kev tsim tshuaj alumina tau nkag mus rau lub sijhawm ntawm kev txhim kho sai, thiab cov khoom tshiab tau tshwm sim. Sawv cev los ntawm zhengzhou lub teeb hlau tshawb fawb lub koom haum, shandong txhuas kev lag luam co., ltd. thiab Tuam Tshoj Great Wall txhuas kev lag luam co., ltd. kwv yees li 60 kab tsim tshuaj alumina tshwj xeeb tau tsim. Hauv ntau lub tuam txhab alumina loj hauv thaj chaw ib puag ncig tau tsim cov tshuaj alumina ntau lawm ntawm cov tuam txhab ntiag tug, lawv siv cov khoom siv hauv tsev lossis xa tawm los tsim ntau yam tshuaj alumina.
Tuam Tshoj yog lub teb chaws loj tsim alumina, siv ntau yam thev naus laus zis ntau dua li lwm lub teb chaws, nws yooj yim kom paub txog cov kab ntawm cov tshuaj alumina los ntawm kev sib txuas hauv cov txheej txheem thev naus laus zis, tshwj xeeb tshaj yog txhuas hydroxide tsim los ntawm cov txheej txheem sintering, uas muaj qhov dawb huv siab.
Tom qab ntau tshaj 50 xyoo ntawm kev txhim kho, Tuam Tshoj txoj kev lag luam tshuaj alumina muaj kev cuam tshuam loj heev hauv kev lag luam hauv tsev thiab txawv teb chaws, cov khoom siv aluminium hydroxide thiab lwm yam khoom kuj paub zoo hauv kev lag luam thoob ntiaj teb.
Txawm li cas los xij, piv rau Tebchaws Meskas, Lub Tebchaws Yelemees, Nyiv, Tuam Tshoj cov tshuaj alumina tsis hais txog cov khoom zoo, ntau yam, thiab qhov ntau lawm muaj qhov sib txawv loj, qhov laj thawj tseem ceeb yog qhov rov qab los ntawm kev siv tshuab thiab khoom siv ntau lawm, kev tsim khoom thiab kev siv cov kev tshawb fawb theoretical yooj yim tsis txaus, lub peev xwm tsim kho tshiab tsis muaj zog, kev txhim kho kev lag luam tsis txaus.
