Zinc oxide yog ib qho tseem ceeb inorganic compound dav siv hauv kev lag luam xws li roj hmab, ceramics, coatings, thiab kws tshuaj. Nws cov khoom lag luam feem ntau poob rau hauv ob pawg: cov txheej txheem tsis ncaj (Fabkis txheej txheem) thiab cov txheej txheem ncaj qha (Waelz txheej txheem), nrog rau kev xaiv nyob ntawm cov khoom siv raw thiab cov khoom siv purity.
Cov txiaj ntsig tseem ceeb ntawm Cov Txheej Txheem Ncaj Ncees Zinc Oxide: Tus nqi -Kev ua tau zoo thiab cov khoom siv raw khoom yooj yim
Raws li ib tug thawj coj ntawm thermal daws, Jiangsu Jufeng Thermal Technology Co., Ltd.Cov txheej txheem ncaj qha (rotary kiln) zinc oxide ntau lawm. Txoj kev no, tshwj xeeb tshaj yog covCov txheej txheem Waelz, yog renowned rau nws exceptionalraw khoom adaptabilitythiabnqi efficiency. Nws tuaj yeem ua cov ntim loj ntawm ntau yamzinc-cov khoom pov tseg(xws li smelting plua plav thiab leaching residues) thiab qis-qib zinc ores, ua rau nws yog ib qho tseem ceeb thev naus laus zis rau kev rov ua dua tshiab.
Paub meej cov kauj ruam ntawm Direct Process Rotary Kiln Production
1.Kev npaj raw khoom
Zinc ores los yog zinc-muaj cov khib nyiab yog crushed thiab hauv av kom haum particle loj (feem ntau yog 80-100 mesh) kom ntseeg tau tias muaj kev sib haum xeeb.
2.Sib tov thiab sib tov
Cov txheej txheem zinc- cov khoom siv bearing yog sib xyaw ua ke nrog cov reductant (xws li, coke hmoov, anthracite thee) los tsim cov khoom noj.
3.Txo thiab Calcination
Cov khoom noj sib xyaw yog pub rau hauv ib qho inclined rotary kiln. Nyob rau hauv qhov siab - qhov kub thiab txias (1000-1300 degree), zinc oxide nyob rau hauv pub yog txo los ntawm carbon los ua metallic zinc vapor.
4.Oxidation thiab Collection
Cov zinc vapor mus nrog cov roj ntws mus rau qhov kawg ntawm qhov cub, qhov twg nws nrawm heevoxidizedThaum sib cuag nrog cov cua tshaj tawm, tsim cov zinc oxide zoo. Cov pa roj flue ces dhau los ntawm ntau lub- tube txias rau qhov pib daws, ua raws li kev ntes tau zoo hauvloj baghouse plua plav collectorkom tau txais cov khoom siv zinc oxide kawg.
5.Kev Tiv Thaiv Ib puag ncig thiab Los ntawm -Kev kho cov khoom
Kev tsim tawm - roj yog kho los ntawm kev ua tiav raupov tseg tshav kub rov qab, desulfurization, denitrification, thiab kev tshem tawm cov plua plav siab heev, kom ntseeg tau raws li emissions. Lub kiln residue raug soj ntsuam raucov ntaub ntawv rov qab los yog pov tseg nyab xeeb, ua kom huv huv ntau lawm.
Cov yam ntxwv ntawm cov khoom thiab kev siv cov txheej txheem ncaj qha Zinc Oxide
Zinc oxide tsim los ntawm txoj kev no muaj ntau yam purity ntau (Feem ntau 90% -99%), ntsib ntau yam kev xav tau kev lag luam. Nws yog feem ntau siv rau hauv ceramic glazes, cov khoom siv roj hmab dav dav, kev tsim iav, thiab qee yam kev siv tshuaj, qhov uas nws muaj cov nqi zoo tshaj - kev ua tau zoo.
Piv txwv li,indirect txheej txheem zinc oxidesiv siab -purity zinc ingots li feedstock, yielding khoom nrog purity tshaj 99.7%. Nws feem ntau ua haujlwm siab -kawg daim ntawv thov xws li cov roj hmab zoo tshaj plaws, tshuaj, thiab khoom siv hluav taws xob, qhov uas qhov kev coj dawb huv yog qhov tseem ceeb.
