Light-fired magnesia hmoov yog ib hom khoom siv raw li nruab nrab thiab tshuaj lom neeg. Nws yog siv nyob rau hauv lwm yam kev lag luam dua li cov ntaub ntawv refractory thiab cementitious. Tsis tas li ntawd, kev loj hlob ntawm converter slag splashing technology tau ntxiv txhab daim ntawv thov ntawm lub teeb hlawv magnesia hmoov. Tam sim no, lub tshuab slag siv hluav taws xob feem ntau siv cov hluav taws kub ua ntxhua los ua cov hmoov pob zeb, xws li cov hluav taws kub pwm paug, cov kab mob uas muaj tsos mob uas muaj roj thiab cov kab uas muaj carbon-calcium uas muaj tsos mob uas muaj tsos hlau nplaum.
Cov tshuaj tua hluavtaws magnesia hmoov, uas yog hu ua lub teeb ci nqaij hlav magnesia hmoov, yog ib hom nyam magnesium uas tau los ntawm calcining magnesite, brucite thiab magnesium hydroxide muab rho tawm los ntawm seawater lossis brine ntawm li 800-1000 C. Lub teeb taws magnesia hmoov yog lub teeb daj thiab lub teeb xim av. Nws cov particle loj yog feem ntau hauv qab 100 mesh. Nws siv lead ua ceev yog 3.07-3.22g / cm3. Nws qhov lattice yog loj, nws cov kab rov tav yog loj, nws qhov kev ntxhib los mos yog nkig, nws txoj kev ntxeem tau heev, nws yooj yim rau hnov mob nrog dej Mg (OH) 2, uas sib zog thiab muaj tsevneeg muaj zog. Lub zog.
Xaiv cov calcination txoj kev tswj thiab kev tswj ntawm lub teeb kub kub yog qhov tseem ceeb txhais tau tias yuav tau txais kev ua si zoo. Nrog kev nce ntawm qhov ntsuas kub, qhov tshwj xeeb ntawm cheeb tsam ntawm MgO txo qis. Cov txheej txheem recrystallization ntawm MgO nce, cov dispersion decreases sharply thiab cov kev ua kom tsawg thaum lub kub yog siab tshaj 1000 C. Cov kev kho thiab cov khoom sib txawv ntawm tib kub yog tseem ceeb heev uas cuam tshuam rau MgO yam. Yog hais tias nyob rau hauv lub txaj uas muaj lub txaj thiab ua kom raug rho tawm hauv tsev, nws tuaj yeem ua rau lub sijhawm sai sai, thiab lub qhov muag kub ntxhov magnesia hmoov nrog qhov kev ua si ntau tshaj. Siv qhov kiln thiab pev cov kiln li cov blocks loj, lub sij hawm calcination ntev, thiab lub qhov hluav taws xob feem ntau overburned thaum lub sab hauv uas kub hnyiab, uas yuav txo qhov kev ua si ntawm lub teeb ntawm lub teeb ci nqaij hlav magnesia hmoov. Thaum kuaj calcium magnesite hauv cov zom kaws, qhov teeb meem yog nruab nrab ntawm ob qho, thiab kev ua haujlwm ntawm lub teeb ci nqaij hlav magnesia hmoov kuj tswj tau.
Qhov nyhav ntawm txhua pawg ntawm cov khoom tiav tsis yog ntau tshaj 120 t.
Cov qauv kev txiav txim me me yuav tsum raug samfwm ua ntej pawg ua ke, thiab kuaj cov tshuaj tsomxam kev tshuaj xyuas yuav tsum raug sampled tom qab pawg neeg ua haujlwm. Cov qauv tau muab hauv cov hnab me me (25kg) thiab hauv hnab loj (1000kg).
Tom qab kev sib tov tag nrho cov khoom siv me me, qhov loj me me yog txiav txim siab ntawm qhov piv txwv ntawm 10-20g. Cov kev kuaj ntawd tau txo kom tsawg txog 200 g thiab xa mus rau qhov chaw kuaj ntshav.
Yog tias cov tshuaj muaj kuab pauv tsis zoo lossis tsis txawv txav, yuav tsum kuaj ob yam khoom rov tuaj kuaj dua, thiab qhov rov kuaj dua yuav yog qhov kawg ntawm cov khoom kuaj.
