Yog tias koj yuav ua qhov tsim cov qauv pyrotechnic ib qho ntawm koj txoj haujlwm nyiam, ces thawj qhov koj ntsib yog qhov teeb meem ntawm kev nrhiav cov khoom tsim nyog rau koj txoj haujlwm. Thiab cov lus nug tseem ceeb tshaj plaws yog qhov twg kom tau txais magnesium? Peb yuav muab cov lus teb ntxaws ntxaws rau nws, raws li txoj kev, tau txheeb xyuas txhua qhov tshwj xeeb ntawm lub caij no.
YIb qho tseem ceeb ntawm magnesium
Ua ntej, cia peb paub nws. Magnesium yog ib qho ntawm cov ntsiab lus tseem ceeb ntawm lub sijhawm teem sijhawm. Nws occupies 2% ntawm cov muaj pes tsawg leeg ntawm lub ntiaj teb crust - qhov no yog lub xya qhov chaw ntawm lwm yam. Nws cov ntsev tuaj yeem pom nyob rau hauv dej hiav txwv, cov pob zeb ntawm cov pas dej nws tus kheej.
Ntau tshaj 200 lub ntuj sib txuas uas muaj magnesium kuj paub. Txawm li cas los xij, hauv kev lag luam, dolomite, magnesite thiab carnallite feem ntau yog siv los ua raw khoom. Lawv cov deposits tau tsim los ntawm sedimentary txoj kev nyob rau hauv lub Precambrian lub sij hawm. Cov nyiaj tso nyiaj loj tshaj plaws nyob rau thaj chaw ntawm Lavxias Federation, Tebchaws Asmeskas, Tuam Tshoj.
Nov yog lub teeb dawb-nyiaj hlau. Nws yog tus cwj pwm los ntawm qhov ci ntsa iab ntawm cov xim dawb nrog kev tso tawm ntau lub zog thermal.
Yuav ua li cas txiav txim siab magnesium?
Thaum txheeb xyuas qhov twg kom tau txais magnesium, nws yog ib qho tseem ceeb kom paub nws qhov txawvnta, kom tsis txhob cuam tshuam cov hlau no nrog lwm yam.
Cov yam ntxwv tseem ceeb muaj raws li hauv qab no:
- Lub teeb yuag. Magnesium yog sib dua, piv txwv li, txhuas ob zaug. Yog li yog tias koj tab tom saib ib feem uas tsis muaj qhov hnyav rau nws qhov loj me, nws yuav yog magnesium.
- Kev sib cuam tshuam nrog cov kua qaub. Thaum koj pom qhov chaw kom tau txais magnesium, nco ntsoov nqa 9 feem pua ntawm vinegar thiab ntawv xuab zeb nrog koj. Ntxuav qhov chaw ntawm qhov pom nrog "sandpaper" thiab tso me ntsis ntawm vinegar rau nws. Magnesium yuav nthuav tawm nws tus kheej los ntawm kev tso tawm hydrogen.
- YCombustion. Ua ntaub ntawv me ntsis shavings los ntawm qhov pom nrog ib cov ntaub ntawv, ces muab tso rau ntawm hluav taws. Yog hais tias sawdust hlawv sai sai, tawm hauv qab ib tug yam ntxwv dawb precipitate, ces koj twv yuav raug hu nrhiav tau dab tsi koj tab tom nrhiav.
Daim ntawv thov
Magnesium hmoov feem ntau yog siv hauv tub rog thiab kev lag luam pyrotechnic. Nws yog ib qho tsim nyog los tsim cov flammable qhuav sib tov. Vim yog cov nplaim dawb ci ntsa iab, nws yog qhov tseem ceeb rau cov teeb pom kev zoo ntawm cov foob pob hluav taws, cov foob pob hluav taws dawb.
Siv dav hauv kev sim tshuaj lom neeg, vim nws yog ib qho kev txo qis hauv cov tshuaj organic thiab inorganic. Nws kuj tseem siv rau hauv kev tsim cov hydrogen hauv chav kuaj.
khoom lag luam
Cov neeg uas tab tom nrhiav rau qhov twg kom tau txais magnesium hlau yuav txaus siab paub tias cov ntaub ntawv twg yog muab los ntawm cov tuam ntxhab. Yeej, nws yog chips lossis hmoov. Ua raws li GOST6001-79 Ib. Raws li tus qauv, cov ntsiab lus magnesium hauv txhua daim ntawv yuav tsum tsis pub tsawg dua 99%. Qhov feem ntawm cov dej nqus dej hauv qhov no tsis ntau tshaj 0.01%.
Muaj plaub lub npe tseem ceeb: MPF-1, MPF-2, MPF-3, MPF-4. Lawv qhov sib txawv tsuas yog qhov loj ntawm magnesium granules.
Vim tias cov hmoov yog cov tshuaj reactive heev, nws tuaj nyob rau hauv airtight tin ntim. Qhov no yog qhov yuav tsum tau ua ua ntej rau kev khaws cia, vim tias nws cov kev cuam tshuam nrog oxygen tuaj yeem ua rau muaj kev sib txuas ntawm tus kheej.
Yuav cov hmoov los yog chips
Txoj kev yooj yim tshaj plaws rau "nyiaj txiag" yog mus yuav lossis xaj khoom. Qhov twg thiaj li tau txais magnesium hmoov? Koj tuaj yeem nrhiav tau ib lub khw hauv koj lub nroog lossis xaj xa cov hmoov los yog shavings los ntawm kev xa ntawv tuaj rau koj lub tsev.
Hnub no, magnesium tau muag tsis yog hauv cov thawv ntim khoom loj xwb. Koj tuaj yeem xaj nws yooj yim hauv ib lub thawv ntawm txhua lub ntim uas haum rau koj. Yog li, piv txwv li, 1 kg ntawm magnesium hmoov yuav raug nqi rau koj, qhov nruab nrab, 300 rubles.
Kev yuav khoom tuaj yeem ua hauv khw hauv online "Alibaba", "Ruskhim", "Lavxias Hlau", "BVB Alliance", Shilanet thiab lwm yam.
Kuv tuaj yeem tau magnesium hauv tsev nyob qhov twg?
Nws tsis tas yuav siv nyiaj rau kev yuav khoom rau koj qhov kev sim. Tshawb xyuas koj lub tsev, vaj, vaj, tsev qiv ntawv, lossis khaws cov cuab yeej qub. Nyob ntawd koj tuaj yeem nrhiav "cov ntaub ntawv raw" dawb. Peb yuav qhia koj qhov twg kom tau txais magnesium tej zaum:
- Snail qubchainsaw "Kev phooj ywg" - lub ntsiab yog 80% magnesium alloy.
- Lub cav ntawm lub tsheb "Zaporozhets". Cov muaj pes tsawg leeg ntawm nws lub hau npog thiab lub tog raj kheej thaiv yog magnesium alloy.
- Magnesium anodes rau boiler. Yog tias koj nrhiav tsis tau hauv tsev, nws yooj yim mus yuav cov khoom ntawm cov khoom siv kho vajtse thiab cov khoom siv hauv tsev.
- Hlau xaum sharpeners. Yog tias koj tsis muaj cov khoom siv ntawm koj tus kheej, koj tuaj yeem yuav lawv rau tus nqi me me ntawm cov ntawv sau.
- Txhua qhov chaw bearing the inscription MG-90.
Koj tuaj yeem mus rau qhov chaw khaws khoom seem. Nrhiav kom paub txog qhov muaj magnesium thiab, tsuas yog nyob rau hauv cov ntaub ntawv, txhuas - assemblers feem ntau confuse ob.
Industrial mining
Txoj hauv kev tseem ceeb kom tau txais magnesium hauv kev tsim khoom yog electrolytic smelting ntawm anhydrous magnesium chloride hauv da dej electrolysis. Qhov no yog li cas nws cov ntsev tau muab faib ua chloride thiab hlau ions. Ib ntus, cov magnesium ntshiab tau nce los ntawm da dej thiab cov khoom siv tshiab tau pib hloov.
Txoj kev no yog tus cwj pwm los ntawm qhov muaj impurities, yog li magnesium mus los ntawm kev ua kom huv ntxiv. Qhov no yog electrolytic refining nyob rau hauv lub tshuab nqus tsev tej yam kev mob nrog tshwj xeeb additives - fluxes. Cov tom kawg nyiam impurities, ua rau yuav luag ntshiab magnesium (cov ntsiab lus ntawm impurities tsis ntau tshaj 0.0001%).
Cov txheej txheem thermal kuj tseem cuam tshuam. Qhov ntsuas kub siab yog tsim nyob rau hauv uas cov tshuaj tiv thaiv ntawm magnesium oxide nrog silicon los yog coke pib. Yog li ntawd, magnesium purified heev yog tsim los ntawm dolomite (feedstock) tsis mus txog rau theem.sib cais rau hauv ntsev (calcium thiab magnesium) thiab purification. Nrog rau txoj kev no, dej hiav txwv kuj tuaj yeem dhau los ua qhov chaw ntawm cov hlau rho tawm.
Tam sim no peb paub qhov twg kom tau txais magnesium hauv kev lag luam thiab hauv tsev. Koj tuaj yeem yuav lossis xaj khoom DIY.
