Aluminium -manganese alloysyog lub teeb yuag tsis tau muaj zog, nrog zoo heev tiv thaiv corrosion. Lawv tau siv dav hauv cov kaus poom dej haus, tsheb, thiab cov khoom siv dav hlau.
Copper -manganese alloyspaub txog lawv cov hluav taws xob zoo conductivity thiab stability, ua rau lawv haum rau cov khoom siv hluav taws xob thiab cov cuab yeej precision.
Magnesium{0}}manganese alloysyog siv nyob rau hauv aerospace thiab tiv thaiv daim ntaub ntawv uas tsis muaj yuag thiab siab zog yog qhov tseem ceeb.
Cov alloys no qhia tau hais tias manganese pab txhim kho cov khoom siv zoo li cas, ua kom cov khoom lag luam ntev thiab txo cov kev xav tau ntawm kev saib xyuas.
3. Roj teeb kev lag luam
Manganese hlau thiab nws cov tebchaw ua lub luag haujlwm tseem ceeb hauv kev khaws cia lub zog. Tshwj xeeb,manganese dioxidethiabmanganese hlauyog cov khoom tseem ceeb rau kev tsim cov roj teeb.
Alkaline thiab zinc- roj teeb carbon:Manganese dioxide ua raws li ib tug depolarizer, txhim kho efficiency thiab lifespan ntawm lub roj teeb.
Lithium{0}}Ion roj teeb:Manganese yog siv nyob rau hauv lithium manganese oxide cathodes, uas muaj zog ceev ceev, stability, thiab kev nyab xeeb piv rau lwm yam ntaub ntawv.
Tshiab zog tsheb:Raws li lub tsheb fais fab xav tau nce, manganese- cov khoom siv roj teeb raws li xav tau ntau dua rau lawv qhov sib npaug ntawm tus nqi, kev ua haujlwm, thiab kev nyab xeeb.
Yog li, manganese plays lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov thev naus laus zis huv huv thiab txhawb kev siv zog thoob ntiaj teb rau kev ruaj khov.
4. Kev lag luam tshuaj
Hauv kev lag luam tshuaj, manganese yog siv los tsim ntau yam sib txuas, suav nrog manganese sulfate, manganese chloride, thiab poov tshuaj permanganate. Cov tshuaj no muaj ntau yam kev siv:
Manganese sulfateyog siv nyob rau hauv chiv los kho manganese deficiency nyob rau hauv cov qoob loo, txhim kho cov nroj tsuag kev loj hlob thiab productivity.
Potassium permanganateyog ib tug muaj zog oxidizing neeg sawv cev siv nyob rau hauv dej purification, tshuaj tua kab mob, thiab kev kho dej khib nyiab.
Manganese compoundskuj tseem siv tau hauv ceramics, iav xim, thiab textile dyeing.
Vim hais tias manganese tebchaw tuaj yeem faib cov xim liab, ntshav, lossis xim av rau iav thiab ceramics, lawv kuj tseem muaj txiaj ntsig hauv kev siv kho kom zoo nkauj thiab kos duab.
5. Electronics thiab lwm yam kev siv
Manganese hlau yog siv rau hauv cov khoom siv hluav taws xob vim nws cov khoom sib nqus thiab hluav taws xob. Nws yog siv nyob rau hauv kev tsim khoomferrites, semiconductors, thiabresistors. Manganese ferrite, piv txwv li, yog cov khoom siv hlau nplaum siv hauv inductors thiab transformers.
Tsis tas li ntawd, manganese yog siv raws li ib tughardening tus neeg sawv cevnyob rau hauv npib thiab raws li ib tug additive nyob rau hauv vuam cov ntaub ntawv los txhim kho kev ua tau zoo. Manganese phosphates yog siv los ua coatings los txhim kho kev hnav thiab corrosion tsis kam ntawm hlau nto.
6. Qhov tseem ceeb hauv kev lag luam niaj hnub
Lub ntiaj teb tseem ceeb ntawm manganese hlau txuas ntxiv mus ntxiv vim muaj kev nthuav dav, kev tsim kho vaj tse, thiab hloov mus rau lub zog tauj dua tshiab. Lub teb chaws tsim cov hlau thiab roj teeb ntau, xws li Tuam Tshoj, Is Nrias teb, thiab Kaus Lim Qab Teb, yog cov neeg siv khoom loj tshaj plaws ntawm manganese.
Raws li kev lag luam nrhiav kev ua tau zoo dua thiab kev tsim khoom huv si, qhov kev thov rau siab -purity electrolytic manganese hlau (EMM) tau nce siab heev. EMM yog qhov tseem ceeb rau kev tsim cov hlau tsis muaj steel, cov khoom siv tshwj xeeb, thiab cov roj teeb siab heev uas siv hauv tsheb fais fab thiab khoom siv hluav taws xob.
