Lub cev muaj zog ntawm manganese

Manganese muaj qhov ceev ntawm 7.2 grams ib cubic centimeter, uas yog siab dua li cov hlau feem ntau. Nws muaj qhov melting point ntawm 1244 degree thiab kub kub ntawm 1962 degree. Manganese yog ib qho nyuaj, nkig hlau uas nyuaj ua haujlwm nrog tes. Nws yog heev tiv taus hnav thiab tsim kua muag thiab feem ntau yog siv nyob rau hauv high-stress daim ntaub ntawv uas lub zog yog ib qho tseem ceeb.

Kev siv cov manganese

Manganese yog siv nyob rau hauv ntau yam kev siv sib txawv. Ib qho ntawm feem ntau siv rau manganese yog nyob rau hauv cov hlau alloys. Nws feem ntau ua ke nrog hlau los tsim cov hlau, thiab tseem siv rau lwm cov hlau xws li txhuas thiab tooj liab. Manganese kuj tseem siv tau los txhim kho cov khoom ntawm lwm yam hlau, xws li nce hardness ntawm txhuas.

Manganese kuj tseem siv dav hauv kev lag luam chiv, qhov twg nws yog siv los txhawb kev loj hlob ntawm cov nroj tsuag noj qab haus huv. Nws yog ib qho tseem ceeb rau ntau cov nroj tsuag thiab feem ntau ntxiv rau hauv av kom ntseeg tau tias cov qoob loo noj qab haus huv thiab ua kom muaj txiaj ntsig zoo.

Lwm qhov tseem ceeb ntawm kev siv manganese yog hauv kev tsim cov roj teeb. Manganese yog siv los ua qhov zoo electrode nyob rau hauv ntau hom roj teeb, xws li alkaline roj teeb, lithium-ion roj teeb, thiab zinc-carbon roj teeb. Nws kuj tseem siv rau hauv kev tsim cov electrodes rau vuam thiab lwm yam kev siv kub.

Cov txiaj ntsig kev noj qab haus huv ntawm manganese

Manganese yog cov khoom noj tseem ceeb rau tib neeg kev noj qab haus huv thiab xav tau rau kev ua haujlwm zoo ntawm ntau cov enzymes hauv lub cev. Nws yog ib qho tseem ceeb rau kev tswj cov pob txha noj qab haus huv, tsim cov ntaub so ntswg tshiab, thiab tswj cov piam thaj metabolism. Manganese kuj tseem ceeb rau lub hlwb noj qab haus huv thiab xav tias yuav pab tiv thaiv Alzheimer tus kab mob.

Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias ntau dhau ntawm manganese tuaj yeem ua rau tib neeg noj qab haus huv. Cov qib siab ntawm manganese tau txuas nrog cov teeb meem hauv lub paj hlwb, suav nrog cov tsos mob zoo li Parkinson. Nws yog ib qho tseem ceeb kom txwv tsis pub muaj manganese kom tsis txhob muaj cov teebmeem kev noj qab haus huv no.

Qhov chaw ntawm manganese

Manganese muaj nyob hauv ntau qhov chaw sib txawv thoob ntiaj teb. Cov neeg tsim khoom loj tshaj plaws ntawm manganese suav nrog South Africa, Australia, thiab Tuam Tshoj. Manganese deposits tuaj yeem pom hauv cov pob zeb sedimentary, pob zeb tsis muaj zog, thiab cov pob zeb metamorphic. Nws tuaj yeem pom hauv av, dej, thiab khoom noj.
