Niobium yog siv rau hauv cov hlau tsis muaj hlau. Nws txhim kho lub zog ntawm cov alloys, tshwj xeeb tshaj yog nyob rau hauv qis kub. Alloys uas muaj niobium yog siv nyob rau hauv dav hlau cav thiab foob pob ua ntxaij, kab teeb thiab girders rau lub tsev thiab roj rigs, thiab roj thiab roj pipelines.
Puas niobium puas tsim kev puas tsuaj rau tib neeg?
Niobium thiab nws cov tebchaw yuav muaj tshuaj lom (niobium plua plav ua rau qhov muag thiab tawv nqaij khaus), tab sis tsis muaj ntawv ceeb toom ntawm tib neeg raug tshuaj lom los ntawm nws Sib nrug los ntawm kev ntsuas nws cov concentration, tsis muaj Kev tshawb fawb txog niobium hauv tib neeg tau ua tiav. Niobium, thaum nqus tau, yog khaws cia hauv lub ntsws, thiab thib ob hauv cov pob txha.
Dab tsi ua rau niobium tshwj xeeb?
Niobium yog ib qho ci iab, dawb hlau uas feem ntau tsim zaj duab xis ntawm nws qhov chaw thaum raughuab cua, tig xim xiav, ntsuab, lossis daj, raws li Chemicool. Nws muaj ntau yam kev siv los ntawm kev siv hauv cov hniav nyiaj hniav kub hypoallergenic rau lub tshuab dav hlau mus rau cov hlau nplaum superconducting.
Vim li cas niobium siv hauv foob pob hluav taws?
Kev siv ntawm Niobium
Raws li C-103 alloy, nws tau siv rau lub foob pob hluav taws thiab lub qhov tso pa tawm rau lub tshuab dav hlau thiab foob pob hluav taws vim nws lub zog siab thiab oxidation tsis kam ntawm qhov qis. nyhav Tsis ntev los no, nws tau txais kev pom zoo hauv nws daim ntawv ntshiab rau cov khoom siv semiconductor thiab cov khoom tiv thaiv corrosion.
Vim li cas niobium tseem ceeb?
Niobium yog siv rau hauv tsim cov khoom kub-resistant alloys thiab tshwj xeeb stainless hlau, nrog rau lub zog siab qis alloy carbon steels. … Qhov kev thov rau niobium tau ntxiv dag zog, feem ntau yog nyob tom qab ntawm kev siv ntau ntxiv hauv kev tsim steel thiab hluav taws xob.
