1. Nyiaj: Ntawm Npib, Kub thiab Nyiaj thiab Ultrafine Niobium niobium nanopowder qee zaum siv ua ke raws li cov khoom siv uas muaj nqi nyob hauv cov nyiaj npib
2. Super Alloys: ib feem loj ntawm Niobium rau cov ntawv ntshiab hlau lossis Niobium hlau-Niobium hlau-Niobium hlau, siv rau hauv kev tsim cov npib tsib xee, siv cov roj ntsha chromium thiab hlau-luj super alloys ntiaj teb. Cov alloys tuaj yeem siv tau rau hauv cov hluav taws xob tawm, roj tshuab hluav taws xob, cov khoom siv rocket, turbochargers thiab kub ntawm cov khoom sib txuas;
3. Hlau Daim Ntawv Thov: Hauv ntau cov ntsiab lus microOYOYO, NIobium lub luag haujlwm yog qhov zoo tshaj plaws hauv niobium atom, peb tuaj yeem ua tau kev ua haujlwm txhim kho steel lub hom phiaj. Ua tau steel ntxiv 0.001% -0.1% niobium, yog txaus los hloov cov khoom siv me me ntawm cov hlau;

Muab tso rau hauv cov thawv kaw ntom ntom thiab khaws cia rau hauv qhov chaw txias, qhuav.
1. Thawv: Siv airtight ntim ua los ntawm cov ntaub ntawv uas tau tshaj cov hlau, xws li iav lossis qee qhov plastics. Zam txhob siv cov thawv uas yuav cuam tshuam nrog cov hmoov.
2. Ib puag ncig: khaws cov thawv ntim rau hauv qhov chaw txias thiab qhuav kom tiv thaiv kev nqus dej noo, uas yuav ua rau oxidation lossis lwm yam kev tawm tsam.
3. Qhov kub: Khaws thaj chaw cia rau ntawm qhov kub khov thiab tsis txhob sov lossis txias.
4. Sau npe: Sau npe kom meej rau cov thawv ntim nrog cov ntsiab lus thiab cov ntaub ntawv kev nyab xeeb.

6. Zam kom muaj kev paug: ua kom cov chaw cia kom huv thiab tsis muaj kuab thiab tsis muaj kuab lom uas tuaj yeem sib xyaw nrog cov hmoov.
Nws yog ruaj khov nyob rau hauv chav nyob hauv huab cua, thiab pib oxidize ntawm 200 ° C los ua yeeb yaj kiab oxide.
Zam kev oxides, alkalis, thiab halogens. Niobium muaj cov xeb uas muaj zog ua rau cov kua qaub.
Niobium hmoov feem ntau suav tias muaj kev lom zem tsawg thiab tsis suav tias yog kev phom sij rau tib neeg nyob rau hauv cov kev coj ua ib txwm muaj. Txawm li cas los xij, zoo li ntau cov hmoov hlau hlau, nws yuav ua rau muaj kev phom sij txog kev noj qab haus huv yog tias ua tsis tau kev nyab xeeb rau kev nyab xeeb. Nov yog qee yam kev ceev faj:
1. Inhalation: nqus tau ntawm cov hmoov nplej hlau tej zaum yuav ua pa pheeb suab lossis lwm yam mob ntsws. Kev tiv thaiv uas tsim nyog ua pa tau pom zoo thaum daws cov hmoov loj ntawm niobium hmoov lossis hauv plua plav ib puag ncig.
2. Cov tawv nqaij tiv thaiv: Txawm hais tias Niobium tsis ua rau cov tawv nqaij hnyav, nws tseem yog kev xyaum ua kom tau looj hnab looj tes kom tiv thaiv kom tsis txhob muaj hnab looj tes kom tiv thaiv kom tsis txhob muaj hnab looj tes kom tiv thaiv kom tsis txhob muaj hnab looj tes kom tiv thaiv kom tsis txhob muaj hnab looj tes kom tiv thaiv ib lub peev xwm ntawm cov tawv nqaij uas muaj peev xwm tiv thaiv cov tawv nqaij.
3. Kev noj: Cov hmoov hlau tsis nyab xeeb, yog li nws yog ib qho tseem ceeb kom muaj kev nyiam huv zoo kom tsis txhob noj.
4. Kev ua xua: txawm tias tsis tshua muaj, qee tus neeg yuav tau ua tsis haum rau qee cov hlau, suav nrog Niobium.
Thaum thauj Niobium hmoov, nws yog ib qho tseem ceeb kom ua kev tiv thaiv tshwj xeeb kom muaj kev nyab xeeb thiab ua raws li kev cai. Nov yog qee qhov kev txiav txim siab tseem ceeb los coj mus rau hauv tus account:
1. Ntim: Siv cov ntaub ntawv ntim uas tsim nyog uas muaj zog thiab ua pov thawj. Lub thawv yuav tsum tau muab ntim thiab ua los ntawm cov ntaub ntawv uas tsis suav nrog niobium.
2. Daim ntawv lo: Daim ntawv lo qhia meej rau cov ntsiab lus ntawm pob, suav nrog cov khoom siv tshuaj lom neeg (Niobium hmoov) thiab cov ntaub ntawv kev phom sij. Suav cov lus qhia thiab cov ntaub ntawv tiv toj thaum muaj xwm txheej ceev.
3. Kev tswj hwm ua raws: Tshawb xyuas thiab ua raws li cov kev cai hauv zos, cov kev pab thoob ntiaj teb txog kev thauj mus los ntawm cov hmoov hlau. Qhov no yuav suav nrog cov kev cai tshwj xeeb rau cov khoom siv phom sij.
4. Nyhav txwv: Ua tib zoo saib rau qhov poob qis ntawm lub thawv kom ntseeg tau tias chaw thau khoom nyab xeeb, thauj khoom thiab tsheb thauj mus los.
5 Cov ntaub ntawv tsis huv yuav ua rau muaj kev pheej hmoo thaum thauj mus los.
6. Kev tswj kub: yog tias tsim nyog, kev tswj hwm cov ntsuas kub kom tiv thaiv ib qho kev tsis zoo thaum lub sijhawm thauj mus los.
7. Cov ntaub ntawv: Npaj tag nrho cov ntaub ntawv thauj khoom tsim nyog, suav nrog cov ntawv txheeb xyuas kev nyab xeeb (SDS) thiab ib qho uas yuav tsum muaj lossis tshaj tawm.
8. Kev ceev faj kev ceev faj: Tus kws qhia qhia kev koom tes nrog kev thauj mus los thiab kev ntsuas kev nyab xeeb rau Niobium hmoov.
