99,95% Chiyero cha Niobium chubu chopukutidwa ndi chitoliro cha Niobium
Niobium chubu ndi chubu chachitsulo chogwira ntchito kwambiri, chopangidwa makamaka ndi niobium (Nb), chinthu chosinthira chitsulo chokhala ndi malo osungunuka kwambiri (2468 ° C) ndi malo otentha (4742 ° C), komanso kachulukidwe ka 8.57g/cm ³. Machubu a Niobium amakhala ndi chiyero chambiri, monga ≥ 99.95% kapena 99.99%, ndipo amatsatira miyezo ya ASTM B394. Atha kuperekedwa m'malo ovuta, olimba, kapena ofewa, okhala ndi kukana kwa dzimbiri komanso kukana kutentha kwambiri, ndipo amagwiritsidwa ntchito kwambiri muzamlengalenga, zamagetsi, ndi mafakitale a petrochemical.

1. Fakitale yathu ili mumzinda wa Luoyang, m'chigawo cha Henan. Luoyang ndi malo opangira migodi ya tungsten ndi molybdenum, kotero tili ndi zabwino zonse mumtundu ndi mtengo;
2. Kampani yathu ili ndi anthu ogwira ntchito zaluso omwe ali ndi zaka zopitilira 15, ndipo timapereka mayankho ndi malingaliro omwe amafunikira kwa kasitomala aliyense.
3. Zogulitsa zathu zonse zimawunikiridwa mosamalitsa musanatumizidwe kunja.
4. Ngati mulandira katundu wolakwika, mungathe kulankhulana nafe kuti mubwezedwe.
1.Kusankha Kwazinthu Zopangira
(Njirayi imayamba ndi kusankha kwachitsulo cha niobium choyera kwambiri)
2.Kusungunula ndi Kuponya
(Chitsulo cha niobium chosankhidwa chimasungunuka m'malo opanda mpweya kapena mpweya wa mpweya)
3.Kupanga
(Ingot ya niobium imasinthidwa kudzera munjira zosiyanasiyana zopangira monga kutulutsa kapena kutulutsa kozungulira kuti apange mawonekedwe a chubu)
4.Kutentha Chithandizo
5.Chithandizo cha Pamwamba
(zitha kuchitidwa kuchotsa zonyansa zilizonse kapena ma oxides pamwamba pa chubu)
6.Kuwongolera Kwabwino
7.Kuyanika komaliza ndi Kuyesa
8.Kupaka ndi Kutumiza
- Superconducting applications: Niobium imagwiritsidwa ntchito kwambiri popanga zida za superconducting, makamaka niobium-titanium (Nb-Ti) ndi niobium-tin (Nb3Sn) mawaya apamwamba kwambiri ndi zingwe. Zidazi zimagwiritsidwa ntchito ngati makina a maginito a resonance imaging (MRI), ma particle accelerators ndi maginito levitation (maglev) sitima.
- Azamlengalenga: Machubu a Niobium amagwiritsidwa ntchito m'makampani opanga ndege kuti agwiritse ntchito monga injini za ndege, zida za turbine za gasi, ndi makina oyendetsa ma rocket chifukwa cha mphamvu zawo zotentha kwambiri komanso kukana dzimbiri m'malo ovuta.
- Kukonza Chemical: Machubu a Niobium amagwiritsidwa ntchito m'makampani opanga mankhwala kuti apange zida zolimbana ndi dzimbiri, monga zosinthira kutentha, zotengera zotengera ndi mapaipi omwe amanyamula mankhwala owononga komanso kutentha kwambiri.
Niobium yowonjezeredwa ku chitsulo imayenga modabwitsa mawonekedwe opangidwa ndi austenite achitsulo. Mulingo wokwanira komanso wocheperako wa niobium wofunikira pakuwongolera kuwongolera kwa austenite - tirigu muzitsulo ndi 0.03 mpaka 004%. 2. Ndi kuwonjezera kwa niobium, kutentha kwamphamvu kwambewu za austenite kudzawuka.
Niobium ndi imodzi mwazitsulo zosakanizika zisanu; izi zikutanthauza kuti imagonjetsedwa kwambiri ndi kutentha kwakukulu ndi kuvala. Malo ake osungunuka a 4491 ° F (2477 ° C) amapangitsa chitsulo ichi ndi ma alloys ake kukhala abwino kwambiri pazovuta kwambiri komanso kutentha kwambiri.
Niobium samachita ndi madzi nthawi zonse. Pamwamba pa zitsulo za niobium zimatetezedwa ndi wosanjikiza woonda wa oxide.
