Niobium Tube

Niobium yog qhov kub thiab txias tiv taus grey dawb hlau nrog lub melting point ntawm 2468 degree, lub boiling point ntawm 4742 degree, thiab ib tug ceev ntawm 8.57g / cm³. Niobium muaj ductility zoo, tab sis nws cov ductility txo nrog nce impurity cov ntsiab lus thiab ua nyuaj. Niobium raj tuaj yeem muab faib ua cov raj niobium ntshiab thiab niobium alloy raj raws li lawv muaj pes tsawg leeg. Cov qib siab ntawm cov niobium cov raj ntshiab yog RO4200 (purity Ntau dua lossis sib npaug li 99.95%) thiab RO4210 (purity 99.99%). Nyob rau hauv cov nqe lus ntawm specifications, niobium raj muaj ntau yam diameters, los ntawm Φ Ntau tshaj los yog sib npaug li 1 hli mus rau qhov ntau thiab tsawg. Nyob rau tib lub sijhawm, muaj cov qauv nruj rau sab nraud txoj kab uas hla thiab phab ntsa thickness kam rau ua ntawm niobium raj kom paub meej cov khoom zoo thiab raug.

Niobium tubes tuaj yeem tswj tau lub zog txaus thiab cov yas ntawm qhov kub thiab txias, ua rau lawv yog cov khoom siv zoo tshaj plaws rau kev tsim khoom xws li cov cua kub cua kub cua sov, cov pwm kub kub, cov khoom kub kub, thiab cov khoom kub kub. Niobium tubes muaj corrosion kuj zoo rau ntau yam kua qaub, alkali, thiab ntsev tov, tshwj xeeb tshaj yog nyob rau hauv tej yam kev mob ntawm tsis kam mus nitric acid, hydrochloric acid, los yog sulfuric acid corrosion. Niobium muaj qhov zoo ntawm qhov kub thiab txias thiab kev ua haujlwm txias ntawm qhov kub thiab txias, thiab tuaj yeem txias txias rau hauv ntau hom khoom xws li daim hlau, rods, thiab cov xov hlau. Qhov zoo tshaj plaws superconductivity yog ua tiav ntawm ib ncig ntawm qhov rho tawm 260 degree, qhov chaw tiv thaiv zero, ua rau nws yog ib qho tseem ceeb hauv kev tsim cov khoom siv superconducting.

Raws li cov khoom tshwj xeeb ntawm lub cev thiab tshuaj lom neeg uas tau hais los saum no, niobium hlab ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam. Hauv cov roj av refining thiab cov txheej txheem tshuaj, cov kav dej niobium feem ntau yog siv los ua cov kav dej kub hauv qhov kub thiab siab, nrog rau qee lub sijhawm uas yuav tsum muaj kev tiv thaiv corrosion. Nws tuaj yeem tiv taus qhov yaig ntawm corrosive media xws li kua qaub, alkali, ntsev, thiab lwm yam, ua kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov txheej txheem. Lub caij no, cov raj niobium kuj tau siv los ua cov raj tiv thaiv rau cov ntsuas kub thiab ntsuas qib kom tiv thaiv corrosion lossis kub kub puas tsuaj rau cov cuab yeej ntsuas. Hauv nuclear reactors, niobium raj feem ntau yog siv los ua nuclear roj cladding hlab vim lawv cov hluav taws xob zoo heev thiab corrosion kuj. Hom raj no yuav tsum tau muaj kev cuam tshuam rau lub sijhawm ntev ntawm cov khoom siv hluav taws xob, thaum cov raj niobium tuaj yeem tswj tau qhov ruaj khov ntawm lawv cov qauv thiab kev ua haujlwm. Niobium raj kuj tseem siv tau los ua cov kav dej txias rau cov tshuab hluav taws xob nuclear, hloov cov cua sov loj uas tsim los ntawm lub tshuab hluav taws xob thiab ua kom nws txoj haujlwm nyab xeeb.

Hauv kev lag luam metallurgical, niobium raj tuaj yeem siv los ua cov khoom cua sov thiab cov ntaub ntawv rwb thaiv tsev rau cov cua kub kub kom tiv taus qhov chaw ua haujlwm ntawm qhov kub thiab txias. Hauv kev lag luam iav, niobium raj tuaj yeem siv los tsim cov khoom kub-kub resistant iav kiln, kom ntseeg tau cov khoom siv iav zoo. Niobium compounds thiab alloys muaj cov ntawv thov tseem ceeb hauv kev lag luam hluav taws xob. Piv txwv li, niobium oxides tuaj yeem siv los tsim cov khoom siv hluav taws xob superconducting uas ua rau xoom tsis kam ntawm qhov kub thiab txias, uas yog qhov tseem ceeb rau kev txhim kho lub zog ntawm cov khoom siv hluav taws xob. Niobium tubes tseem tuaj yeem siv los ua cov khoom siv nqus rau lub tshuab nqus tsev kom tshem tawm cov roj seem hauv lub tshuab nqus tsev, txhim kho lub tshuab nqus tsev kawm ntawv, thiab xyuas kom muaj kev ruaj ntseg thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob.

Niobium raj kuj tseem siv tau rau ntau qhov chaw xws li cov khoom siv kho mob, kev tsim nkoj, kev sib hloov hluav taws xob, cov khoom siv tshuaj, thiab lwm yam, kom ua tau raws li ntau yam kev ua haujlwm ib puag ncig nrog lawv cov kev ua haujlwm tshwj xeeb. Hauv cov ntsiab lus, niobium raj muaj ntau yam kev siv, npog ntau yam xws li petrochemicals, aerospace, nuclear kev lag luam, thiab kev lag luam hluav taws xob.
