Niobium Rod

Shaanxi Zhongheng Weichuang Hlau Khoom Co., Ltd. muab ntau qhov zoo ntawm niobium rods nrog purity txog li 99.95%, thiab cov lus qhia tshwj xeeb tuaj yeem ua raws li qhov xav tau. Niobium yog cov hlau refractory nrog lub melting point ntawm 2468 degree C, ntau dua li melting point ntawm platinum (1772 degree C). Cov hlau refractory paub txog lawv qhov siab melting point, tsawg vapor siab, siab elastic modulus, siab thermal stability, thiab tsawg coefficient ntawm thermal expansion. Ntawm cov hlau refractory no, niobium muaj qhov ntom ntom ntawm 8.6g / cm³, uas ua rau nws muaj txiaj ntsig tshwj xeeb hauv qee yam kev siv tshwj xeeb.

Niobium rods tsis tsuas yog tau txais txiaj ntsig zoo ntawm cov ntsiab lus siab melting ntawm niobium hlau, tab sis kuj tseem muaj cov khoom siv zoo heev thiab qhov smoothness vim lawv cov forging thiab polishing kev kho mob. Cov yam ntxwv no ua rau cov niobium rods tswj kev ua haujlwm ruaj khov txawm tias nyob hauv ib puag ncig huab, yog li ua tau raws li ntau yam kev xav tau kev lag luam thiab muaj ntau yam kev siv hauv ntau qhov chaw lag luam.

Hauv cov tshuab dav hlau, niobium rods feem ntau yog siv los ua cov khoom tsim khoom rau cov khoom kub xws li turbine blades, combustion chamber Cheebtsam, thiab lwm yam. Nws lub siab melting point, siab zog, thiab zoo creep kuj pab kom niobium rods kom ruaj khov qauv thiab kev ua tau zoo nyob rau hauv. huab cua kub ib puag ncig. Hauv tshuab foob pob hluav taws, niobium rods kuj tseem siv los tsim cov nozzles thiab lwm yam khoom siv kub ntawm lub foob pob hluav taws, kom ntseeg tau tias foob pob hluav taws tuaj yeem tiv taus qhov kub thiab txias ntsuas thaum lub sij hawm siab ceev thiab tso tawm.

Hauv nuclear reactors, niobium rods yog dav siv nyob rau hauv kev tsim cov roj yam cladding, tswj rods, thiab lwm yam tseem ceeb Cheebtsam vim lawv tsawg neutron absorption hla seem thiab zoo heev corrosion kuj. Cov khoom siv no yuav tsum tau ua haujlwm ntev hauv ib puag ncig uas muaj hluav taws xob muaj zog thiab kub thiab siab, thiab niobium rods ua tau raws li cov cai no. Niobium rods feem ntau yog siv hauv kev lag luam tshuaj los tsim cov khoom siv tiv thaiv corrosion thiab cov khoom siv, tshwj xeeb tshaj yog thaum cuam tshuam nrog cov xov xwm corrosive xws li muaj zog acids thiab alkalis. Nws cov tshuaj lom neeg ruaj khov zoo ua rau cov niobium rods tswj kev ua haujlwm ruaj khov mus ntev hauv cov cheeb tsam hnyav no.

Hauv kev lag luam hluav taws xob, niobium rods yog siv los tsim ntau yam khoom siv hluav taws xob thiab khoom siv, xws li capacitors, resistors, thermistors, thiab lwm yam. Cov khoom siv hluav taws xob siab thiab zoo thermal stability ntawm niobium ua rau nws yog cov khoom siv zoo tagnrho rau cov khoom siv no. Niobium rods kuj tseem siv los tsim cov khoom xws li cathodes thiab anodes hauv lub tshuab nqus tsev hluav taws xob, uas yuav tsum tau ua haujlwm hauv lub tshuab nqus tsev thiab qhov kub thiab txias, thiab niobium rods tuaj yeem ua tau raws li cov kev cai no.

Muaj qhov sib txawv tseem ceeb ntawm niobium rods thiab tantalum rods nyob rau hauv cov nqe lus ntawm lub cev khoom, tshuaj lom neeg, thaj chaw siv, thiab cov nqi. TANTATUM muaj qhov siab ntom ntom, uas muab nws qhov zoo dua nyob rau qee qhov xwm txheej uas yuav tsum muaj cov khoom siv ntom ntom ntom. Txawm hais tias niobium muaj qhov ceev dua, nws qis dua me ntsis piv rau tantalum. Nyob rau hauv chav tsev kub, tantalum feem ntau pom zoo toughness, thaum niobium kuj muaj zoo toughness. Txawm li cas los xij, thaum nws los txog rau qhov kev hloov pauv kub, ob qho tib si yuav txawv, tab sis cov txiaj ntsig tshwj xeeb yuav txawv ntawm cov khoom xws li cov khoom siv purity thiab kev ua haujlwm.

Feem ntau hais lus, vim qhov tsis tshua muaj thiab kev ua tau zoo ntawm tantalum, tus nqi ntawm tantalum rods yog qhov siab. Txawm hais tias niobium tseem yog cov hlau tsis tshua muaj, nws tus nqi kuj pheej yig, uas ua rau cov niobium rods muaj kev sib tw ntau dua hauv qee qhov kev siv nqi. Hauv cov ntsiab lus, thaum xaiv cov khoom siv twg, nws yog qhov yuav tsum tau xav txog cov xwm txheej tshwj xeeb ntawm daim ntawv thov thiab cov kev xav tau dav dav.
