Niobium Foil thiab Sawb Description
Niobium yog ib qho ci ntsa iab hlau uas siv lub ntsej muag xiav thaum raug huab cua ntawm chav tsev kub. Kwv yees li cuaj caum feem pua ntawm Niobium yog siv nyob rau hauv kev tsim cov qib high-qib qauv steel, ib tug zoo deal nyob rau hauv daim ntawv ntawm niobium ntawv, ua raws li nws siv nyob rau hauv superalloys rau xws li cov ntaub ntawv xws li dav hlau cav Cheebtsam, roj turbines, foob pob ua ntxaij subassemblies, turbocharger systems. , thiab cov khoom siv hluav taws xob tiv thaiv tshav kub thiab combustion.
Niobium ntawv ci thiab sawb yog qhov ruaj khov heev kom nws tuaj yeem hloov cov hlau tsis huv hauv inorganic acid ntau lawm, tshuab lub neej tuaj yeem txhim kho ntau ntau zaus nrog nws. Lwm daim ntawv thov suav nrog nws siv hauv tshuaj, vuam, nuclear industries, electronics, optics, numismatics thiab hniav nyiaj hniav kub. Niobium qhov tsis muaj tshuaj lom thiab muaj peev xwm ua kom muaj xim los ntawm anodization yog qhov zoo. Peb cov ntawv zoo niobium tau dav siv los tiv thaiv corrosion, capacitors, optical target material, superconductors, kho mob, tub yees, thiab lwm yam.
SSC yog lub chaw muag khoom thoob ntiaj teb ntawm cov khoom zoo niobium thiab sawb uas muaj ntau tshaj li ob xyoo lawm ntawm kev paub hauv kev tsim thiab muag cov khoom niobium.
Peb muab niobium dov khoom nrog thickness 0.01mm mus rau 10mm, nrog rau niobium ntawv ci, sawb, ntawv, phaj, board thiab ribbon.
