Kev siv tswv yim rau tungsten hlau

Ntxiv nrog rau qhov tseem ceeb rau kev tsim cov coiled teeb filaments rau cov khoom siv teeb pom kev zoo, tungsten hlau yog qhov tseem ceeb rau lwm yam khoom uas nws cov khoom kub kub muaj txiaj ntsig. Piv txwv li, vim hais tias tungsten nthuav dav ntawm yuav luag tib tus nqi raws li cov iav borosilicate, cov hlau tuab tuab yog ncaj, qhov chaw tiav, thiab txiav rau hauv cov pas nrig uas yog siv rau cov iav-rau-hlau foob cov khoom hauv cov teeb pom kev zoo thiab hluav taws xob kev lag luam.
Tungsten hlau yog dav siv nyob rau hauv cov khoom siv kho mob daim ntawv thov uas siv hluav taws xob tam sim no thiab qhov twg precision yog qhov tseem ceeb. Piv txwv li, tungsten hlau yog siv los ua kev sojntsuam rau cov txheej txheem kev kho mob ntawm electrocautery, qhov twg hlau sojntsuam yog rhuab los ntawm hluav taws xob tam sim no mus rau ib tug dull liab glow thiab siv rau lub hom phiaj cov ntaub so ntswg txiav thiab cauterize - yeej, tshem tawm ib tug undesirable kev loj hlob thiab txo cov ntshav. Cov tungsten xaim tuaj yeem siv rau hauv daim ntawv ntawm ib qho ncaj, tapered, khoom sojntsuam lossis hauv qhov ntev uas tuaj yeem nkhaus rau hauv lub voj uas ua raws li cov cuab yeej txiav. Nrog nws lub siab melting point, tungsten tuav nws cov duab thiab tsis flex los yog deform ntawm qhov kub thiab txias yuav tsum tau txiav thiab cauterize cov ntaub so ntswg.

Txawm hais tias tsis yog cov khoom siv tshwj xeeb, tungsten hlau 1s muaj txiaj ntsig zoo rau lub hom phiaj ntawm lub hlwb stimulation thiab neural probing, qhov twg txoj kab uas hla ntawm cov hlau yuav tsum yog incredibly me me thiab nqaim. Ntawm ib txoj kab uas hla me me thiab ntev ntev, tungsten hlau tuav nws txoj kev ncaj thiab cov duab - cov yam ntxwv uas tseem ceeb rau kev coj ncaj ncees - deb tshaj li lwm yam hlau. Tsis tas li ntawd, tungsten hlau qhov siab tensile qhov tseem ceeb muab cov txiaj ntsig zoo rau cov hlau tshwj xeeb rau steerable qhia xov hlau hauv cov txheej txheem kho mob tsawg heev Nws qhov siab ceev kuj ua rau tungsten xaim heev radiopaque tso cai rau nws ua tau zoo nyob rau hauv daim ntawv thov fluoroscopic.
Rau siv nyob rau hauv industrial furnaces, tungsten hlau tuav nws cov duab ntawm qhov kub siab tshaj plaws, ua rau nws zoo heev rau kev txhawb nqa cov qauv, qhov cub mats, thiab lwm yam hnyav-cov kabmob qhov chaw uas yuav tsum tau tswj txoj hauj lwm ntawm cov khoom raug rau lub cub tawg kub. Tungsten hlau qhov kub tsis kam ua kom nws tuav cov khoom nyob rau hauv qhov chaw zoo nyob rau hauv qhov chaw kub yam tsis muaj sagging, collapsing, ntog, los yog lwm yam txav cov khoom tawm ntawm qhov chaw zoo.

Txhawm rau ua cov khoom siv nkaus xwb uas tsim nyog rau qhov kub siab heev uas yuav tsum tau tig cov ntshiab silicon mus rau hauv lub cylindrical siv lead ua, uas 1s ces txias, hlais rau hauv wafers, thiab polished los muab cov substrates rau semiconductors Tsis tas li ntawd, tungsten hlau yog siv nyob rau hauv cov probes siv rau. sim integrated circuits thaum lawv tseem nyob rau hauv monocrystalline wafer daim ntawv.
Lwm daim ntawv thov kev lag luam uas tungsten hlau cov khoom kub siab ua pov thawj yog qhov tseem ceeb yog nyob rau hauv cov borescopes siv los ntsuas qhov chaw sab hauv ntawm qhov kub thiab txias heev. Rau cov cheeb tsam uas tsis tuaj yeem siv tau los ntawm lwm txoj kev, cov borescopes no feem ntau siv rau hauv kev tshuaj xyuas cov cav, turbines, kav, thiab tso tsheb hlau luam.
Nrog nws tsis tshua muaj vapor siab nyob rau hauv qhov kub thiab txias, tungsten hlau kuj yog siv nyob rau hauv lub tshuab nqus tsev metalizing coils siv nyob rau hauv cov txheej txheem ntawm txheej txheej ntawm cov khoom yas uas tsis tshua muaj nqi - xws li cov khoom ua si, hniav nyiaj hniav kub, ntim cov tshuaj pleev ib ce, thiab cov hniav me me - nrog. hlau evaporates. Cov khoom lossis cov khoom raug muab tso rau hauv lub tshuab nqus tsev nrog cov txheej hlau, uas yog rhuab nrog cov coils kom txog thaum nws tau evaporated; lub vapor settles ntawm cov khoom / qhov chaw, sai thiab tag txheej txheej nrog ib tug nyias, niaj hnub zaj duab xis ntawm cov hlau evaporate.
