Tungsten hlau yog cov hlau hlau ua los ntawm tungsten. Nws muaj ntau yam kev siv vim nws qhov siab melting point, kub tsis kam, thiab corrosion kuj. Tungsten hlau feem ntau yog siv los ua cov khoom siv hluav taws xob, teeb pom kev zoo, lub tshuab nqus tsev thiab lwm yam khoom siv.
2. Kev siv tungsten hlau
Cov khoom siv hluav taws xob:tungsten hlautuaj yeem siv los ua cov khoom siv hluav taws xob, xws li resistors, xov hlau kub, electrodes, thiab lwm yam. Hauv kev tsim cov qij, tungsten hlau yog ib qho tseem ceeb ntawm cov teeb pom kev zoo. Nws lub siab melting point tuaj yeem ua kom ntseeg tau tias lub teeb lub teeb ua haujlwm ib txwm nyob ntawm qhov kub thiab txias, thiab qis evaporation tus nqi ntawm tungsten hlau tuaj yeem ua kom lub neej ntawm lub teeb.
Teeb pom kev zoo: Tungsten hlau kuj feem ntau siv hauv cov khoom siv teeb pom kev zoo. Piv txwv li, tsheb headlights, theem teeb, thiab lwm yam yuav tsum tau tungsten hlau.
Lub tshuab nqus tsev hluav taws xob: Hauv cov khoom siv hluav taws xob nqus, tungsten hlau yog siv ntau dua. Nws tuaj yeem siv los ua cathodes, anodes, cua sov lub cev, thiab lwm yam.
Kev Kho Mob: Vim tias tungsten hlau muaj qhov kub thiab txias, nws kuj muaj qee yam kev siv hauv kev kho mob. Piv txwv li, qee cov khoom siv kho mob xav tau tungsten hlau, xws li X-ray raj.
3. Qhov zoo ntawmWAL Tungsten Hlau
-1. Kev ruaj ntseg kub kub: Tungsten hlau muaj lub siab melting point thiab tuaj yeem tiv taus kub corrosion thiab thermal expansion.
-2. Tsawg evaporation tus nqi: tungsten hlau tsis yooj yim rau volatilize ntawm qhov kub thiab txias, uas yuav pab kom ntev kev pab cuam lub neej ntawm cov khoom.
-3. Corrosion kuj: Tungsten hlau muaj kev ruaj ntseg zoo hauv qee qhov acid thiab alkali corrosion ib puag ncig.
-4. Lub zog siab: Tungsten hlau muaj lub zog siab thiab tsis yooj yim rau deform nyob rau hauv qhov kub thiab txias.
4. Kev siv tungsten hlau hauv kev lag luam hluav taws xob
Tungsten hlau muaj ntau yam kev siv tseem ceeb hauv kev lag luam hluav taws xob, qee qhov suav nrog:
Kev tsim khoom siv hluav taws xob: Tungsten hlau feem ntau yog siv los tsim cov khoom siv hluav taws xob xws li cov khoom siv hluav taws xob, cov raj hluav taws xob, thiab cov thermionic emitters. Vim nws qhov siab melting point thiab stability, tungsten hlau tuaj yeem tiv taus qhov kub thiab txias hauv cov ntawv thov no, tso cai rau cov khoom siv hluav taws xob ua haujlwm ruaj khov.
Resistance wire: Tungsten hlau yog dav siv los ua cov hlau tsis kam, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov kub. Nws tuaj yeem siv rau hauv cov khoom cua sov xws li lub qhov cub, qhov cub, hluav taws xob rauv, thiab hluav taws xob melting furnaces.
Lub tshuab nqus tsev hluav taws xob: Tungsten hlau kuj tseem siv hauv cov khoom siv hluav taws xob xws li phom hluav taws xob, microwave amplifiers, thiab microwave oscillators. Vim nws oxidation tsis kam thiab siab melting point, nws ua tau zoo nyob rau hauv lub tshuab nqus tsev tej yam kev mob.
Electron microscope: Cov kab hluav taws xob hauv lub tshuab hluav taws xob feem ntau muaj tungsten hlau. Tungsten hlau muaj peev xwm tsim tau lub teeb ci hluav taws xob siab rau kev soj ntsuam xyuas thiab ntsuas.
Vuam thiab txiav: Tungsten hlau feem ntau yog siv los ua electrode rau arc vuam thiab plasma txiav. Nws qhov siab melting point thiab corrosion kuj ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau cov ntawv thov no.
Cov khoom siv hluav taws xob photoelectric: Tungsten filaments kuj tau siv hauv kev tsim cov khoom siv hluav taws xob, xws li photodiodes thiab photomultiplier tubes, uas ntes cov teeb liab teeb liab thiab hloov mus rau hauv cov teeb liab hluav taws xob.
Electron beam fuse manufacturing: Tungsten filaments kuj tseem siv los ua cov khoom siv hluav taws xob hluav taws xob, uas yog siv los tiv thaiv cov khoom siv hluav taws xob los ntawm kev puas tsuaj los ntawm cov hluav taws xob ntau dhau.
