Koj tuaj yeem pom tungsten ntawm qhov chaw ua haujlwm thaum twg los xij.Vim tias tsis muaj lwm yam hlau tuaj yeem sib piv nrog tungsten thaum nws tuaj yeem tiv taus cua sov.Tungsten muaj qhov siab tshaj plaws melting point ntawm tag nrho cov hlau thiab yog li ntawd kuj haum rau high-temperature daim ntaub ntawv.Nws kuj yog tus cwj pwm los ntawm qhov tsis tshua muaj coefficient ntawm thermal expansion thiab qib siab ntawm qhov ruaj khov.Tungsten yog xyaum indestructible.Piv txwv li, peb siv cov khoom siv no los tsim cov khoom siv hluav taws xob kub kub, cov khoom siv hluav taws xob thiab cov khoom siv rau kev siv hauv kev kho mob thiab nyias-zaj duab xis technology.A cov khoom siv nrog cov txuj ci tshwj xeeb.
Cov ntawv thov tshwj xeeb hauv kev lag luam uas peb siv tungsten qhia txog cov khoom tshwj xeeb ntawm cov khoom.Peb nthuav qhia luv luv peb ntawm cov hauv qab no:
Zoo heev creep kuj thiab siab purity.
Peb cov tungsten yog nrov heev rau siv nyob rau hauv melting thiab solidification hlab ntsha nyob rau hauv lub teb ntawm sapphire siv lead ua kev loj hlob.Nws qib siab ntawm purity tiv thaiv kev kis kab mob ntawm sapphire siv lead ua thiab nws txoj kev nkag siab zoo tuaj yeem lav cov khoom lag luam qhov ruaj khov.Txawm tias qhov kub thiab txias heev, cov txiaj ntsig ntawm cov txheej txheem tseem nyob ruaj khov.
High purity thiab zoo hluav taws xob conductivity.
Nrog rau qhov qis tshaj coefficient ntawm thermal expansion ntawm tag nrho cov hlau thiab ib theem siab ntawm hluav taws xob conductivity, peb tungsten yog cov khoom zoo meej rau cov ntawv nyias nyias.Nws qib siab ntawm cov hluav taws xob conductivity thiab tsis tshua muaj qhov sib txawv rau cov khaubncaws sab nraud povtseg txhais tau hais tias tungsten yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob nyias nyias ntawm cov khoom siv hauv cov ntxaij vab tshaus TFT-LCD.Thiab, ntawm chav kawm, peb kuj muaj peev xwm muab koj cov ntaub ntawv txheej nyob rau hauv daim ntawv ntawm ultra-high purity sputtering lub hom phiaj.Tsis muaj lwm lub chaw tsim khoom muaj peev xwm muab cov phiaj xwm tungsten hauv qhov loj dua.
Lub neej ntev kev pab cuam thiab lub siab melting point heev.
Nrog lawv cov kev pabcuam ntev nyob txawm tias qhov kub thiab txias, peb tungsten melting crucibles thiab mandrel shafts muaj peev xwm tiv taus txawm tias quartz iav melts yam tsis muaj teeb meem.Ua tsaug rau qhov zoo tshaj plaws purity ntawm peb cov tungsten, peb tuaj yeem ntseeg tau los tiv thaiv kev ua npuas lossis tawg ntawm quartz melts.
