Tungsten Nqus Tsev Sib cuag piav qhia
Cov hluav taws xob sib txuas tsim hluav taws xob sib txuas ntawm cov khoom hauv kev tiv thaiv overvoltage, relays thiab keyboards. Cov kev xav tau rau kev sib txuas lus sib txawv nyob ntawm qhov hloov hluav taws xob, hloov hluav taws xob, hloov zaus, tsis tu ncua tam sim no, thiab pib thiab tawg tam sim no. Raws li, qhov yuav tsum tau muaj rau cov neeg sib cuag thiab cov txheej txheem los xyuas kom meej tias lawv muaj kev nyab xeeb ua haujlwm sib txawv. Txhawm rau tiv thaiv oxidation, cov neeg sib cuag tuaj yeem ua rau corrosion resistant los ntawm coatings nrog precious hlau los yog kev khiav hauj lwm cov kev sib cuag nyob rau hauv lub nqus tsev vacuum, inert gas los yog roj. Lwm yam teeb meem muaj xws li kev sib cuag yaig, yaig los ntawm qhov hluav taws xob flashover, lossis arcing thiab vuam ntawm lub zog siab. Cov teeb meem no tuaj yeem daws tau los ntawm kev siv cov hlau refractory zoo li tungsten.
Nyob rau tib lub sijhawm yuav tsum tau ua kom ntseeg tau tias qhov kev sib cuag tsis zoo. Txawm li cas los xij, qhov no tuaj yeem muab tau los ntawm cov khoom siv qis tab sis cov khoom siv hluav taws xob zoo xws li tooj liab thiab nyiaj. Raws li qhov yuav tsum tau ua, cov khoom ntawm cov hlau melting siab yog ua ke nrog cov hlau uas muaj cov khoom siv hluav taws xob ntau. Yog li ntawd, alloys yog tsim nyob rau hauv uas ob lub ntsiab yog tam sim no nyob rau hauv ib tug haum ratio rau ib leeg. Qhov no tsim kev sib cuag nrog vuam zoo heev thiab kev sib cuag zoo.

Peb kuj muab peb WCu hloov kev sib cuag hauv VFG (Nqus Fine Grained) zoo. Qhov no txhais tau tias lawv yog ultrapure thiab muaj hluav taws xob zoo heev. Raws li qhov yuav tsum tau ua, peb muaj ntau yam VFG cov ntaub ntawv hauv peb qhov ntau nrog ob qhov sib txawv ntawm tooj liab:
VFG10 (tungsten 90 feem pua ntawm qhov hnyav, tooj liab 10 feem pua ntawm qhov hnyav)
VFG20 (tungsten 80 feem pua ntawm qhov hnyav, tooj liab 20 feem pua ntawm qhov hnyav)
Peb qhov kev sib txuas sib txuas ua los ntawm WCCu30 yog ib qho txiaj ntsig zoo rau WCAg thiab tseem yog tsim los ntawm cov khoom siv roj tsawg rau siv hauv lub tshuab nqus tsev.
