Kev cai 99.95% Tungsten W Nkoj rau Evaporation
Tungsten nkoj siv rau evaporation feem ntau yog tsim los ntawm cov hmoov hlau metallurgy txheej txheem.Hauv qab no yog cov kauj ruam dav dav rau kev tsim lub nkoj tungsten rau evaporation:
Kev xaiv cov khoom siv raw: Xaiv cov hlau purity siab tungsten hmoov, feem ntau muaj purity ntawm 99.95%, raws li cov khoom tseem ceeb rau kev tsim cov nkoj tungsten.High purity ua kom muaj kev sib kis tsawg tsawg thaum evaporation.Mixing: Ua tib zoo sib xyaw tungsten hmoov siv cov cuab yeej tshwj xeeb kom ua tiav qhov sib xyaw ua ke thiab cov khoom siv zoo ib yam.Compaction: Mixed tungsten hmoov yog muab tso rau hauv pwm thiab kev kub siab yog thov, feem ntau ntawm txias isostatic pressing (CIP) los yog uniaxial nias.Cov txheej txheem compacts cov hmoov mus rau hauv ib tug ntom thiab coherent zoo uas zoo li lub nkoj xav tau geometry.Pre-sintering: Compacted tungsten qhov chaw yog pre-sintered ntawm qhov kub thiab txias nyob rau hauv ib qho chaw tswj, cia cov hmoov particles rau daim ntawv cog lus thiab tsim ib tug ruaj khov qauv ntawm lub zog.Sintering: Cov khoom ua ntej sintered yog tom qab ntawd raug rau cov txheej txheem kub kub sintering hauv lub tshuab nqus tsev lossis hydrogen cua.Cov txheej txheem no ntxiv densifies cov khoom, tshem tawm cov seem pores, thiab txhawb kev loj hlob ntawm cov nplej, uas ua rau lub nkoj tungsten muaj zog thiab ntom.Machining thiab xov: Tom qab sintering, lub nkoj tungsten tuaj yeem ua haujlwm ua haujlwm xws li milling, tig lossis sib tsoo kom ua tiav qhov kawg qhov ntev, grooves thiab nto tiav yuav tsum tau ua kom muaj txiaj ntsig ntawm cov khoom siv thaum lub sij hawm evaporation.Kev Tswj Xyuas Zoo: Cov nkoj tungsten tiav tau raug tshuaj xyuas rau qhov tseeb qhov tseeb, kev ncaj ncees ntawm qhov chaw thiab cov khoom siv purity kom ntseeg tau tias lawv ua tau raws li qhov yuav tsum tau ua rau kev siv evaporation.
Thoob plaws hauv cov txheej txheem tsim khoom, kev tswj xyuas nruj nruj thiab kev saib xyuas cov txheej txheem yog qhov tseem ceeb los xyuas kom meej tias lub nkoj tungsten ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem nqus tsev vacuum.Lub nkoj tungsten ua rau muaj peev xwm tiv taus qhov kub thiab txias ib puag ncig, ua rau nws tsim nyog rau ntau yam kev siv lub tshuab nqus tsev vacuum thoob plaws hauv kev lag luam.
Cov nkoj tungsten feem ntau siv rau hauv cov txheej txheem nqus evaporation, tshwj xeeb tshaj yog nyias zaj duab xis deposition thiab semiconductor manufacturing.Nov yog qee qhov kev siv tseem ceeb ntawm tungsten nkoj evaporation:
Nyias zaj duab xis deposition: Tungsten tej nkoj nquam yog siv nyob rau hauv lub cev vapor deposition (PVD) txheej txheem evaporate hlau thiab lwm yam ntaub ntawv mus rau ib tug substrate los ua nyias films ntawm tswj thickness thiab muaj pes tsawg leeg.Qhov no yog dav siv nyob rau hauv zus tau tej cov hluav taws xob thiab kho qhov muag coatings raws li zoo raws li cov hniav thiab haumxeeb kho deg.Semiconductor Manufacturing: Hauv kev lag luam semiconductor, tungsten nkoj feem ntau yog siv los tso cov ntaub ntawv nyias nyias xws li txhuas, titanium thiab lwm cov txheej hlau ntawm silicon wafers.Qhov no yog ib kauj ruam tseem ceeb hauv kev tsim cov khoom siv hluav taws xob sib txuas, microelectromechanical systems (MEMS), thiab lwm yam khoom siv hluav taws xob.Kev Tshawb Fawb thiab Kev Txhim Kho: Cov nkoj tungsten tau siv hauv chav kuaj thiab R & D ib puag ncig kom evaporate cov ntaub ntawv los kawm lawv cov khoom, tsim cov ntaub ntawv nyias nyias, thiab tshawb xyuas cov txheej txheem txheej txheej tshiab.Qhov no suav nrog cov tsev kawm tshawb fawb, tsoomfwv cov chaw sim thiab cov chaw R & D muaj.Tungsten lub siab melting point thiab thermal stability zoo ua rau nws yog ib qho khoom siv zoo tshaj plaws rau lub nkoj zoo li crucibles siv hauv cov txheej txheem evaporation.Tungsten tej nkoj nquam tuaj yeem tiv taus qhov kub siab uas yuav tsum tau ua kom evaporate ntau yam ntawm cov ntaub ntawv yam tsis muaj qhov tseem ceeb deformation lossis degradation, kom ntseeg tau tias cov yeeb yaj kiab zoo sib xws thiab txhim khu kev qha.Tsis tas li ntawd, lawv cov inertness thiab tsis kam mus rau cov tshuaj tiv thaiv ua rau lawv haum rau evaporating nquag thiab alloying ntsiab nyob rau hauv kev tswj ib puag ncig.
Zuag qhia tag nrho, tungsten nkoj ua si lub luag haujlwm tseem ceeb hauv kev ua kom cov yeeb yaj kiab nyias nyias thiab yog ib qho tseem ceeb hauv ntau qhov kev lag luam uas vam khom lub tshuab nqus tsev vacuum los tsim cov khoom siv siab heev thiab cov khoom siv hluav taws xob.
