Khoom Description
Ib yam khoom tungsten nyias muaj li ntawm tungsten ntshiab lossis tungsten alloy yog hu ua tungsten koob. Nws tuaj yeem siv los ua qhov ntsuas ntsuas thiab ua cov khoom siv electrode hauv argon arc vuam txheej txheem. Nws muaj zog conductivity thiab zoo kub kuj yog nws qhov zoo. Nyob rau hauv cov xwm txheej glow discharge, carbonyl tungsten vapor yog siv los ua tungsten koob. Nyob rau hauv chav tsev kub tungsten substrates, koob kev loj hlob yuav siv sij hawm qhov chaw nyob rau hauv lub 1500 degree K ntau yam; Txawm li cas los xij, thaum kub dhau mus lossis qis dua ~ 1100 degree K, koob morphology thiab crystallization xeev hloov. Cov khoom siv tungsten particle muaj cov morphology ntawm whiskers ntawm qhov kub thiab txias thiab cov ceg ntoo ntawm qhov kub thiab txias.Nyob rau hauv cov khoom siv scientific, tungsten koob yog ultra-ntse electrodes muaj li ntawm ib tug refractory alloy. Lub electrode yog taw tes rau ntawm lub hauv paus thiab blunt ntawm lub ntsis. Nws tuaj yeem rov ua dua los tshem tawm thiab hloov cov molten oxidizer tank pas nrig. Nws yog tsim los ntawm refractory alloy nyob rau hauv ib tug loj electrode lub tog raj kheej perpendicular mus rau lub axis ntawm kev sib hloov.
Muaj ob txoj kev tsim khoom tseem ceeb rau tungsten koob: ib qho yog cov txheej txheem hlau txhaj tshuaj molding, thiab lwm yam yog cov txheej txheem kos duab hlau.
Cov txheej txheem yooj yim ntawm cov txheej txheem hlau txhaj tshuaj molding yog thawj zaug knead cov hmoov khoom thiab cov organic sib npaug sib npaug, granulate nws, thiab tom qab ntawd txhaj rau hauv pwm kab noj hniav nrog lub tshuab txhaj tshuaj molding kom khov thiab tsim.
Tom qab ntawd cov binder nyob rau hauv lub preform yog muab tshem tawm los ntawm cov tshuaj los yog thermal decomposition, thiab thaum kawg qhov kawg tungsten koob khoom yog tau los ntawm sintering thiab densification.
Cov txheej txheem kev kos duab yog los ua kom sov cov khoom siv hlau kom txog thaum nws dhau los ua cov yas, ces ncab nws mus rau txoj kab uas xav tau, thiab thaum kawg txias nws los ntawm shearing.

Yam khoom
Cov koob tungsten tuaj yeem muab faib ua puag ncig tungsten koob thiab taw tes tungsten koob raws li lawv cov duab:
puag ncig pas nrig
Lub round pas nrig-zoo li tus tungsten koob muaj ib tug qauv slender thiab ib tug metallic nto. Siv rau argon arc vuam electrodes. Argon arc vuam tshuab yog qhov loj tshaj plaws thiab feem ntau siv vuam tshuab hauv tsev thiab txawv teb chaws. Hauv particular, phau ntawv tungsten arc vuam tau dhau los ua ib txoj hauv kev tseem ceeb rau kev vuam ntau yam hlau.
Thaum vuam, ib qho arc yog tsim los ntawm tungsten electrode thiab cov khoom ua haujlwm, thiab cov hlau muab tub lim yog pub los ntawm ib sab. Nyob rau hauv qhov kev txiav txim ntawm arc tshav kub, muab tub lim hlau thiab lub workpiece yaj ua ke los tsim ib tug weld.
Txhawm rau tiv thaiv lub melting thiab hlawv ntawm electrode, vuam tam sim no tsis tuaj yeem loj dhau. Yog li ntawd, tungsten arc vuam feem ntau yog tsim rau vuam nyias daim hlau hauv qab 4 hli, xws li cov yeeb nkab pob qij txha thiab kev sib txuas ntawm cov kav dej thiab cov ntawv raj.
nrog taw tes
tungsten koob nrog cov lus qhia taw qhia yog siv los ua ntsuas ntsuas. Xws li cov tshuab ntsuas plaub-ntu digital, uas yog cov khoom siv ntsuas ntau lub hom phiaj uas siv plaub-txoj kev ntsuas kev ntsuas.
Cov cuab yeej no yog tsim los ua raws li lub teb chaws tus qauv rau kev kuaj lub cev ntawm ib leeg siv lead ua silicon thiab siv rau American ASTM tus qauv. Nws yog ib qho cuab yeej tshwj xeeb rau kev ntsuas qhov kev tiv thaiv thiab daim ntawv tsis kam (daim ntawv tsis kam) ntawm cov khoom siv semiconductor.
Nws yog qhov tsim nyog rau kev sim cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob semiconductor, cov khoom siv hluav taws xob semiconductor, cov chaw tshawb fawb tshawb fawb, thiab cov tsev kawm qib siab.
Cov khoom siv
Cov ntawv thov tseem ceeb rau cov koob tungsten suav nrog kev ua haujlwm ib zaug, txiav cov khoom sib tsoo, thiab kos cov hlau nto. Cov koob no feem ntau khoov lossis tawg vim lawv qhov brittleness heev. Particle txiav yuav tsum ua kom tiav tes ua haujlwm. Cov koob tungsten no yog siv los tshuab iav thiab siv lead ua embryos ntxiv rau kev txiav cov khoom.
Nws kuj yog siv dav hauv lub ntiaj teb tsis tshua muaj, lub tshuab nqus tsev, iav fiber ntau, muaj ceramics, petrochemical, aviation, aerospace, machinery, electronics, teeb pom kev zoo, LED, silicon cov khoom siv, hnub ci photovoltaic, semiconductor, nqus txheej thiab lwm yam lag luam, tshwj xeeb tshaj yog siv los rau lub tshuab nqus tsev cua sov Chamber, thermal teb yam ntawm sapphire siv lead ua kev loj hlob.
Packing Kev xa khoom
1. Siv lub thawv ntoo uas tsis muaj kev puas tsuaj rau kev ntim khoom.
2. Kev xa tawm ntawm av (tsheb ciav hlau), hiav txwv, thiab nthuav qhia huab cua freight raws li qhov hnyav ntawm pob khoom thiab cov kev xav tau ntawm cov neeg siv khoom.
3. Peb tuaj yeem muab rau txhua qhov chaw nres nkoj Suav rau kev thauj mus los hauv hiav txwv.
