Molybdenum rhaub

 

Molybdenum Rhaub yog lub siab ua haujlwm siab ua haujlwm cua sov, tshwj xeeb tshaj yog tsim los rau kev kub siab heev - cov txheej txheem kub hauv lub tshuab nqus tsev lossis tiv thaiv huab cua (xws li hydrogen lossis argon). Leveraging lub cev lub cev ntawm molybdenum hlau, xws li nws siab melting point (kwv yees li 2610 degree), siab kub lub zog, tsis tshua muaj vapor siab, zoo heev thermal conductivity thiab hluav taws xob conductivity, nws muaj peev xwm ua tau kom ruaj khov, ntshiab thiab muaj txiaj ntsig cua sov tshaj qhov txwv ntawm cov khoom cua sov zoo tib yam. Nws yog ib qho khoom siv tseem ceeb hauv kev txiav - ntug kev lag luam thiab kev tshawb fawb tshawb fawb ntau lawm.

 

 

 

1.Outstanding kub kuj ua tau zoo

Kev khiav hauj lwm kub ntawm lub rhaub no feem ntau tuaj yeem ncav cuag 1600 degree. Qhov zoo tsim molybdenum cua sov chamber tuaj yeem tiv taus qhov kub siab tshaj 2000 degree, ua tau raws li qhov yuav tsum tau muaj ntawm cov txheej txheem huab.

 

2. Precise Temperature Control

Ua tsaug rau cov thermal conductivity siab txog li 142 W / (m·K) ntawm cov hlau molybdenum, cov cua sov no tuaj yeem tsim los ntawm cov duab nyuaj xws li kauv, tswj qhov kub sib txawv hauv qhov cub. Piv txwv li, nyob rau hauv ib qho -crystal silicon rauv nrog 800mm txoj kab uas hla ntawm lub cub tawg chamber, qhov kub ntawm qhov sib txawv yuav raug txo kom nyob rau hauv 8 degree, ho txhim kho cov khoom yield thiab kev ua tau zoo.

 

3. Carbon-dawb siab -purity ib puag ncig

Tsis zoo li graphite heaters, molybdenum cua sov lub caij no tsis tsim hydrocarbons nyob rau hauv hydrogen los yog lwm yam cua, yog li zam kom tsis txhob muaj kab mob ntawm lub workpiece. Nws yog tshwj xeeb tshaj yog haum rau kev ua cov pa roj carbon - cov ntaub ntawv rhiab heev xws li stainless hlau thiab titanium, kom ntseeg tau lub siab purity ntawm ob lub tshuab nqus tsev thiab cov txheej txheem cua.

 

4. Cov zis ruaj khov thiab lub neej ntev

Kev tiv thaiv kub coefficient ntawm molybdenum yog qis (kwv yees li 0.0043 / degree), ua rau muaj kev hloov pauv me me hauv qhov ntsuas kub. Lub zog tso zis yog ruaj khov, thiab kev tswj qhov kub thiab txias tuaj yeem ncav cuag ± 4℃(cov cuab yeej siv niaj hnub ± 15 degree). Nws muaj zog tiv thaiv kom nkag tau ntawm qhov kub thiab txias thiab qis evaporation tus nqi (kwv yees li 0.015g / h·m²). Tom qab ua haujlwm tas li rau 5000 teev, qhov cua sov no tseem tswj tau 92% ntawm qhov kev ua haujlwm thawj zaug, txo cov nqi tu.

 

5. Zog-txuag thiab siv tau-txo kev tsim

Cov cua kub no optimizes cov qauv hluav taws xob tiv thaiv kom txo tau cov cua sov. Qhov piv txwv qhia tau hais tias tom qab siv lub tshuab cua sov molybdenum, kev siv hluav taws xob rau ib lub qhov cub ua haujlwm tuaj yeem raug txo los ntawm 18%, pab cov tuam txhab ua tiav kev tsim khoom ntsuab thiab cov nqi kho kom zoo.

 

 

 

1.Nqus cua sov kho cua sov

Cov khoom siv cua sov yog siv rau cov khoom siv kho mob thiab kev sib tsoo ntawm cov khoom tseem ceeb hauv aerospace thiab nuclear zog teb (xws li titanium alloys, beryllium bronze), nrog rau qhov kub siab tshaj plaws txog 1500 degree, ua kom lub ntsej muag ci thiab tsis muaj oxidation ntawm lub workpiece.

 

2. Cov khoom siv Sintering thiab Crystal loj hlob

Hauv kev tsim cov khoom siv siab tshaj -cov ntaub ntawv ua tau zoo xws li silicon carbide ceramics thiab aluminium nitride substrates, Cov khoom cua sov muab qhov chaw thermal ruaj khov txog li 2050 degree; nws kuj tseem siv rau hauv sapphire thiab ib zaug -crystal silicon loj hlob rauv kom ntseeg tau tias siv lead ua zoo thiab kev ua haujlwm zoo.

 

3. Iav Melting thiab ua

Raws li cov electrode rau lub iav hluav taws xob melting rauv, qhov cua sov no yog ncaj qha rau hauv lub khob kua rau cua sov. Nws lub zog efficiency yog siab dua li ntawm cov tsoos nplaim taws kub, thiab cov uniformity ntawm cov khoom kub yog zoo dua. Tib lub sijhawm, nws txhim kho kev nyab xeeb ntawm qhov chaw ua haujlwm.

 

4. High Purity thiab cov txheej txheem tshwj xeeb

Hauv cov txheej txheem xws li hlau txhaj tshuaj molding (MIM), thermal degreasing, thiab siab -kub pyrolysis uas yuav tsum tau muaj cov pa roj carbon- ib puag ncig dawb, cov cua kub tiv thaiv kev cuam tshuam nrog graphite, ua kom cov txheej txheem purity. Nws yog qhov kev xaiv zoo tshaj plaws rau kev tuav cov khoom siab -precision.
