MOCVD Substrate Heater, Zinthu Zowotchera za MOCVD

Kufotokozera Kwachidule:

Zida zotenthetsera za graphite zimagwiritsidwa ntchito mung'anjo yotentha kwambiri ndi kutentha komwe kumafikira madigiri 2200 pamalo opanda mpweya ndi digirii 3000 m'malo odetsedwa komanso oyika mpweya.
Zofunikira zazikulu za chowotcha cha graphite:
1. kufanana kwa kapangidwe ka kutentha.
2. zabwino madutsidwe magetsi ndi mkulu magetsi katundu.
3. kukana dzimbiri.
4. inoxidizability.
5. mkulu mankhwala chiyero.
6. mphamvu zamakina apamwamba.
Ubwino wake ndi wogwiritsa ntchito mphamvu, wamtengo wapatali komanso wocheperako.
Titha kupanga odana ndi makutidwe ndi okosijeni ndi moyo wautali graphite crucible, nkhungu graphite ndi mbali zonse za chowotcha graphite.
Zigawo zazikulu za chowotcha cha graphite:

Thegraphite chowotchazigawo zikuluzikulu ntchito mu ng'anjo mkulu kutentha ndi kutentha kufika madigiri 2200 pa zingalowe chilengedwe ndi 3000 digiri mu deoxidized ndi anaikapo mpweya chilengedwe.
Mbali zazikulu zagraphite chowotcha:
1. kufanana kwa kapangidwe ka kutentha.
2. zabwino madutsidwe magetsi ndi mkulu magetsi katundu.
3. kukana dzimbiri.
4. inoxidizability.
5. mkulu mankhwala chiyero.
6. mphamvu zamakina apamwamba.
Ubwino wake ndi wogwiritsa ntchito mphamvu, wamtengo wapatali komanso wocheperako.
Titha kupanga anti-oxidation ndi moyo wautali wautali wa graphite crucible, nkhungu ya graphite ndi mbali zonse za graphite.chotenthetsera.

Chotenthetsera cha graphite cha ng'anjo yamagetsi chimakhala ndi mphamvu yokana kutentha, kukana kwa okosijeni, kuwongolera bwino kwamagetsi komanso kulimba kwamakina. Titha makina osiyanasiyana chotenthetsera graphite malinga ndi mapangidwe a makasitomala.
