MOCVD Substrate Heater, Zinthu Zowotchera za MOCVD
Chowotcha cha graphite:
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 mawonekedwe a 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 magawo onse a chowotcha cha graphite.

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.
