Monga zida zofunikira zoyesera, carbon bonded silicon carbide crucible imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga chemistry, metallurgy, electronics, and high-temperature kuyesera chifukwa cha ubwino wake wa kukana kutentha, kukana kwa dzimbiri, ndi kuyendetsa bwino kwa kutentha. Nkhaniyi ifotokoza mwatsatanetsatane kagwiritsidwe ntchito ka silicon carbide crucible m'magawo awa.
### 1. Kugwiritsa ntchito gawo la chemistry
1. **Kutentha kwa reactants **
Poyesera mankhwala, ma graphite crucibles amagwiritsidwa ntchito nthawi zambiri kutenthetsa ma reactants chifukwa cha zochita za mankhwala. Kutentha kwake kwabwino kwambiri komanso kukana kutentha kumawathandiza kuti azigwira ntchito mokhazikika m'malo otentha kwambiri popanda kupunduka kapena kuwonongeka.
2. **Kutentha kwambiri**
Zinthu zina za mankhwala zimafuna kutentha kwambiri. Mwachitsanzo, popanga mpweya, potaziyamu superoxide iyenera kutenthedwa mpaka 1000°C. Chombo cha graphite crucible chimatha kupirira kutentha kwakukulu koteroko, kuonetsetsa kuti kuyesako kukuyenda bwino.
3. **Corrosion resistance**
Pamachitidwe opangidwa ndi ma acid amphamvu kapena maziko, magalasi wamba amawonongeka mosavuta, koma ma graphite crucibles amalimbana bwino ndi dzimbiri ndipo amatha kuchita izi mosatekeseka.
### 2. Kugwiritsa ntchito m'munda wazitsulo
1. **Kutentha kwambiri kusungunuka**
Ma graphite crucibles amagwiritsidwa ntchito kwambiri poyesa kusungunuka kwapamwamba kwambiri m'munda wazitsulo. Mwachitsanzo, pokonza zitsulo, ziyenera kutenthedwa pamwamba pa malo osungunuka. Graphite crucible imatha kutentha mokhazikika ndikusunga kutentha komwe kumafunikira.
2. **Kusakaniza Zinthu**
Muzoyesera zina zazitsulo, zinthu ziyenera kuwonjezeredwa kuzitsulo zosungunuka kuti zisakanizike. graphite crucible sikuti amangosunga kutentha kwambiri komanso amatsimikizira kupita patsogolo kwabwino kwa kusakaniza.
3. **Kuyesera Kwapadera Kwachitsulo **
Kuyesera kwina kwapadera kumafuna kuti zotengerazo zizikhala zokhazikika pakatentha kwambiri, ndipo ma graphite crucibles ndiabwino kwambiri pazotengera zotentha kwambiri.
### 3. Kugwiritsa ntchito pamagetsi
1. ** Chithandizo cha Kutentha Kwambiri **
Mukapanga zida za semiconductor, zowotcha za silicon ziyenera kutenthedwa mpaka kutentha kopitilira 1,000.°C. Graphite crucible angapereke chofunika mkulu-kutentha chilengedwe kuonetsetsa bwino akamaliza ndondomeko masitepe.
2. **Kutentha kwambiri sintering**
Pofuna kupititsa patsogolo machitidwe a zipangizo zamagetsi, kutentha kwapamwamba kumafunika. Graphite crucible imatha kugwira ntchito mokhazikika pansi pamikhalidwe yotentha yotereyi ndipo ndi chidebe choyezera bwino.
3. **Kuyesera Kwapadera Kwamagetsi **
M'mayesero apadera amagetsi, kukhazikika kwa kutentha kwa graphite crucible kumapangitsa kuti chidebe choyesera chofunikira kwambiri.
###4. Mapulogalamu m'munda woyesera kutentha kwakukulu
1. ** Chithandizo cha kutentha kwambiri kwa zipangizo **
Pokonzekera zida za ceramic, ufa wa ceramic uyenera kutenthedwa pamwamba pa kutentha kwa sintering. Ma graphite crucibles amachita bwino kwambiri panthawi yonse yotentha ndi kukonza kutentha.
2. **Kuwonjezera magwiridwe antchito**
Zida zina zimafuna chithandizo cha kutentha kwambiri kuti ziwongolere katundu wawo. Mwachitsanzo, pokonza diamondi, gwero la kaboni liyenera kutenthedwa mpaka 3000°C. The graphite crucible amatha kugwira ntchito mokhazikika pa kutentha kwakukulu kotereku, kuonetsetsa kuti zinthu zikuyenda bwino.
3. **Chidebe choyesera kutentha kwambiri **
Poyesera kutentha kwambiri, graphite crucible ndi chidebe chofunikira kwambiri, ndipo kukhazikika kwake kwapamwamba kwambiri kumatsimikizira kuti kuyesako kukuyenda bwino.
Monga chida choyesera bwino m'magawo ambiri, graphite crucible imagwira ntchito yosasinthika m'magawo osiyanasiyana aukadaulo ndi zabwino zake zapadera. Kaya mukuchita mankhwala, kusungunula zitsulo, kukonza zamagetsi, kapena kuyesa kutentha kwakukulu, ma graphite crucibles amapereka chitsimikizo cholimba cha kafukufuku wa sayansi ndi kupanga mafakitale ndi ntchito yawo yapamwamba.
