Graphite crucible ndi chida wamba chasayansi, chomwe chimagwiritsidwa ntchito kwambiri mu chemistry, zitsulo, zamagetsi, zamankhwala ndi mafakitale ena. Zimapangidwa ndi chiyero chapamwamba cha graphite ndipo chimakhala ndi kutentha kwapamwamba kwambiri komanso kukhazikika kwa mankhwala.
Zotsatirazi ndikuyambitsa mwatsatanetsatane kwa graphite crucible materials:
1. Zinthu zamtengo wapatali za graphite: Chophimba cha graphite chimapangidwa ndi chiyero chapamwamba cha graphite kuti chiwonetsetse ntchito yabwino ya mankhwalawa. Zida zoyera kwambiri za graphite zimakhala ndi zonyansa zochepa, kutentha kwapamwamba kwambiri komanso kukana kutentha kwambiri, ndipo zimatha kupirira kutentha kwakukulu ndi malo a mankhwala.
2. Kukhazikika kwa kutentha kwapamwamba: Graphite crucible imakhala ndi kutentha kwapamwamba kwambiri ndipo imatha kupirira kutentha kwambiri mpaka madigiri 3000 Celsius. Izi zimapangitsa kukhala koyenera kwa kuyesa kwa kutentha kwapamwamba ndikugwiritsira ntchito ndondomeko, monga kukonzekera zitsanzo zosungunuka ndi khalidwe la kutentha kwapamwamba.
3. Chemical bata: graphite crucible chuma ali ndi dzimbiri kukana kwa mankhwala ambiri. Ikhoza kupirira dzimbiri za zidulo, alkalis ndi mankhwala ena, motero kuonetsetsa kulondola ndi kudalirika kwa zotsatira zoyesera.
4. Kutentha kwabwino kwambiri: The graphite crucible imakhala ndi matenthedwe abwino kwambiri ndipo imatha kutentha mofulumira komanso mofanana. Izi ndizofunikira kwambiri, makamaka poyesera zomwe zimafuna kutentha kapena kuziziritsa mwachangu, kuti muyese bwino komanso kuchepetsa nthawi yoyesera.
5. Valani kukana ndi kukana mphamvu: graphite crucible chuma ali mkulu kuvala kukana ndi kukana mphamvu, ndipo akhoza kupirira ntchito kwa nthawi yaitali ndi ntchito kuyesera pafupipafupi. Izi zimapangitsa graphite crucible kukhala chida chodalirika choyesera chomwe chingathe kukhalabe chokhazikika komanso chodalirika pansi pa zochitika zosiyanasiyana zoyesera.
6. Mafotokozedwe ndi makulidwe osiyanasiyana: zida za graphite crucible zimapereka mitundu yosiyana siyana ndi makulidwe azinthu kuti zikwaniritse zosowa zosiyanasiyana zoyesera. Kaya ndi labotale yaying'ono kapena ntchito yayikulu yamafakitale, mutha kupeza chitsulo choyenera cha graphite.
graphite crucible zakhala chida chofunikira kwambiri choyesera mu labotale ndi mafakitale chifukwa cha kukhazikika kwake kwa kutentha, kukhazikika kwamankhwala komanso kusinthasintha kwabwino kwamafuta. Ntchito zake zambiri zimaphatikizapo mafakitale ambiri, kuphatikiza chemistry, zitsulo, zamagetsi, zamankhwala ndi zina. Kaya amagwiritsidwa ntchito pochita kutentha kwambiri, kusungunuka kwa zitsanzo kapena zosowa zina zoyesera, zida za graphite crucible zingapereke ntchito yodalirika komanso malo oyesera okhazikika, kupereka chithandizo champhamvu pa kafukufuku wa sayansi ndi ndondomeko yogwiritsira ntchito.
