Kugwiritsa ntchito ndi makhalidwe a graphite sagger crucible

Crucible ingagwiritsidwe ntchito potenthetsera makhiristo ambiri mwamphamvu. Crucible ingagawidwe m'magulu awirichophikira cha graphitendichophikira cha quartz. Chophimba cha grafiti chili ndi kutentha kwabwino komanso kukana kutentha kwambiri; Pakugwiritsa ntchito kutentha kwambiri, kuchuluka kwa kutentha komwe kumawonjezeka ndi kochepa kwambiri. Chimalimbana ndi kutentha kwambiri komanso kuzizira kwambiri. Chimalimbana ndi asidi wamphamvu ndi alkali. Ndi choyenera kutentha mitundu yosiyanasiyana ya zakumwa; Kuphatikiza pa chemistry, zophimba za grafiti zimagwiritsidwa ntchito kwambiri mu metallurgy, casting, makina, makampani a mankhwala ndi madipatimenti ena; Chophimba cha grafiti chimapangidwa ndi zinthu zachilengedwe za graphite, zomwe zimasunga kutentha kwapadera kwapadera kwa graphite. Chophimba cha grafiti chimagwiritsidwa ntchito makamaka posungunula zitsulo zopanda chitsulo monga mkuwa, aluminiyamu ndi alloy. Pali zinthu zambiri za chophimba cha grafiti chokha. Pano tilemba mwachidule chimodzi kapena ziwiri zanu.
1. Kuchepetsa kuipitsa mpweya, chifukwa mphamvu zoyera monga gasi wachilengedwe kapena mpweya wosungunuka zingagwiritsidwe ntchito ngati mafuta komanso kuchepetsa kuipitsa mpweya.
2. Kugwiritsa ntchito mphamvu zochepa, chifukwa chophikira cha graphite chili ndi mapulani oyenera, kapangidwe kapamwamba komanso zipangizo zatsopano. Pambuyo poyesa, kugwiritsa ntchito mphamvu kumakhala kotsika kuposa kwa ng'anjo yamtundu womwewo.
Chotsukira cha graphite chotsukira kwambiri chimagwiritsidwa ntchito makamaka posungunula golide, siliva ndi zitsulo zosowa.Zophimba zadothiamagwiritsidwa ntchito kwambiri m'ma laboratories ndi kusungunula platinamu, golide ndi zitsulo zosowa. Kodi chofufumitsa cha graphite chingagwire ntchito pa kutentha kwakukulu kwa 2000 ℃ pansi pa mpweya? Kodi chidzawola ndi kusungunuka mwamphamvu? Kodi chidzasungunula chitsulo chosungunuka? Chofunika kwambiri ndichakuti kusungunuka kwa carburizing kumapha. Nthawi zonse, kumatha kufika madigiri 2000 mumlengalenga, koma kudzasungunuka mwachangu. Vuto la kusungunuka kwa carburizing liyenera kukhalapo. Tsopano pali utoto wapadera wotsutsana ndi carburizing pamsika, womwe umanenedwa kuti uli ndi zotsatira zabwino.
