Graphite carbon crucible

Chophimba cha carbon graphitendi chidebe chapadera chomwe chimagwiritsidwa ntchito m'malo otentha kwambiri kusungunula ndi kuponyera zitsulo, zoumba, ndi zinthu zina. Wopangidwa makamaka kuchokera ku graphite, amapereka matenthedwe apamwamba kwambiri, kusakhazikika kwamankhwala, komanso kukana kugwedezeka kwamafuta. Zinthu izi zimapangitsa kuti ma graphite crucible akhale abwino pantchito zosiyanasiyana zamafakitale, kuphatikiza kusungunula zitsulo zopanda chitsulo monga mkuwa, mkuwa, ndi aluminiyamu.

Crucible kukula

Zipangizo ndi Zomangamanga
Ma graphite crucibles amapangidwa ndi zinthu zingapo:

• Graphite (45-55%): Chigawo chapakati, chopereka kutentha kwabwino kwambiri komanso kukhazikika kwamafuta.
• Silicon carbide, silika, dongo: Zidazi zimakulitsa mphamvu zamakina a crucible komanso kukana dzimbiri, makamaka m'malo otentha kwambiri.
• Clay binder: Imatsimikizira kugwirizana koyenera kwa zipangizo, kupatsa crucible mawonekedwe ake ndi kukhulupirika kwapangidwe.

Kukula kwa tinthu tating'ono ta graphite komwe kumagwiritsidwa ntchito kumasiyananso kutengera kukula ndi cholinga cha crucible. Mwachitsanzo, ma crucibles akuluakulu amagwiritsa ntchito graphite yokulirapo, pomwe ma crucible ang'onoang'ono amafunikira graphite yowoneka bwino kuti ikhale yolondola komanso kuti igwire bwino ntchito.

Kugwiritsa ntchito Graphite Crucible
Ma graphite carbon crucibles amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana:

• Kuponyera zitsulo zopanda chitsulo: Zoyenera zitsulo monga mkuwa, golide, siliva, ndi mkuwa chifukwa cha kuchepa kwa mphamvu zawo zowonjezera kutentha.
• ng'anjo za induction: Nthawi zina, ma crucibles amapangidwa kuti azigwira ntchito ndi ng'anjo yapadera kuti azitha kuyendetsa bwino mphamvu komanso kutentha.
• Chemical processing: Kukhazikika kwawo kwamankhwala kumawapangitsa kukhala oyenera kugwiritsidwa ntchito m'malo omwe ali ndi zinthu za acidic kapena zamchere.

Malangizo Ofunika Kusamalira
Kuti muwonjezere moyo wa graphite carbon crucible, chisamaliro choyenera ndi kusunga ndikofunikira:

1. Kuziziritsa: Onetsetsani kuti crucible ikuzizira kwathunthu musanasungidwe kuti mupewe kugwedezeka kwa kutentha.
2. Kuyeretsa: Nthawi zonse chotsani zitsulo zotsalira ndi zotuluka pambuyo pa ntchito iliyonse kuti muteteze kuipitsidwa.
3. Kusungirako: Sungani crucible pamalo owuma, kutali ndi kutentha kwachindunji, kuti mupewe kuyamwa kwa chinyezi, zomwe zingayambitse kuwonongeka kwa mapangidwe.

Chifukwa Chiyani Tisankhire Zida Zathu?
Timapereka zapamwamba kwambirigraphite carbon crucibleszomwe zidapangidwa kuti zikwaniritse zosowa zosiyanasiyana zamafakitale. Ma crucibles athu amadzitamandira kukhazikika kwapamwamba, kukhathamiritsa kwamafuta, komanso moyo wautali, zomwe zimawapangitsa kukhala njira yotsika mtengo yopangira zitsulo zanu ndikusungunuka. Kaya mukugwiritsa ntchito ng'anjo yolowera m'ng'anjo kapena ng'anjo zachikhalidwe zoyatsira mafuta, ma crucible athu amapangidwa kuti akwaniritse bwino njira zanu zopangira.

Mafunso Ofunsidwa Kawirikawiri (FAQ)

1. Kodi graphite crucible imatha nthawi yayitali bwanji?
   Kutalika kwa moyo kumasiyanasiyana kutengera kagwiritsidwe ntchito, koma posamalira moyenera, ma graphite crucibles amatha kusungunuka nthawi zambiri, makamaka popanga zitsulo zopanda chitsulo.
2. Kodi ma graphite crucibles angagwiritsidwe ntchito pamitundu yonse ya ng'anjo?
   Ngakhale zimasinthasintha, zinthu zopangira crucible ziyenera kufanana ndi mtundu wa ng'anjo. Mwachitsanzo, ma crucible opangira ng'anjo yolowera amafunikira mphamvu yapadera yamagetsi kuti asatenthedwe.
3. Kodi graphite crucible imatha kupirira kutentha kotani?
   Nthawi zambiri, ma graphite crucibles amatha kutentha kuyambira 400 ° C mpaka 1700 ° C, kutengera kapangidwe kazinthu ndi ntchito.
