I-Graphite Crucibles

I-Graphite Crucibleszinikeza ububanzi bezakhiwo ezizenza zibe yinketho ephezulu yezinhlelo zokusebenza ezishisa kakhulu, ikakhulukazi emsebenzini wokuncibilikisa insimbi nomsebenzi wokusungula. Nazi izici ezibalulekile zempahla kanye nokucaciswa okuchaza ukusebenza kwalezi zinsimbi:

1. I-Thermal Conductivity
   • I-graphite cruciblesbonisa ukusebenza kahle kwe-thermal, eqinisekisa ukusatshalaliswa kokushisa okufanayo. Le ndawo inciphisa izindawo ezishisayo futhi iqinisekisa ngisho nokuncibilika, izenze zisebenze kahle kakhulu ezinsimbi njengegolide, ithusi, ne-aluminium.
   • I-Thermal conductivity ingafinyelela kumanani afika ku-100 W/m·K, ephakeme kakhulu uma kuqhathaniswa nezinto ezivamile zokuphikisa.
2. Ukumelana Nokushisa Okuphezulu
   • I-graphite cruciblesziyakwazi ukumelana namazinga okushisa aphakeme kakhulu, afinyelela ku-1700°Cemkhathini ongenayo noma izimo ze-vacuum. Lokhu kuzivumela ukuthi zigcine ubuqotho besakhiwo ezindaweni ezifunayo ngaphandle kokwehlisa isithunzi.
   • Lawa ma-crucibles ahlala azinzile futhi amelana nokuguqulwa ngaphansi kokushisa okukhulu.
3. I-Coefficient Ephansi Yokunweba Okushisayo
   • Izinto ze-graphite zine-ai-coefficient ephansi yokwandisa okushisayo(ephansi njenge-4.9 x 10^-6 /°C), inciphisa ingozi yokuqhekeka noma ukushaqeka okushisayo lapho kuvezwa izinguquko ezisheshayo zezinga lokushisa.
   • Lesi sici senza ama-graphite crucibles afaneleke ikakhulukazi izinqubo ezibandakanya imijikelezo yokushisisa nokupholisa ephindaphindiwe.
4. Ukumelana Nokugqwala
   • I-graphite ayisebenzi ngamakhemikhali futhi inikezwaukumelana okuphezulu kuma-acids amaningi, ama-alkali, namanye ama-ejenti ezonakalisayo, ikakhulukazi ekunciphiseni noma ekungathathi hlangothi emkhathini. Lokhu kwenza ama-graphite crucibles afaneleke endaweni yamakhemikhali anolaka ekubunjweni kwensimbi noma ekucwengisiseni.
   • Ukumelana ne-oxidation yezinto ezibonakalayo kungathuthukiswa ngokwengeziwe ngezingubo zokumboza noma ukwelashwa okukhethekile, ukuqinisekisa impilo yesevisi ende.
5. I-Electric Conductivity
   • Njengomqhubi omuhle kagesi, izinto ze-graphite zifanele izicelo zokushisa zokungeniswa. I-conductivity ephezulu kagesi yenza ukuhlanganisa okuphumelelayo nezinhlelo zokungeniswa, ukuqinisekisa ukushisa okusheshayo nokufana okufanayo.
   • Lesi sakhiwo siwusizo ikakhulukazi ezinqubweni ezidingayoI-induction heater crucibles, ethuthukisa ukusebenza kahle ezimbonini ezifana ne-Foundry work noma i-metallurgy.
6. Ubumsulwa Nokubunjwa Kwezinto
   • I-high-purity carbon graphite crucibles(kufika ku-99.9% ubumsulwa) bubalulekile ekusetshenzisweni lapho ukungcola kwensimbi kufanele kugwenywe, njengalapho kukhiqizwa izinsimbi eziyigugu noma izitsha zobumba ezithuthukisiwe.
   • I-silicon carbide graphite crucibleshlanganisa izakhiwo zakho zombili i-graphite ne-silicon carbide, enikeza amandla athuthukisiwe emishini, ukumelana ne-oxidation, nendawo ephakeme yokuncibilika, elungele izimo zokusebenza ezimbi kakhulu.
7. Ukuqina Nokuphila Isikhathi Eside
   • Ama-graphite crucibles acindezelwe ngokwe-Isostaticakhiwe ukuze abe nokuminyana okufanayo namandla, okuholela ekuphileni okude kanye nokuncipha kokuhluleka kwezinto ngesikhathi sokusebenza kwezinga lokushisa eliphezulu. Lawa ma-crucibles ayakwazi ukumelana nokuguguleka komhlabathi kanye nokulimala kwemishini.

8. Ukwakhiwa Kwekhemikhali:

   • Ikhabhoni (C): 20-30%
   • I-Silicon Carbide (SiC): 50-60%
   • I-Alumina (Al2o3): 3-5%
   • Abanye: 3-5%
9. Osayizi Nezimo ezenziwe ngokwezifiso
   • Ama-graphite ethu ama-brucible atholakala ezinhlobonhlobo zosayizi nokucushwa okuningi. Kusukaama-graphite crucibles amancane(ifanele ukuhlolwa kwensimbi kwesikali selebhu) ezitsheni ezinkulu ezidizayinelwe ukuncibilikiswa kwesikali sezimboni, sinikeza izixazululo ezihambisanayo kulo lonke uhlelo lokusebenza.
   • Ama-crucibles ane-graphitekanye crucibles ngeuthele ama-spoutsFuthi ingadalelwa kwizidingo ezithile zokusakaza, iqinisekisa ukusebenziseka kalula kanye nokusebenza kahle ekuphatheni ngensimbi.
