I-Sic Crucibles

Izici

I-Sic Crucibles, ngokuyinhloko eyenziwe nge-silicon carbide, isetshenziswa kakhulu ezimbonini lapho izinga lokushisa eliphezulu nokumelana namakhemikhali kubalulekile. Lawa ma-crucibles abe yiwona ahamba phambili ekukhetheni izisekelo namalabhorethri ngenxa yokuqina kwawo okuphakeme, okuwenza abaluleke kakhulu ezinqubweni ezinjengokuncibilika kwensimbi, ukubunjwa, nokucwengisiswa.

Isingeniso ku-Sic Crucibles

Izakhiwo zenyama nezamakhemikhali zeI-Sic Crucibles

Lapho ukhetha ama-tucibles wezicelo zezimboni, ukuqonda izinkomba zomzimba nezamakhemikhali zibalulekile. Ngezansi kungukuwohloka kwezindawo ezibalulekile ze-ISO Type SIC Crucibles:

Izakhiwo Zomzimba Inkomba
I-Refractoriness ≥ 1650°C
I-Porosity ebonakalayo ≤ 20%
Ukuminyana kwenqwaba ≥ 2.2 g/cm²
Amandla Ahlabayo ≥ 8.5 MPa
Ukwakheka Kwamakhemikhali Inkomba
Okuqukethwe Kwekhabhoni (C%) 20–30%
I-Silicon Carbide (SiC%) 50-60%
I-Alumina (AL2O3%) 3–5%

Lezi zici zinikeza i-Sic Crucibles i-thermal conductivity ehlukile, ukunwebeka okuphansi kokushisa, nokumelana nokugqwala kwamakhemikhali, okuqinisekisa ukuthi isebenza kahle ngisho nasezimweni ezinzima kakhulu.

Izinzuzo ze-Sic Crucibles

  1. Ukumelana Nokushisa Okuphezulu: Ama-Sic Crucibles amelana nezinga lokushisa afika ku-1650°C, okuwenza alungele ukuncibilika kwensimbi nezinye izinhlelo zokusebenza ezishisa kakhulu.
  2. Ukuqina Nokuphila Isikhathi Eside: Ngamandla okuchoboza aqinile we-≥ 8.5 MPa, lezi ziphambano zingabekezelela izingcindezi zemishini ezihilelekile kuzilungiselelo zezimboni ngaphandle kokuqhekeka noma ukonakala.
  3. Ukuzinza Kwamakhemikhali: Okuqukethwe kwe-carbide ephezulu ye-silicon (50-60%) kunikeza ukumelana okuhle kakhulu ekuphendukeni kwamakhemikhali, ukuqinisekisa isikhathi eside noma kuvezwa izinsimbi ezibunjiweyo noma amakhemikhali anolaka.

Ukuphathwa Ngokuphephile Nokunakekelwa Kwe-Sic Crucibles

Ukuze unwebe isikhathi sempilo yama-Sic Crucibles futhi uqinisekise ukusebenza kwawo okuphephile, kubalulekile ukulandela imihlahlandlela embalwa yokunakekela:

  • Ukuhlanza Okuvamile: Ama-crucibles kufanele ahlanzwe njalo ukuze asuse noma yiziphi izinsalela, ukuvimbela ukungcola nokugqwala.
  • Gwema Ukwethuka Okushisayo: Ukushisa kancane kancane kanye nokupholisa kubalulekile ukuvimbela ukuqhekeka. Ukushintsha okungazelelwe kwezinga lokushisa kungabangela ukuba impahla iphuke.
  • Vimbela ukugqwala kwamakhemikhali: Gwema ukuchayeka kumakhemikhali alimazayo, ikakhulukazi izixazululo ezine-alkaline noma ezine-asidi, ezingehlisa isithunzi sesakhiwo se-crucible.

Ulwazi olusebenzayo lwabathengi

Ukukhetha i-Sic Crucible efanele kuncike ezidingweni ezithile zenqubo yakho yezimboni. Cabangela izici ezifana nezinga lokushisa, ukuhambisana kwezinto ezibonakalayo, nezidingo zosayizi. Kuzinhlelo zokusebenza zomhlaba wangempela, abathengi abaningi babike ukwehliswa okukhulu kwezindleko zokunakekela kanye nokwandisa ukusebenza kahle kokukhiqiza ngokushintshela ku-Sic Crucibles.

I-Sic Crucibles iyithuluzi elibalulekile lezimboni ezifuna izinto ezisebenza kahle ezikwazi ukumelana namazinga okushisa adlulele kanye nokuchayeka kumakhemikhali. Ngokuqonda izakhiwo zabo nokulandela izimiso ezifanele zokunakekela, amabhizinisi angathuthukisa ukusebenza kahle ngenkathi ehlisa isikhathi sokungasebenzi.
