"Enkundleni yempi eshisa kakhulu" yemboni yesimanje, izinto zensimbi zendabuko zivame ukubhekana nezinselele ezifana nokuthambisa i-deformation, i-oxidation kanye nokugqwala. Futhi uhlobo olusha lwezinto ezibizwai-silicon carbide ceramicisiba ngumnakekeli oyinhloko wemishini eshisa kakhulu ngamakhono amakhulu amathathu “okumelana nezinga lokushisa eliphezulu, ukulwa nokuyaluza, nokudlulisa ukushisa okusheshayo”.
1. Ikhono leqiniso lokumelana namazinga okushisa aphezulu
I-silicon carbide ceramics ngokwemvelo inamandla okumelana namazinga okushisa aphezulu. Ama-athomu akhona axhunywe ngokuqinile ngamabhondi aqinile aqinile, njengenethiwekhi enezinhlangothi ezintathu elukwe kusuka ezindongeni zensimbi, engagcina ubuqotho besakhiwo ngisho nasezimweni zokushisa eziphezulu ezingu-1350 ℃. Lesi sici siyenza ikwazi kalula ukusebenza kwesikhathi eside izinga lokushisa eliphezulu izinto zensimbi ezingakwazi ukumelana nazo, okuyenza ibe ukukhetha okuhle kwezinkambu ezifana nolayini lwaseziko nokuvikela okushisayo kwemikhumbi-mkhathi.
2, 'Isivikelo' ngokumelene nokugqwala kwe-oxidative
Ngaphansi kwengcindezi ekabili yokushisa okuphezulu kanye nemithombo yezindaba ebolayo, izinto ezijwayelekile zivame ukuxebula ungqimba ngongqimba njengensimbi egqwalile. Ingaphezulu le-silicon carbide ceramics lingakha ungqimba oluqinile lokuvikela lwe-silicon dioxide, njengokuzimboza ngezembatho zempi ezingabonakali. Lesi sici "sokuziphilisa" siyenza ikwazi ukumelana ne-oxidation yezinga eliphezulu lokushisa ku-1350 ℃ futhi imelane nokuguguleka kusawoti oncibilikisiwe, i-asidi ne-alkali. Igcina isimo somqaphi sokuthi "akunampushana, akukho ukuchithwa" ezindaweni ezinokhahlo ezifana nezishisi zikadoti nama-reactors amakhemikhali.
3. 'I-courier' yokushisa
Ngokungafani nezici "ezishisayo nezinomswakama" ze-ceramics evamile, izitsha zobumba ze-silicon carbide zine-thermal conductivity efana nezinsimbi. Kufana nesiteshi esakhelwe ngaphakathi sokukhipha ukushisa, esingadlulisela ngokushesha ukushisa okunqwabelene ngaphakathi kwedivayisi kuya ngaphandle. Lesi sici esithi “akukho ukufihla ukushisa” sigwema ngempumelelo umonakalo odalwe amazinga okushisa asendaweni, okwenza okokusebenza kwezinga lokushisa eliphezulu kusebenze ngendlela ephephile futhi ewonga kakhudlwana amandla.
Kusukela eziko ezimbonini kuya ezithandweni ze-silicon wafer sintering ze-photovoltaic, kusukela kumashubhu emisebe amakhulu kuya kumabhobho ashisa kakhulu, izitsha zobumba ze-silicon carbide zilungisa kabusha isimo sezobuchwepheshe semboni yezinga lokushisa eliphezulu ngezinzuzo zazo eziphelele "zokuqina, ukuzinza, nokudluliswa okusheshayo". Njengomhlinzeki wesevisi yezobuchwepheshe ohileleke ngokujulile emkhakheni wezitsha zobumba ezithuthukisiwe, siyaqhubeka nokukhuthaza impumelelo kanye nokuqanjwa kokusebenza kwezinto ezibonakalayo, okuvumela okokusebenza kwezimboni okwengeziwe ukugcina isimo sokusebenza “esizolile nesihlanganisiwe” ezindaweni eziyingozi kakhulu.
——Seqa umkhawulo wokushisa wezinto zokwakha, sihamba nobuchwepheshe!
