Esithandweni sokushisa okuphezulu esiqhubeka nokusebenza endaweni yokusebenzela yensimbi, ingxenye ye-ceramic ibekezelela buthule ukushisa okushisayo; Esimisweni sokususa i-flue gas desulfurization, i-ceramic nozzle imelana nokuhlolwa kokugqwala kwe-asidi enamandla ne-alkali. 'Amaqhawe angadunyiswanga' kulezi zigcawu zezimboni yizinto ezimbili ze-ceramic ezithuthukisiwe esizozihlola namuhla -i-silicon carbidekanye ne-aluminium oxide.
1, Ukubhekana ngqo: Ngubani 'uMzimba weDayimane' wangempela?
Njenge-"izikhali" emkhakheni wezimboni, ubulukhuni bezinto zokwakha bunquma ngqo impilo yazo yokusebenza. Ubulukhuni be-silicon carbide ceramics bufana nobe-diamonds yemvelo, okubonisa ukukhuthazela okumangalisayo ngaphansi kwezimo zokungqubuzana okuqhubekayo. Njengokusika ingilazi ngedayimane, lapho i-alumina ceramics ibonisa imihuzuko emincane ngesikhathi sokuguguleka isikhathi eside, i-silicon carbide isagcina indawo ebushelelezi. Lesi sici sandisa impilo yayo yokusebenza isikhathi eside izikhathi eziningana kune-alumina ceramics ezimweni ezifana nama-valve epompo okuhambisa i-slurry nama-nozzles omshini wokulungisa ngokunemba.
2, 'INkosi Yokukhuthazela' Empini Yempi Ephakeme
Uma singena endaweni yokusebenzela yokwenziwa kwezinto zokwakha, igagasi lokushisa elinamandla lisikhumbuza ukuthi izinto zangempela ezimelana nokushisa okuphezulu ziyadingeka lapha. Izitsha zethu ze-silicon carbide zingagcina ukuqina kwesakhiwo ngisho naku-1350 ℃, zibonise ikhono lazo lokumelana nokushisa okukhulu. Izitsha ze-silicon carbide kulula ukuzenza futhi zihlala isikhathi eside, okwenza zibe ukukhetha okuthandwayo kwamasimu asezingeni eliphezulu njengokumelana nokushisa kuma-oven, ukwelashwa kokushisa kwensimbi, kanye nezisekelo zesitofu se-semiconductor single crystal.
3, 'Umqaphi Oyinhloko' ngaphansi Kokugqwala Kwamakhemikhali
Njengoba zibhekene "nemvula ene-asidi" ezitshalweni zamakhemikhali, izitsha ze-silicon carbide ezihlanzekile kakhulu zibonisa ukuzinza okumangalisayo, njengokufaka izingubo zokuzivikela ezingabonakali emishinini, noma ngabe zivezwe ezintweni ezimbi kakhulu njenge-sulfuric acid egxilile kanye ne-aluminium encibilikisiwe isikhathi eside, zisalokhu zinjalo. Kodwa-ke, izitsha ze-alumina zingase zizwe "ziqhekeka" ezindaweni ezithile ezifana ne-hydrofluoric acid, okwenza izitsha ze-silicon carbide ezihlanzekile kakhulu zibe khona okungenakuphikwa ezingxoxweni zamakhemikhali zokulwa nokugqwala, izitofu ze-lithium battery sintering, nakwezinye izimo.
4, Invisible Cost Revolution
Nakuba ukutshalwa kwezimali kokuqala ku-silicon carbide ceramics kuphakeme kancane, izinzuzo zesikhathi eside ezilethayo zidlula kakhulu ukucabanga. Amakhasimende ethu anciphise kakhulu imvamisa yawo yokugcinwa minyaka yonke ngemuva kokushintsha ipuleti le-lining elingagugi le-silicon carbide. Lesi sici "sokutshalwa kwezimali kanye, inzuzo yesikhathi eside" sishintsha isakhiwo sezindleko embonini yokukhiqiza.
Njengoba zimi endaweni yokuhlangana kokuthuthukiswa kwezimboni, ukukhethwa kwezinto sekuphenduka indawo yokuncintisana kwebhizinisi. I-silicon carbide ceramics, ngokuthuthuka kwayo kokusebenza okubanzi, ayichazi nje kuphela imingcele yokusetshenziswa kwe-ceramics yezimboni, kodwa futhi ikhuthaza ukuthuthuka kokukhiqiza okuya ekusebenzeni kahle okuphezulu kanye nokongiwa kwamandla. Lapho imishini yokukhiqiza idinga ukubhekana nezinselele eziqinile, lokhu "okuguquguqukayo" okuvela kwisayensi yezinto zanamuhla kunikeza amabhizinisi ezimboni izixazululo eziqondiswe esikhathini esizayo.
