Embonini yanamuhla, izinto ezisebenza kahle, ezinobungani nemvelo, nezihlala isikhathi eside ziya ngokuya zithandwa. Izitsha zobumba ezincane ze-silicon carbide, njengezinto ezisebenza kahle kakhulu ezinezimbobo, zidlala indima ebalulekile emikhakheni efana nokuhlunga okushisa okuphezulu, ukuvikelwa kwemvelo, kanye nobunjiniyela bamakhemikhali obunembile ngenxa yezinzuzo zazo zokusebenza ezihlukile.
1. Iyini i-silicon carbide microporous ceramic?
I-silicon carbide (i-SiC)iyinhlanganisela eyakhiwe yi-silicon ne-carbon, enobulukhuni obuphezulu kakhulu, ukumelana nokushisa okuphezulu, kanye nokumelana nokugqwala, futhi yaziwa ngokuthi “idayimani yezimboni”. Izitsha zobumba ezincane ezinezimbobo ziyizinto ezigcwele izimbobo ezincane ngaphakathi, ezizinika izakhiwo ezinhle kakhulu zokuhlunga, ukumuncwa, kanye nokuphefumula.
I-silicon carbide microporous ceramics ihlanganisa izakhiwo ezinhle kakhulu ze-silicon carbide nezici zesakhiwo se-microporous, ezingagcina uzinzo ezindaweni ezimbi kakhulu futhi zifeze ukuhlungwa nokuhlukaniswa kwamagesi noma uketshezi okuphumelelayo, okwenza kube ithuluzi eliguquguqukayo emkhakheni wezimboni.
2. Kungani i-silicon carbide microporous ceramics ithandwa kakhulu?
1. Ukumelana nokushisa okuphezulu, okuzinzile njengedwala
Izinto eziningi zithambekele ekuguqukeni noma ekuhlulekeni emazingeni okushisa aphezulu, kuyilapho i-silicon carbide microporous ceramics ingasebenza kahle ezindaweni ezingaphezu kuka-1200 ℃ isikhathi eside ngaphandle kokuthinta ukusebenza kwayo ngenxa yokushisa okuphezulu. Lokhu kwenza kube ukukhetha okuhle kokwelashwa kwegesi yoketshezi olushisayo ezimbonini ezifana ne-metallurgy kanye namandla.
2. Ukuhlunga okunembile nokuhlukaniswa okusebenzayo
Ngokulawula ngokunembile usayizi wama-micropores, i-silicon carbide microporous ceramics ingavimba izinhlayiya ezincane ngisho nezinto ezisezingeni lama-molecule. Ekukhiqizweni kwamakhemikhali, ingahlukanisa ngempumelelo ama-catalyst; Emkhakheni wokuvikelwa kwemvelo, ingabamba uthuli oluyingozi kugesi kadoti wezimboni futhi isize ekukhiqizweni okuluhlaza.
3. Ihlala isikhathi eside futhi inciphisa izindleko zokulungisa
Izinto ze-silicon carbide ngokwazo zinamandla kakhulu okuguga kanye nokumelana nokushaqeka kokushisa. Ngisho nasezindaweni ezishisayo ezibandayo noma ezikhumulweni eziphakeme, i-silicon carbide microporous ceramics ingagcina ukuqina, inciphise kakhulu imvamisa yokushintsha imishini futhi yehlise izindleko zokusebenza kwebhizinisi.
3, izimo zokusetshenziswa kwe-silicon carbide microporous ceramics
Ukuhlanzwa kwegesi okushisa okuphezulu: njengokuncibilikisa insimbi, ukushiswa kukadoti, njll., kungabamba kahle izinhlayiya kugesi yomoya oshisayo okushisa okuphezulu futhi kubuyise amandla okushisa.
I-chemistry enembile kanye ne-catalysis: Njengesithwali se-catalyst, ithuthukisa ukusebenza kahle kokusabela futhi ingamelana nezimo ezinzima njenge-acids eqinile kanye nezisekelo.
Emkhakheni wamandla amasha, ukwesekwa kokusabalala kwegesi okuzinzile kunikezwa ezinqubweni ezifana nokulungiswa kwamandla e-hydrogen kanye nokushiswa kwezinto zebhethri.
Ukwelashwa kwamanzi ngokwemvelo: Ngokushintsha ubuso, ingasetshenziswa ekuhlanzweni kwamanzi angcolile anamafutha, ukumuncwa kwensimbi esindayo, njll., ukusiza ekukhiqizeni okuhlanzekile.
4, isiqondiso sentuthuko yesikhathi esizayo
Ngokuthuthuka kobuchwepheshe bezimboni kanye nesidingo esikhulayo sokuvikelwa kwemvelo, izitsha ze-silicon carbide ezincane ezinamaphiko ziyathuthuka ziye ekuqondeni nasekuhlakanipheni okuphezulu. Isibonelo, ukuthuthukisa ukusebenza kwayo ngobuchwepheshe bokumboza obuhlanganisiwe, noma ukuyihlanganisa nezinhlelo zokuqapha ezihlakaniphile ukuze kufezwe ukulawula kwesikhathi sangempela. Esikhathini esizayo, kulindeleke ukuthi ikhanye emikhakheni ephezulu njenge-semiconductors kanye ne-biomedicine.
isiphetho
Nakuba izitsha zobumba ezincane ze-silicon carbide zingase zibonakale zivamile, zidlala indima ebalulekile ekukhiqizweni kwezimboni nasekuvikelweni kwemvelo. Zivikela buthule ukuhlanzeka nokusebenza kahle komkhiqizo wezimboni ngokusebenza okuzinzile, amandla okuhlunga asebenzayo, kanye nokuqina okuhlala isikhathi eside. Esikhathini esizayo, ngokusungulwa kobuchwepheshe okuqhubekayo, zizoqhubeka nokufaka isandla ekuthuthukisweni kwezimboni kanye nentuthuko eluhlaza.
