Embonini yesimanje, izinto zokwakha ezisebenzayo, ezinobungani kwemvelo, nezihlala isikhathi eside ziya ngokuya ziba yigugu. I-silicon carbide microporous ceramics, njengento esebenza kahle kakhulu enezimbotshana, idlala indima ebalulekile emikhakheni efana nokuhlunga kwezinga lokushisa eliphezulu, ukuvikelwa kwemvelo, nobunjiniyela bamakhemikhali obunembayo ngenxa yezinzuzo zabo zokusebenza ezihlukile.
1. Yini i-silicon carbide microporous ceramic?
I-Silicon carbide (SiC)iyinhlanganisela eyakhiwe nge-silicon ne-carbon, enobulukhuni obuphezulu kakhulu, ukumelana nokushisa okuphezulu, nokumelana nokugqwala, futhi yaziwa ngokuthi "idayimane lezimboni". I-Micro porous ceramics yizinto ezigcwele izimbotshana ezincane ngaphakathi, ezizinikeza ukuhlunga okuhle kakhulu, ukukhangiswa, kanye nezakhiwo zokuphefumula.
I-silicon carbide microporous ceramics ihlanganisa izakhiwo ezinhle kakhulu ze-silicon carbide nezici zesakhiwo se-microporous, esingagcina uzinzo ezindaweni ezibucayi futhi sifinyelele ukuhlungwa okuphumelelayo nokuhlukaniswa kwamagesi noma uketshezi, okubenza babe yithuluzi eliguquguqukayo emkhakheni wezimboni.
2. Kungani i-silicon carbide microporous ceramics ithandwa?
1. Ukumelana nokushisa okuphezulu, kuzinzile njengetshe
Izinto eziningi zijwayele ukuwohloka noma ukwehluleka emazingeni okushisa aphezulu, kuyilapho i-silicon carbide microporous ceramics ingasebenza ngokuzinza endaweni engaphezu kuka-1200 ℃ isikhathi eside ngaphandle kokuthikameze ukusebenza kwayo ngenxa yamazinga okushisa aphezulu. Lokhu kuyenza ibe inketho efanelekile yokwelashwa kwegesi yokushisa ephezulu ezimbonini ezifana ne-metallurgy namandla.
2. Ukuhlunga okunembile kanye nokwehlukanisa okuphumelelayo
Ngokulawula ngokunembile usayizi wama-micropores, i-silicon carbide microporous ceramics inganqanda izinhlayiya ezincane ngisho nezinto ezisezingeni lamangqamuzana. Ekukhiqizeni amakhemikhali, ingakwazi ukuhlukanisa ngempumelelo ama-catalysts; Emkhakheni wokuvikelwa kwemvelo, ingabamba uthuli oluyingozi kugesi odoti wezimboni futhi isize ekukhiqizeni okuluhlaza.
3. Ihlala isikhathi eside futhi inciphisa izindleko zokunakekela
I-silicon carbide impahla ngokwayo inokumelana nokugqoka okunamandla kakhulu kanye nokumelana nokushaqeka okushisayo. Ngisho nasezindaweni ezishintshashintshayo ezishisayo ezibandayo noma ezindaweni eziguguleka kakhulu, izitsha ze-silicon carbide microporous ceramics zingagcina uzinzo, zehlise kakhulu imvamisa yokushintshwa kwemishini futhi zehlise izindleko zokusebenza zebhizinisi.
3. Izimo zokusetshenziswa kwe-silicon carbide microporous ceramics
Izinga lokushisa eliphezulu lokuhlanzwa kwegesi: njengokuncibilika kwensimbi, ukushiswa kukadoti, njll., kungathatha ngempumelelo i-particle kugesi eshisa kakhulu futhi ibuyise amandla okushisa.
Amakhemikhali anembe kanye ne-catalysis: Njengesithwali se-catalyst, ithuthukisa ukusebenza kahle kokusabela futhi ingamelana nezindawo ezinokhahlo njengama-asidi aqinile nezisekelo.
Emkhakheni wamandla amasha, ukusekela kokusabalalisa kwegesi okuzinzile kunikezwa ngezinqubo ezifana nokulungiswa kwamandla e-hydrogen kanye nokucwiliswa kwebhethri.
Ukwelashwa kwamanzi emvelo: Ngokulungiswa kwendawo, angasetshenziswa ukwelapha amanzi angcolile anamafutha, i-adsorption yensimbi enzima, njll., ukusiza ekukhiqizeni okuhlanzekile.
4. Isiqondiso sokuthuthukiswa kwekusasa
Ngokuthuthuka kobuchwepheshe bezimboni kanye nesidingo esikhulayo sokuvikelwa kwemvelo, i-silicon carbide microporous ceramics ithuthukela ekunembeni nasekuhlakanipheni okuphezulu. Isibonelo, ukuthuthukisa ukusebenza kwayo ngobuchwepheshe bokuhlanganisa okuyinhlanganisela, noma ukuyihlanganisa nezinhlelo zokuqapha ezihlakaniphile ukuze kuzuzwe ukulawula kwesikhathi sangempela. Ngokuzayo, kulindeleke ukuthi kukhanye emikhakheni esezingeni eliphezulu njengama-semiconductors kanye ne-biomedicine.
isiphetho
Nakuba i-silicon carbide microporous ceramics ingase ibonakale ijwayelekile, idlala indima ebalulekile ekukhiqizweni kwezimboni nokuvikelwa kwemvelo. Ivikela buthule ukuhlanzeka nokusebenza kahle kokukhiqizwa kwezimboni ngokusebenza okuzinzile, umthamo wokuhlunga ophumelelayo, nokuqina okuhlala isikhathi eside. Ngokuzayo, ngokusungulwa okuqhubekayo kobuchwepheshe, izoqhubeka nokufaka isandla ekuthuthukisweni kwezimboni nasekuthuthukisweni kokuluhlaza.
