Kwimizi-mveliso yanamhlanje, izinto ezisebenzayo, ezinobuhlobo nokusingqongileyo, nezihlala ixesha elide ziyaxatyiswa ngakumbi. Iiceramics ze-silicon carbide microporous, njengezinto ezinamachibi aphezulu, zidlala indima ebalulekileyo kwiindawo ezifana nokuhluza obushushu obuphezulu, ukhuseleko lokusingqongileyo, kunye nobunjineli beekhemikhali obuchanekileyo ngenxa yeenzuzo zazo zokusebenza ezizodwa.
1. Yintoni i-silicon carbide microporous ceramic?
I-silicon carbide (i-SiC)yi-compound eyenziwe yi-silicon kunye ne-carbon, enobunzima obuphezulu kakhulu, ukumelana nobushushu obuphezulu, kunye nokumelana nokugqwala, kwaye yaziwa ngokuba yi-"industrial diamond". Ii-micro-porous ceramics zizinto ezizaliswe zii-pores ezincinci ngaphakathi, ezizinika iipropati ezilungileyo zokuhluza, ukufunxa, kunye nokuphefumla.
Iiceramics ze-silicon carbide ezinemibhobho emincinci zidibanisa iipropati ezintle ze-silicon carbide kunye neempawu zesakhiwo esinemibhobho emincinci, ezinokugcina uzinzo kwiindawo ezixineneyo kwaye zifezekise ukuhluzwa kunye nokwahlulwa kweegesi okanye ulwelo ngokufanelekileyo, nto leyo ezenza zibe sisixhobo esisebenzisekayo kwicandelo lemizi-mveliso.
2, Kutheni iiceramics zesilicon carbide ezinemibhobho emincinci zithandwa kakhulu?
1. Ukumelana nobushushu obuphezulu, okuzinzileyo njengelitye
Izinto ezininzi zinokuguquguquka okanye zingasebenzi kakuhle xa kushushu kakhulu, ngelixa ii-silicon carbide microporous ceramics zinokusebenza ngokuzinzileyo kwiindawo ezingaphezulu kwe-1200 ℃ ixesha elide ngaphandle kokuchaphazela ukusebenza kwazo ngenxa yobushushu obuphezulu. Oku kwenza ukuba ibe lukhetho olufanelekileyo lonyango lwegesi yolwelo olushushu kakhulu kumashishini afana ne-metallurgy kunye namandla.
2. Ukucoca ngokuchanekileyo kunye nokwahlula ngokufanelekileyo
Ngokulawula ngokuchanekileyo ubungakanani bee-micropores, ii-silicon carbide microporous ceramics zinokubamba amasuntswana amancinci kwanezinto ezikwinqanaba le-molecular. Kwimveliso yeekhemikhali, inokwahlulahlula ngempumelelo ii-catalysts; Kwicandelo lokhuseleko lokusingqongileyo, inokubamba uthuli oluyingozi kwigesi yenkunkuma yemizi-mveliso kwaye incede kwimveliso eluhlaza.
3. Ihlala ixesha elide kwaye inciphisa iindleko zokugcina
Izinto ze-silicon carbide ngokwazo zinokumelana nokuguguleka okunamandla kakhulu kunye nokumelana nobushushu. Nokuba kwiindawo ezibandayo ezitshintshana rhoqo okanye kwiindawo ezinomkhenkce ophezulu, ii-silicon carbide microporous ceramics zinokugcina uzinzo, zinciphisa kakhulu ukuphindaphindwa kwezixhobo kwaye zinciphise iindleko zokusebenza kweshishini.
3, iimeko zokusetyenziswa kweeseramikhi zesilicon carbide ezineembobo ezincinci
Ukucocwa kwegesi kubushushu obuphezulu: njengokunyibilikisa isinyithi, ukutshisa inkunkuma, njl.njl., kunokubamba ngokufanelekileyo izinto ezincinci kwigesi yolwelo olushushu oluphezulu kwaye kubuyisele amandla obushushu.
Ikhemistri echanekileyo kunye ne-catalysis: Njenge-catalyst carrier, iphucula ukusebenza kakuhle kwempendulo kwaye inokumelana neendawo ezinzima ezifana nee-asidi ezinamandla kunye neziseko.
Kwicandelo lamandla amatsha, inkxaso yokusasazeka kwegesi ezinzileyo inikezelwa kwiinkqubo ezinje ngokulungiswa kwamandla e-hydrogen kunye nokucocwa kwezinto zebhetri.
Unyango lwamanzi olungqongileyo: Ngokusebenzisa utshintsho kumphezulu, ingasetyenziselwa unyango lwamanzi amdaka aneoyile, ukufunxwa kwesinyithi esinzima, njl.njl., ukunceda ekuveliseni okucocekileyo.
4, ulwalathiso lophuhliso lwexesha elizayo
Ngokuphucuka kwetekhnoloji yemizi-mveliso kunye nemfuno ekhulayo yokukhuselwa kwendalo, iiceramics ze-silicon carbide microporous ziyaphuhla zisiya kulungelelwano oluphezulu kunye nobukrelekrele. Umzekelo, ukuphucula ukusebenza kwayo ngetekhnoloji yokugquma edibeneyo, okanye ukuyidibanisa neenkqubo zokubeka esweni ezikrelekrele ukuze kufezekiswe ulawulo lwexesha langempela. Kwixesha elizayo, kulindeleke ukuba ikhanye kwiinkalo eziphezulu ezifana nee-semiconductors kunye ne-biomedicine.
isiphelo
Nangona iiceramics ze-silicon carbide ezineembobo ezincinci zinokubonakala ziqhelekile, zidlala indima ebalulekileyo kwimveliso yemizi-mveliso kunye nokukhuselwa kokusingqongileyo. Zikhusela ngokuzolileyo ucoceko kunye nokusebenza kakuhle kwemveliso yemizi-mveliso kunye nokusebenza okuzinzileyo, amandla okuhluza asebenzayo, kunye nokuqina okuhlala ixesha elide. Kwixesha elizayo, ngobuchule obuqhubekayo bobuchwepheshe, iya kuqhubeka negalelo ekuphuculweni kwemizi-mveliso kunye nophuhliso oluluhlaza.
