Kwimveliso yemizi-mveliso yanamhlanje, iinkqubo zemibhobho zifana “nemithambo yegazi” yomzimba womntu, zenza umsebenzi obalulekileyo wokuthutha izinto ezishushu kakhulu nezirhabaxa.umgca we-silicon carbide (SiC)Iteknoloji ifana nokubeka umaleko wezixhobo zokuzikhusela ezisebenzayo kakhulu kwezi “mithambo yegazi”, nto leyo enika umbhobho amandla okucinezelwa, ukumelana nokugqwala, kunye nokumelana nobushushu obuphezulu. Olu maleko lubonakala lulula lokukhusela lukhusela njani ukusebenza okuzinzileyo kwemibhobho?
1, iipropati zezinto ezibonakalayo: "Italente yendalo" ye-silicon carbide
I-silicon carbide yaziwa ngokuba yi-"industrial black diamond", kwaye isakhiwo sayo se-athomu yi-three-dimensional network crystal eyenziwe ngamabhondi e-covalent phakathi kwe-silicon kunye ne-carbon, eyinika iipropati ezintathu ezibalulekileyo:
1. Ubunzima bedayimani (bulandela idayimani kuphela kubunzima beMohs), obunokumelana nokukhukuliseka kwamasuntswana
2. Ukungasebenzi kakuhle kweekhemikhali, ukumelana neendaba ezirhabaxa ezifana nee-asidi, iziseko kunye neetyuwa
3. Uzinzo oluhle kakhulu lobushushu, olugcina uzinzo lolwakhiwo nokuba kumaqondo obushushu aphezulu angama-1350 ℃
Le propati yezinto ezibonakalayo yenza ukuba ibe yinto efanelekileyo yokukhusela kwiimeko ezinzima zokusebenza.
2, Indlela yoKhuselo: Inkqubo yoKhuselo kathathu
Xa i-silicon carbide lining inamathela eludongeni lwangaphakathi lombhobho, yenza iileya ezininzi zokhuseleko:
Umaleko womqobo obonakalayo: iikristale ze-silicon carbide ezixineneyo ziyawahlula ngokuthe ngqo amandla ombane ekudibaneni nomzimba wetyhubhu yesinyithi
Umaleko ozinzileyo wekhemikhali: ukwenza ifilimu ye-oxide ekhuselayo ngokusebenzisa i-passivation reaction, echasa ngokukhukulisa
Le ndlela yokukhusela edibeneyo ivumela imibhobho ukuba igcine ulwakhiwo lwayo lusemgangathweni naphantsi kweemeko ezinzima ezifana nokugqwala okunamandla, ukuguguleka okuphezulu, kunye neendawo ezinobushushu obuphezulu.
3, Imfihlo yokusebenza ixesha elide: amandla okuziphilisa
Uphando lwamva nje lufumanise ukuba i-silicon carbide inamandla okwahlulahlula umphezulu phantsi kweemeko ezithile zokusebenza. Xa kwenzeka umonakalo ngemicroscope, ii-athomu ze-silicon zasimahla kumphezulu wezinto ziya kuphinda zilungelelaniswe kwindawo enobushushu obuphezulu, zilungise iziphene zomphezulu kancinci. Olu phawu lwandisa kakhulu ubomi benkonzo ye-lining kwaye lunciphisa amaxesha okugcinwa.
4, Iingenelo ezingabonakaliyo: ixabiso elipheleleyo lomjikelo wobomi
Xa kuthelekiswa nezinto zelineni zemveli, i-silicon carbide lining izisa iingenelo zoqoqosho ezifihlakeleyo kodwa ezinkulu kumashishini emizi-mveliso ngokunciphisa inani lokuvalwa kokugcinwa, ukunciphisa umngcipheko wongcoliseko oluphakathi, kunye nokwandisa umjikelo wokutshintshwa kwemibhobho. Ingakumbi kwimimandla yeekhemikhali ezincinci kunye nokulungiswa kwezinto ezintsha zamandla, ixabiso lokuqinisekiswa kobunyulu bezinto kunzima ngakumbi ukulilinganisa ngedatha elula.
Ngophuhliso lwetekhnoloji yemizi-mveliso olujolise ekusebenzeni kakuhle ngakumbi kunye nobuhlobo nokusingqongileyo, itekhnoloji ye-silicon carbide lining iyatshintsha ukusuka "kukhuseleko olukhethekileyo" ukuya "kwisimo esiqhelekileyo". Esi sisombululo esidibanisa isayensi yezinto eziphathekayo kunye nobukrelekrele bobunjineli sikhusela buthule "umgca wobomi" wemizi-mveliso yanamhlanje kwaye siba yinkxaso ebalulekileyo yobugcisa ekuphuculeni umgangatho kunye nokusebenza kakuhle kwamashishini enkqubo.
