Ha ho tluoa tabeng ea "ceramics", batho ba bangata ba qala ho nahana ka lijana tsa ntlo, li-vases tse khabisitsoeng - tse fokolang le tse bonolo, tse bonahalang eka ha li amane le "indasteri" kapa "hardcore". Empa ho na le mofuta oa ceramic o senyang maikutlo ana a tlhaho. Boima ba eona ke ba bobeli feela ho daemane, 'me e khona ho mamella mocheso o phahameng, ho hanela kutu, hape e be insulated le conductive, e fetoha "mofuta o fapaneng" lefapheng la indasteri. Ho joalosilicon carbide ceramic.
Ho tloha ho thepa e sa sebetseng merafong ho ea ho li-module tsa motlakase likoloing tse ncha tsa matla, ho tloha likarolong tse phahameng tsa mocheso sebakeng sa sefofane ho ea ho li-seal tsa mechine ea letsatsi le letsatsi, li-ceramics tsa silicon carbide li tšehetsa ka khutso ts'ebetso e sebetsang ea liindasteri tse ngata ka thepa ea tsona e ikhethang. Kajeno, a re ke re bue ka hore na ke eng e etsang hore ceramic e "sa tloaelehang" e hlahelle.
1, Ho thata ho feta tekano: "mojari" tšimong ea ho hanyetsa ho apara
Monyetla o tsebahalang ka ho fetesisa oa li-ceramics tsa silicon carbide ke boima ba eona bo phahameng haholo le ho hanyetsa ho roala. Boima ba eona ba Mohs ke ba bobeli ho feta taemane e thata ka ho fetisisa tlhahong, e thata haholo ho feta tšepe e tloaelehileng, tšepe e sa hloekang, esita le lirafshoa tsa alumina.
Sebopeho sena sa 'hardcore' se etsa hore e khanye maemong ao e hlokang ho hanela ho khathala le ho taboha. Ka mohlala, indastering ea merafo le ea metallurgical, lisebelisoa tsa ho tsamaisa slurry le slag slurry (joalo ka li-impellers tsa lipompo tsa slurry le li-pipeline liners) hangata li hlatsuoa ke likaroloana tse thata tsa liminerale ka nako e telele, 'me litšepe tse tloaelehileng li tla senyeha kapele ebe metsi a lutla. Likarolo tse entsoeng ka li-ceramics tsa silicon carbide li ka mamella "abrasion" ena habonolo mme li na le bophelo ba ts'ebeletso ka makhetlo a 'maloa kapa ho feta makhetlo a leshome a likarolo tsa tšepe, ho fokotsa haholo makhetlo le litšenyehelo tsa ho nkela thepa sebaka.
Eseng feela maemong a indasteri, re ka boela ra bona boteng ba eona bophelong ba letsatsi le letsatsi - joalo ka silicon carbide friction pair ho litiiso tsa mochini. Ka ho hanyetsa ha eona ho khabane ka ho fetisisa, e etsa bonnete ba hore lisebelisoa ha li fokotsehe 'me li na le tahlehelo e fokolang nakong ea ho potoloha ka lebelo le phahameng, ho lumella ho sebetsa ka mokhoa o tsitsitseng oa lisebelisoa tse kang lipompo tsa metsi le li-compressor.
2, "Khanyetso" e Phahameng: Insulation bakeng sa Mocheso o Phahameng le Corrosion
Ntle le ho thatafala, li-ceramics tsa silicon carbide li boetse li na le ho hanyetsa mocheso o phahameng haholo le ho hanyetsa kutu, e leng se ba lumellang hore ba "khomarele lits'ebetsong tsa bona" libakeng tse ngata tse thata.
Mabapi le ho hanyetsa mocheso o phahameng, esita le ka mor'a ts'ebetso ea nako e telele ho 1350 ℃, ho ke ke ha e-ba le ho nolofatsa kapa ho senyeha. Tšobotsi ena e etsa hore e be "moratuoa" liindastering tsa lifofane le tsa sesole, tse kang ho sebelisoa e le nozzle bakeng sa lienjineri tsa rocket, lesela la libopi tsa mocheso o phahameng, joalo-joalo E ka kopana ka ho toba le malakabe a mocheso o phahameng kapa tšepe e qhibilihisitsoeng ho boloka botsitso. Lits'ebetsong tsa tlhahiso ea mocheso o phahameng joalo ka li-kilns tsa indasteri le metallurgical casting e tsoelang pele, silicon carbide ceramic components le tsona li ka nkela litšepe tse senyehang habonolo ke mocheso o phahameng, ho lelefatsa bophelo ba lisebelisoa.
Mabapi le ho hanyetsa kutu, li-ceramics tsa silicon carbide li na le botsitso bo matla haholo ba lik'hemik'hale. Ebang ke asiti, alkali, kapa likhase tse sa tšoaneng tse senyang le lintho tse metsi, ho thata ho e “khohola”. Ka hona, indastering ea lik'hemik'hale, hangata e sebelisoa ho etsa lesela la likepe tse arabelang, liphaephe le li-valve bakeng sa ho tsamaisa mecha ea litaba e senyang; Sebakeng sa ts'ireletso ea tikoloho, boteng ba eona bo ka boela ba bonoa lisebelisoa tsa ho phekola metsi a litšila a nang le acid-base e phahameng, ho etsa bonnete ba hore lisebelisoa ha li senyehe ebile li sebetsa ka mokhoa o tsitsitseng.
3, "Bokhoni" bo feto-fetohang: "Monghali ea sebetsang" ea ka thata le ho tenyetseha
Haeba u nahana hore li-ceramics tsa silicon carbide li "thata" feela 'me "li tšoarella", joale u li khella fatše haholo. Ho latela mekhoa e fapaneng ea ts'ebetso, e ka ba le mesebetsi e mengata joalo ka conductivity, insulation, le conductivity ea mocheso, e etsa hore e be sesebelisoa se sebetsang se nang le ts'ebeliso e mengata.
-Conductivity le thepa ea semiconductor: Ka ho sebelisa doping le likarolo tse ling, li-ceramics tsa silicon carbide li ka fetoha ho tloha ho li-insulators ho ea ho li-conductor, esita le ho fetoha lisebelisoa tsa semiconductor. Sena se e lumella ho bonts'a litsebo tsa eona lefapheng la matla a elektronike, joalo ka ho etsa li-module tsa matla bakeng sa likoloi tse ncha tsa matla le likarolo tsa mantlha bakeng sa li-converter tsa traction ka literene tse lebelo. Ha ho bapisoa le lisebelisoa tsa silicon tse tloaelehileng, li-semiconductors tsa silicon carbide li na le ts'ebetso e phahameng ea conductivity le tšebeliso e tlaase ea matla, e ka etsang hore likoloi tse ncha tsa matla li lefelle ka potlako 'me li be le nako e telele, hape li etsa hore thepa ea matla e be nyenyane le e sebetsang haholoanyane.
-Excellent thermal conductivity: Thermal conductivity ea silicon carbide ceramics e feta hōle ea ceramics e tloaelehileng, esita le ho atamela ea tšepe e itseng. Tšobotsi ena e etsa hore e be thepa e loketseng ea ho senya mocheso, mohlala, karolong e ka tlaase ea mocheso ea mabone a LED le lisebelisoa tsa elektronike, e ka tsamaisa mocheso ka potlako, ea thibela lisebelisoa hore li se ke tsa senyeha ka lebaka la ho chesa haholo, le ho ntlafatsa bophelo ba tšebeletso le botsitso.
4, Qetellong: Li-ceramics tsa silicon carbide, 'matla a sa bonahaleng a ho khanna' a ntlafatso ea indasteri
Ho tloha "ho thata le ho se mamelle" ho ea ho "ho hanyetsa mocheso o phahameng oa mocheso", 'me joale ho ea ho "multifunctionality", li-ceramics tsa silicon carbide li robehile kutloisiso ea batho ea li-ceramics tsa setso tse nang le letoto la thepa e babatsehang, e leng ntho e ka sehloohong e tšehetsang tsoelo-pele ea lihlahisoa tse phahameng, matla a macha, ho boloka matla le ho sireletsa tikoloho. Ha e tloaelehe joaloka tšepe kapa e bobebe joaloka polasetiki, empa maemong a indasteri a hlokang "ho hlōla mathata", e lula e itšetlehile ka litšobotsi tsa eona tsa "matla" hore e be matla a mantlha a ho rarolla mathata.
Ka tsoelo-pele e tsoelang pele ea theknoloji, theko ea tlhahiso ea silicon carbide ceramics e ntse e fokotseha butle-butle, 'me maemo a ts'ebeliso le ona a ntse a eketseha kamehla. Nakong e tlang, lisebelisoa tse ncha tse sebetsang hantle haholoanyane le mechini e tšoarellang ea indasteri li ka ba matla le ho feta ka lebaka la ho eketsoa ha lirafshoa tsa silicon carbide. Mofuta ona oa "lisebelisoa tse matla 'ohle" tse patiloeng indastering li fetola ka khutso tlhahiso le bophelo ba rona.
