Kenyelletso ea sehlahisoa le ts'ebeliso ea silicon carbide e ntšo
Silicone carbide e ntšo(e khutsufalitsoeng e le black silicon carbide) ke thepa ea maiketsetso e seng ea tšepe e entsoeng ka lehlabathe la quartz le petroleum coke e le lisebelisoa tse ka sehloohong tse tala 'me li qhibilihisoa ka mocheso o phahameng ka sebōping sa ho hanyetsa. E na le ponahalo e ntšo-ea bohlooho-putsoa kapa botšo bo lefifi, boima bo phahameng ka ho fetisisa, conductivity e ntle ea mocheso le botsitso ba lik'hemik'hale. Ke thepa e tala e ntle haholo ea indasteri 'me e sebelisoa haholo ho li-abrasives, lisebelisoa tsa refractory, metallurgy, ceramics, electronics le masimo a mang.
Ⅰ. Litšobotsi tsa ts'ebetso ea silicon carbide e ntšo
The Mohs hardness ofsilicon e ntšo carbidee ka holimo ho 9.2, ea bobeli feela ho taemane le cubic boron nitride, 'me e na le khanyetso e matla haholo ea ho apara le ho hanyetsa tšusumetso. Sebaka sa eona sa ho qhibiliha se ka bang 2700 ° C, 'me se khona ho boloka botsitso ba sebopeho maemong a mocheso o phahameng' me ha ho bonolo ho bola kapa ho senyeha. Ho phaella moo, e na le conductivity e ntle ea mocheso le coefficient e tlaase ea ho atolosa mocheso, 'me e ntse e bontša botsitso bo babatsehang ba mocheso tlas'a mocheso o phahameng le maemo a phahameng a khatello.
Mabapi le thepa ea lik'hemik'hale, silicon carbide e ntšo e na le khanyetso e ntle ea kutu ho li-acids le alkalis, 'me e loketse ka ho khetheha bakeng sa tšebeliso ea indasteri libakeng tse thata. Ts'ebetso ea eona e phahameng e boetse e etsa hore e be lisebelisoa tse ling bakeng sa lisebelisoa tse ling tsa ho futhumatsa motlakase le masimo a semiconductor.
Ⅱ. Mefuta e meholo ea lihlahisoa le litlhaloso
Silicon carbide e ntšo e ka etsoa ka mefuta e fapaneng ho latela boholo le ts'ebeliso ea likaroloana tse fapaneng:
Lintho tse thibelang: likristale tse kholo ka mor'a ho qhibiliha, hangata li sebelisetsoa ho tsosolosa kapa e le li-additives tsa metallurgical;
Lehlabathe la granular (lehlabathe la F / P): le sebelisetsoang ho etsa mabili a silang, li-abrasives tsa sandblasting, sandpaper, joalo-joalo;
Micro powder (W, D series): e sebelisetsoa ho sila ka mokhoa o nepahetseng haholo, ho bentša, ho sila ka ceramic, joalo-joalo;
Nano-level micro powder: e sebelisetsoa lirafshoa tsa elektroniki tse phahameng haholo, lisebelisoa tse kopaneng tsa mocheso, jj.
Boholo ba likaroloana bo tloha ho F16 ho ea ho F1200, 'me boholo ba karoloana ea phofo e nyenyane e ka fihla boemong ba nanometer, e ka etsoang ho latela litlhoko tsa tekheniki tsa masimo a fapaneng a kopo.
Ⅲ. Libaka tse ka sehloohong tsa ts'ebeliso ea silicon carbide e ntšo
1. Li-abrasives le lisebelisoa tsa ho sila
Li-abrasives ke libaka tse sebelisoang ka ho fetesisa le tse sebelisoang haholo tsa silicon carbide e ntšo. Ho nka monyetla ka thepa ea eona e thata e phahameng le ea ho itšeha, silicon carbide e ntšo e ka sebelisoa ho etsa lihlahisoa tse fapaneng tsa abrasive, joalo ka mabili a sila, li-discs tse sehang, sandpaper, lihlooho tsa ho sila, li-pastes tse silang, joalo-joalo, tse loketseng ho sila le ho lokisa lisebelisoa tse kang tšepe e entsoeng ka tšepe, tšepe, tšepe e sa fereheng, lirafshoa, likhalase le lihlahisoa tsa quart.
Melemo ea eona ke lebelo la ho sila ka potlako, ha ho bonolo ho koala, le ts'ebetso e phahameng ea ts'ebetso. E sebelisoa haholo ts'ebetsong ea tšepe, tlhahiso ea mechine, mokhabiso oa mohaho le liindasteri tse ling.
2. Lisebelisoa tsa refractory
Ka lebaka la botsitso ba mocheso o phahameng le ho hanyetsa kutu, silicon carbide e ntšo e sebelisoa haholo tšimong ea thepa ea mocheso e phahameng ea mocheso. E ka etsoa ka litene tsa silicon carbide, linings tsa sebōpi, li-crucibles, li-tubes tsa ts'ireletso ea thermocouple, lisebelisoa tsa sebōpi, li-nozzles, litene tsa tuyere, joalo-joalo, 'me e sebelisoa haholo liindastering tse nang le mocheso o phahameng joaloka metallurgy, litšepe tse se nang ferrous, motlakase, khalase, samente, joalo-joalo, ho ntlafatsa bophelo ba lisebelisoa tsa ts'ebetso le ts'ireletso.
Ho phaella moo, lisebelisoa tsa silicon carbide li na le thepa e ntle ea antioxidant libakeng tse phahameng tsa mocheso oxidizing atmosphere 'me li loketse ho sebelisoa likarolong tse ka sehloohong tsa libono tse chesang tse chesang, libono le lisebelisoa tse ling.
3. Indasteri ea metallurgic
Lits'ebetsong tsa metallurgic tse kang ho etsa tšepe le ho lahla, silicon carbide e ntšo e ka sebelisoa e le deoxidizer, mocheso oa mocheso le recarburizer. Ka lebaka la lik'habone tse phahameng le ho lokolloa ha mocheso ka potlako, e ka ntlafatsa katleho ea ho qhibilihisa le ho ntlafatsa boleng ba tšepe e qhibilihisitsoeng. Ka nako e ts'oanang, e ka boela ea fokotsa lintho tse sa hloekang ts'ebetsong ea ho qhibiliha 'me ea phetha karolo ea ho hloekisa tšepe e qhibilihisitsoeng.
Lisebelisoa tse ling tsa tšepe li boetse li eketsa karolo e itseng ea silicon carbide ho fetola sebopeho sa ho qhibiliha ha tšepe e entsoeng ka tšepe le tšepe ea ductile ho boloka litšenyehelo le ho ntlafatsa ts'ebetso ea li-castings.
4. Ceramics le lisebelisoa tsa elektronike
Black silicon carbide hape ke thepa e tala ea bohlokoa bakeng sa lirafshoa tse sebetsang. E ka sebelisoa ho lokisetsa li-ceramics tsa moralo, li-ceramics tse sa tsitsang, li-ceramics tsa mocheso oa mocheso, joalo-joalo, 'me li na le litebello tse pharaletseng litabeng tsa elektronike, indasteri ea lik'hemik'hale, mechine, joalo-joalo E na le conductivity e babatsehang ea mocheso, e nang le mocheso oa mocheso ho fihlela ho 120 W / m · K,' me hangata e sebelisoa ka thepa ea mocheso oa mocheso oa mocheso le lisebelisoa tsa mocheso oa mocheso oa LED.
Ho phaella moo, silicon carbide e kene butle-butle tšimong ea li-semiconductors tsa matla 'me e fetoha lisebelisoa tsa motheo bakeng sa lisebelisoa tse phahameng tsa mocheso le tse phahameng. Leha ho hloeka ha silicon carbide e ntšo e le tlase hanyane ho feta ea silicon carbide e tala, e boetse e sebelisoa lihlahisoa tse ling tsa elektroniki tse mahareng le tse tlase.
5. Liindasteri tsa Photovoltaic le tse ncha tsa matla
Phofo e ntšo ea silicon carbide e sebelisoa haholo ho seha liphaephe tsa silicon indastering ea photovoltaic. E le abrasive ts'ebetsong ea ho seha terata ea daemane, e na le melemo ea boima bo phahameng, bo matlaho pomamatla, tahlehelo e tlase, le sebaka se boreleli sa ho itšeha, se thusang ho ntlafatsa ts'ebetso ea ho itšeha le tlhahiso ea li-wafers tsa silicon le ho fokotsa sekhahla sa tahlehelo ea liphaephe le litšenyehelo tsa tlhahiso.
Ka nts'etsopele e tsoelang pele ea matla a macha le theknoloji e ncha ea thepa, silicon carbide e ntse e ntlafatsoa bakeng sa masimo a ntseng a hlaha a kang lithium battery negative electrode additives le ceramic membrane carriers.
Ⅳ. Kakaretso le Outlook
Silicon carbide e ntšo e bapala karolo e ke keng ea nkeloa sebaka masimong a mangata a indasteri ka thepa ea eona e ntle ea mochini, mocheso le lik'hemik'hale. Ka tsoelo-pele e tsoelang pele ea theknoloji ea tlhahiso, taolo ea boholo ba lihlahisoa, ho hloekisa bohloeki le katoloso e tsoelang pele ea masimo a kopo, silicon carbide e ntšo e ntse e tsoela pele ho lebisa tshebetsong e phahameng le ho nepahala.
Nakong e tlang, ka ho phahama ka potlako ha liindasteri tse kang matla a macha, li-ceramics tsa elektronike, tse phahamengho sila le tlhahiso e bohlale, silicon carbide e ntšo e tla bapala karolo ea bohlokoa haholoanyane lefapheng la tlhahiso ea maemo a holimo le ho ba karolo ea mantlha ea sistimi e tsoetseng pele ea theknoloji.
