Melemo ea Li-Tube tsa Khanya tsa Silicon Carbide

Lefapheng la ditharollo tsa ho futhumatsa diindasteri,liphaephe tse khanyang tsa silicon carbidee se e le baeta-pele, ba hapa tlhokomelo ka lebaka la ts'ebetso ea bona e phahameng le botšepehi. Sehlahisoa sena se secha se etselitsoe ho mamella mocheso o feteletseng, e leng se etsang hore se be se loketseng lits'ebetso tse fapaneng, ho kenyeletsoa lionto, lionto le libaka tse ling tse nang le mocheso o phahameng. Melemo ea li-tubes tse khanyang tsa silicon carbide e mengata, 'me ho li utloisisa ho ka thusa liindasteri ho etsa liqeto tse nang le tsebo mabapi le litsamaiso tsa tsona tsa ho futhumatsa.

E 'ngoe ea melemo e hlahelletseng ka ho fetisisa ea li-tubes tsa silicon carbide radiant ke ho hanyetsa ha tsona mocheso o phahameng ka ho ikhethang. Li-tubes tsena li ka sebetsa hantle mochesong o fetang likhato tse 1,600 tsa Celsius (2,912 likhato tsa Fahrenheit), e leng sa bohlokoa ho liindasteri tse hlokang ho futhumatsa ka mokhoa o tsitsitseng le o tšepahalang. Bokhoni bona ba mocheso o phahameng bo lumella ts'ebetso e sebetsang ea thepa, ho netefatsa hore kemiso ea tlhahiso e ka finyelloa ntle le ho beha boleng kotsing. Bokhoni ba ho boloka botsitso ba sebopeho maemong a feteletseng joalo bo khetholla li-tubes tsa silicon carbide radiant ho litharollo tse ling tsa ho futhumatsa, e leng se etsang hore e be khetho e ratoang bakeng sa bahlahisi ba bangata.

Ho tsamaisa mocheso ke molemo o mong oa bohlokoa oa lipeipi tsa mahlaseli tsa silicon carbide. Thepa e ikhethang ea thepa ena e nolofalletsa phetiso e sebetsang hantle ea mocheso, e leng ea bohlokoa bakeng sa lits'ebetso moo ho futhumatsa ka mokhoa o ts'oanang ho hlokahalang. Ho tsamaisa mocheso ka mokhoa o sebetsang hantle ho netefatsa hore mocheso o ajoa ka ho lekana ho pholletsa le tube ea mahlaseli, ho fokotsa libaka tse chesang le ho netefatsa mocheso o tsitsitseng holim'a bokaholimo bohle bo futhumetseng. Ka lebaka leo, liindasteri li ka fihlela ts'ebetso e ntle ea matla le ho fokotsa litšenyehelo tsa ts'ebetso, ho etsa hore lipeipi tsa mahlaseli tsa silicon carbide e be tharollo e theko e tlaase bakeng sa lits'ebetso tsa mocheso o phahameng.

Ntle le ho hanyetsa mocheso o phahameng le ho tsamaisa mocheso hantle, li-tube tsa mahlaseli tsa silicon carbide le tsona li na le ho hanyetsa ho futhumatsa hantle. Tšobotsi ena e bohlokoa haholo libakeng tseo ho pepesehela oksijene ho ka bakang ho senyeha ka potlako ha likarolo tsa ho futhumatsa. Ho hanyetsa ho futhumatsa ha silicon carbide ho netefatsa hore li-tube tse futhumatsang li boloka ts'ebetso ea tsona ka nako e telele, ho fokotsa tlhoko ea ho nkeloa sebaka khafetsa le ho fokotsa nako ea ho se sebetse ts'ebetsong ea tlhahiso. Ho tšoarella hona ha ho lelefatse feela bophelo ba sistimi ea ho futhumatsa, empa hape ho boloka litšenyehelo ka kakaretso tsa k'hamphani.

Ho tsitsa ha lik'hemik'hale ke ntlha e 'ngoe e hlahelletseng ea li-tube tsa mahlaseli a silicon carbide. Litšebelisong tse ngata tsa indasteri, likarolo tsa ho futhumatsa li pepesehela lik'hemik'hale tse fapaneng le lintho tse senyang. Ho hanyetsa lik'hemik'hale ho matla ha silicon carbide ho e lumella ho mamella tikoloho e thata ntle le ho senyeha kapa ho lahleheloa ke katleho. Ho tsitsa hona ho bohlokoa liindastering tse kang tsa letsopa, khalase le ts'ebetso ea tšepe, moo lik'hemik'hale tse senyang li ka sitisang ts'ebetso ea likarolo tsa ho futhumatsa tsa setso. Ka ho sebelisa li-tube tsa mahlaseli a silicon carbide, lik'hamphani li ka netefatsa hore litsamaiso tsa tsona tsa ho futhumatsa li lula li tšepahala ebile li sebetsa hantle esita le tlas'a maemo a thata.

Ho phaella moo, ho tenyetseha ha di-tube tsa silicon carbide radiant ho etsa hore di lokele mefuta e mengata ya ditshebediso. Ho tloha kalafong ya mocheso wa tshepe ho isa ho ho besa ka ceramic, di-tube tsena di ka fetolwa ho latela ditlhoko tse ikgethang tsa diindasteri tse fapaneng. Tshebetso ya tsona e ntle maemong a fapaneng, hammoho le ho hanyetsa ha tsona mocheso o phahameng le bokgoni ba mocheso, di di etsa kgetho e kgahlehang bakeng sa bahlahisi ba batlang ho ntlafatsa mekgwa ya ho futhumatsa. Ho tenyetseha hona ho tiisa di-tube tsa silicon carbide radiant e le kgetho e etellang pele mmarakeng.

Qetellong, tlhoko e ntseng e hola ea litharollo tsa ho futhumatsa tse bolokang eneji le tse tšoarellang e ntse e hohela botumo ba li-tube tsa mahlaseli tsa silicon carbide. Ha liindasteri li ntse li loanela ho fokotsa khatello ea tsona ea khabone le ho ntlafatsa ts'ebetso ea matla, ho sebelisa likarolo tsena tse tsoetseng pele tsa ho futhumatsa ho tsamaisana le lipheo tsa tsona. Li-tube tsa mahlaseli tsa silicon carbide ha li fane feela ka ts'ebetso e phahameng, empa li boetse li thusa ho fokotsa ts'ebeliso ea matla, li etsa hore e be khetho e mosa tikolohong. Ka ho tsetela theknolojing ea silicon carbide, lik'hamphani li ka ntlafatsa ts'ebetso e ntle ha li ntse li tšehetsa merero ea ts'ireletso.

Ka bokhutšoanyane, melemo ea li-tube tsa silicon carbide tse khanyang e hlakile. Ho hanyetsa ha tsona mocheso o phahameng, ho tsamaisa mocheso hantle, ho hanyetsa oxidation le botsitso ba lik'hemik'hale ho li etsa hore li be molemo bakeng sa mefuta e fapaneng ea lits'ebetso tsa indasteri. Ha liindasteri li ntse li tsoela pele ho batla litharollo tse ncha tsa ho ntlafatsa ts'ebetso le ho fokotsa litšenyehelo, li-tube tsa silicon carbide tse khanyang li hlahella e le khetho e tšepahalang le e sebetsang. Ka melemo ea tsona ea ho tenyetseha le botsitso, li-tube tsena tse khanyang li lebelletsoe ho bapala karolo ea bohlokoa mahlaleng a nakong e tlang a ho futhumatsa indasteri.
