E 'ngoe ea thepa e ncha e hapileng tlhokomelo ea bafuputsi le baenjiniere ke li-ceramic tsa mahe a linotši. Thepa ena e na le sebopeho se ikhethang sa mahe a linotši, se fanang ka melemo e mengata le ho tenyetseha ha lits'ebetso tsa eona. Sengoloa se latelang se fana ka tlhahlobo e tebileng ea li-ceramic tsa mahe a linotši, se tšohla mefuta ea tsona, litšobotsi, sebopeho sa lik'hemik'hale, mokhoa oa ho lokisa, le mefuta e mengata ea lits'ebetso liindastering tse kang likoloi, lik'hemik'hale, matla a motlakase, le tse ling. Ka ho utloisisa bokhoni ba li-ceramic tsa mahe a linotši, re ka sebelisa melemo ea tsona hamolemo le ho bula tsela bakeng sa bokamoso bo tsitsitseng le bo sebetsang haholoanyane makaleng a mangata.
1、Seemahale sa mahe a linotši ke eng
Li-ceramic tsa mahe a linotši ke sehlahisoa se secha sa letsopa se nang le sebopeho se tšoanang le sebopeho sa mahe a linotši. Qalong se ne se sebelisoa ho hloekiseng mosi o monyenyane oa likoloi, 'me joale se sebelisoa haholo liindastering tse kang lik'hemik'hale, motlakase, tšepe, peterole, lisebelisoa tsa elektroniki le mechini, ka lits'ebetso tse pharaletseng le menyetla e tšepisang. Li-ceramic tsa mahe a linotši li ka etsoa ka thepa e fapaneng, haholo-holo ho kenyeletsoa cordierite, mullite, alumina titanate, activated carbon, silicon carbide, activated alumina, zirconia, silicon nitride le matrices a kopaneng.
2、Mefuta ea Liserami tsa Mahe a Linotši
Li-ceramic tsa mahe a linotši li ka aroloa ka mekhahlelo e mene e meholo ho latela ts'ebeliso ea tsona: libaka tsa polokelo ea mocheso, thepa ea ho paka, lijari tsa catalyst le thepa ea sefe.
Metsi a polokelo ea mocheso a letsopa la mahe a linotši a na le matla a mocheso a fetang 1000 kJ/kg, ka mocheso o phahameng ka ho fetisisa oa ts'ebetso oa bonyane 1700℃. A ka boloka mafura a fetang 40% liontong tse kang liontong tse futhumatsang, liontong tsa ho baka, liontong tse kopanyang, le liontong tse petsohang, a eketsa tlhahiso ka ho feta 15%, 'me a theola mocheso oa mosi o ntšang ho fihlela ka tlase ho 150℃.
Lisebelisoa tsa ho paka tsa serame tsa mahe a linotši li na le sebaka se seholo se ikhethang le matla a matle ho feta lisebelisoa tse ling tse bōpehileng joaloka ho paka, e leng se fellang ka kabo e tšoanang ea khase le mokelikeli, khanyetso e fokotsehileng ea bethe, ts'ebetso e betere, le bophelo bo bolelele ba ts'ebeletso. Li sebelisoa e le lisebelisoa tsa ho paka indastering ea petrochemical, ea meriana le ea lik'hemik'hale tse ntle ka katleho e kholo.
Diserami tsa mahe a linotši li molemo haholo ha li sebelisoa e le li-catalyst. Ha li sebelisa thepa ea serami ea mahe a linotši e le lijari le ho sebelisa thepa e ikhethang ea ho roala, li lokisoa ka litšepe tsa bohlokoa, litšepe tsa lefats'e tse sa tloaelehang, le litšepe tsa phetoho, e leng se fellang ka ts'ebetso e phahameng ea ho kopanya, botsitso bo botle ba mocheso, bophelo bo bolelele ba ts'ebeletso, le matla a phahameng.
3、Litšobotsi tsa Liserami tsa Mahe a Linotši
Matla a phahameng, ho hanyetsa mocheso o phahameng, ho hanyetsa mafome, le ho hanyetsa ho tsofala li etsa hore li-ceramic tsa mahe a linotši li lokele masimo a fapaneng a tšireletso ea tikoloho. Lintho tse ling li kenyelletsa:
Sebaka se phahameng
Bophara bo phahameng ba masoba le bophara bo lekanang ba masoba
Ho theoha ha khatello e tlase
Koefficient e tlase ea katoloso ea mocheso
Ho thothomela ho hoholo ha mocheso le khanyetso ea ho thothomela
Ho hanyetsa ho hoholo ha dikhemikhale tse tshweu (anti-acid ≥99.8%)
Matla a phahameng a khatello
4、Sebopeho sa Lik'hemik'hale tsa Li-ceramic tsa Mahe a Linotši
Hangata mahe a linotši a letsopa a etsoa ka kaolin, talc, phofo ea aluminium le letsopa. Matsatsing ana, ka ho eketsa zeolite le lintho tse ling tse hanyetsang, ho ka fumanoa litšobotsi tse ling bakeng sa thepa ena.
Thepa ea meaho (MOC):
Cordierite
Sebopeho sa lik'hemik'hale sa Cordierite:
Alumina: 35.2±1.5%
Silika: 50.9±1.5%
Magnesia: 13.9±1.5%
5、Mokhoa oa ho Lokisetsa Li-ceramic tsa Mahe a Linotši
Diserame tsa mahe a linotši li ka etsoa ka thepa e fapaneng. Thepa ea mantlha e kenyelletsa cordierite, mullite, aluminium titanate, activated carbon, silicon carbide, activated alumina, zirconia, silicon nitride, le likarolo tse kopaneng tsa cordierite-mullite le cordierite-aluminium titanate.
Kamora ho bopa phofo kapa di-granule tsa khabone tse kentsweng tshebetsong hore e be sebopeho sa ceramic sa mahe a linotši, bokgoni ba ho hlwekisa le ho phekola metsi a ditshila bo ntlafatswa haholo, haholoholo indastering ya meriana bakeng sa ho tlosa ditshila, ho fellwa ke metsi mmeleng, le ho tlosa mmala wa dithibela-mafu, dihormone, divithamine, diente tsa nucleic acid, le diente tse ding tse fapaneng le dithethefatsi. Ha di-ceramic tsa mahe a linotši di bopjwa ka ho ntsha metsi, di-additi tse fapaneng di lokela ho eketswa ho thepa e tala e ka sehloohong ho ntlafatsa ho plasticity le ho phalla ha mmele wa letsopa. Di-additi tsena di kenyeletsa haholo-holo di-binder, di-plasticizer, di-deflocculant, di-lubricant le di-manufactant. Ho feta moo, ho boetse ho na le di-agent tse bolokang metsi, di-agent tse chelating, di-agent tse thibelang ho fetoha ha metsi, di-protective tsa colloidal, le di-surfactant. Hona jwale, starch, carboxymethyl cellulose, le polyvinyl alcohol di sebediswa haholo e le di-binder, oli ya tung le stearic acid e le di-lubricant, le glycerin e le plasticizer.
6、Litšebeliso tsa Li-ceramics tsa Mahe a Linotši
Bajari ba Catalyst
Ha di sebediswa e le dijari tsa di-catalyst, di-ceramic tsa mahe a dinotshi di sebediswa haholoholo ho hlwekiseng mosi wa koloi, ho ntsha khase ya boiler flue (NOx), ho tlosa monko wa mosi wa indasteri, le ho fedisa dikgase tse chefo le tse kotsi. Dijari tsa di-catalyst tsa ceramic tsa mahe a dinotshi tse sebediswang ho hlwekiseng mosi wa koloi haholoholo ke di-ceramic tsa mahe a dinotshi tsa cordierite tse manehilweng ka γ-Al2O3.
Thepa ea Setofo e sa Khaotseng
Thepa ea ka tlung ea letsopa ea mahe a linotši e ntšitsoeng e bobebe ka 60%-75% ho feta thepa ea ka tlung ea setso, e leng se lumellang phetiso ea mocheso ka potlako le ho besa ka potlako. Ho sebelisa li-ceramic tsa mahe a linotši e le litšehetso tsa ho besa li-ferrite kapa li-ceramic tse ling tsa elektroniki ho thusa ho ntlafatsa ts'ebetso ea lihlahisoa.
Lifilimi tsa phallo ea lebota
Diserame tsa mahe a linotši tse nang le mabota a masesaane, tse nang le masoba li ka sebelisoa ho sefa le ho hloekisa likaroloana tsa khabone likhase tsa mosi oa enjene ea disele (hoo e ka bang 500℃).
7、Qetellong, liserame tsa mahe a linotši ke thepa e feto-fetohang le e ncha e nang le sebopeho se ikhethang sa mahe a linotši se fanang ka melemo e fapaneng. Li sebelisoa liindastering tse fapaneng, ho kenyeletsoa likoloi, lik'hemik'hale, matla a motlakase, tšepe, peterole, lisebelisoa tsa elektroniki le mechini. Thepa ea tsona e ntle, joalo ka matla a phahameng, ho hanyetsa mocheso o phahameng, ho hanyetsa mafome, le ho hanyetsa ho tsofala, li etsa hore li lokele lits'ebetso tse fapaneng, ho kenyeletsoa le 'mele ea polokelo ea mocheso, lisebelisoa tsa ho paka, lijari tsa catalyst le lisebelisoa tsa sefe. Ka tsoelo-pele e tsoelang pele saenseng ea lintho tse bonahalang le tlhoko e ntseng e hola ea thepa e mosa tikolohong le e sebetsang hantle, liserame tsa mahe a linotši li ka bapala karolo ea bohlokoa haholo liindastering tse fapaneng, li tšepisa bokamoso bo khanyang bakeng sa nts'etsopele le lits'ebetso tsa tsona.
