1. Ho tloha lilemong tsa bo-1960---1963, rasaense oa Amerika Schwartzwalder o ile a qapa mokhoa oa ho kenya foam ea tlhaho. Li-ceramic tse nang le masoba li fumanoe ka ho kenya slurry ea ceramic ka masapo a foam ea tlhaho le ho tlosa lintho tse phelang mochesong o phahameng, ho beha molao-motheo oa mantlha oa ho lokisa li-ceramic tsa foam (tse nang le motheo oa alumina), e leng mohloli oa tekheniki oa li-chips tsa ceramic tsa foam ea alumina.
2. Ho tloha lilemong tsa bo-1970---1978, Mollard FR le Davidson N ba United States ba ile ba thehafiltara ea foam ea ceramic ea aluminae ka sebelisoang bakeng sa ho sefa aluminium alloy casting ka ho sebelisa mokhoa oa ho kenya foam ea tlhaho ka alumina le kaolin e le thepa ea mantlha e tala, e ntlafatsang boleng ba castings haholo le ho fokotsa sekhahla sa lithōle, e leng se bontšang hore li-chips tsa ceramic tsa aluminium oxide foam li kene ka molao mohatong oa ts'ebeliso ea indasteri le ho khothaletsa nts'etsopele ea tsona e kholo.
3. Lilemong tsa bo-1980---Yuropa, United States, Japane le linaha tse ling li ile tsa qothisana lehlokoa lipatlisisong le nts'etsopele ho theha lifilthara tsa foam ceramic tsa thepa le litlhaloso tse fapaneng. Tlhahiso e ile ea phahamisetsoa ho ea ho mechine le boiketsetso, 'me lihlahisoa li ile tsa hlophisoa ka tatellano le ho lekanngoa.
Chaena e qalile lipatlisiso tsa liseramike tsa foam tsa alumina mathoasong a lilemo tsa bo-1980. Harbin University of Technology, Setsi sa Shanghai sa Theknoloji ea Tlhahiso ea Mechini le litsi tse ling li ile tsa etella pele ho etseng mosebetsi o amehang, butle-butle tsa hlokomela boipuso ba theknoloji le indasteri, le ho fokotsa sekheo le 'maraka oa machaba.
Ts'ebetso e ka sehloohong ke ho kenngoa ha foam ea tlhaho 'me mehato ke e latelang:
1. Tokisetso ea seretse:Kopanya phofo ea alumina, binder, dispersant, sintering aid le metsi, hlohlelletsa ho etsa slurry e tšoanang e nang le dikahare tse ngata tse tiileng le viscosity e tlase.
2. Ho kenngwa le ho fanyeha ha lerōle:Kenya moralo oa foam ea tlhaho o entsoeng esale pele (joalo ka seponche sa polyurethane) ka har'a lerōle, 'me u etse hore lerōle le khomarele leboteng la lesoba la moralo oa foam ka ho lekana ka ho ntša le ho pitikisa ho tlosa lerōle le feteletseng.
3. Ho omisa le ho phekola:Beha 'mele oa foam ka mor'a hore lerōle le fanyehoe ka ontong e omisang 'me u o omise ka mocheso oa 80 - 120 ℃ ho tiisa sekhomaretsi, ho ntlafatsa matla a 'mele le ho thibela ho fetoha ha 'mele kalafong e latelang.
4. Ho tlosa mafura le ho ntša sekhomaretsi:Kenya 'mele o motala o omisitsoeng ka sebōping sa ho chesa 'me u o chese ka mocheso oa 400 - 600 ℃ ho etsa hore moralo oa foam le binder tsa tlhaho li bole ka ho feletseng le ho fetoha 'mele o motala oa alumina o nang le masoba. Mothating ona, ho hlokahala ho laola sekhahla sa ho futhumatsa ho thibela 'mele o motala hore o se ke oa petsoha.
5. Ho chesa mocheso o phahameng:'Mele o motala o tlositsoeng mafura o futhumatsoa ho fihlela ho 1400 - 1600 ℃ bakeng sa ho sila, e le hore likaroloana tsa aluminium oxide li fete mohatong o tiileng, lithollo lia hola 'me li kopana haufi-ufi, li etsa skeleton ea ceramic e matla haholo, 'me qetellong li fumana li-chips tsa ceramic tsa foam tsa aluminium oxide.
6.Ts'ebetso ea kamora:Seha, bentša, 'me u hloekise ho latela litlhoko ho fumana lihlahisoa tse felileng tse nang le litekanyo le ho nepahala ho boletsoeng.
1. Ho ba le masoba a maholo:Hangata masoba a manyane a pakeng tsa 60% le 90%, 'me boholo ba masoba bo ka fetoloa (ho tloha ho mashome a di-micrometer ho isa ho dimilimithara tse mmalwa), ka masoba a hokahaneng.
2.Bongata bo tlase:Bongata ba bongata ke 0.3-1.2 g/cm³ feela, e leng tlase haholo ho feta ea li-ceramics tse teteaneng tsa alumina (hoo e ka bang 3.95 g/cm³).
3.Khanyetso e phahameng ea mocheso:Mocheso oa tšebeliso ea nako e telele o ka fihla ho 1200-1600 ℃, oa nako e khuts'oane o ka mamella mocheso o phahameng oa 1800 ℃, ntle le ho qhibiliha kapa ho nolofala.
4.Khanyetso ea ts'enyeho:ho hanyetsa asiti le alkali (ntle le metswedi e matla ya alkaline), ho hanyetsa dikhemikhale tsa ho qhibilihisa, ho feta thepa e nang le masoba a tshepe.
5.Ts'ebetso e ntle ea ho sefa:Sebopeho sa masoba a hokahaneng se ka thibela ka katleho dikarolwana tse tiileng mokelikeling tse nang le khanyetso e tlase ya mokelikeli.
6. Ho kenya mocheso ka mocheso:Ho ba le masoba a mangata ho sitisa ho tsamaisa mocheso le ho tsamaisa mocheso ka potlako, e leng se etsang hore e be thepa e ntle ea ho thibela mocheso ka mocheso o phahameng.
7. Matla a itekanetseng a mechini:Matla a ho hatella le matla a ho kobeha li fihlela litlhoko tsa ts'ebeliso ea indasteri, 'me li na le tekanyo e itseng ea ho tiea, e leng se sa robeheng habonolo.
8. Ho iketsetsa lintho ka mokhoa o matla:Boholo bo fapaneng, dibopeho le PPI di ka etswa hore e be tsa hao mme e ka fihlela ditlhoko tsa ditshebediso tse fapaneng.
- Tšimo ea ho sefa mocheso o phahameng
1. Ho sefa ha tšepe e qhibilihang:Ha e lahla litšepe tse se nang ferrous tse kang aluminium, koporo, zinki, jj., e sefa lintho tse kenyellelitsoeng ho oxide le likaroloana tse sa hloekang tse qhibilihang ho ntlafatsa bohloeki ba lahla.
2. Sefa sa khase sa flue se nang le mocheso o phahameng:e sebediswang bakeng sa ho tlosa lerōle la khase e futhumatsang mocheso o phahameng diindastering tse kang tsa tšepe, boenjiniere ba lik'hemik'hale, le ho chesa litšila, ho thibela likaroloana tsa lerōle le likhase tse hloekisang.
- Tšimo ea ho thibela mocheso
1. Lesela la ontong la indasteri:lera la ho thibela mocheso bakeng sa li-oven tsa ceramic, li-oven tsa tšepe, le li-oven tsa khalase ho fokotsa tahlehelo ea mocheso le ho boloka matla.
2. Likarolo tsa sebaka sa lifofane:Jwalo ka thepa ya ho thibela difofane le dienjene, di ka mamella maemo a mocheso o phahameng.
- Tšimo ea catalytic carrier
1. Kalafo ea mosi oa likoloi:E ka tlatsoa ka di-catalyst ho nkela dijari tse ding tsa tshepe sebaka, tse sebediswang bakeng sa phetoho ya di-catalyst ya dintho tse kotsi ka hara mosi.
2. K'hemik'hale ea lik'hemik'hale:Jwalo ka mojari wa di-catalyst dikarabelong tsa dikhemikhale, e eketsa sebaka sa ho kopana ha karabelo mme e ntlafatsa bokgoni ba ho kopanya di-catalytic.
- Masimo a mang
1. Ho monya le ho fokotsa lerata ha molumo:E sebelisoa e le thepa e monyang molumo libakeng tse nang le mocheso o phahameng le tse senyang, tse kang likarolo tsa enjene le likarolo tsa ho thibela molumo lifemeng tsa indasteri.
2. Bongaka ba Bayomediki:Liserami tsa foam tsa alumina tse hloekileng haholo li ka sebelisoa e le li-scaffolds tsa boenjiniere ba lisele tsa masapo, tse nang le tšebelisano e ntle ea bio.
