1.Ukususela kwiminyaka yoo-1960---Ngo-1963, isazinzulu saseMelika uSchwartzwalder sasungula indlela yokufunxa i-organic foam. Ii-ceramics ezinemingxuma zafunyanwa ngokufunxa i-ceramic slurry nge-organic foam skeleton kunye nokususa i-organics kubushushu obuphezulu, kubeka umgaqo ophambili wokulungiselela ii-foam ceramics (eziqulethe isiseko se-alumina), esisisixhobo sobuchwephesha see-alumina foam ceramic chips.
2.Ukususela kwiminyaka yoo-1970---1978, uMollard FR kunye noDavidson N base-United States baphuhlisaisihluzi sefoam se-alumina ceramicEzinokusetyenziselwa ukuhluza i-aluminium alloy casting ngokusebenzisa indlela ye-organic foam impregnation kunye ne-alumina kunye ne-kaolin njengezinto eziphambili zokwenza izinto, nto leyo ephucula kakhulu umgangatho we-castings kwaye inciphise izinga le-scrap, nto leyo ebonisa ukuba ii-aluminium oxide foam ceramic chips zingene ngokusesikweni kwinqanaba lokusetyenziswa kwemizi-mveliso kwaye zikhuthaza uphuhliso lwazo olukhulu.
3. Ngeminyaka yoo-1980---IYurophu, i-United States, iJapan kunye namanye amazwe akhuphisana kuphando nophuhliso ukwenza izihluzi ze-ceramic ze-foam ezenziwe ngezinto ezahlukeneyo kunye neenkcukacha. Imveliso yakhuthazwa yaba yeyoomatshini kunye ne-automation, kwaye iimveliso zahlulwahlulwa zaza zabekwa emgangathweni.
I-China yaqala uphando ngeeseramikhi ze-alumina foam ekuqaleni kweminyaka yoo-1980. IYunivesithi yeTekhnoloji yaseHarbin, iShanghai Institute of Machinery Manufacturing Technology kunye namanye amaziko akhokela ekwenzeni umsebenzi ofanelekileyo, eqonda kancinci kancinci ukuzimela kwezobuchwepheshe kunye nophuhliso lwemizi-mveliso, kwaye enciphisa umsantsa kwimarike yamazwe ngamazwe.
Inkqubo ephambili kukufakelwa kwe-organic foam kwaye la manyathelo ngala alandelayo:
1. Ukulungiselela i-slurry:Xuba umgubo we-alumina, i-binder, i-dispersant, i-sintering aid kunye namanzi, uxube ukuze wenze i-slurry efanayo enomthamo ophezulu oqinileyo kunye ne-viscosity ephantsi.
2. Ukufunxwa kunye nokuxhonywa kwe-slurry:faka isakhelo sefoam esilungiselelwe kwangaphambili (njengesiponji se-polyurethane) kwi-slurry, kwaye wenze i-slurry inamathele eludongeni lomngxuma wesakhelo sefoam ngokulinganayo ngokuphuma kunye nokuqengqeleka ukuze ususe i-slurry engaphezulu.
3. Ukomisa nokulungisa:Beka umzimba wefoam emva kokuxutywa kwedaka kwi-oven yokomisa uze uyomise kwi-80 - 120 ℃ ukuze uqinise iglu, uphucule amandla omzimba kwaye uthintele ukuguguleka kolu nyango lulandelayo.
4. Ukususa amafutha kunye nokukhupha iglu:Faka umzimba oluhlaza owomileyo kwisithando somlilo uze uwufudumeze kuma-400 – 600 ℃ ukuze wenze isakhelo se-organic foam kunye ne-binder zibole ngokupheleleyo kwaye ziqhekeke ukuze zenze umzimba oluhlaza we-alumina onemingxuma. Kweli nqanaba, kuyimfuneko ukulawula izinga lokufudumeza ukuthintela umzimba oluhlaza ukuba ungaqhekeki.
5. Ukutshisa okushushu okuphezulu:Umzimba oluhlaza ocociweyo ufudunyezwa ukuya kwi-1400 - 1600 ℃ ukuze utshiswe, ukuze amasuntswana e-aluminium oxide angene kwi-solid phase reaction, iinkozo zikhula kwaye zidibene ngokusondeleyo, zenze i-ceramic skeleton enamandla aphezulu, kwaye ekugqibeleni zifumane ii-aluminium oxide foam ceramic chips.
6. Ukucubungula emva:Sika, polisha, kwaye ucoce ngokweemfuno ukuze ufumane iimveliso ezigqityiweyo ezinobukhulu obuchaziweyo kunye nokuchaneka.
1. Ukuphakama okuphezulu:I-porosity idla ngokuba phakathi kwe-60% kunye ne-90%, kwaye ubungakanani be-pore bunokulungiswa (ukusuka kwi-10 yee-micrometer ukuya kwi-millimeter ezimbalwa), kunye ne-pore ezidibeneyo.
2. Uxinano oluphantsi:Ubuninzi bobuninzi buyi-0.3-1.2 g/cm³ kuphela, buphantsi kakhulu kunobo be-dense alumina ceramics (malunga ne-3.95 g/cm³).
3. Ukumelana nobushushu obuphezulu:Ubushushu bokusetyenziswa ixesha elide bunokufikelela kwi-1200-1600 ℃, okwethutyana bunokumelana nobushushu obuphezulu be-1800 ℃, ngaphandle kokunyibilika okanye ukuthamba.
4. Ukumelana nokugqwala:ukumelana ne-asidi kunye ne-alkali (ngaphandle kwe-alkaline media enamandla), ukumelana nesinyibilikisi seekhemikhali, okugqwesileyo kunezixhobo zesinyithi ezinemingxuma.
5. Ukusebenza kakuhle kokucoca:Ulwakhiwo lwemingxuma edibeneyo lunokuthintela ngokufanelekileyo amasuntswana aqinileyo kulwelo olunokumelana okuncinci kolwelo.
6. Ubushushu obuphantsi:Ukuba neembobo eziphezulu kuthintela ukuhanjiswa kobushushu kunye nokuhanjiswa kobushushu, nto leyo eyenza ukuba ibe yinto efanelekileyo yokukhusela ubushushu obuphezulu.
7. Amandla oomatshini aphakathi:Amandla okucinezela kunye namandla okugoba ahlangabezana neemfuno zokusetyenziswa kwimizi-mveliso, kwaye anomlinganiselo othile wokuqina, okungaqhekeki lula.
8. Ukwenziwa ngokwezifiso okuqinileyo:Ubungakanani obahlukeneyo, iimilo kunye ne-PPI zinokwenziwa ngokwezifiso ukuze zihlangabezane neemfuno zezicelo ezahlukeneyo.
- Intsimi yokucoca ubushushu obuphezulu
1. Ukuhluzwa kwesinyithi okunyibilikisiweyo:Xa kuphoswa iintsimbi ezingezizo i-ferrous ezifana ne-aluminium, i-copper, i-zinc, njl.njl., kucoca izinto ezifakwe kwi-oxide kunye namasuntswana angcolileyo kwi-melt ukuphucula ubunyulu be-cast.
2. Ukucoca igesi yolwelo lobushushu obuphezulu:isetyenziselwa ukususa uthuli lwegesi yolwelo olushushu kakhulu kumashishini afana ne-metallurgy, ubunjineli beekhemikhali, kunye nokutshisa inkunkuma, ukuthintela amasuntswana othuli kunye neegesi zokucoca.
- Intsimi yokukhusela ubushushu
1.I-lining ye-oven yezimboni:umaleko wokukhusela ii-oven ze-ceramic, ii-oven ze-metallurgical, kunye nee-oven zeglasi ukunciphisa ukulahleka kobushushu nokonga amandla.
2. Izinto ze-Aerospace:Njengezinto zokukhusela iinqanawa kunye neenjini, ziyakwazi ukumelana nobushushu obuphezulu.
- Intsimi yomthwali we-Catalytic
1. Unyango lokukhupha umoya ngemoto:Ingafakwa izinto ezibangela ukuba kubekho izinto ezibangela ukuba kubekho izinto ezibangela ukuba kubekho isinyithi, ezisetyenziselwa ukuguqula izinto ezinobungozi kwi-exhaust.
2. I-catalysis yekhemikhali:Njengesithwali se-catalyst kwiimpendulo zamakhemikhali, yonyusa indawo yokudibana kwe-reaction kwaye iphucula ukusebenza kakuhle kwe-catalytic.
- Ezinye iintsimi
1. Ukufunxwa kwesandi kunye nokunciphisa ingxolo:Isetyenziswa njengezinto ezifunxa isandi kwiindawo ezinobushushu obuphezulu nezinobuthi, ezifana neendawo zenjini kunye neengqimba zokuthintela isandi kwizityalo zoshishino.
2. Unyango lweBiomedicine:Iiseramiki ze-alumina foam ezicocekileyo kakhulu zingasetyenziswa njengee-scaffolds zobunjineli bezicubu zethambo, kwaye zihambelana kakuhle ne-biocompatibility.
