1. Kusukela ngawo-1960---1963, usosayensi waseMelika uSchwartzwalder wasungula indlela yokufaka i-foam ephilayo. Izitsha zobumba ezinezimbobo zatholakala ngokufaka i-ceramic slurry nge-organic foam skeleton nokususa izinto eziphilayo ekushiseni okuphezulu, okubeka isimiso sokulungiselela esiyinhloko sezitsha zobumba ze-foam (eziqukethe isisekelo se-alumina), okuwumthombo wobuchwepheshe wezitsha zobumba ze-alumina foam.
2. Kusukela ngawo-1970---1978, uMollard FR noDavidson N base-United States basungulaisihlungi se-foam se-alumina ceramicezingasetshenziselwa ukuhlunga i-aluminium alloy casting ngokusebenzisa indlela ye-organic foam impregnation ene-alumina ne-kaolin njengezinto zokusetshenziswa eziyinhloko, okuthuthukisa kakhulu ikhwalithi ye-castings nokunciphisa izinga le-scrap, okubonisa ukuthi ama-chips e-aluminium oxide foam ceramic angene ngokusemthethweni esigabeni sokusetshenziswa kwezimboni futhi akhuthaza intuthuko yawo enkulu.
3. Ngawo-1980---IYurophu, i-United States, iJapane kanye namanye amazwe ancintisana ocwaningweni nasekuthuthukisweni ukuze akhe izihlungi ze-foam ceramic zezinto ezahlukahlukene kanye nemininingwane. Ukukhiqizwa kwakhushulelwa ekusetshenzisweni kwemishini kanye nokwenza izinto ngokuzenzakalela, futhi imikhiqizo yahlelwa ngokwezigaba futhi yabekwa ezingeni elifanayo.
IShayina yaqala ucwaningo lwe-alumina foam ceramics ekuqaleni kwawo-1980. IHarbin University of Technology, iShanghai Institute of Machinery Manufacturing Technology kanye nezinye izikhungo zahola ekwenzeni umsebenzi ofanele, kancane kancane zaqaphela ukuzimela kwezobuchwepheshe kanye nokuthuthukiswa kwezimboni, futhi zanciphisa igebe emakethe yamazwe ngamazwe.
Inqubo eyinhloko ukufakwa kwe-foam ephilayo futhi izinyathelo zimi kanje:
1. Ukulungiselela i-slurry:Hlanganisa i-alumina powder, i-binder, i-dispersant, i-sintering aid kanye namanzi, hlanganisa ukuze wenze i-slurry efanayo enokuqukethwe okuphezulu okuqinile kanye ne-viscosity ephansi.
2. Ukuminza kanye nokulenga kwe-slurry:Faka uhlaka lwe-foam oluyimvelo olusetshenziselwe kusengaphambili (njenge-polyurethane sponge) ku-slurry, bese wenza i-slurry inamathele odongeni lwembobo yohlaka lwe-foam ngokulinganayo ngokuphuma nokugoqa ukuze ususe i-slurry eningi.
3. Ukomisa nokulungisa:Beka umzimba we-foam ngemva kokulutheka ulenga kuhhavini owomile bese uwumisa ku-80 - 120 ℃ ukuze uqinise ingcina, uthuthukise amandla omzimba futhi uvimbele ukuguguleka ekwelashweni okulandelayo.
4. Ukususa amafutha nokukhipha iglue:faka umzimba oluhlaza okomile esithandweni sokushisa bese uwushisa ku-400 - 600 ℃ ukuze uhlaka lwe-foam oluphilayo kanye ne-binder zibole ngokuphelele futhi ziqhekeke ukuze kwakheke umzimba oluhlaza we-alumina onezimbobo. Kulesi sigaba, kuyadingeka ukulawula izinga lokushisa ukuze kuvinjelwe umzimba oluhlaza ukuthi ungaqhekeki.
5. Ukushisa okuphezulu kokushisa:Umzimba oluhlaza osusiwe amafutha ushiswa ku-1400 - 1600 ℃ ukuze ushise, ukuze izinhlayiya ze-aluminium oxide zenze ukusabela kwesigaba esiqinile, okusanhlamvu kuyakhula futhi kuhlangana eduze, kwakha uhlaka lwe-ceramic olunamandla aphezulu, futhi ekugcineni kutholakale ama-chips e-ceramic e-aluminium oxide foam.
6. Ukucutshungulwa ngemuva:Sika, pholisha, futhi uhlanze ngokwezidingo ukuze uthole imikhiqizo eqediwe enobukhulu obubekiwe kanye nokunemba.
1. I-porosity ephezulu:Imbobo ngokuvamile iphakathi kuka-60% no-90%, futhi usayizi wembobo ungalungiswa (kusukela kumashumi ama-micrometer kuya kumamilimitha ambalwa), ngamambobo axhumene.
2. Ubuningi obuphansi:Ubuningi bezinto ezisetshenziswayo bungu-0.3-1.2 g/cm³ kuphela, buphansi kakhulu kunobobumba be-alumina obukhulu (cishe u-3.95 g/cm³).
3. Ukumelana nokushisa okuphezulu:Izinga lokushisa lokusetshenziswa kwesikhathi eside lingafinyelela ku-1200-1600 ℃, isikhathi esifushane singamelana nokushisa okuphezulu okungu-1800 ℃, ngaphandle kokuncibilika noma ukuthamba.
4. Ukumelana nokugqwala:ukumelana ne-asidi ne-alkali (ngaphandle kwemidiya enamandla ye-alkaline), ukumelana ne-solvent yamakhemikhali, okungcono kunezinto zensimbi ezinezimbobo.
5. Ukusebenza kahle kokuhlunga:Isakhiwo sembobo esixhunyiwe singavimba ngempumelelo izinhlayiya eziqinile oketshezini olunokumelana okuphansi koketshezi.
6. Ukufakwa kokushisa:Ukuvuleka okuphezulu kuvimbela ukuqhutshwa kokushisa kanye nokuguqulwa komoya, okwenza kube yinto enhle kakhulu yokuvikela ukushisa okuphezulu.
7. Amandla aphakathi okusebenza ngomshini:Amandla okucindezela kanye namandla okuguquguquka kuhlangabezana nezidingo zokusetshenziswa kwezimboni, futhi kunezinga elithile lokuqina, okungaphuphuki kalula.
8. Ukwenziwa ngokwezifiso okuqinile:Osayizi abahlukene, izimo kanye ne-PPI kungenziwa ngezifiso ukuze kuhlangatshezwane nezidingo zezinhlelo zokusebenza ezahlukene.
- Insimu yokuhlunga yokushisa okuphezulu
1. Ukuhlunga okuncibilikisiwe kwensimbi:Uma kuphonswa izinsimbi ezingezona i-ferrous njenge-aluminium, ithusi, i-zinc, njll., kuhlunga izinto eziqukethwe yi-oxide kanye nezinhlayiya zokungcola ekuncibilikeni ukuze kuthuthukiswe ubumsulwa bophonswa.
2. Ukuhlunga igesi yoketshezi lokushisa eliphezulu:isetshenziselwa ukususa uthuli lwegesi yomoya oshisayo oshisa kakhulu ezimbonini ezifana ne-metallurgy, ubunjiniyela bamakhemikhali, kanye nokushiswa kwemfucuza, ukuvimba izinhlayiya zothuli kanye namagesi okuhlanza.
- Insimu yokushisa
1. Ukufakwa kwe-oven yezimboni:ungqimba lokuvikela ama-oven e-ceramic, ama-oven e-metallurgical, nama-oven engilazi ukunciphisa ukulahleka kokushisa nokonga amandla.
2. Izingxenye ze-Aerospace:Njengezinto zokuvikela izindiza kanye nezinjini, zingamelana nezimo zokushisa eziphakeme.
- Insimu yenkampani yokuthwala i-Catalytic
1. Ukwelashwa kokukhipha igesi ngezimoto:Ingafakwa ama-catalyst ukuze ithathe indawo yezinye izithwali zensimbi, ezisetshenziselwa ukuguqula izinto eziyingozi emsipheni.
2. I-catalysis yamakhemikhali:Njengomthwali we-catalyst ekusabeleni kwamakhemikhali, kwandisa indawo yokuxhumana kokusabela futhi kuthuthukisa ukusebenza kahle kwe-catalytic.
- Ezinye izinkambu
1. Ukumuncwa komsindo kanye nokunciphisa umsindo:Isetshenziswa njengezinto ezibamba umsindo ezindaweni ezishisa kakhulu nezigqwalayo, njengezingxenye zenjini kanye nezendlalelo zokuvimbela umsindo ezitshalweni zezimboni.
2. Imithi ye-Biomedicine:Izitsha zobumba ze-alumina foam ezihlanzekile kakhulu zingasetshenziswa njengezicafu zobunjiniyela bezicubu zamathambo, ezinokuhambisana okuhle kwezinto eziphilayo.
