1.Kubva kuma1960---1963, musayendisiti wekuAmerica Schwartzwalder akagadzira nzira yekuisa furo reorganic. Zviumbwa zveceramics zvine maburi zvakawanikwa nekuisa furo re ceramic slurry ne organic foam skeleton uye kubvisa zvinhu zve organics pakupisa kwakanyanya, zvichiisa musimboti wekugadzirira furo re ceramics (rine alumina base), inova ndiyo sosi yehunyanzvi hwe alumina foam ceramic chips.
2.Kubva kuma1970---1978, Mollard FR naDavidson N vekuUnited States vakagadzirafirita yefuro yealumina yedongoinogona kushandiswa pakusefa aruminiyamu alloy casting nekushandisa nzira ye organic foam impregnation ine alumina ne kaolin sezvinhu zvikuru zvekugadzira, zvichivandudza zvikuru mhando ye castings uye kuderedza mwero we strawberry, zvichiratidza kuti aruminiyamu oxide foam ceramic chips yakapinda zviri pamutemo muchikamu chekushandiswa kwemaindasitiri uye zvichikurudzira kukura kwayo kukuru.
3. Mumakore ekuma1980---Europe, United States, Japan nedzimwe nyika dzakakwikwidzana mukutsvaga nekugadzira kuti dzigadzire mafirita efoam ceramic ane zvinhu zvakasiyana-siyana uye zvirevo. Kugadzirwa kwacho kwakasimudzirwa kusvika pakugadzira michina uye otomatiki, uye zvigadzirwa zvakarongwa uye zvakajairwa.
China yakatanga kutsvakurudza nezve alumina foam ceramics kutanga kwema1980. Harbin University of Technology, Shanghai Institute of Machinery Manufacturing Technology nedzimwe nzvimbo dzakatungamira mukuita basa rakakodzera, zvishoma nezvishoma dzichiwana kuzvitonga kwetekinoroji uye kufambira mberi kwemaindasitiri, uye dzichideredza musiyano uripo nemusika wepasi rose.
Maitiro makuru ndeyekuisirwa furo reorganic uye matanho acho ndeaya anotevera:
1. Kugadzirira slurry:Sanganisa upfu hwealumina, binder, dispersant, sintering aid nemvura, kurunga kuti pave neslurry yakafanana ine huwandu hwakawanda hwakasimba uye husina kunaka.
2. Kuisa simbi mudumbu uye kuturikwa kwetsvina:Nyika furemu yefuremu yakagadzirwa kare (yakadai se polyurethane sponge) mufuremu, uye ita kuti furemu inamatire pamadziro eburi refuremu yefuremu zvakaenzana kuburikidza nekubvisa nekumonera kuti ubvise furemu yakawandisa.
3. Kuomesa nekuporesa:Isa furo mushure mekunyorovesa muovheni woomesa pa 80 - 120 ℃ kuti unamate, uwedzere simba remuviri uye kudzivirira kuchinja kweganda pakurapa kunotevera.
4. Kubvisa mafuta uye kubudisa guruu:Isai muviri wegirini wakaomeswa muchoto chinopisa moto uye mupise pa400 - 600 ℃ kuti furo reorganic uye binder zviore uye zviite ganda regirini realuminium rine maburi. Panguva ino, zvinodikanwa kudzora mwero wekupisa kudzivirira muviri wegirini kuti usatsemuke.
5. Kupisa kwakanyanya:Muviri wegirini wakabviswa mafuta unopiswa kusvika 1400 - 1600 ℃ kuti usvibise, kuitira kuti zvidimbu zvealuminium oxide zvipinde muchikamu chakasimba chekuita, tsanga dzinokura uye dzinobatana, dzichigadzira skeleton yeceramic yakasimba kwazvo, uye pakupedzisira dzichiwana aluminium oxide foam ceramic chips.
6. Kugadziriswa mushure mekuita:Cheka, porisha, uye chenesa zvinoenderana nezvinodiwa kuti uwane zvigadzirwa zvakapedzwa zvine saizi yakatarwa uye nemazvo.
1. Kureba kwakanyanya:Maburi anowanzova pakati pe60% ne90%, uye saizi yemaburi inogona kugadziriswa (kubva pama micrometer makumi kusvika kuma millimeter mashoma), nemaburi akabatana.
2. Kuwanda kwakaderera:Kuwanda kwehuwandu hwezvinhu izvi kunongova 0.3-1.2 g/cm³, yakaderera zvikuru pane yesimbi dzakakora dzealumina (inenge 3.95 g/cm³).
3. Kudzivirira kupisa kwakanyanya:Tembiricha yekushandiswa kwenguva refu inogona kusvika 1200-1600 ℃, kwenguva pfupi inogona kutsungirira tembiricha yepamusoro ye1800 ℃, isina kunyunguduka kana kupfava.
4. Kuramba ngura:Kuramba kweasidhi nealkali (kunze kwealkaline media yakasimba), kuramba kwemakemikari solvent, kupfuura zvinhu zvesimbi zvine maburi.
5.Kushanda zvakanaka kwekusefa:Maumbirwo emaburi akabatana anogona kubata zvinobudirira zvidimbu zvakasimba mumvura zvine simba shoma.
6. Kudzivirira kupisa:Kukwira kwemvura kunokanganisa kufambiswa kwemhepo nekupisa, zvichiita kuti ive chinhu chakanaka kwazvo chinodzivirira kupisa kwakanyanya.
7. Simba remuchina rine mwero:Simba rekudzvanya uye simba rekuchinjika zvinosangana nezvinodiwa zvekushandiswa mumaindasitiri, uye zvine mwero wakati wekusimba, izvo zvisingatani kupwanyika.
8. Kugona kugadzirisa zvinhu kwakasimba:Saizi dzakasiyana, maumbirwo uye PPI zvinogona kugadziriswa uye zvinogona kusangana nezvinodiwa zvemashandisirwo akasiyana.
- Munda wekusefa tembiricha yepamusoro
1. Kusefa kwesimbi kunyungudika:Pakukanda simbi dzisina ferrous dzakadai sealuminium, copper, zinc, nezvimwewo, inosefa oxide inclusions uye uncleanness particles mu melt kuti ivandudze kuchena kwe casting.
2. Kupisa kwakanyanya kwemhepo inopisa gasi:inoshandiswa kubvisa guruva remhepo inopisa zvakanyanya mumaindasitiri akadai sekugadzira simbi, makemikari, uye kupisa marara, kudzivirira zvidimbu zveguruva uye magasi anochenesa.
- Munda wekudzivirira kupisa
1. Kugadzirwa kwechoto cheindasitiri:jira rekudzivirira kupisa remaovheni eceramic, maovheni esimbi, uye maovheni egirazi kuderedza kurasikirwa nekupisa uye kuchengetedza simba.
2. Zvikamu zvemuchadenga:Sezvinhu zvinodzivirira ngarava dzemuchadenga nemainjini, zvinogona kutsungirira mamiriro ekunze anodziya zvakanyanya.
- Munda wekutakura weCatalytic
1. Kurapa kweutsi hwemotokari:Inogona kuzadzwa nezvinhu zvinokatyamadza kuti zvitsive zvimwe zvinotakura simbi, zvinoshandiswa pakushandura zvinhu zvinokuvadza muutsi.
2. Kugadzirisa makemikari:Senzira yekutakura zvinhu zvinokonzeresa makemikari, inowedzera nzvimbo yekubata zvinhu zvinokonzeresa makemikari uye inovandudza kushanda zvakanaka kwemakemikari.
- Mimwe minda
1. Kuderedza ruzha uye kudzikamisa ruzha:Inoshandiswa sezvinhu zvinobata ruzha munzvimbo dzinopisa zvakanyanya uye dzinoparadza, dzakadai senzvimbo dzeinjini uye nzvimbo dzinodzivirira ruzha mumafekitori emaindasitiri.
2. Mishonga yeBiomedicine:Zviumbwa zve alumina foam zvine hutsanana hwakanyanya zvinogona kushandiswa senzvimbo dzekugadzira mapfupa, uye zvinokwanisa kushanda zvakanaka.
