I-Metal Foam ibhekisela ezintweni zensimbi ezikhethekile ezinezimbotshana zegwebu.Ngezici zayo eziyingqayizivele zesakhiwo, igwebu lensimbi linochungechunge lwezinzuzo ezinhle, njengokuminyana okuphansi, ukusebenza kahle kokufakwa kokushisa, ukusebenza kahle kokufakwa komsindo nekhono lokumunca amagagasi kagesi.

Inokungena komoya okuphezulu, cishe wonke ama-pores axhunyiwe, i-BET yama-pores inkulu futhi incane kakhulu.

Izigaba ze-Metal Foam

I-Metal Foam ikakhulukazi njengegwebu le-aluminium, igwebu lethusi, igwebu le-nickel namanye ama-alloys foam.

Igwebu le-aluminium elinama-alloys linesisindo esincane futhi linezici zokumuncwa komsindo, ukuvala ukushisa, ukunciphisa ukudlidliza, ukumuncwa kwamandla okushaqeka kanye namagagasi kagesi, njll. idivayisi yokunciphisa ukudlidliza kwe-electromechanical, isembozo sokuvikela igagasi le-electromagnetic sokuphakelwa kwamandla kagesi, njll.

Ngenxa yesakhiwo se-pore esixhunyiwe kanye ne-porosity ephezulu, i-nickel foam inokusebenza kwegesi ephezulu, indawo ethile ephezulu kanye namandla e-capillary. Isetshenziswa kakhulu njengento esebenzayo ukwenza izihlungi eziwuketshezi, ama-atomizer, iziguquli ze-catalytic, amapuleti ebhethri nezishintshi zokushisa zangaphambili.

Igwebu le-Copper line-conductivity enhle kanye ne-ductility, izindleko eziphansi zokulungiselela kunegwebu le-nickel, kanye nokuhamba okungcono, ngakho-ke ingasetshenziswa ekulungiseni izinto ze-anode yebhethri (inkampani yenethiwekhi), abathwali be-catalyst kanye nezinto zokuvikela i-electromagnetic.

Ikakhulukazi, i-foam yethusi isetshenziswa njengento eyisisekelo ye-electrode yebhethri, enezinzuzo ezisobala. Kodwa-ke, ukumelana nokugqwala kwethusi akukuhle njenge-nickel, okukhawulela ukusetshenziswa kwayo.

Izicelo ze-Metal Foam

Amagwebu ensimbi anamandla athile, i-ductility kanye ne-addability, futhi angasetshenziswa njengezinto zokwakha ezingasindi.Le nto kade yasetshenziswa njengento ewumgogodla yeziqeshana zezindiza.Embonini ye-aerospace ne-missile, amagwebu ensimbi asetshenziswa njengento engasindi, edlulisa ukushisa. izakhiwo zokusekela.Ngenxa yokuthi ingashiselwa, inamathiselwe noma ifakwe ngogesi esakhiweni, ingenziwa ibe yilungu eliphethe isangweji. Njengokwesekwa kwe igobolondo lensimbi lephiko, ukusekelwa kokulwa nokuwa kwekhala lekhala lomcibisholo (ngenxa ye-conductivity enhle yokushisa) kanye negiya lokufika le-spacecraft, njll.

Ekwakhiweni, igwebu lensimbi liyadingeka ukuze kwenziwe izakhi, izinsimbi, noma izisekelo ezikwazi ukumelana nokukhanya, eziqinile, noma izisekelo zalezi zinto. kokubili ukumuncwa kwamandla kanye nezici ezithwalayo ukuze kuncishiswe ukusetshenziswa kwamandla.Amagobolondo angama-cylindrical asetshenziswa kakhulu ezakhiweni zobunjiniyela, njengamafuselage endiza namafutha asogwini. I-RIGS.Amagobolondo angama-cylindrical anezindonga ezincane ajwayele ukulimala uma engaphansi kwemithwalo, kodwa uma igobolondo lisekelwa igwebu eliqhubekayo: amakhoyili, isakhiwo sinamandla amakhulu kunegobolondo eliphakathi elingaqinisiwe lobubanzi nosayizi ofanayo.

Igwebu le-Copper kulula ukukhiqiza futhi kulula ukuligoba, ngakho lifanele izinsimbi.

Amagwebu ensimbi angasetshenziswa futhi njengeziqinisi zezinto eziningi eziphilayo, ezingaphili nezensimbi.Isibonelo, impahla ye-nickel foam eqinisiwe ye-aluminium alloy (NFRA) yenziwa ngemva kokuqiniswa ngokugcwalisa i-aluminium encibilikisiwe kugwebu le-nickel.

Insimbi ye-Foam ifaneleka kakhulu ukuthi isetshenziswe njengendwangu ye-roll engasindi yokuthwala amapaneli ahlukahlukene, amagobolondo namashubhu ukuze kwenziwe izinhlanganisela ze-laminated ezihlukahlukene.Isibonelo esivamile sokusetshenziswa kwezinto ezimboza izimbotshana ezingxenyeni zesakhiwo amapaneli e-sandwich.Amapaneli e-Sandwich asetshenzisiwe asetshenzisiwe. endizeni yesimanje sebenzisa ingilazi noma isikhumba se-carbon fibre composite.Lolu ungqimba lwesikhumba luhlukaniswa nensimbi yekhekheba lezinyosi nge-aluminium yensimbi noma iphepha, noma ngegwebu le-polymer eliqinile ukuze linikeze. iphaneli yesangweji ukuqina okukhulu okugoba okuqondile kanye namandla athile okugoba.Ubuchwepheshe obufanayo buye banwetshwa kwezinye izinhlelo zokusebenza lapho isisindo siyinkomba eyinhloko: imikhumbi-mkhathi, izihlibhi, izikebhe zomjaho kanye nezakhiwo ezihambayo.

Ukuvikelwa kwe-buffer nakho kungenye yezindlela eziyinhloko zokusetshenziswa kwamagwebu ensimbi, okumele abe namandla okumunca amandla ngenkathi elawula amandla amakhulu asebenza entweni okufanele ivikelwe ngaphansi komkhawulo wokudala umonakalo.

Amagwebu angama-porous afaneleka kahle izicelo ezinjalo.Ngokulawula ukuminyana kwayo okuhlobene, amandla amagwebu ensimbi angalungiswa phezu kobubanzi obubanzi.
