1. Iyini i-Foamed Metal ne-Foamed Aluminium
Ngokuhamba komlando, ukutholakala kwezinsimbi ezinegwebu kwenza ingqopha-mlando ebalulekile ekuguqukeni kwawo wonke umkhakha wobunjiniyela bezinto zokwakha. I-foam yensimbi yinto equkethe isakhiwo sensimbi enenani elikhulu lama-pores agcwele amagesi eduze kwesakhiwo. Ama-pores alawa magwebu ensimbi angaba ngendlela yokuxhumana noma izimpawu ze-hermetic, ezaziwa ngokuthi ama-open-cell kanye namagwebu amaseli avaliwe, ngokulandelana. Phakathi kwazo,i-aluminium foamnjengamanje iyinsimbi eyigwebu enamandla amakhulu okusetshenziswa, futhi yaziwa ngokuthi “inkanyezi yensimbi” ngenxa yochungechunge lwezakhiwo ezinhle kakhulu, njengokuvunwa okuphezulu, ukuminyana okuphansi, isisindo esilula, amandla aphezulu, ukucindezela okuhle, ukumuncwa komthelela omuhle, ukumuncwa okuhle komsindo, nokuvikela i-electromagnetic. "inkanyezi yensimbi", esetshenziswa kabanzi kubunjiniyela be-aerospace, ukukhiqiza nezinye izindlela zokucubungula emkhakheni wesayensi yemvelo.

Izici zesakhiwo segwebu le-aluminium: (a) Igwebu le-aluminium elivuliwe; (b) Igwebu le-aluminium yeseli evaliwe

2. Izakhiwo kanye Nezicelo zeI-Aluminium Foam
I-aluminium Foam iyinsimbi ene-porosity ephezulu kanye nesakhiwo se-porous, lapho izimbotshana ezivaliwe zibalelwa cishe izingxenye ezintathu kwezine zomthamo ophelele wezinto zensimbi, okwenza izinto zibe lula kakhulu. Ngaphezu kwalezi zakhiwo, igwebu le-aluminium linezakhiwo ezihlaba umxhwele zokumunca amandla kanye nokucindezelwa okuphezulu. Ngokuphathelene nokuminyana, abacwaningi bathola ukuthi amasampula amaningi egwebu le-aluminium anesisindo esingaba ngu-0.4-1.2 g-cm-3. Ngaphezu kwalokho, igwebu le-aluminium liyamunca umsindo, likwazi ukuphinda lisetshenziswe futhi line-thermal conductivity ephansi.

Isakhiwo se-bilge esithuthukisiwe esimelana nomthelela: 1 - isikhumba esingaphezulu; 2 -i-aluminiumi-foam truss; 3 - isikhumba esiphansi

Mayelana nezinhlelo zokusebenza, ukuvikela kazibuthe kagesi, izakhiwo ezingasindi futhi ezimunca igwebu le-aluminium ziyenza ibe yikhandidethi efanelekile yezingxenye ezisetshenziswa kumishini ehlanganisiwe elawulwayo, izimboni zezimoto, i-aerospace kanye nezokwakha ngenxa yekhono layo lokumelana nezimo ezibucayi. Emadivaysi e-fusion alawulwayo, i-aluminium foam yeseli evaliwe iyinto enhle kakhulu yokuvikela i-electromagnetic. Ngenxa yokuxhumana kohlaka lwamathambo e-aluminium foam, olunendawo enkulu ethize kanye nekhono elihle lokumunca futhi libonise amagagasi kagesi, izinhlobo ezahlukene zokulahlekelwa, njengokulahleka kokumuncwa kanye nokulahlekelwa kokubonisa, kwenzeka kugwebu le-aluminium, elinikeza ukukhanya. I-foam aluminium enhle kakhulu ye-electromagnetic shielding properties. Futhi kutholakale ukuthi ukusebenza kahle kokuvikela i-electromagnetic kwegwebu le-aluminium kuyehla bese kukhuphuka ngokwanda kwe-electromagnetic wave frequency. Embonini ye-aerospace, igwebu le-aluminium lisetshenziswa njengengxenye ekwenzeni izigaxa zesikhala noma izinjini zomoya, eziwusizo kakhulu ekwehliseni isisindo esiphelele sezingxenye zendiza ngenxa yesisindo esincane segwebu le-aluminium. Ngaphezu kwalokho, njengento enhle kakhulu emunca amandla, igwebu le-aluminium lisetshenziswa ekwenzeni izigcina-mkhathi zemikhumbi-mkhathi, izinto zokudlidliza kanye nephansi lama-capsules okubuyisela umkhumbi-mkhathi, okuvumela ukuhlala okuphephile futhi kuvikele osomkhathi nemishini yasemkhathini. Ngokumunca ngempumelelo amandla kanye nokudlidliza okudambisayo, igwebu le-aluminium lingaqinisekisa ukuphepha kosomkhathi uma kwenzeka kuba nomthelela wokuhlala komkhumbi-mkhathi.
Embonini yezimoto, i-aluminium foam isiza ukunciphisa inani eliphelele lezingxenye ezisetshenziswa kuhlaka, okwenza inqubo yomhlangano iphumelele, okusiza ekugcineni ukunciphisa izindleko nokuthuthukisa ukusebenza. Njengamanje, igwebu le-aluminium lisetshenziswa emigoqweni yokuphahlazeka, amalungu awelayo kanye nemishayo yeminyango ezakhiweni zemizimba yemoto emakethe.

(a) Umdwebo wezingxenye zasendaweni ezimunca amandla zomsebenzi womzimba. (b) Umdwebo wohlelo lwe-aluminiumigwebuibha yokuphahlazeka.

Embonini yezokwakha, ukusetshenziswa okuyinhloko kwei-aluminium foaminjengesivikelo, isithiyo esimelana nomlilo ngokumelene nomsindo omkhulu. Izibonelo ezijwayelekile zokusetshenziswa kwezakhiwo zegwebu le-aluminium yamaseli avaliwe yisiteshi saseLondon Underground kanye ne-SOHO Revival Square e-Shanghai, lapho abaklami basebenzise inani elikhulu legwebu le-aluminium ukuze limunce umsindo futhi lifakwe ngaphakathi.

(a) (b) Izithombe zegwebu le-aluminium elisetshenziswe ngaphakathi kwe-SOHO Plaza, e-Shanghai; (c) Igwebu le-Aluminium + udonga lwensimbi oluhlanganisa umsindo olumunca umsindo eSiteshini saseBermondsey, eLondon Underground.

3. Isiphetho
Ukutholakala kwegwebu le-aluminium kuthathwa njengempumelelo emangalisayo.I-aluminium foamimpahla ihlanganisa izindawo ezinhle kakhulu zokuvikela i-electromagnetic, isisindo esincane, ukuminyana okuphansi, ukuncibilika kokudlidliza kanye nezakhiwo zokumunca amandla, okwenza isebenze kabanzi ezimbonini ezahlukahlukene namuhla. Kuyathakazelisa ukuthi igwebu le-aluminium liphinde libe ngumkhiqizo ohambisana nemvelo ongaphinda usetshenziswe, okusho ukuthi iwumsebenzi osimeme okuthemba ukuthi uzosetshenziswa kwinani elikhulu lezicelo zezimboni esikhathini esizayo.
