Ibhulogi yomkhiqizo

Ukuncipha kwezibaseli ezimbiwa phansi kanye nokukhathazeka okukhulayo mayelana nezindaba zamandla nemvelo kuye kwaholela emizamweni eminingi yocwaningo yokuthuthukisa eminye imithombo yamandla. I-electrochemical electrolysis yamanzi ithathwa njengesu elithembisayo lokukhiqizwa kukaphethiloli we-hydrogen.

Enkathini yokuxhumana okungenantambo okuya ngokuya kubi kakhulu kanye nokungcoliswa kazibuthe, isidingo sezinto ezisebenzayo zokumunca amagagasi kagesi sesibaluleke kakhulu kunangaphambili. I-Metal Foam, njengento entsha, ibonisa amandla amakhulu kulo mkhakha. Ucwaningo lwakamuva lugxile ekuhloleni amandla kazibuthe wegagasi lokumunca amagwebu ensimbi, futhi imiphumela iyamangalisa.

Emphakathini wanamuhla, sibheka umgoqo ozwakalayo lo mkhiqizo uyanda, ama-workshops, izibhedlela, izikole, amahhovisi okuphatha umgwaqo omkhulu, njalonjalo isidingo sokunciphisa umsindo, ngesikhathi sokubonisana nawo, umbuzo obuzwa kakhulu uthi: kanjani okuningi lokhu kungancishiswa. Manje sizokwabelana nawe ngomgomo wokunciphisa umsindo wesithiyo somsindo.

Igwebu le-Aluminium liyinto esebenza kahle kakhulu engasindi, esetshenziswa kabanzi ekwakhiweni kwezimoto, ekuhlobiseni ukwakha neminye imikhakha. Ukuze ukhiqize i-aluminium foam, udinga ukusebenzisa uchungechunge lwemishini, okuhlanganisa ukucubungula, ukugwedla, ukomisa nezinye izinqubo. Lapho usebenzisa lezi zisetshenziswa, naka ukuphepha, lungisa futhi ugcine izinto zokusebenza ngokuya ngemiyalelo ukuze uqinisekise ikhwalithi yokukhiqiza nokusebenza kahle kwegwebu le-aluminium.

Igwebu le-aluminium lifana nokuma kwesipontshi futhi laziwa njengensimbi yendawo yonke, enesisindo esiphansi nesisindo esincane, esetshenziswa njengesendlalelo sokuvikela izimoto zasemkhathini, imelana nokucindezelwa futhi ekwazi ukumelana nemisebe kagesi ebangelwa yimisebe. Kuyinto entsha yensimbi eyenziwe nge-foamed aluminium alloy.

Njengezinto zokuvikela ezimunca amandla ezisetshenziswa kabanzi, ukusetshenziswa kwamaphaneli e-aluminium foam sandwich (AFS) kusalokhu kuvinjelwa izici zemishini eziphansi ze-foam core. Ukufakwa kwe-coppercoated carbon fibers (Cf) kufakazele ukuthi kuphumelela ekuthuthukiseni izakhiwo zemishini yegwebu le-aluminium.

Kodwa-ke, ukuqonda inqubo yayo yokukhipha amagwebu kanye ne-microstructure kusenomkhawulo. Kulo msebenzi, i-AFS kanye ne-Cf/AFS zakhiwe ngendlela yokupakisha eyimpuphu yensimbi. Ukuziphatha okunegwebu kwe-AFS kanye ne-Cf/AFS phakathi namazinga okushisa aphakeme kwabonwa kusetshenziswa ubuchwepheshe bokuthwebula be-X-ray ngemisebe ye-synchrotron ukuze kuphenywe umthelela we-Cf kuma-bubble nucleation, ukukhula, kanye nokuzinza kwegwebu. Ngaphezu kwalokho, ukusatshalaliswa kosayizi wembotshana we-macroscopic, i-microscopic microstructure, kanye nezakhiwo zemishini ezicindezelayo ze-AFS kanye ne-Cf/AFS zahlaziywa. Imiphumela yabonisa ukuthi ukuba khona kwe-Cf kwandisa kakhulu izinga le-nucleation, kuthuthukisa ukuzinza kwamagwebu, futhi kuvimbela ukwakheka kwamabhamuza amakhulu ngokungavamile ngesikhathi sokuqala kwe-nucleation kanye nenqubo yokukhula. Phakathi naleso sikhathi, i-Cf/AFS ibonise amadayimitha embotshana acolekile kanye nokukhubazeka okumbalwa kune-AFS. Ukusatshalaliswa kwe-Cf ngokumanzisa okuhle kakhulu odongeni lwembotshana kuvimbele ukugqashuka kwefilimu ewuketshezi kanye nokuncipha kokuhlangana. Ukuhlolwa kokucindezelwa kubonise ukuthi, uma kuqhathaniswa ne-AFS, amandla okucindezela namandla okumunca amandla e-Cf/AFS anyuke cishe ngo-40.6% no-84.8%, ngokulandelana.

Igwebu lensimbi liyi-metallic material enezakhiwo ezikhethekile, ezinezinto zombili zensimbi negwebu, yingakho kuthiwa igwebu lensimbi. Ngakho, ingabe igwebu lensimbi liyinsimbi?

Uyalazi igwebu le-aluminium? Le nto emisha idala isiyaluyalu ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo ezingasindi futhi eziguquguqukayo. Kule bhulogi, sizobhekisisa izinhlobo ezahlukene zegwebu le-aluminium futhi sihlole uhla lwazo olubanzi lwezinhlelo zokusebenza.
