Ibhulogi

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 ye-powder metallurgy. 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.

Amaphaneli amasemishi e-aluminium Foam aya ngokuya ethandwa kakhulu ezimbonini ezahlukahlukene ngenxa yezakhiwo zawo ezihlukile kanye nobubanzi bezicelo. Lawa maphaneli aqukethe into ewumgogodla engasindi (njengegwebu le-aluminium) ehlanganiswe phakathi kwamashidi amabili amancane e-aluminium. Lesi sakhiwo esisha senza izinto ezingasindi nje kuphela, kodwa futhi ziqine, ziqine futhi zimelane nokugqwala. Kule bhulogi, sizobhekisisa ukusetshenziswa nezinzuzo zamaphaneli wesemishi le-aluminium Foam, kanye nomthelela wawo ezimbonini ezahlukahlukene.

Njengamanje, iningi lomklamo olungile ukunciphisa isisindo somzimba ngaphandle kokunciphisa ukusebenza komzimba, esimweni esinikeziwe ukuthola indlela yokudlulisa engcono yomthwalo, ukuze uklame isakhiwo somzimba esingcono; Ngasikhathi sinye, inani elikhulu lezinto ezintsha kanye nobuchwepheshe obusha futhi kusiza ukunciphisa isisindo somzimba, bese, okulandelayo ndawonye ukuqonda izinzuzo nezinkinga zezinto ezivamile ezingasindi it!

I-Metal Foam ithola ukunakwa ezimbonini ezihlukahlukene ngenxa yezakhiwo zayo ezingasindi kanye namandla aphezulu. I-China Beihai Composites Co., Ltd. ingomunye wabakhiqizi abahamba phambili begwebu lensimbi futhi inkampani ihamba phambili ekukhiqizeni izinto ezintsha zokusetshenziswa okuhlukahlukene.

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

I-Metal Foam iya ngokuya ithandwa ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo eziyingqayizivele kanye nezicelo. Enye yezinto eziyinhloko ze-foam yensimbi yi-porosity yayo, edlala indima ebalulekile ekunqumeni izakhiwo zezinto ezibonakalayo kanye nokufaneleka kokusetshenziswa okuhlukile. Kule bhulogi, sizobhekisisa umqondo we-porosity kumagwebu ensimbi futhi sihlole ukuthi kusho ukuthini ekusetshenzisweni okuhlukahlukene.

Igwebu le-Copper lenza amagagasi kubuchwepheshe bebhethri ngenxa yezakhiwo zayo ezihlukile. Iyaziwa ngendawo yayo ephezulu kanye nokuhamba kahle kwe-thermal kanye nogesi, okuyenza ibe yinto ekahle yokusetshenziswa kwebhethri. Kodwa-ke, kusekhona ukudideka mayelana nezakhiwo zayo zokuqhuba nokuthi ingabe iyinto efanelekile yini ukusetshenziswa kumabhethri. Kule bhulogi, sizohlola izici ze-copper foam kanye neqhaza elingaba khona kubuchwepheshe bebhethri obuzayo.

Igwebu le-aluminium liyinto ethokozisayo eya ngokuya ithandwa kakhulu ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo ezihlukile kanye nohlu olubanzi lwezinzuzo. Kusukela ekubeni engasindi futhi uqine kuye kwezinhle kakhulu zokushiswa kwe-thermal kanye ne-acoustic, igwebu le-aluminium lifakazele ukuthi liyinto ebalulekile yezinhlelo zokusebenza eziningi. Kulesi sihloko, sizohlola izinzuzo zegwebu le-aluminium nokuthi lingayishintsha kanjani indlela esiklama ngayo futhi senze imikhiqizo eyahlukene.

Enye yezinkinga eziyinhloko ezizungeze igwebu le-copper yi-conductivity yayo, into eguquguqukayo futhi eguquguqukayo. Kule bhulogi, sizohlola izakhiwo ze-foam yethusi, izakhiwo zayo zokuqhuba, kanye nezinhlelo zokusebenza zayo ezihlukahlukene.
