Izinzuzo kanye nezakhiwo ze-Aluminium Foam

Ukuthuthukiswa kobuchwepheshe bezinqubo zesimanje kuye kwaholela ekuthuthukisweni okwandayo kobuchwepheshe bokulungiselela i-foam metal kanye nokwehliswa okuqhubekayo kwezindleko zokukhiqiza. Insimbi yegwebu emelwe ngui-aluminium foamwuhlobo olusha lwezinto ezisebenzayo zesakhiwo oluthuthukiswe ngokushesha eminyakeni yamuva. Njengempahla yesakhiwo, ibonakala ngesisindo esincane namandla athile aphezulu. Njengento esebenzayo, igwebu le-aluminium linezinzuzo zokumunca ukushaqeka, ikhono lokudonsa ukushaqeka, ukumelana nokushisa okuphezulu, ukuvala umsindo nokumuncwa komsindo.

Izimbotshana zangaphakathi zei-aluminium foam evaliwezigcwele amagesi anamandla amancane okudlulisa ukushisa, okwenza amandla awo okudlulisa ukushisa abe mancane kakhulu kunezinto eziqinile. Indawo enkulu ethize, i-porosity ephezulu, indawo ebanzi yokusabalalisa ukushisa kanye nokudluliswa kokushisa okuphezulu kodonga lwezimbotshana ze- through-cell foam aluminiyamu kuyinikeza ukusebenza okuhle kokushintshisana kokushisa. Ngaphansi kwesimo se-convection yemvelo, ukushintshaniswa kokushisa kungenziwa ngokugeleza kwegesi noma uketshezi ezimbotsheni zensimbi eyigwebu njengegwebu le-aluminium eliphumela ngaphandle kanye nodonga lwembotshana yalo, ngakho-ke igwebu le-aluminium eliphuma emgodini liwukushintshanisa okuhle kakhulu kokushisa. impahla noma impahla yokukhipha ukushisa.

Igwebu le-aluminium enqubweni yokucindezelwa lizoguqulwa libe inani elikhulu lomsebenzi ngendlela ye-aluminium foam cell deformation, ukuwa, ukuphuka nokungqubuzana okuhlangene nezinye izinhlobo zokulahlekelwa kwamandla, ngakho-ke igwebu lingakwazi ukumunca inani elikhulu lamandla omthelela wangaphandle.I-aluminium foaminezici zokumanzisa okuphezulu, inani lokudambisa igwebu le-aluminium elihlanzekile cishe liphindwe izikhathi ezi-5 kuya kweziyi-10 kune-aluminium. Ngokusebenzisa amandla amahle okumunca kanye nezakhiwo ezidambisayo zegwebu le-aluminium, ingenziwa ibe yizinto ezinhle kakhulu zokumunca amandla nezinto ezidambisa ukudlidliza, njengamabhampa ezimoto, amagiya okuhlalisa umkhumbi-mkhathi, amakheshi, amaphedi okuphepha okuthutha kanye nomugqa wejubane obamba amandla. .

Ngenxa yamandla okudlulisa uketshezi oluhle, ukusebenza kokukhipha ukushisa kwensimbi yegwebu ngembobo kungafinyelela ngisho nasekuphatheni okushisayo kwe-matrix yayo eminyene, futhi ukusetshenziswa kwale nsimbi yegwebu kungathuthukisa amandla okushintshanisa ukushisa kwezishintshisi zokushisa zemishini yasemkhathini, osinki bokushisa abahlangene bamandla wamandla, nemibhoshongo yokupholisa umoya. Isibonelo, kumadivayisi avimbela ukuqhwa kanye nama-anti-frizing asetshenziswa endizeni,amaphaneli e-aluminium foam ngokusebenzisa imbobozifakwe phambi kwamaphiko, futhi igesi eshisayo noma i-antifreeze ingafuthwa ngaphandle kwamaphaneli e-aluminium foam ukuze kuzuzwe inhloso yokunqanda ukuqhwala.
