Igwebu le-aluminium litholakala ngokuxuba i-aluminium alloy powder nento ehlukanisiwe ngesikhathi sokushisisa nokufakwa kwegesi. Inezici zesisindo sokukhanya, i-porosity ephezulu kanye nendawo ethile ephezulu. Inazo zombili izici zezinto zensimbi negwebu, futhi inokumelana nomthelela oqinile, amandla athile aphezulu, ukumelana nokushisa okuphezulu, ukumelana nomlilo okuqinile, futhi iphinde ibe nezindawo eziqinile zokuvikela i-electromagnetic kanye nokuhlunga. Namuhla, sizokwethula izinzuzo zokusebenza eziyisikhombisa zokuhlolwa kwegwebu le-aluminium ngokuningiliziwe.

1. Ukuhlolwa kwe-aluminium foam - ukuhlaziywa kokusebenza kwesakhiwo
Isici esikhulu sesakhiwo se-aluminium foam ukuthi inenani elikhulu lama-pores ngaphakathi, okwenza kube lula ngesisindo futhi kuphakame ngamandla athile. Ngenxa yalezi zici, igwebu le-aluminium liba isigcwalisi sesandwich esingcono kakhulu samaphaneli ayinhlanganisela yesangweji, ethuthukisa kakhulu imodi yokuguquguquka kwezinto eziyinhlanganisela ngaphansi komthwalo, ukuze ukumelana nokugoba kwayo, amandla okucindezela, namandla okumunca umsindo kuthuthukiswe. ukuthuthukiswa okusebenzayo. Uma kuqhathaniswa nempahla yesemishi yekhekheba lezinyosi, izinto ze-aluminium ezinegwebu zinciphisa ngempumelelo izindleko futhi zinqobe ubungozi be-anisotropy yezinto zesemishi lezinyosi.

2. Ukutholwa kwe-aluminium foam material - ukuhlaziywa kokusebenza kokumuncwa kwamandla
Inqubo isuka emandleni iye ekucindezelweni kwezinto zegwebu ihlukaniswe izigaba ezintathu, isigaba sokuqala yisiteji sokuguga nokunwebeka. Ngemuva kokucindezelwa, izimbotshana zangaphakathi ze-aluminium enegwebu zishintshashintsha futhi zibuyiseleke. Isigaba sesibili yisiteji sokubumba. Lapho amandla emishini yezinto ze-aluminium ezinegwebu efinyelela ezingeni elingabuyiseleki, lingena esiteji sokubumba. Ngalesi sikhathi, izimbotshana zangaphakathi ziba nokuguquguquka njengokugoqa nokukhasa, futhi ekugcineni zigoqe ngokuphelele. Lapho izinga lokuwa lifinyelela ukuxhumana phakathi kwezindonga zembobo eziphambene, lingena esigabeni sesithathu: isigaba sokuminyana. Ngakho-ke, ngemuva kokuthi igwebu le-aluminium lingaphansi kwengcindezi, libhekana nokuziphatha okuhlukile kokucindezela. Kule nqubo, ingcindezi iguqulwa ibe yikhono le-foam deformation, elithatha ngokuphumelelayo amandla omthelela wamandla.

3. Ukutholwa kwegwebu le-aluminium - ukuhlaziywa kokusebenza kokushaqeka kokumuncwa
I-aluminium enegwebu inezinto ezimanzi eziphakeme, izikhathi ezi-5 kuya kweziyi-10 kune-aluminium ehlanzekile. Lesi sici sihlobene ne-porosity, usayizi we-pore kanye ne-load-strain amplitude yegwebu le-aluminium ngokwayo. Ukuphakama kwe-porosity, usayizi wembobo ube mncane kanye nobukhulu be-load-strain amplitude, kungcono ukudambisa igwebu le-aluminium.

Lapho impahla ye-aluminium enegwebu ingaphansi kwengcindezi yangaphandle, ngenxa yama-pores angalingani, ukusatshalaliswa kwamandla obunzima nakho akulingani, ukuze amandla okucindezela ajwayelekile aguqulwe abe yingcindezi ye-shear, edla ukucindezeleka kwangaphandle futhi iguqule ibe amandla ashisayo ngaphakathi. impahla ye-aluminium enegwebu. Ngokwalesi sici se-aluminium enegwebu, impahla ye-aluminium enegwebu iba yinto enhle kakhulu edonsa ukushaqeka. Okufana nobhampa bezimoto, igiya lokuhlala lemikhumbi-mkhathi, njll.

4. Ukuhlolwa kwegwebu le-aluminium - ukuhlaziywa kokusebenza kokumuncwa komsindo
Isakhiwo esiyingqayizivele se-pore se-aluminium foam material siyenza ibe nokusebenza okuhle kokumuncwa komsindo. Lapho umsindo udlula embotsheni, kubangela ukunkenketha komsindo embotsheni, futhi ukungqubuzana nodonga lwembotshana kukhiqiza amandla okushisa, futhi amandla okushisa ahlakazeke nge-aluminium, ngakho ukwakheka kwembotshana ye-aluminium enegwebu ngokuphumelelayo. amunca umsindo. Ukusebenza komsindo kokumuncwa kwe-aluminium enegwebu kukhuphuka ngokwanda kwe-porosity, ukwehla kosayizi wembotshana kanye nokwanda kokuqina kwempahla. Ngokwezakhiwo zokumunca umsindo ze-aluminium foam, isetshenziswa kakhulu kuma-studio okurekhoda omsakazo kanye nemishini yehhovisi ezenzakalelayo.

5. Ukutholwa kwegwebu le-aluminium - ukuhlaziywa kokusebenza kokuvikela i-electromagnetic
Ucwaningo nokuhlola kukhombisa ukuthi impahla ye-aluminium enegwebu inokusebenza okuhle kokuvikela i-electromagnetic. Lapho inkambu kazibuthe enemvamisa ephezulu idlula kugwebu, inkambu yamanje kazibuthe ikhiqizwa ngaphakathi kwegwebu, ekhansela inkambu kazibuthe yasekuqaleni. Ngokwalokhu kusebenza, impahla ye-aluminium enegwebu isetshenziswa egumbini lemishini kagesi kanye nemishini kagesi,

Ezintweni zokuvikela zemishini kagesi.

6. Ukutholwa kwe-aluminium foam material - ukuhlaziywa kokushintshaniswa kokushisa nokusebenza kokushisa okushisayo
Ngenxa yokuthi impahla ye-aluminium foam iqukethe inani elikhulu lamabhamuza omoya anamandla amancane okudlulisa ukushisa, ukuqhutshwa kwayo okushisayo akuphakeme njenge-aluminium, kodwa kungcono kakhulu kunamapulasitiki anegwebu. I-conductivity yayo yokushisa ithinteka yi-porosity, futhi ukuphakama kwe-porosity, kubi kakhulu ukuqhutshwa kokushisa. Ngaphansi kwezimo zemvelo zokuhambisa, ukushisa kukhishwa ukushintshaniswa kokushisa phakathi kwegesi noma uketshezi kanye nezindonga zembobo. Lokhu kwenza igwebu le-aluminium libe ukushintshanisa okuhle kokushisa noma izinto zokulahla ukushisa. Isibonelo, idivayisi ye-deicing ifakwa phambi kwephiko lendiza, futhi igesi eshisayo noma i-antifreeze ikhishwa ezintweni ze-aluminium ezinegwebu ukuze kufezwe injongo yokukhipha.

7. Ukutholwa kwe-Aluminium Foam - ukuhlaziywa kokusebenza kokuhlunga
Ngenxa yokuqina kwegwebu le-aluminium, ingasetshenziswa njengesihlungi esihle emkhakheni wezinto eziphilayo namakhemikhali. Izimbotshana ezisentweni ye-aluminium foam zinomphumela omuhle wokuhlunga nokuhlukanisa kumagesi noma oketshezini, futhi zingasefa izinto eziqinile zomoya.
