I-Aluminiyamu enegwebu yakhiwa ngokwengeza izithasiselo ku-aluminium emsulwa noma ingxubevange ye-aluminium ngenqubo yokukhipha ugwebu, futhi inezici zombili zensimbi nezamabhamuza. Inokuminyana okuphansi, ikhono lokumunca ukushaqeka okuphezulu, ukumelana nokushisa okuphezulu, ukumelana nomlilo okuqinile, ukumelana nokugqwala, ukwahlukanisa umsindo nokuncishiswa komsindo, ukuguquguquka okuphansi kwe-thermal, ukuvikela okuphezulu kukagesi, ukumelana nesimo sezulu esinamandla, ikhono lokuhlunga, ukucubungula kalula, ukuyifaka kalula, kanye nokuphakama okuphezulu. ukwakha ukunemba , Ukugqoka okuphezulu kungenziwa.

I-Aluminium enegwebu uhlobo olusha lwensimbi elula ekhiqizwa i-aluminium alloy foaming. Inokuminyana okuphansi namandla athile aphezulu. Inezici eziningi ezinhle kakhulu njengokumuncwa komsindo kanye nokuvala umsindo, ukumunca amandla nokuwabamba, ukunqanda ilangabi kanye nokuvikela ukuqhuma. Isetshenziswa kabanzi ku-aerospace yezempi, ukuhamba kwezitimela, ukukhiqizwa kwemikhumbi, njll. Inkambu yemishini. Phakathi “Kwezinto Ezintsha Ezingase Ziphezulu Eziyishumi Ezinamandla Kakhulu Esikhathini Esizayo” ezikhethwe abezindaba bakwamanye amazwe, impahla yegwebu le-aluminium ikleliswe endaweni yesithupha.

Singakwazi ukwenza ngendlela oyifisayo amaphrofayili e-aluminium egwebu anezimbobo ezihlukahlukene, ubukhulu kanye nezidingo ngokuya ngezidingo zokuklama.

1. Izici zokusebenza

① I-Lightweight: Ukuminyana izikhathi ezingu-0.1-0.4 kune-aluminiyamu yensimbi;

② Ukuqina okukhethekile okuphakeme: ukuqina kwayo okuqondile okugobayo izikhathi ezingu-1.5 kunensimbi;

③ Ukusebenza kokumunca ukushaqeka okuphezulu okudambisa amandla kanye nezinga lokumunca amandla nomthelela:ukusebenza damping kuyinto5-10izikhathi kune-aluminium yensimbi. I-Porosity Uma igwebu le-aluminium elinezinga lama-84% lonakaliswa ngo-50%, lingamunca ngaphezu kuka-2.5MJ/cm3 wamandla.

④ Umsebenzi omuhle we-acoustic: 1. Ukusebenza kokufakwa komsindo (iseli elivaliwe): Umaimvamisa yegagasi lomsindo iphakathi kuka-800-4000HZ, I-coefficient yokufakwa komsindo yegwebu le-aluminium evaliwe ingaphezulu kuka-0.9. 2. Ukusebenza kokumuncwa komsindo (micro ngokusebenzisa izimbobo kanye nezimbobo): Uma imvamisa yegagasi lomsindo iphakathi kuka-125—4000HZ, i-coefficient ephezulu yokumunca umsindo yegwebu le-aluminium ephuma emgodini ingafinyelela ku-0.8, kanye nesilinganiso sokumuncwa kwe-coefficient yomsindo webhendi ye-octave idlula u-0.4.

⑤ Ukusebenza okuhle kakhulu kokuvikela i-electromagnetic: lapho i-electromagnetic wave frequency iphakathi kuka-2.6-18GHZ, i-electromagnetic, inani elivikelayo lingafinyelela ku-60-90dB.

⑥ Izakhiwo ezishisayo ezishisayo: I-thermal conductivity yegwebu le-aluminium yeseli elivaliwe eline-porosity engu-80-90% ngu-0.3-1W/m#8226;k, okulingana nemabula. Igwebu le-aluminium eliphuma emgodini linokusebenza okuhle kokukhipha ukushisa ngaphansi kwezimo zokuhambisa ngempoqo ngenxa yokuxhuma kwezimbotshana.

⑦ ayishi futhi ikwazi ukumelana nokushisa. □Ukumelana nokugqwala okuhle, ukumelana nesimo sezulu, ukumunca umswakama ophansi, akugugi, Akunabuthi.

⑧ Kulula ukucubungula: kulula ukusika, ukubhoboza, nokufaka usimende; ingagoba ibe yisimo esidingekayo ngokubunjwa; ingasebenzisa upende we-organic noma we-Inorganic usetshenziselwa ukwelashwa kwendawo; ingafakwa isikhumba ezinhlangothini zombili ukuze yenze ibhodi elikhulu elingasindi, eliqinile. Usayizi ojwayelekile wamanje: 600x1200x5/10MM, 500x1000x5/10MM.

⑨ Ukufaka kalula: Izinto ezinegwebu le-aluminium zingafakwa endaweni ephakeme ngaphandle kwemishini yokuphakamisa imishini, njengalezi: amashedi ophahleni, izindonga nophahla, njll., zingaxhunywa futhi zilungiswe ngezindlela zemishini noma ngokuqondile ngezikulufo, noma zingakwazi. kunamathiselwe odongeni noma ophahleni ngezinamatheliso.

⑩ Isakhiwo “sesemishi” esakhiwe ipuleti elincane lensimbi-i-aluminium foam-ipuleti lensimbi elincanyana lizuza ifa lezinto ezihlukile zegwebu le-aluminium namandla okugoba aphezulu, lingasetshenziswa njengezinto zokwakha ezintsha, izingxenye zesakhiwo eziqinile zesitoko, njll.

2. Izici zesakhiwo

• Imbobo enkulu ingu-0.3-7mm;
• I-porosity ephezulu futhi elawulekayo: 63%–90%;
• Indawo ethize ingu-10—45cm2/cm3;
• Isakhiwo samaseli ahlukene; iseli elivaliwe, ngeseli kanye ne-micro ngokusebenzisa i-cell aluminium foam;
• Ukubunjwa kanye nesakhiwo se-pore sohlaka lwensimbi luyalawuleka, olungakwazi ukuzivumelanisa nezidingo ezahlukene.

3. Ububanzi besicelo

Ukumuncwa komsindo kanye nezinto zokuvikela umsindo: i-aluminium enegwebu ingasetshenziselwa ukulawula umsindo wezinsimbi zokukhanya zasemadolobheni, imigwaqo emikhulu, imigudu engaphansi komhlaba, imishini yomshini, nokuthuthukiswa kwamakamelo okukhala, amahholo anemisebenzi eminingi neminye imiphumela yomsindo yasendlini. Igwebu le-aluminium elimunca umsindo linamathiselwe esakhiweni sikakhonkolo noma sensimbi futhi lakhiwe nhlangothi zombili zama-viaducts namalayili alula njengezindonga ezinkulu ezimunca umsindo, ezinganciphisa umsindo wethrafikhi yasemadolobheni. I-aluminium yokufaka umsindo enegwebu ingasetshenziselwa ukuhlukanisa umsindo emakamelweni ekhompyutha efektri, imishini nemishini, nezindawo zokwakha zangaphandle, futhi ixazulula imikhawulo eminingi yezinto ezisetshenziswa kabanzi ezimunca umsindo njengamanje njengoboya bengilazi ne-asbestos.

4. Izindawo zokufaka izicelo

i-aluminium enegwebu ingaklama izakhiwo ezidingekayo ezibanzi ngokushintsha ukuminyana kwayo kanye nokwakheka kwezimbotshana. Lokhu kukhanga kwale nto eyingqayizivele. Ngakho-ke, isetshenziswa kabanzi emikhakheni eminingi.
