1. Kodi Foamed Metal ndi Foamed Aluminium ndi chiyani
M'mbiri yakale, kupezeka kwa zitsulo zopangidwa ndi thovu ndi chinthu chofunika kwambiri pakusintha kwa ntchito yonse ya uinjiniya wa zinthu. Chithovu chachitsulo ndi chinthu chomwe chimakhala ndi chitsulo chokhala ndi ma pores ambiri omwe amadzazidwa ndi mpweya pamodzi ndi kapangidwe kake. Ma pores a zitsulo zachitsulo izi amatha kukhala ngati kulumikizana kapena zisindikizo za hermetic, zomwe zimadziwika kuti ma cell otseguka komanso ma cell otsekedwa, motsatana. Mwa iwo,aluminium thovupakali pano ndi chitsulo cha thovu chomwe chili ndi kuthekera kwakukulu kogwiritsa ntchito, ndipo chimadziwika kuti "metal star" chifukwa cha zinthu zingapo zabwino kwambiri, monga porosity yayikulu, kachulukidwe kakang'ono, kulemera kopepuka, mphamvu yayikulu, kuponderezana kwabwino, kuyamwa bwino, mayamwidwe abwino amawu, komanso chitetezo chamagetsi. "Nyenyezi yachitsulo", yomwe imagwiritsidwa ntchito kwambiri muumisiri wamlengalenga, kupanga ndi njira zina zogwirira ntchito zasayansi.

Mawonekedwe apangidwe a thovu la aluminiyamu: (a) Chithovu cha aluminium chotseguka; (b) Chithovu cha aluminiyamu chotsekedwa

2. Katundu ndi Ntchito zaAluminium Foam
Chithovu cha aluminiyamu ndi chitsulo chokhala ndi porosity yapamwamba komanso mapangidwe a porous, momwe ma pores osindikizidwa amawerengera pafupifupi magawo atatu mwa magawo atatu a chiwerengero chonse cha zitsulo zachitsulo, zomwe zimapangitsa kuti zinthuzo zikhale zopepuka kwambiri. Kuphatikiza pa zinthu izi, chithovu cha aluminiyamu chimakhala ndi mphamvu zoyamwitsa mphamvu komanso kupsinjika kwambiri. Pankhani ya kachulukidwe, ofufuzawo adapeza kuti zitsanzo zambiri za aluminium thovu zimakhala ndi kachulukidwe kozungulira 0.4-1.2 g-cm-3. Kuphatikiza apo, chithovu cha aluminiyamu chimakomera mawu, chimatha kugwiritsidwanso ntchito komanso chimakhala ndi matenthedwe otsika.

Kupititsa patsogolo mawonekedwe osagwirizana ndi bilge: 1 - khungu lapamwamba; 2 -aluminiyamuthumba la thovu; 3 - m'munsi khungu

Pankhani ya ntchito, chitetezo chamagetsi, chopepuka komanso choyamwa cha aluminiyamu chimapangitsa kuti ikhale yoyenera pazida zomwe zimagwiritsidwa ntchito pazida zophatikizika, zamagalimoto, zakuthambo ndi mafakitale omanga chifukwa chotha kukana malo owopsa. Pazida zoyendetsedwa zophatikizika, thovu lotsekeka la aluminiyamu ndi chinthu chabwino kwambiri chotchingira ma elekitirodi. Chifukwa cha kulumikizidwa kwa mafupa a aluminium thovu, omwe ali ndi malo akuluakulu enieni komanso amatha kuyamwa ndikuwonetsa mafunde amagetsi, zotayika zosiyanasiyana, monga kutayika kwa mayamwidwe ndi kutayika kowunikira, zimachitika mu thovu la aluminium, lomwe limapatsa mphamvu. foam aluminiyamu zabwino kwambiri zamagetsi zamagetsi zoteteza. Ndipo zapezekanso kuti mphamvu yama electromagnetic shielding ya aluminium thovu ikucheperachepera kenako ndikuwonjezeka ndi kuchuluka kwa ma frequency a electromagnetic wave. M'makampani opanga ndege, chithovu cha aluminiyamu chimagwiritsidwa ntchito ngati chigawo chopanga ma cones kapena ma turbines, omwe amathandiza kwambiri kuchepetsa kulemera kwa zigawo zonse za ndege chifukwa cha kutsika kwa thovu la aluminiyumu. Kuphatikiza apo, monga chinthu chabwino kwambiri chotengera mphamvu, chithovu cha aluminiyamu chimagwiritsidwa ntchito popanga zotchingira m'mlengalenga, zotengera kugwedera ndi pansi pa makapisozi obwerera m'mlengalenga, zomwe zimathandiza kutera motetezeka ndikuteteza oyenda mumlengalenga ndi zida zakuthambo. Potengera mphamvu ndi kugwedera konyowa, thovu la aluminiyamu limatha kutsimikizira chitetezo cha oyenda m'mlengalenga ngati chombo cham'mlengalenga chikatera.
M'makampani opanga magalimoto, thovu la aluminiyamu limathandizira kuchepetsa kuchuluka kwa magawo omwe amagwiritsidwa ntchito mu chimango, kupangitsa kuti msonkhano ukhale wogwira mtima, womwe umathandizira kuchepetsa ndalama ndikuwongolera magwiridwe antchito. Pakadali pano, thovu la aluminiyamu limagwiritsidwa ntchito m'mipiringidzo yangozi, mamembala amtanda ndi matabwa a zitseko m'magulu amgalimoto pamsika.

(a) Chithunzi cha zigawo zomwe zimatengera mphamvu zamagulu amthupi. (b) Chithunzi chojambula cha aluminiyamuthovubala lakugwa.

Mu zomangamanga, ntchito yaikulu yaaluminium thovuali ngati chotchinga chotchinga moto motsutsana ndi phokoso lalikulu. Zitsanzo zodziwika bwino zamapangidwe a thovu lotsekeka la aluminiyamu ndi siteshoni ya London Underground ndi SOHO Revival Square ku Shanghai, komwe okonzawo adagwiritsa ntchito thovu la aluminiyamu yochulukirapo pakuyamwa ndi kutsekereza mawu.

(a) (b) Zithunzi za thovu la aluminiyamu lomwe limagwiritsidwa ntchito mkati mwa SOHO Plaza, Shanghai; (c) Chithovu cha aluminiyamu + zitsulo zachitsulo zomwe zimakhala ndi khoma lotulutsa mawu ku Bermondsey Station, London Underground.

3. Mapeto
Kupezeka kwa thovu la aluminiyamu kumaonedwa kuti ndi kupambana kodabwitsa.Chithovu cha AluminiumZinthu zimaphatikiza zida zabwino kwambiri zotchingira ma elekitiroma, kulemera kopepuka, kachulukidwe kakang'ono, kugwedera ndikuyamwa mphamvu, zomwe zimapangitsa kuti zizigwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana masiku ano. Chosangalatsa ndichakuti, thovu la aluminiyamu ndi chinthu chokonda zachilengedwe chomwe chimatha kubwezeretsedwanso, kutanthauza kuti ndi chinthu chokhazikika chomwe chikuyembekezeka kugwiritsidwa ntchito pamafakitale ambiri mtsogolomo.
