Basic katundu wa aluminiyamu

Aluminiyamu ndi chitsulo chachitsulo ndi chitsulo choyera chasiliva chomwe chimakhala chosavuta kusungunuka.Zogulitsa nthawi zambiri zimapangidwa kukhala ndodo, mapepala, zojambulazo, ufa, maliboni ndi ulusi.Mu mpweya wonyowa, imatha kupanga filimu ya oxide yomwe imalepheretsa dzimbiri zachitsulo.Aluminiyamu ufa ukhoza kuyaka mwamphamvu ukatenthedwa mumlengalenga, ndipo umatulutsa kuwala kowala koyera.Kusungunuka mu dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide ndi potaziyamu hydroxide solution, osasungunuka m'madzi.Kuchulukana kwachibale 2.70.Malo osungunuka 660 ℃.Malo otentha 2327 ℃.Aluminiyamu yomwe ili m'nthaka ya dziko lapansi ndi yachiwiri pambuyo pa okosijeni ndi silicon, yomwe ili pamalo achitatu, ndipo ndi chinthu chachitsulo chochuluka kwambiri padziko lapansi.Kukula kwa mafakitale atatu ofunikira oyendetsa ndege, zomangamanga ndi magalimoto kumafuna kuti zinthu zakuthupi zikhale ndi zida zapadera za aluminiyamu ndi ma aloyi ake, zomwe zimathandizira kwambiri kupanga ndi kugwiritsa ntchito aluminiyumu yatsopanoyi.Ntchito ndi yotakata kwambiri.

01. Kulemera kopepuka, mphamvu yeniyeni yeniyeni ndi kukana kwa dzimbiri kwa aluminiyumu ndizopadera kwambiri za ntchito yake.Aluminiyamu imakhala ndi kachulukidwe kakang'ono kwambiri ka 2.7 g/cm yokha

Ngakhale kuti ndi yofewa, imatha kupangidwa kukhala zotayidwa zosiyanasiyana zotayidwa, monga aluminiyamu yolimba, aluminiyamu yolimba kwambiri, aluminiyamu yotsimikizira dzimbiri, aluminiyamu yotayidwa, ndi zina zotero. Zotayidwazi zimagwiritsidwa ntchito kwambiri mu ndege, galimoto, sitima, sitima ndi zina. mafakitale opanga.Kuphatikiza apo, ma roketi a mumlengalenga, zotengera zakuthambo, ndi masetilaiti ochita kupanga amagwiritsanso ntchito aluminiyamu yochuluka ndi ma aloyi ake a aluminiyamu.

02. Mphamvu yeniyeni ya aluminiyumu alloy ndi apamwamba

03. Kukana kwa dzimbiri bwino

Aluminiyamu ndi chitsulo chosunthika kwambiri, koma ndi chokhazikika m'malo ambiri oxidizing.Uku ndiko kupanga filimu ya okusayidi pamwamba pa aluminiyumu mu mpweya, mpweya ndi zina zowonjezera.Filimu ya aluminium oxide sikuti imangokhala ndi kukana kwamphamvu kwa dzimbiri, komanso imakhala ndi mulingo wina wa kutchinjiriza.

04. The conductivity ya aluminiyamu ndi yachiwiri kwa siliva, mkuwa ndi golidi

Ngakhale kuti conductivity yake ndi 2/3 yokha yamkuwa, kachulukidwe kake ndi 1/3 chabe yamkuwa, kotero kuti apereke mphamvu yofanana ya magetsi, ubwino wa waya wa aluminiyamu ndi theka la waya wamkuwa.Chifukwa chake, aluminiyumu imakhala ndi ntchito zambiri m'makampani opanga zida zamagetsi, makampani opanga mawaya ndi chingwe komanso makampani opanga mawayilesi.

05. Aluminiyamu ndi conductor wabwino wa kutentha

Kutentha kwake kumakhala kokulirapo katatu kuposa chitsulo komanso nthawi 10 kuposa chitsulo chosapanga dzimbiri.Aluminiyamu imatha kugwiritsidwa ntchito m'makampani kupanga zosinthira kutentha zosiyanasiyana, zida zotayira kutentha ndi ziwiya zophikira.

06. Aluminiyamu ali ndi ductility wabwino

Ndi yachiwiri kwa golidi ndi siliva mu ductility ndipo imatha kupangidwa kukhala zojambula zoonda kuposa 0.006 mm.Zojambulazo za aluminiyamu zimagwiritsidwa ntchito kwambiri kunyamula ndudu, maswiti, ndi zina zotero. Angathenso kupangidwa kukhala mawaya a aluminiyamu ndi mizere, kutulutsa muzinthu zosiyanasiyana zooneka ngati zapadera, ndipo amatha kukulungidwa muzinthu zosiyanasiyana za aluminiyamu.Aluminiyamu imatha kudulidwa, kubowoleza ndi kuwotcherera ndi njira wamba.

07. Aluminiyamu si maginito

Sichimapanga maginito owonjezera ndipo sichimasokoneza zida zolondola.

08. Aluminiyamu imakhala ndi mphamvu zomveka bwino, ndipo phokoso la phokoso limakhalanso bwino

Chifukwa chake, aluminiyumu imagwiritsidwanso ntchito padenga m'zipinda zowulutsa komanso nyumba zamakono zazikulu.
