Tiyeni tiphunzire za katundu ndi ntchito za aluminiyamu pamodzi

1. Kuchuluka kwa aluminiyumu ndi kochepa kwambiri, kokha 2.7g / cm. Ngakhale kuti ndi yofewa, imatha kupangidwa mosiyanasiyanazitsulo za aluminiyamu, monga aluminiyamu yolimba, aluminiyumu yolimba kwambiri, aluminiyamu yotsimikizira dzimbiri, aluminiyamu yotayidwa, ndi zina zotero. Ma aluminiyamu opangidwa ndi aluminiyumu amagwiritsidwa ntchito kwambiri m'makampani opanga ndege, magalimoto, sitima, ndi zombo. Kuphatikiza apo, ma roketi amlengalenga, ma satellites, ndi ma satellites ochita kupanga amagwiritsanso ntchito kuchuluka kwa aluminiyamu ndi ma aloyi ake. Mwachitsanzo, ndege yapamwamba kwambiri imakhala ndi pafupifupi 70% ya aluminiyamu ndi ma aloyi ake. Aluminiyamu imagwiritsidwanso ntchito kwambiri popanga zombo, ndipo sitima yayikulu yonyamula anthu nthawi zambiri imadya matani masauzande angapo a aluminiyamu.

2. The conductivity ya aluminiyamu ndi yachiwiri kwa siliva ndi mkuwa. Ngakhale kuti conductivity yake ndi 2/3 yokha yamkuwa, kachulukidwe kake ndi 1/3 chabe yamkuwa. Choncho, ponyamula magetsi ofanana, ubwino wa waya wa aluminiyamu ndi theka la waya wamkuwa. Filimu ya oxide yomwe ili pamwamba pa aluminiyumu sikuti imatha kukana dzimbiri, komanso imakhala ndi mlingo winawake wa kusungunula, kotero kuti aluminiyumu imakhala ndi ntchito zambiri m'makampani opanga magetsi, mafakitale a waya ndi chingwe, ndi mafakitale opanda waya.

 
3. Aluminiyamu ndi conductor wabwino wa kutentha, ndi matenthedwe conductivity katatu kuposa chitsulo. M'makampani, aluminiyamu imatha kugwiritsidwa ntchito kupanga zosinthira kutentha zosiyanasiyana, zida zoziziritsira kutentha, ndi ziwiya zophikira.

 
4. Aluminiyamu imakhala ndi ductility yabwino (yachiwiri kwa golide ndi siliva), ndipo imatha kupangidwa kukhala zojambulazo za aluminiyumu zowonda kuposa 0.01mm pa kutentha pakati pa 100 ℃ ndi 150 ℃. Zojambula za aluminiyamuzi zimagwiritsidwa ntchito kwambiri kuyika ndudu, masiwiti, ndi zina zotero. Zitha kupangidwanso kukhala mawaya a aluminiyamu, timizere ta aluminiyamu, ndi kukulungidwa muzinthu zosiyanasiyana za aluminiyamu.

 
5. Pamwamba pa aluminiyumu sawonongeka mosavuta chifukwa cha filimu yake yoteteza oxide, ndipo nthawi zambiri imagwiritsidwa ntchito popanga makina opangira mankhwala, zipangizo zamankhwala, zipangizo zafriji, zida zoyenga mafuta, mapaipi amafuta ndi gasi, ndi zina zotero.

 
6. Aluminiyamu ufa ali ndi siliva woyera luster (kawirikawiri mtundu wa zitsulo mu mawonekedwe ufa kwambiri wakuda), ndipo amagwiritsidwa ntchito ngati ❖ kuyanika, amene amadziwika kuti siliva ufa kapena siliva utoto, kuteteza zitsulo zopangidwa dzimbiri ndi kuonjezera awo. maonekedwe.

 
7. Aluminiyamu imatha kutulutsa kutentha kwakukulu ndi kuwala konyezimira ikatenthedwa ndi mpweya, ndipo imagwiritsidwa ntchito popanga zosakaniza zophulika, monga zophulika za ammonium aluminium (zopangidwa ndi osakaniza ammonium nitrate, ufa wamakala, ufa wa aluminiyamu, utsi wakuda) ndi zinthu zina zoyaka moto), zosakaniza zoyaka (monga mabomba ndi zipolopolo zopangidwa ndi aluminiyamu thermite zomwe zingagwiritsidwe ntchito polimbana ndi mipherezero yovuta kapena akasinja, mizinga, ndi zina), ndi zosakaniza zowunikira (monga barium nitrate 68%, aluminiyamu ufa 28%, ndi guluu tizilombo 4%).

 
8. Aluminiyamu thermite amagwiritsidwa ntchito kwambiri kusungunula zitsulo refractory ndi kuwotcherera zitsulo njanji. Aluminium imagwiritsidwanso ntchito ngati deoxidizer popanga zitsulo. Aluminiyamu ufa, graphite, titaniyamu woipa (kapena mkulu kusungunuka zitsulo oxides) ndi uniformly kusakaniza mu chiŵerengero china ndi yokutidwa pa chitsulo. Pambuyo powerengera kutentha kwambiri, zida zachitsulo zosagwira kutentha kwambiri zimapangidwa, zomwe zimakhala ndi ntchito zofunika kwambiri muukadaulo wa rocket ndi missile.

 
9. Mbale ya aluminiyamu imakhalanso ndi ntchito yabwino yowonetsera kuwala, yowonetsera kuwala kwa ultraviolet kulimba kuposa siliva. Aluminiyamu yoyera kwambiri, imapangitsanso luso lake lowonetsera bwino. Choncho, nthawi zambiri amagwiritsidwa ntchito popanga zowunikira zapamwamba kwambiri, monga zowonetsera chitofu cha dzuwa.

10. Aluminiyamu imakhala ndi mphamvu zomveka bwino komanso zomveka bwino, choncho denga m'zipinda zoulutsira mawu ndi nyumba zazikulu zamakono zimapangidwanso ndi aluminiyumu.

 
11. Kutsika kwa kutentha kwapansi: Aluminiyamu yawonjezera mphamvu popanda brittleness pa kutentha kochepa, ndikupangitsa kuti ikhale yabwino kwa zipangizo zotsika kutentha monga firiji, mafiriji, magalimoto a chipale chofewa ku Antarctic, ndi zipangizo zopangira hydrogen oxide.

 
12. Ndi amphoteric oxide
