1. Zofunikira zolankhula:
Mayamwidwe a phokoso: mbale ya aluminiyamu ya thovu yotsekedwa imatha kupindika kuti ipangitse phokoso lokhala ndi mayamwidwe apamwamba kwambiri. Pamene mlingo wotsegulira ndi 1% ~ 3%, phokoso la mayamwidwe ndilopamwamba kwambiri. Mayamwidwe a phokoso amayezedwa ndi njira yoyimirira ya mafunde ali mumtundu wa 1000Hz mpaka 2000Hz, ndipo mayamwidwe amawu amafika 40% mpaka 80%.
Phokoso lamphamvu la aluminiyamu ya thovu: bolodi yotchinjiriza yopangidwa ndi sangweji ya aluminium thovu, 20mm wandiweyani, kutchinjiriza kwamawu: 20 ~ 40dB.
2. Kukana kwanyengo:
Kulimbana ndi dzimbiri: Kukumana ndi mlengalenga wanyanja kwa chaka chimodzi, palibe vuto lodziwikiratu; pakakhala dzimbiri, kuyezetsa kutsitsi kwa madzi kulibe vuto kwa zaka ziwiri; zikuwonetsa kuti kukana kwa dzimbiri kwa aluminiyamu ya thovu ndikwabwino kwambiri.
Palibe mayamwidwe a chinyezi: Kuchuluka kwa chinyezi cha aluminiyamu ya thovu ndi 0.0%. Palibe mayamwidwe a chinyezi, ndipo palibe kuwonongeka kwa machitidwe amawu chifukwa cha chinyezi.
Zinthu zosagwira kutentha / zosayaka: Aluminiyamu ya thovu imafewetsa pa kutentha kwakukulu kwa 600 ° C, ndipo ndi chinthu chosayaka.
Kuchita kwa insulation: Thermal conductivity of foamed aluminium ndi 0.25~0.62W/mK, yomwe ndi yofanana ndi ya marble, ndipo imakhala ndi ntchito yabwino yotsekera.
Kukhazikika kwamafuta: Chowonjezera chowonjezera cha aluminiyamu ya thovu ndi 1.934 * 10 ℃, yomwe ndi yofanana ndi konkriti, ndipo sikophweka kupundutsidwa ndi kutentha.
3. Mphamvu zamakina:
Mphamvu zamakina: mphamvu yopondereza: 3 mpaka 17 MPa; flexural mphamvu: 3 mpaka 15 MPa; mphamvu yamphamvu: 2 mpaka 7 MPa;
Kugwira ntchito mokhotakhota: Mayamwidwe amphamvu amatha kufikira 8J/cm3 ~ 30J/cm3, ndipo aluminiyamu yokhala ndi thovu imatha kuyamwa mphamvu kudzera pakupindika, komwe kumakhudza kwambiri mphamvu zoyamwa.
4. Kuchita kwa Machining:
Chithovu cha Aluminium chimagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana. Ndi porous, kuwala ndi siliva-zoyera zitsulo zakuthupi ndi makhalidwe abwino pokonza mosavuta. Itha kuchekedwa, kudula, kukonzedwa, kugayidwa, ndi zina zambiri, ndipo imatha kusinthidwa kukhala mbale ndi mizere. Mabala ndi mbali zosiyanasiyana zooneka mwapadera.
5. Chitetezo cha chilengedwe chobiriwira:
Zopanda poizoni: Chithovu cha aluminiyamu ndi chinthu chophatikizika chopangidwa ndi chitsulo ndi pores, chomwe chilibe poizoni ndipo sichingathawe mpweya wapoizoni pakatentha kwambiri.
Zobwezerezedwanso: Zida zazikulu zamakina a aluminiyamu thovu ndi ma aluminiyamu aloyi ndi ma oxide ake, omwe amatha 100% kubwezerezedwanso popanda kuwononga chilengedwe.
Electromagnetic shielding: Electromagnetic shielding (pansi pa 200MHz) yotchinga ma elekitiromagineti yotchinga 90dB, yokhala ndi ntchito yabwino kwambiri yamagetsi yamagetsi.
6. Minda yogwiritsira ntchito mankhwala
Chifukwa cha katundu wake wapadera, zotayidwa thovu zopangidwa angagwiritsidwe ntchito kwambiri muzamlengalenga, ndege, masitima othamanga kwambiri, sitima zapamtunda zamatawuni, zomanga zombo, njanji zothamanga kwambiri, zomanga, ngalande ndi zotchinga zomveka panjira. kugwedezeka, kuyamwa kwakukulu kwa mphamvu yamphamvu, kutetezedwa kwamphamvu kwamagetsi, kutsekereza kwambiri kutentha, kukana kutentha kwambiri, kukana moto komanso kusayaka. Ili ndi chilengedwe mwapadera.
Kuchita damping: Kuyesedwa ndi Institute of Solid State Physics, Chinese Academy of Sciences, mkati mwa friction factor Q-1 ya thovu aluminiyamu imafika 6 × 10-3.
