Kutsekeka kwa ma cell otsekedwa komanso kutsekereza mawu kwa Aluminium Foam block
1.Zomwe zimapangidwira.
Aluminiyamu thovu gulu: 97% aluminiyamu ufa, 3% thovu wothandizira, 1% TiH2
Kuchulukitsa viscose, 2% Ca. Iwo ndi chilengedwe chitetezo element alibe kuipitsa.
| Chidziwitso cha magwiridwe antchito (Pure Aluminium) | |||
| Kuchulukana(g/cm³) | Compressive Mphamvu(Mpa) | Kupindika Mphamvu(Mpa) | Mphamvu mayamwidwe(KJ/M³) |
| 0.25-0.30 | 3.0-4.0 | 3.0-5.0 | 1000-2000 |
| 0.30-0.40 | 4.0-7.0 | 5.0-9.0 | 2000-3000 |
| 0.40-0.50 | 7.0-11.5 | 9.0-13.5 | 3000 ~ 5000 |
| 0.50-0.60 | 11.5-15.0 | 13.5-18.5 | 5000 ~ 7000 |
| 0.60-0.70 | 15.0-19.0 | 18.5-22.0 | 7000 ~ 9000 |
| 0.70-0.80 | 19.0-21.5 | 22.0-25.0 | 9000 ~ 12000 |
| 0.80-0.85 | 21.5-32.0 | 25.0-36.0 | 12000 ~ 15000 |
2.Makhalidwe amagetsi a zipangizo.
Ma conductivity a aluminium thovu ndi ochepa kwambiri kuposa a aluminiyamu olimba.
Matenthedwe amtundu wa aluminium thovu ndi ochepa kwambiri kuposa aluminiyamu yolimba, yomwe ili pafupifupi 0.1 - 0.2 nthawi za aluminiyumu yolimba.
Kuphatikiza apo, aluminiyamu ya thovu ilinso ndi olimba, osayaka, osakhala opepuka makutidwe ndi okosijeni, osavuta kutulutsa ukalamba, kukana kwanyengo yabwino,kuchira bwino ndi kubadwanso kwatsopano.
Kuchita bwino kwambiri kwachitetezo chamagetsi: pomwe ma frequency a electromagnetic wave ndi 2.6-18GHZ,
mphamvu yamagetsi yotchinga ya aluminium thovu imatha kufika 60-90dB.
3.Corrosive makhalidwe zipangizo.
Kukana kwa dzimbiri: m'malo amlengalenga am'madzi am'madzi kwa chaka chimodzi, palibe vuto lodziwikiratu:
inapita patsogolo dzimbiri, madzi mchere kuyesera kuyesera kwa zaka 2 popanda kupatula.
Kuchita kupopera mbewu mankhwalawa odana ndi dzimbiri pamwamba mankhwala, kuonjezera kukana dzimbiri.
4.Acoustic makhalidwe.
20-40dB
5.Makhalidwe ogwedezeka.
Mayamwidwe amphamvu amphamvu yamphamvu, mphamvu zamagetsi zimatha kufika kupitilira 50%, nsanja yamagetsi yamagetsi ya 80% mpaka 90%, imatha kuyamwa bwino mphamvu zakunja, kuchepetsa kuwononga.
Foam aluminiyamu damping makamaka imatanthawuza kuyamwa kwake kwamphamvu kwamphamvu kapena mphamvu yamphamvu. Mayamwidwe owopsa kapena kukana kwamphamvu ndikofunikira kwambiri pakunyamula magalimoto. Aluminiyamu ya thovu ndi yabwino kuposa zida zina za thovu kuti zizitha kuyamwa mphamvu yamphamvu, ndi isotropic pakuchita, ndiye chinthu choyenera kusunga.
High damping ntchito ndi mphamvu mphamvu mayamwidwe mlingo: damping mphamvu zitsulo zotayidwa 5-10 nthawi.
Chithovu cha aluminiyamu chokhala ndi porosity ya 50% chimatha kuyamwa mphamvu zoposa 2.5MJ/M3C pamene chili ndi 84%.
Dulani m'mphepete mosakhazikika molunjika.
Dulani mu makulidwe ofunikira makasitomala kuti mupange thovu la aluminiyamu
