2.Litšobotsi tsa motlakase tsa thepa.
The conductivity ea thepa ea aluminium foam e nyane haholo ho feta ea thepa e tiileng ea aluminium.
Thermal conductivity ea aluminium foam e nyane haholo ho feta ea aluminium e tiileng, e ka bang 0.1 - 0.2 linako tsa aluminium e tiileng.
Ntle le moo, aluminium ea foam e boetse e na le e thata, e sa cheng, ha e bonolo ho oxidation, ha ho bonolo ho hlahisa botsofali, ho hanyetsa boemo ba leholimo bo botle,litšobotsi tse ntle tsa ho hlaphoheloa le ho tsosolosoa.
Ts'ebetso e ntle ea ts'ireletso ea motlakase: ha maqhubu a maqhubu a motlakase a le 2.6-18GHZ,
matla a ho sireletsa motlakase oa foam ea aluminium e ka fihla ho 60-90dB.
