Kufotokozera:
Nano boron ufa ndi gawo loyaka kwambiri lamphamvu.Volumetric calorific value (140kg/cm3) ndi mass calorific value (59kg/g) ya elemental boron ndi yayikulu kwambiri kuposa yazinthu zina zamphamvu za molekyulu imodzi monga magnesiamu ndi aluminiyamu.
Ndipo ufa wa boron ndi mafuta abwino, makamaka ufa wa nano boron uli ndi mphamvu yoyaka kwambiri, kotero kuwonjezera ufa wa nano boron ku mabomba ophulika kapena ma propellants amatha kuonjezera mphamvu yamagetsi amphamvu.
Boron ufa ali ndi calorie yochuluka kwambiri komanso kuchuluka kwa calorific, ndipo ndi mafuta achitsulo okhala ndi chiyembekezo chogwiritsa ntchito bwino, makamaka pankhani ya zopangira zolimba zopanda mpweya.Pakali pano ndi ramjet yokhayo yolimba yomwe ingathe kukwaniritsa chikoka cha 10kN·s.Mphamvu ya propulsion pamwamba pa kg-1, kotero boron ndi imodzi mwamafuta oyenera kwambiri muzotulutsa mpweya wotsamira.
Kuti apititse patsogolo ntchito ya ufa wa boron, B / X (X = Mg, Al, Fe, Mo, Ni) tinthu tating'onoting'ono timakonzedwanso kuti tigwiritse ntchito popangira ma propellants.
Mkhalidwe Wosungira:
Boron Powder iyenera kusindikizidwa ndikusungidwa pamalo owuma, ozizira.Siziyenera kuwululidwa ndi mpweya kwa nthawi yayitali kuti mupewe kuphatikizika chifukwa cha chinyezi, zomwe zingakhudze magwiridwe antchito ndikugwiritsa ntchito.Kuphatikiza apo, pewani kuthamanga kwambiri ndikupewa kukhudzana ndi ma okosijeni.
