Nqe lus piav qhia:
Nano boron hmoov yog cov khoom siv hluav taws xob siab.Lub volumetric calorific tus nqi (140kg / cm3) thiab huab hwm coj calorific nqi (59kg / g) ntawm elemental boron nyob deb ntau dua li cov ntawm lwm yam ib leeg-molecule energetic ntaub ntawv xws li magnesium thiab txhuas.
Thiab boron hmoov yog cov roj zoo, tshwj xeeb tshaj yog nano boron hmoov muaj kev sib xyaw ua ke ntau dua, yog li ntxiv nano boron hmoov rau cov khoom tawg lossis cov khoom siv hluav taws xob tuaj yeem ua kom lub zog ntawm cov khoom siv zog.
Boron hmoov muaj ib tug loj loj calorific nqi thiab ntim calorific nqi, thiab nws yog ib tug hlau roj nrog zoo daim ntawv thov kev cia siab, tshwj xeeb tshaj yog nyob rau hauv lub tshav pob ntawm cov khoom uas tsis muaj oxygen.Tam sim no nws yog tib qho khoom ramjet uas tuaj yeem ua tiav qhov kev xav tau tshwj xeeb ntawm 10kN·s.Lub zog txhawb zog siab tshaj kg-1, yog li boron yog ib qho ntawm cov khoom siv zoo tshaj plaws hauv cov pa oxygen-lean propellants.
Txhawm rau txhim kho kev ua haujlwm ntawm boron hmoov, B / X (X = Mg, Al, Fe, Mo, Ni) cov khoom sib xyaw kuj tau npaj siv rau hauv cov khoom siv.
Cia txias:
Boron hmoov yuav tsum tau muab kaw thiab khaws cia rau hauv qhov chaw qhuav thiab txias.Nws yuav tsum tsis txhob raug huab cua ntev ntev los tiv thaiv agglomeration vim noo noo, uas yuav cuam tshuam rau kev ua haujlwm dispersion thiab siv cov nyhuv.Tsis tas li ntawd, tsis txhob hnyav hnyav thiab tsis txhob sib cuag nrog oxidants.
