wehewehe:
ʻO ka pauka Nano boron he mea hoʻohūhū kiʻekiʻe.ʻOi aku ka nui o ka waiwai calorific volumetric (140kg/cm3) a me ka waiwai calorific mass (59kg/g) o ka boron elemental ma mua o nā mea ikaika ʻē aʻe e like me ka magnesium a me ka aluminika.
A he wahie maikaʻi ka pauka boron, ʻoi aku ka maikaʻi o ka hoʻopau ʻana o ka nano boron pauda, no laila e hoʻohui ʻia ka pauka nano boron i nā mea pahū a i ʻole nā mea hoʻolalelale hiki ke hoʻonui nui i ka ikehu o ka ʻōnaehana mea ikaika.
He kiʻekiʻe ka waiwai calorific nuipa Boron pauka a me ka nui calorific waiwai, a he metala wahie me ka maikaʻi noi prospects, oi loa aku ma ke kula o ka oxygen-ilihune paʻa propellants.ʻO ia wale nō ka ramjet paʻa i hiki ke hoʻokō i kahi manaʻo kikoʻī o 10kN·s.ʻO ka ikehu hoʻoulu ma luna o kg-1, no laila ʻo ka boron kekahi o nā wahie kūpono loa i nā mea hoʻolale lean oxygen.
No ka hoʻomaikaʻi ʻana i ka hana o ka pauka boron, ua hoʻomākaukau pū ʻia nā ʻāpana hui B/X (X=Mg, Al, Fe, Mo, Ni) no ka hoʻohana ʻana i nā propellants.
Kūlana mālama:
Pono e hoʻopaʻa ʻia ka Boron Powder a mālama ʻia i kahi maloʻo maloʻo.ʻAʻole pono e hōʻike ʻia i ka lewa no ka manawa lōʻihi e pale ai i ka agglomeration ma muli o ka wai, e hoʻopilikia i ka hana hoʻopuehu a me ka hopena hoʻohana.Eia kekahi, e pale i ke kaumaha kaumaha a pale i ka launa pū ʻana me nā oxidants.
