He aha ka mea e hoʻohana ʻia ai ʻo Boron Carbide (B4C)?
No kona paʻakikī:
ʻO nā waiwai koʻikoʻi o Boron Carbide, he mea hoihoi i ka mea hoʻolālā a i ʻole ka ʻenekinia, ʻo ia ka paʻakikī a me ke kūpaʻa ʻana o ka ʻaʻahu abrasive. ʻO nā hiʻohiʻona maʻamau o ka hoʻohana pono ʻana o kēia mau waiwai: Padlocks; Pilikino a me ke kaʻa anti-ballistic armor plating; Grit blasting nozzles; Nā nozzles ʻokiʻoki wai kiʻekiʻe-kaomi; Nā uhi pale ʻōpala a me ke komo ʻana; Nā mea hana ʻoki a me nā make; Abrasives; Metal matrix composites; I loko o nā uhi paleki o nā kaʻa.
No kona paʻakikī:
Hoʻohana ʻia ka boron carbide e hana i nā pale kaua e pale aku ai i ka hopena o nā mea ʻoi e like me nā pōkā, nā ʻāpana ʻōpala, a me nā missiles. Hoʻohui pinepine ʻia me nā mea hui ʻē aʻe i ka wā e hana ʻia ai. Ma muli o kona paʻakikī kiʻekiʻe, paʻakikī ke komo ʻana o ka pale kaua B4C no ka pōkā. Hiki i ka mea B4C ke omo i ka ikaika o ka pōkā a laila hoʻopau i kēlā ikehu. E haki ka ʻili i nā ʻāpana liʻiliʻi a paʻakikī ma hope. Ma ka hoʻohana ʻana i nā mea boron carbide, hiki i nā koa, nā kaʻa kaua, a me nā mokulele ke pale aku i nā ʻeha koʻikoʻi mai nā pōkā.
No nā waiwai ʻē aʻe:
He mea hoʻomalu nui ʻia ka Boron carbide i nā hale hana mana nukelea no kona hiki ke omo neutron, ke kumu kūʻai haʻahaʻa, a me ke kumu waiwai nui. Loaʻa iā ia kahi ʻāpana keʻa omo kiʻekiʻe. ʻO ka hiki o ka boron carbide ke omo i nā neutron me ka ʻole o ka hana ʻana i nā radionuclides lōʻihi e hoʻolilo iā ia i mea hoihoi e like me ka mea omo no ka radiation neutron e kū mai ana i nā hale hana mana nukelea a mai nā pōkā neutron anti-personnel. Hoʻohana ʻia ʻo Boron Carbide e pale aku, ma ke ʻano he koʻokoʻo hoʻomalu i loko o ka reactor nukelea a ma ke ʻano he mau pellets pani i loko o kahi hale hana mana nukelea.
