Chii chinonzi Boron Carbide (B4C) inoshandiswa?
Nekuda kwekuoma kwayo:
Iwo akakosha zvimiro zveBoron Carbide, izvo zvinofadza kune mugadziri kana mainjiniya, kuomarara uye zvine chekuita neabrasive kupfeka kuramba. Mienzaniso yemhando yepamusoro yekushandiswa kwakanyanya kwezvivakwa izvi inosanganisira: Mapadlock; Personal uye motokari anti-ballistic armor plating; Grit blasting nozzles; High-pressure water jet cutter nozzles; Kukwenya uye pfeka machira anodzivirira; Kucheka midziyo uye kufa; Abrasives; Metal matrix composites; Mumabrake linings emotokari.
Nokuda kwekuoma kwayo:
Boron carbide inoshandiswa kugadzira seDziviriro Yezvombo kurwisa kukanganiswa kwezvinhu zvakapinza semabara, shrapnel, uye zvinokandwa. Inowanzo kusanganiswa nemamwe macomposites panguva yekugadzirisa. Nekuda kwekuoma kwayo, B4C nhumbi dzokurwa nadzo dzakanetsa kuti bara ripinde. B4C zvinhu zvinogona kutora simba rebara uye zvobva zvabvisa simba rakadaro. Nzvimbo yacho yaizopwanyika kuita tunhu tuduku uye twakaoma gare gare. Kushandisa boron carbide zvinhu, masoja, matangi, uye ndege zvinogona kudzivirira kukuvara kwakanyanya kubva kumabara.
Kune zvimwe zvivakwa:
Boron carbide chinhu chinoshandiswa zvakanyanya chekutonga mumagetsi emagetsi enyukireya nekuda kwekugona kwayo kutora neutron, mutengo wakaderera, uye yakawanda sosi. Iine high absorption cross-section. Kugona kweboron carbide kutora manyutroni pasina kugadzira maredhiyonuclides anogara kwenguva refu kunoita kuti itaridzike semushonga wemwaranzi yenyutroni inobuda muzvirimwa zvemagetsi enyukireya uye kubva kumabhomba anorwisa-vashandi neutron. Boron Carbide inoshandiswa kudzivirira, setsvimbo yekudzora mune yenyukireya reactor uye sekuvhara mapellets muchigadzirwa chemagetsi enyukireya.
