Chii chinoshandiswa neBoron Carbide (B4C)?
Nekuda kwekuoma kwayo:
Hunhu hukuru hweBoron Carbide, hunofadza mugadziri kana mainjiniya, kuomarara uye kusakara kwakabatana nako. Mienzaniso yekushandiswa kwakanaka kwehunhu uhwu inosanganisira: Makiyi; Mapuratifomu ezvombo zvemunhu nemotokari; Manotsi ekuputika kwegrit; Manotsi ekucheka jet emvura ane simba guru; Machira anodzivirira kukwenya nekukwenya; Zvishandiso zvekucheka nemadhayi; MaAbrasives; Macomposites esimbi; Mumabhureki emota.
Nekuda kwekusimba kwayo:
Boron carbide inoshandiswa kugadzira seZvidziviriro zvekudzivirira kurova kwezvinhu zvakapinza zvakaita semabara, zvidimbu, uye zvombo zvinokandwa. Inowanzo sanganiswa nezvimwe zvinhu panguva yekugadzirisa. Nekuda kwekusimba kwayo kwakanyanya, zvombo zveB4C zvinonetsa kuti bara ripinde. Zvinhu zveB4C zvinogona kupinza simba rebara zvobva zvabvisa simba rakadaro. Pamusoro pazvo paizopwanyika kuita zvidimbu zvidiki uye zvakaoma gare gare. Kushandisa zvinhu zveboron carbide, masoja, matangi, uye ndege kunogona kudzivirira kukuvara kwakakomba kubva kumabara.
Kune dzimwe nzvimbo:
Boron carbide chinhu chinoshandiswa zvakanyanya muzviteshi zvemagetsi enyukireya nekuda kwekugona kwayo kutora manyuturoni, mutengo wakaderera, uye manyuko akawanda. Ine chikamu chinopinza zvakanyanya. Kugona kweboron carbide kupinza manyuturoni pasina kugadzira maradionuclides anogara kwenguva refu kunoita kuti ive inokwezva semushonga unopinza manyuturoni anobva muzviteshi zvemagetsi enyukireya uye kubva kumabhomba e-neutron anorwisa vashandi. Boron Carbide inoshandiswa kudzivirira, semudonzvo wekudzora mureactor yenyukireya uye semapellets anodzima muzviteshi zvemagetsi enyukireya.
