O le a le mea e fa'aoga ai le Boron Carbide(B4C)?
Mo lona maaa:
O mea taua o le Boron Carbide, e fiafia i ai le tagata mamanu poʻo le inisinia, o le maaa ma le faʻaogaina o le faʻaogaina o le ofuina. O fa'ata'ita'iga masani o le fa'aogaina lelei o nei meatotino e aofia ai: Loka; Fa'aofuofu tau le tagata lava ia ma ta'avale; Fa'asu'u fa'ato'a fa'afefe; Fa'asuavai fa'amama fa'amama maualuga; O pa'u fa'asa'o ma ofuina; Mea faigaluega tipi ma oti; Abrasive; u'amea matrix composites; I totonu o laina taofi o taavale.
Mo lona malosi:
O le Boron carbide e fa'aaogaina e fai ma 'Autau Puipui e tetee atu ai i a'afiaga o mea ma'ai e pei o pulufana, ma'i ma'i fana. E masani ona tuʻufaʻatasia ma isi mea faʻapipiʻi i le taimi o gaioiga. Ona o lona malosi maualuga, o le ofutau B4C e faigata mo le pulufana ona ulu. B4C mea e mafai ona mitiia le malosi o le pulufana ona faʻaumatia ai lea o le malosi. O le a malepelepe le pito i ni vaega laiti ma malo mulimuli ane. O le faʻaaogaina o mea faʻapipiʻi boron, o fitafita, tane, ma vaalele e mafai ona aloese mai manuʻa tuga mai pulu.
Mo isi meatotino:
O le Boron carbide o se mea fa'aoga tele e fa'aogaina i fale eletise faaniukilia mo lona malosi e fa'afefete ai neutron, tau maualalo, ma le tele o punaoa. O lo'o i ai se fa'a'ese'esega fa'aoso maualuga. O le malosi o le boron carbide e mitiia ai neutrons e aunoa ma le fausiaina o radionuclides umi-ola e avea ai ma se miti mo le neutron radiation e tulai mai i fale eletise faaniukilia ma mai pomu neutron anti-personnel. O le Boron Carbide e faʻaaogaina e talipupuni ai, e fai ma tootoo faʻatonutonu i totonu o le masini faaniukilia ma faʻapipiʻi pellets i totonu o se fale eletise faaniukilia.
