He aha te whakamahinga o te Boron Carbide (B4C)?
Mō tōna pakeketanga:
Ko ngā āhuatanga matua o te Boron Carbide, e pārekareka ana ki te kaihoahoa, ki te miihini rānei, ko te pakeke me te ātete ki te kakahu pakaru. Ko ngā tauira noa o te whakamahinga pai o ēnei āhuatanga ko: Ngā raka; Te whakakikorua i ngā pukupuku ārai-porowhita whaiaro me ngā waka; Ngā pūwero pupuhi kirikiri; Ngā pūwero tapahi wai pēhanga teitei; Ngā paninga ātete ki te rakuraku me te kakahu; Ngā taputapu tapahi me ngā mate; Ngā mea pakaru; Ngā mea hiato whakarewa; I roto i ngā arai parai o ngā waka.
Mō tōna pakari:
Ka whakamahia te boron carbide hei hanga i ngā pukupuku tiaki hei ārai i te pānga o ngā mea koi pērā i ngā matā, ngā konganuku me ngā pere. I te nuinga o te wā ka honoa ki ētahi atu mea hanga i te wā e tukatukahia ana. Nā tōna pakari, he uaua ki te matā te uru ki te pukupuku B4C. Ka taea e te rauemi B4C te mimiti i te kaha o te matā, kātahi ka tohatoha i taua kaha. Ka pakaru te mata ki ngā matūriki iti, mārō hoki i muri mai. Mā te whakamahi i ngā rauemi boron carbide, ka taea e ngā hōia, ngā tāke, me ngā waka rererangi te karo i ngā whara kino mai i ngā matā.
Mō ētahi atu āhuatanga:
He rauemi whakahaere whānuitia te boron carbide i roto i ngā tipu hiko karihi nā tōna kaha ki te mimiti i ngā neutron, te utu iti, me te nui o te pūtake. He nui te wāhanga whakawhiti mimiti. Nā te kaha o te boron carbide ki te mimiti i ngā neutron me te kore e hanga i ngā radionuclides roa te ora, he mea ātaahua hei mimiti i te irahiko neutron e puta mai ana i roto i ngā tipu hiko karihi me ngā poma neutron anti-kaimahi. Ka whakamahia te boron carbide hei parepare, hei tokotoko whakahaere i roto i te tauhohenga karihi, hei pire kati hoki i roto i te tipu hiko karihi.
