Ukusetshenziswa kwe-Boron Carbide Powder
I-Boron carbideiyikristalu elimnyama eline-metallic luster, eyaziwa nangokuthi idayimane elimnyama, okuyingxenye ye-inorganic non-metallic.Ubulukhuni be-boron carbide kuphela ngemuva kwedayimane ne-cubic boron nitride, futhi isengakwazi ukugcina amandla aphezulu ekushiseni okuphezulu, okungasetshenziswa njengento efanelekile yokumelana nokushisa okuphezulu;ukuminyana kwe-boron carbide kuncane kakhulu (ukuminyana kwethiyori kungu-2.52 g/cm3 kuphela), ilula kunezinto ezijwayelekile zobumba ezingasetshenziswa emkhakheni we-aerospace;I-boron carbide inamandla okumunca i-neutron eqinile, ukuzinza okuhle kokushisa, nendawo yokuncibilika engu-2450 °C, ngakho isetshenziswa kabanzi embonini yenuzi.Ngesikhathi esifanayo, umthamo wayo wokumunca i-neutron Ingathuthukiswa ngokwengeziwe ngokungeza isici esingu-B;impahla ye-boron carbide ene-morphology ethile kanye nesakhiwo nayo inezakhiwo ezikhethekile ze-photoelectric;ngaphezu kwalokho, i-boron carbide inezinga eliphezulu lokuncibilika, i-modulus enwebekayo ephezulu, i-coefficient ephansi yokwandisa kanye nomthamo omuhle wokumuncwa komoya-mpilo, njll. imboni yezempi.Isibonelo, izingxenye ezimelana nokugqwala nezingagugi, ezenza izikhali ezingangenwa izinhlamvu, izinduku zokulawula i-reactor nezinto zikagesi we-thermoelectric, njll.


Izicelo eziyinhloko ze-boron carbide zimi kanje:
1.Ukusetshenziswa kwe-abrasive yokupholisha

Ukusetshenziswa kwe-boron carbide njenge-abrasive ikakhulukazi ukupholishwa kwesafire.Ezintweni eziqinile kakhulu, ubulukhuni be-boron carbide buphakeme kunaboi-aluminium oxidekanye ne-silicon carbide, engaphansi kuphela kwedayimane ne-cubic boron nitride.I-Boron carbide abrasive (Mohs hardness 9.3) iyinto ekahle kakhulu yokucubungula nokugaya amakristalu esafire.Uma i-boron carbide ingaphezu kuka-600 ℃, ubuso bayo buzokwenziwa i-oxidized ibe yifilimu ye-B2O3, ezoyithambisa ngokwezinga elithile.Ngakho-ke, akufanelekile ukugaya okomile ngokushisa okwedlulele ekusetshenzisweni kwe-abrasive, kodwa kuphela ukupholisha ukugaya uketshezi.Kodwa-ke, lesi sakhiwo singavimbela i-oxidation eyengeziwe ye-B4C, okwenza ibe nezinzuzo ezihlukile ekusetshenzisweni kwe-refractory.
2.Ukusetshenziswa kwezinto eziphikisayo

I-Boron carbide inezici zokumelana ne-oxidation kanye nokumelana nokushisa okuphezulu.Ngokuvamile isetshenziswa njengezici ezithuthukisiwe ezinokwakheka okuthuthukile kanye ne-amorphous emikhakheni ehlukahlukene ye-metallurgy, njengezitofu zensimbi, ifenisha yomlilo, njll. I-Boron carbide izothamba ekushiseni okuphezulu, ngakho ingakwazi ukunamathela ebusweni bezinye izinhlayiya zezinto ezibonakalayo.Ngisho noma umkhiqizo uminyene, ifilimu ye-B2O3 oxide ebusweni bayo ingakha izinga elithile lokuvikela futhi idlale indima ephikisana ne-oxidation.Ngesikhathi esifanayo, ngenxa yokuthi amakristalu ekholomu akhiqizwa ukusabela asatshalaliswa ku-matrix kanye negebe le-refractory, i-porosity iyancishiswa, amandla okushisa aphakathi ayathuthukiswa, futhi ukunwetshwa kwevolumu yamakristalu akhiqiziwe kungaphulukisa ukuncipha kwevolumu futhi. nciphisa imifantu.
3.Ukusetshenziswa kwezinto ezingangenwa izinhlamvu

Ngenxa yokuqina kwayo okuphezulu, amandla aphezulu, amandla adonsela phansi amancane athile kanye nokumelana nokunwebeka okukhulu, i-boron carbide ihambisana ikakhulukazi nokuthambekela kwezinto ezivikela izinhlamvu ezingasindi, futhi iyimpahla evikela inhlamvu engcono kakhulu yezindiza, izimoto, izikhali, umzimba womuntu nokunye ukuvikela.
4.Izicelo embonini yenuzi

I-Boron carbide inesigaba esiphambanayo sokumuncwa kwe-neutron ephezulu kanye ne-spectrum yokumunca i-neutron ebanzi, eyaziwa emhlabeni wonke njengesimunyisi esingcono kakhulu se-neutron embonini yenuzi.I-Boron carbide inezinsiza ezicebile, ukumelana nokugqwala, ukuzinza okuhle kokushisa, awekho ama-isotopes anemisebe, amandla emisebe ephansi ephansi, njll., ngakho-ke isetshenziswa kabanzi njengento yokulawula kanye nezinto ezivikelayo kuma-reactors enuzi.I-Boron carbide izokwenziwa ibe yizinduku ze-boron carbide emkhakheni we-nuclear reactor, futhi izophinde yenziwe ibe yi-boron carbide powder ngenxa yesidingo sokwandisa indawo engaphezulu.
