Kushandiswa kweBoron Carbide Powder
Boron carbideikristaro nhema ine simbi inopenya, inozivikanwawo sedhaimani dema, inova inorganic isiri-metallic material.Kuomarara kweboron carbide kunongove mushure medhaimondi uye cubic boron nitride, uye inogona kuramba ichichengetedza simba repamusoro pakupisa kwepamusoro, iyo inogona kushandiswa seyakanaka-yepamusoro-yekushisa inodzivirira kupfeka zvinhu;iyo density yeboron carbide idiki kwazvo (theoretical density ingori 2.52 g/cm3), yakareruka kupfuura General ceramic zvinhu zvinogona kushandiswa mumunda weaerospace;boron carbide ine simba rekutora neutron, kugadzikana kwakanaka kwekupisa, uye nzvimbo yekunyungudika ye2450 ° C, saka inoshandiswa zvakanyanya muindasitiri yenyukireya.Panguva imwecheteyo, yayo neutron absorption kugona Inogona kuwedzeredzwa nekuwedzera B element;iyo boron carbide zvinhu zvine chaiyo morphology uye chimiro zvakare ine yakakosha photoelectric zvivakwa;uyezve, boron carbide ine yakakwira melting point, yakakwira elastic modulus, yakaderera yekuwedzera coefficient uye yakanaka oxygen absorption kugona, nezvimwe. indasitiri yemauto.Semuyenzaniso, simbi isingadziviriri uye isingapfeki, kugadzira nhumbi dzokurwa nadzo dzemabara, tsvimbo dzinodzora magetsi uye thermoelectric elements, nezvimwe.
Izvo zvakakosha zvekushandisa boron carbide ndezvizvi:
1.Kushandiswa kwe polishing abrasive
Kuiswa kweboron carbide seabrasive ndiko kunyanya kupenya kwesafire.Muzvinhu zvakaomesesa, kuomarara kwe boron carbide kwakakwirira kupfuura iyoaluminium oxideuye silicon carbide, chete yakaderera kune diamond uye cubic boron nitride.Boron carbide abrasive (Mohs kuomarara 9.3) ndiyo yakanyanya kunaka zvinhu kugadzira nekukuya makristasi esafire.Kana boron carbide iri pamusoro pe600 ℃, uso wayo unozoiswa oxidized muB2O3 firimu, inozonyorovesa kune imwe nhanho.Naizvozvo, haina kukodzera kuomeswa nekukuya nekupisa kwakanyanya mune abrasive application, asi chete yekupukuta mvura yekukuya.Nekudaro, ichi chivakwa chinogona kudzivirira imwe oxidation yeB4C, iyo inoita kuti ive neyakasiyana mabhenefiti mune refractory application.
2.Kushandisa refractory zvinhu
Boron carbide ine maitiro ekupikisa oxidation uye kupisa kwakanyanya.Inowanzo shandiswa seyepamusoro maumbirwo uye amorphous refractories muzvikamu zvakasiyana-siyana zvesimbi, sezvitofu zvesimbi, fenicha yemoto, etc. Boron carbide inopfava pakupisa kwepamusoro, saka inogona kunamatira kune imwe nzvimbo yezvimwe zvinhu.Kunyange kana chigadzirwa chacho chakanyanyisa, iyo B2O3 oxide firimu pamusoro payo inogona kuumba imwe dhigirii yekudzivirira uye kutamba basa rekudzivirira-oxidation.Panguva imwecheteyo, nekuti iyo columnar makristasi anogadzirwa nekuita anogovaniswa mumatrix uye gaka reiyo refractory, iyo porosity inoderedzwa, yepakati tembiricha simba inovandudzwa, uye kuwedzera kwevhoriyamu yemakristasi anogadzirwa anogona kuporesa vhoriyamu shrinkage uye. kuderedza mitswe.
3.Kushandiswa kwezvinhu zvisingapindi bara
Nekuda kwehukukutu hwayo hwepamusoro, kusimba kwepamusoro, kukwevera kudiki kwakananga uye kukwirira kwakasimba, boron carbide inonyanya kuenderana nemafambiro emidziyo isingaremekedze bulletproof, uye ndiyo yakanakisa bulletproof zvinhu zvendege, mota, zvombo, muviri wemunhu uye kumwe kudzivirira.
4.Applications muindasitiri yenyukireya
Boron carbide ine yakakwira neutron absorption cross section uye yakafara neutron absorption spectrum, iyo inozivikanwa pasi rese seyakanakisa neutron inonwisa muindasitiri yenyukireya.Boron carbide ine zviwanikwa zvakapfuma, corrosion resistance, good thermal stability, hapana radioactive isotopes, low second ray ray, etc., saka inoshandiswa zvakanyanya sechinhu chekudzora uye chinodzivirira zvinhu munyukireya reactor.Boron carbide ichagadzirwa kuita boron carbide rods mumunda wenyukireya reactor, uye ichaitwawo boron carbide poda nekuda kwekudiwa kwekuwedzera nzvimbo.
