Daim ntawv thov ntawm Boron Carbide

Tswj kev sib tsoo nuclear
Boron carbide tuaj yeem nqus tau ntau cov neutrons yam tsis tsim cov isotopes radioactive, yog li nws yog ib qho zoo tagnrho neutron absorber hauv nuclear fais fab nroj tsuag, thiab neutron absorbers mas tswj tus nqi ntawm nuclear fission. Boron carbide feem ntau yog tsim los rau hauv cov pas nrig tswj tau hauv cov tshuab hluav taws xob nuclear, tab sis qee zaum nws tau ua cov hmoov txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam, nws yuav tsum tau ua cov hmoov nplej.
Thaum lub sij hawm Chernobyl nuclear kev huam yuaj nyob rau hauv 1986, Russia poob ze li ntawm 2, 000 tons ntawm boron carbide thiab xuab zeb, uas nws thiaj li tso tseg cov saw cov tshuaj tiv thaiv nyob rau hauv lub reactor.
Abrasive cov ntaub ntawv
Vim tias boron carbide tau siv los ua cov xuab zeb coarse abrasive rau lub sijhawm ntev. Vim nws qhov siab melting point, nws tsis yooj yim rau cam khwb cia rau hauv cov khoom siv dag zog, tab sis los ntawm melting hmoov ntawm qhov kub thiab txias, nws tuaj yeem ua tiav rau hauv cov duab yooj yim. Nws yog siv rau kev sib tsoo, sib tsoo, drilling thiab polishing ntawm cov ntaub ntawv nyuaj xws li cemented carbide thiab gemstones.
Txheej
Boron carbide kuj tseem siv tau los ua cov txheej txheem ceramic rau cov nkoj thiab cov nyoob hoom qav taub. Nws yog lub teeb nyob rau hauv qhov hnyav thiab muaj peev xwm tiv thaiv armor-piercing projectiles los ntawm kev nkag mus rau hauv cov txheej txheem kub nias rau hauv ib qho kev tiv thaiv txheej.
Nozzles
Hauv kev lag luam riam phom, nws tuaj yeem siv los ua phom nozzles. Boron carbide yog ib qho nyuaj heev thiab hnav-tiv taus, tsis hnov ​​​​mob nrog cov kua qaub thiab alkalis, tiv taus qhov kub / qis thiab kub siab, muaj qhov ntom ntom ntawm Ntau dua lossis sib npaug ntawm 2.46g / cm3; microhardness Ntau dua los yog sib npaug rau 3500kgf / mm2, khoov lub zog Ntau dua los yog sib npaug rau 400MPa, thiab melting point ntawm 2450 degree.
Vim hais tias ntawm cov yam ntxwv saum toj no hnav-resistant thiab siab-hardness ntawm boron carbide nozzles, boron carbide sandblasting nozzles yuav maj mam hloov cov paub sandblasting nozzles ua los ntawm cemented carbide / tungsten steel thiab silicon carbide, silicon nitride, aluminium oxide, zirconium oxide, thiab lwm yam.
Lwm tus
Boron carbide kuj tseem siv rau hauv kev tsim cov hlau borides, smelting ntawm boron sodium, boron alloys, thiab tshwj xeeb vuam.
