Kugwiritsa ntchito Boron Carbide Powder
Boron carbidendi kristalo wakuda wokhala ndi zitsulo zonyezimira, wotchedwanso diamondi yakuda, yomwe ndi zinthu zopanda chitsulo.Kuuma kwa boron carbide kumangochitika pambuyo pa diamondi ndi kiyubiki boron nitride, ndipo imatha kukhalabe ndi mphamvu yayikulu pakutentha kwambiri, yomwe ingagwiritsidwe ntchito ngati chinthu choyenera cha kutentha kosamva kutentha;kachulukidwe ka boron carbide ndi kakang'ono kwambiri (kachulukidwe kakachulukidwe ndi 2.52 g/cm3), chopepuka kuposa zida zonse za ceramic zitha kugwiritsidwa ntchito m'munda wamlengalenga;boron carbide ili ndi mphamvu yamphamvu yamayamwidwe a nyutroni, kukhazikika kwamafuta abwino, komanso malo osungunuka a 2450 ° C, motero imagwiritsidwanso ntchito kwambiri pamakampani anyukiliya.Nthawi yomweyo, mphamvu yake yamayamwidwe ya neutroni Itha kupitilizidwanso powonjezera gawo la B;zinthu za boron carbide zomwe zili ndi morphology ndi kapangidwe kake zimakhalanso ndi mawonekedwe apadera azithunzi;kuwonjezera apo, boron carbide ili ndi malo osungunuka kwambiri, modulus yotanuka kwambiri, kukulitsa kocheperako komanso mphamvu yabwino yoyamwitsa okosijeni, ndi zina zambiri. makampani ankhondo.Mwachitsanzo, zida zolimbana ndi dzimbiri komanso zosamva kuvala, kupanga zida zankhondo zoteteza zipolopolo, ndodo zowongolera riyakitala ndi zinthu zamagetsi zamagetsi, ndi zina zambiri.
Ntchito zazikulu za boron carbide ndi izi:
1.Kugwiritsa ntchito kupukuta abrasive
Kugwiritsa ntchito boron carbide ngati abrasive makamaka kupukuta kwa safiro.Muzinthu zolimba kwambiri, kuuma kwa boron carbide ndikoposa kwaaluminium oxidendi silicon carbide, yokhayo yotsika kuposa diamondi ndi kiyubiki boron nitride.Boron carbide abrasive (Mohs hardness 9.3) ndiye chinthu choyenera kwambiri pokonza ndikupera makhiristo a safiro.Boron carbide ikakhala pamwamba pa 600 ℃, pamwamba pake imapangidwa ndi oxidized kukhala filimu ya B2O3, yomwe ingafewetse pang'ono.Chifukwa chake, sikoyenera kupukuta kowuma ndi kutentha kwakukulu muzogwiritsira ntchito abrasive, koma kupukuta madzi akupera.Komabe, katunduyu amatha kuletsa makutidwe ndi okosijeni ena a B4C, omwe amapangitsa kuti akhale ndi mwayi wapadera wogwiritsa ntchito refractory.
2.Kugwiritsa ntchito zipangizo zotsutsa
Boron carbide ili ndi mawonekedwe a kukana kwa okosijeni komanso kukana kutentha kwambiri.Nthawi zambiri amagwiritsidwa ntchito ngati zapamwamba zowoneka bwino ndi amorphous refractories m'madera osiyanasiyana azitsulo, monga masitovu achitsulo, mipando yamoto, etc. Boron carbide idzafewetsa kutentha kwakukulu, kotero ikhoza kumamatira pamwamba pa particles zina zakuthupi.Ngakhale mankhwalawa atakhala olimba, filimu ya B2O3 oxide pamwamba pake imatha kupanga chitetezo chambiri ndikuchita gawo lodana ndi okosijeni.Panthawi imodzimodziyo, chifukwa makhiristo opangidwa ndi zomwe amachitira amagawidwa mu matrix ndi kusiyana kwa refractory, porosity imachepetsedwa, mphamvu ya kutentha kwapakati imakhala bwino, ndipo kuwonjezeka kwa voliyumu kwa makhiristo opangidwa kumatha kuchiritsa kuchepa kwa voliyumu ndi kuchepetsa ming'alu.
3.Kugwiritsa ntchito zinthu zoteteza zipolopolo
Chifukwa cha kuuma kwake kwakukulu, mphamvu zake zazikulu, mphamvu yokoka yaing'ono komanso kukana zotanuka kwambiri, boron carbide imagwirizana kwambiri ndi zinthu zopepuka za bulletproof, ndipo ndizinthu zabwino kwambiri zoteteza zipolopolo za ndege, magalimoto, zida, thupi la munthu ndi chitetezo china.
4.Mapulogalamu mumakampani a nyukiliya
Boron carbide ili ndi gawo lalikulu la mayamwidwe a nyutroni komanso sipekitiramu yoyamwa ya neutroni, yomwe imadziwika padziko lonse lapansi kuti ndiyomwe imayamwa bwino kwambiri munyuturoni pamakampani anyukiliya.Boron carbide ili ndi chuma cholemera, kukana kwa dzimbiri, kukhazikika kwamafuta, palibe isotopu ya radioactive, mphamvu yochepera yachiwiri ya ray, ndi zina zotere, chifukwa chake imagwiritsidwa ntchito kwambiri ngati zinthu zowongolera komanso zotchingira mu zida zanyukiliya.Boron carbide idzapangidwa kukhala ndodo za boron carbide m'munda wa nyukiliya wa nyukiliya, ndipo idzapangidwanso kukhala ufa wa boron carbide chifukwa chofuna kuwonjezera malo.
