Boron Carbide ndi wozungulira wakuda wokhala ndi chimbudzi, omwe amadziwikanso kuti ndi diamondi wakuda, womwe ndi wa itorganic zinthu zopanda zitsulo. Pakadali pano, aliyense amadziwa zinthu za Boron Carbide, zomwe zitha kuchitika chifukwa cha zida zankhondo, chifukwa zili ndi kachulukidwe kakang'ono pakati pa zinthu zam'madzi, zimakhala ndi maluso apamwamba, ndipo amatha kugwiritsa ntchito bwino ma projekiti. Mphamvu ya mphamvu, ikamasungira katundu wotsika momwe mungathere. Koma kwenikweni, a Boron Carbide ali ndi malo ena abwino kwambiri, omwe angapangitse kuti azichita mbali yofunika kwambiri a alamu a Abrasion, zida zovomerezeka, mafakitale anyukiliya, Awessace ndi minda ina.
Katundu waBoron Carbide
Pankhani yazinthu zakuthupi, kuuma kwa Boron Carbide kokha pambuyo pa diamondi ndi cubic Boron Nichon Nitride, ndipo amatha kukhalabe olimba kwambiri kutentha kwambiri, omwe angagwiritsidwe ntchito ngati zinthu zosalimba kwambiri; Kuchulukitsa kwa boron carbide kwambiri (kachulukidwe kake kamene kamangokhala 2.52 g / cm3), opepuka kuposa zida wamba zadenga, ndipo zitha kugwiritsidwa ntchito m'munda wa Arospace; Boron Carbide ali ndi kuthekera kwabwino kwa neutron, kukhazikika kwamitundu yabwino, komanso malo osungunuka 2450 ° C, momwemonso amagwiritsidwa ntchito kwambiri m'makampani anyukiliya. Kutha kwa mtundu wa neutron kungakuthandizeni powonjezera ma b. Zida za Boron Carbide ndi morphology ndi mawonekedwe enanso zimakhalanso ndi zojambula zapadera; Kuphatikiza apo, a Boron Carbide ali ndi malo okwanira, modulu a solastic, pochulukitsa pang'ono ndi zabwino zabwino ndi zabwino zomwe zimapangitsa kuti zikhale zofunikira pa metaldurgy, mapanga, makina, ambostero. Mwachitsanzo, kuchuluka kwa chilengedwe komanso chosokoneza, kupanga zida zobisika, ndodo zowongolera zowongolera ndi ma armoelectric zinthu, etc.
Pankhani ya mankhwala, a Boron Carbide samakhudzana ndi acid, alkalis komanso mankhwala ambiri onunkhira kutentha, ndipo samachita ndi mpweya wa oxygen ndi mpweya wokhazikika. Kuphatikiza apo, a Boron Carbide ufa amayambitsidwa ndi halogen ngati othandizira achitsulo, ndipo a Boron amalowetsedwa pamtunda wa chitsulo, ndipo motero amalimbikitsa mphamvu ndi kuvala zinthu zake zabwino.
Tonse tikudziwa kuti chikhalidwe cha zinthuzo chimatsimikizira kugwiritsa ntchito, ndiye kuti a Boron Carbide ufa amakhala ndi ntchito yabwino kwambiri?Mainjiniya a R & D likulu laUraxmin.Co., Ltd. adapanga chidule chotsatira.
Kugwiritsa ntchitoBoron Carbide
1. Boron Carbide amagwiritsidwa ntchito ngati kupukuta
Kugwiritsa ntchito boron carbide ngati kugwiritsidwa ntchito makamaka kumagwiritsidwa ntchito pokupera ndi kupukutira kwa safiro. Mwa zina zapamwamba, kuuma kwa Boron Carbide kuli bwino kuposa kwa aluminiyamu osungira ndi silicon carbide, yachiwiri kwa daimon boron natride. Safiro ndi zinthu zabwino kwambiri zopindika kwambiri za semiconductor gan / Al 2 O3 yopepuka (ma LED), kuphatikiza masitepe akuluakulu a SOSS, ndi mafilimu apamwamba. Kusalala kwa pamwamba kuli pamwamba kwambiri ndipo kuyenera kukhala kwa ultra-yosalala kukhala yowonongeka. Chifukwa cha kulimba kwambiri komanso kulimba kwambiri kwa kapika kakang'ono kwa safiro (mohs Harness 9), yabweretsa zovuta kukonza mabizinesi.
Kuchokera pazomwe zidali ndi zokutira, zida zabwino kwambiri pokonza ndikupera makiyiki a safiro ndi diamondi yopanga, Boron Carbide, Silicon Carbide, ndi silicon Dioxide. Kuumitsa kwa diamondi yokwezeka kwambiri kumakhala kokwera kwambiri (mohs Harness 10) pokolola sapphire Mukadula silicon carbide, ranness nthawi zambiri imakhala yokwera ndipo kuthwa ndi osauka; Komabe, kuuma kwa silika sikokwanira (mohs Hardness 7), ndipo mphamvu yogaya imakhala yosauka, yomwe ndi yotakamwa komanso yogwira ntchito molimbika pogaya. Chifukwa chake, a Boron Carbide Abrasive (Mohs Hardness (Mohs Hardness 9.3) wakhala chinthu chabwino kwambiri pokonza ndi kupera ma khingstals apamwamba kwambiri, ndipo ali ndi luso labwino kwambiri pakukupera kwa saphror ndi kupsinjika kwa chowopsa cha epitaxial.
Ndikofunika kutchulapo kuti Boron Carbide pafupifupi 600 Celdic C, pamwamba ili mufilimu ya B2o3, yomwe ifewetsa mpaka kutentha kwambiri pakugwiritsa ntchito popukutira madzi opera. Komabe, malowa amalepheretsa B4C kuchokera pakukhala okonzeka kupitilira, kupangitsa kukhala ndi mapindu ake apadera pakugwiritsa ntchito zinthu zovomerezeka.
2. Kugwiritsa ntchito muzovomerezeka
Boron Carbide ali ndi mawonekedwe a anti-oxidation ndi kutentha kwambiri kukana. Amagwiritsidwa ntchito ngati zida zapamwamba komanso zosagwira ntchito zophatikizika ndipo zimagwiritsidwa ntchito kwambiri m'minda yosiyanasiyana ya metallingo, monga zitsulo zachitsulo ndi mipando ya miyala.
Ndi zosowa za kupulumutsa mphamvu ndi kugwiritsidwa ntchito kwa makampani achitsulo ndi chitsulo chamiyala yotsika komanso kafukufuku wa kaboni wa kaboni wa kaboni-asborm (nthawi zambiri a Carbor) Pakadali pano, magwiridwe antchito otsika-a carton magnesia-carbon majekelo amasintha ndikusintha kaboni wa kaboni wa magrix-carbon njerwa, ndikuwonjezera antioxidantsy. Pakati pawo, kaboni kaboni adapanga mafakitale a boron carbide ndi pang'ono kutengera kaboni wakuda amagwiritsidwa ntchito. Ufa wakuda wophatikizika, womwe umagwiritsidwa ntchito ngati kaboni napanga ndi antioxidant kwa otsika-carbon magnesia-carbor njerwa, zakwaniritsa zotsatira zabwino.
Popeza a Boron Carbide adzafewetsa pamlingo wapadera, umatha kuphatikizidwa ndi tinthu tating'onoting'ono. Ngakhale matendawa atayatsidwa, kanema wa B2o3 oxide pamwamba amatha kupanga chitetezo china ndikusewera gawo la anti-ocdid. Nthawi yomweyo, chifukwa makristar amapangidwa ndi zomwe anachita zimagawidwa mu matrix ndi mipata ya makhirter a zinthuzo, chifukwa mphamvu ya makwerero yopangidwa imafalikira, imachepetsa ming'alu.
3. Zida zolamba zogwiritsidwa ntchito pokonza chitetezo cha dziko
Chifukwa cha kuuma kwake, kulimba kwambiri, mphamvu yaying'ono, mphamvu yokoka, komanso kuchuluka kwa ziphuphu zapamwamba, Boron Carbide makamaka mogwirizana ndi zomwe zimapangitsa kuti zinthu zikhale zopepuka. Ndiye zinthu zabwino kwambiri zoteteza ndege, magalimoto, zida zankhondo, ndi matupi aumunthu; pakadali pano,Mayiko enaafunsira ndalama zotsika mtengo wa Boron Carbider Commentry, ndikulakalaka kulimbikitsa kugwiritsa ntchito zida zazikulu za Boron Carbidentist zotsutsana ndi zodzitchinjiriza.
4. Kugwiritsa ntchito mu malonda anyukiliya
Boron Carbide ali ndi gawo lalitali la neutron ndipo gawo lalikulu la enginen, ndipo limadziwika padziko lonse lapansi ngati njira yabwino kwambiri ya neutron yopenda nyukiliya. Pakati pawo, gawo lotentha la boron-10 Inootope ndi okwera kwambiri ngati 347 × 10 cm2, lachiwiri ndi zinthu zingapo monga gadolinium, Samarium, ndipo ndi ma ardium a neutron. Kuphatikiza apo, Boron Carbide ndi chuma, chiwonongeko chambiri, kukhazikika kwamitundu yabwino, sikukupanga ma radiobory ency mphamvu, ndipo amakhala ndi zida zowonongeka kwambiri monga zida zowongolera ndi zida zotetezera m'matumbo.
Mwachitsanzo, pamakampani anyukitala, kutentha kwambiri kwa mpweya-kutentha kumagwiritsa ntchito Boron Kudula kwa mpira ngati dongosolo lachiwiri lotseka. Pakachitika ngozi, pomwe dongosolo loyamba lotseka limalephera, makina achiwiri okhazikika amagwiritsa ntchito ma pellet ambiri a boron carbide free mu njira yowoneka bwino ya riacton ndikutseka mpira wa grophice wokhala ndi Boron Carbide. Ntchito yayikulu ya boron carbide pakati pa kutentha kwambiri kwa mpweya-kokhazikika ndikuwongolera mphamvu ndi chitetezo cha riyakitala. Njerwa njerwa zimaphatikizidwa ndi Boron carbide yolumikizira zinthu, zomwe zimatha kuchepetsa matenda a riutron a riyakitala.
Pakadali pano, zida zam'madzi za zida za nyukiliya zimaphatikizapo zinthu zotsatirazi: Boron Carbide (Roric Acids), Boron Steel (Ndondomeko ya Borotium), etc.
