I-boron ye-boron yi-crystal emnyama ene-metallic luster, ekwabizwa ngokuba yidayimane emnyama, eye yeyoorganic engeyiyo i-inorganic. Okwangoku, wonke umntu uqhelene nento ebonakalayo ye-boron ye-boron ye-boron, enokubangelwa kukusetyenziswa kwe-bulletroofproof, kuba kunezinto eziphantsi ze-celetroof, kuba kunezibonelelo eziphakamileyo ze-celectus, kwaye zinokufezekisa ukusetyenziswa kakuhle kwe-microral. Iziphumo zamandla, ngelixa ugcina umthwalo usezantsi kangangoko kunokwenzeka. Kodwa enyanisweni, i-boron ye-boron ineepropathi ezininzi, ezinokwenza ukuba idlale indima ebalulekileyo kwi-aravins, izixhobo zokutshaja, ishishini lenyukliya, i-aerospace kunye namanye amasimi.
Iipropathi zeI-boron carbide
Ngokwemigaqo yepropathi yomzimba, ubunzima be-boron carbide kuphela emva kwedayimani kunye ne-Boron Bornide, kwaye isenokugcina amandla aphezulu kubushushu obuphezulu, onokusetyenziswa njengempahla efanelekileyo yokunganyangeki; Ukuxinana kwe-boron ye-boron incinci kakhulu (i-theoretical dexity kuphela i-2.52 g / cm3), ilula kunezixhobo ze-ceramace eqhelekileyo, kwaye zinokusetyenziswa kwintsimi ye-aerospace; I-Boron ye-boron inesakhono esomeleleyo se-neutron se-neutron se-neutron sen, uzinzo oluhle, kunye nendawo yokunyibilika engama-2400 ° C, ngoko ke isetyenziswa ngokubanzi kwishishini lenyukliya. Isakhono sokufumana i-Neutron se-Neutron sinokuphuculwa ngakumbi ngokongeza ukongeza izinto ze-B; Izixhobo ze-boron ye-borbide ne-morphology ye-morphology kunye nesakhiwo nazo zineefoto ezikhethekileyo zefoto; Ukongeza, i-boron ye-boron inendawo ephezulu yokunyibilika, i-Elastic ePhezulu, ukwandiswa okuphakathi kwe-Elastic, ezi zibonelelo zenza ukuba ibe sisixhobo esinokubakho kwimimandla emininzi efana ne-mechicmargy, oomatshini, i-aerospace kunye neshishini le-aerospace kunye neshishini lomkhosi. Umzekelo, iindawo ezinganyangekiyo ezixhaphaza kwaye zidinisa, zenza izixhobo ze-buletroof, zenza i-bulletroof Armoof, i-Recletroofroof Armor, ukulawula iiRods kunye neZilwanyana, njl.
Ngokweempawu zekhemikhali, i-boron ye-boron ayiphendulanga nge-acid, ialkalis kunye neyona ndawo inqabileyo yegumbi, kwaye i-halogn yegesi kubushushu begumbi, kwaye iipropathi zekhemikhali ziyazinza. Ukongeza, i-boron ye-boron carbide isebenze yi-halogn njengearhente yokuhamba ngentsimbi, kwaye i-boron ingene kumphezulu wefilimu ukwenza ifilimu yentsimbi, ngokuphucula amandla, kunye neepropathi zekhemikhali zibhetele.
Sonke siyayazi ukuba uhlobo lwezinto ezibonakalayo zimisela ukusetyenziswa, ke zona izicelo ezisebenzisa i-boron carbide powder isebenze?Iinjineli ze-R & D iziko leI-UrbandMine Tech.Co., ltd. yenze esi sishwankathelo silandelayo.
Ukusetyenziswa kweI-boron carbide
I-1. I-Boron ye-boron isetyenziswa njengokuphumeza
Ukusetyenziswa kwe-boron carbide njengoko i-abrasive isetyenziselwa ikakhulu ukugaya kunye nokuguqulwa kwesafire. Phakathi kwezinto ezingaphezulu, ubushushu be-boron ye-boron bhetele kuneYaluminum oxide kunye ne-silicon carbide, yesibini kuphela kwidayimani kunye ne-boron ye-cuic witride. Sapphire is the most ideal substrate material for semiconductor GaN/Al 2 O3 light-emitting diodes (LEDs), large-scale integrated circuits SOI and SOS, and superconducting nanostructure films. Ukugudisa komphezulu kuphakame kakhulu kwaye kuya kuba yinto egudileyo ye-Ultra Ngenxa yamandla aphezulu kunye nobunzima obuphakamileyo besafire (mohs ubunzima 9), buzise ubunzima obukhulu ukulungisa amashishini.
Ukusuka kwimbono yezixhobo kunye nokugaya, ezona zixhobo zibalaseleyo ze-sapshire yidayimane yedayimani, i-boron carbide, i-silicon carbide, nasesikin dioksi. Ubulukhuni bedayimani yokufakelwa bungaphezulu kakhulu (I-MOHS HARD 10) Xa ugaya i-saphire wafer, iyakukhulisa umphezulu, ichaphazele ukuguqula ukukhanya kwesafi, kwaye ixabiso liyabiza; Emva kokusika i-carbide ye-silicon ye-silicon, ratey Rid ihlala iphezulu kwaye ukungcola kuhlwempuzekile; Nangona kunjalo, ubunzima be-silica akwanele (i-MOHS Hardy 7), kwaye amandla agadileyo ahluphekile, ochitha ixesha kunye nokusebenza nzima kwinkqubo yokugaya. Ke ngoko, i-boron carbide (mohs ubunzima 9.3) iyeyona nto ifanelekileyo ye-safshire ye-safire ye-safehire ye-safhire ye-safehire ye-safehire ye-safehire ye-safires ye-saffises.
Kufanelekile ukukhankanya ukuba xa i-borbide ye-boron ingaphezulu kwama-600 ° C, umphezulu uya kuba yifilimu ye-B2O3, eya kuthi ilungele ukugaya okuthile kwizicelo eziphezulu kwizicelo ezenziweyo, kuphela ezilungele ukugaya i-ralingles. Nangona kunjalo, le ndlu ithintela i-B4C ekubeni ichukumiseke ngakumbi, iyenza ineengenelo ezizodwa ekusebenziseni izixhobo zokutsha.
2. Isicelo kwizinto ezihlaziyiweyo
I-boron ye-boron ineempawu zokulwa i-anti-oxidation kunye nokuchasana nobushushu obuphezulu. Isetyenziswa ngokubanzi njengezinto eziphambili ze-Advances kwaye zisetyenziswa kakhulu kwiinkalo ezahlukeneyo ze-metallgergy, ezinjengesitopu sentsimbi kunye nefenitshala yeKitn.
Ngeemfuno zolondolozo lwamandla kunye nokusetyenziswa kwe-Iron kunye neSpeel Sybhoni yentsimbi kunye ne-Carbon Stee-Stebon Stee-Steeds, i-8% yomxholo we-carbon magnen, i-8% itsaleleka ngakumbi kumashishini asekhaya nawangaphandle. Okwangoku, ukwenziwa kwentsebenzo ye-carbon magnesia-carbon kuphuculwa ngokubanzi ngokuphucula ubume bekhabhoni, ukuqhuba isakhiwo se-matrix yezitena ze-magnesia, kunye nokongeza i-Antisobyents ePhezulu. Phakathi kwawo, i-carbon enegrafu equlunqwe ye-Boron ye-boron ye-boron kunye ne-carbon eguquliweyo isetyenziswa. I-powder emnyama emnyama, esetyenziswe njengomthombo wekhabhoni kunye ne-antioxidant ye-carbon ye-carbon magnon magnen, iphumelele iziphumo ezilungileyo.
Kuba i-borbide iya kuthambekela kwinqanaba elithile kubushushu obuphezulu, inokudityaniswa kumphezulu wezinye amasuntswana ezinto. Nokuba imveliso ihlaziyekile, ifilimu ye-B2O3 ye-oxide kumphezulu inokwenza ukhuseleko oluthile kwaye idlale indima echasene ne-oxidation. Kwangelo xesha, kuba iikristali ze-colminari eziveliswa yindlela yokusabela zisasazwa kwi-matrix kunye nezithuba zezinto ezihlaziyiweyo, amandla amaqondo obushushu aphuculweyo, anokuphilisa ukuntywila.
I-3. Izixhobo zeBulletroof ezisetyenziselwa ukomeleza isizwe
Ngenxa yobunzima bayo obuphakamileyo, amandla aphezulu, ubuninzi obuthile, kunye namanqanaba aphezulu okuxhathisa ibala, i-boron carbide ikakhulu ihambelana nemeko ye-bullet fitroof. Yeyona mpahla intle yebhulethi yokukhuselwa kwenqwelomoya, izithuthi, izixhobo, kunye nemizimba yabantu; okwangoku,Amanye amazweUcebe uphantsi kwe-boron ye-boron ye-boron echasene ne-Anti-Forting, ejolise ekukhuthazeni ukusetyenziswa kwe-boron carbide enkulu ye-boron intsholongwane kwishishini lezokhuseleko.
I-4. Ukusetyenziswa kwishishini lenyukliya
I-boron ye-boron inecandelo le-neutron enqamlezayo kunye ne-neuttroni enkulu ye-neutron, kwaye yamkelwe kwilizwe liphela njengeyona ndawo ibalaseleyo ye-neutron ishishini. Among them, the thermal section of boron-10 isotope is as high as 347×10-24 cm2, second only to a few elements such as gadolinium, samarium, and cadmium, and is an efficient thermal neutron absorber. Ukongeza, i-boron ye-boron ityebile kwizibonelelo, ukunganyangeki okunganyangekiyo, uzinzo oluhle, kwaye lingavelisi i-radiapes, kwaye isebenza ngamandla e-ray, i-boron ye-carbide isetyenziswa ngokubanzi njengezixhobo zokulawula kunye nezinto ezikhuselayo kwi-nuclear reactors.
Umzekelo, kumzi-mveliso wenyukliya, umqondo opholileyo weqondo-gesi opholileyo usebenzisa i-boron evala inkqubo yebhola yebhola njengenkqubo yesibini yokuvalwa. Kwimeko yengozi, xa inkqubo yokuqalisa i-Shutdown iyasilela, inkqubo yesibini isebenzisa inani elikhulu le-biel ye-boron ye-boron ye-boron ye-boron carbide iwele kwi-teedown yebhola yomdiliya, apho ibhola yegram equka ibhola ye-boron ene-boron ye-boron ye-boron ye-boron ye-boron ye-boron ye-boron ye-boron ye-boron ye-boron ye-boron ye-boron ye-boron carbide. Owona msebenzi ophambili we-boron ye-boron carbide kwiqondo eliphezulu lobushushu igesi kukulawula amandla kunye nokhuseleko lwesakhiwo. Isitena sekharbon sifakwe kwi-boron ye-boron ye-boron ye-boron ye-neutron neutron ye-neutron ye-neutron ye-neutron isuswe inqanawa yoxinzelelo lwe-reactor.
Okwangoku, imilinganiselo yokwahlulahlula iincwadi zenyukliya ibandakanya ezi zinto zilandelayo: i-boron ye-boron ye-boron (i-rods, i-boron yenkunkuma), i-Boron Acid (i-Boron Apper), i-boron yenkunkuma), njl.
