Boron Nitride: Cov Khoom Siv Miracle rau Rocket Nozzles thiab Casings
Thaum nws los txog rau kev tsim thiab tsim lub foob pob hluav taws cav, txhua qhov nthuav dav suav. Txawm tias kev txhim kho me me tuaj yeem ua rau muaj txiaj ntsig zoo hauv kev ua haujlwm, kev ua tau zoo, thiab kev nyab xeeb. Tias yog vim li cas engineers thiab cov kws tshawb fawb tau nqis peev ntau rau hauv kev tshawb nrhiav cov ntaub ntawv tshiab uas tuaj yeem tiv taus qhov huab cua ntawm qhov chaw mus ncig. Thiab ib yam khoom uas tau sawv tawm hauv xyoo tas los no yog boron nitride.
Boron nitride, los yog BN, yog ib tug compound ua los ntawm boron thiab nitrogen atoms. Nws muaj qee qhov zoo tshaj plaws uas ua rau nws txaus nyiam heev rau kev siv aerospace. Rau ib yam, nws yog incredibly muaj zog thiab ruaj, nrog ib tug hardness piv rau pob zeb diamond. Nws tseem tuaj yeem tiv taus qhov kub thiab txias, txog li 3000 degrees Celsius. Thiab tsis zoo li ntau lwm yam ntaub ntawv, nws yog ruaj khov nyob rau hauv lub xub ntiag ntawm oxygen thiab lwm yam corrosive agents.
Cov khoom no ua rau boron nitride zoo tagnrho rau siv nyob rau hauv foob pob ua ntxaij nozzles thiab casings. Nyob rau hauv lub foob pob hluav taws cav, lub nozzle yog cov khoom uas hloov cov high-pressure, high-temperature gas generated los ntawm cov txheej txheem combustion rau hauv thrust, propelling lub foob pob ua ntxaij rau pem hauv ntej. Nozzles raug rau cov cua kub loj thiab siab, thiab yuav tsum muaj peev xwm tiv taus cov erosive los ntawm cov pa pa. Boron nitride yog ib qho zoo meej haum rau daim ntawv thov no, vim nws tuaj yeem tiv taus cov xwm txheej no yam tsis muaj degrading lossis melting.
Boron nitride kuj yog ib qho kev xaiv zoo tshaj plaws rau lub foob pob hluav taws, uas yog lub plhaub sab nrauv ntawm lub foob pob hluav taws lub cav thiab tiv thaiv nws cov khoom los ntawm tshav kub thiab lwm yam kev cuam tshuam ib puag ncig. Casings yuav tsum muaj peev xwm tiv taus qhov kub thiab txias, kev kub ntxhov, thiab kev ntxhov siab, thiab yuav tsum muaj zog txaus los tiv thaiv lub cav los ntawm kev tawg lossis ua tsis tiav. Boron nitride lub zog zoo dua, tawv, thiab ruaj khov ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv hauv foob pob hluav taws.
Nyob rau hauv xyoo tsis ntev los no, boron nitride tau siv nyob rau hauv ib tug xov tooj ntawm high-profile foob pob ua ntxaij cav tej yaam num. Piv txwv li, xyoo 2017, NASA tau sim lub tshuab foob pob hluav taws uas muaj lub taub hau ua los ntawm boron nitride nkaus, uas yog ib feem ntawm lub koom haum kev siv zog los tsim cov thev naus laus zis tshiab, muaj txiaj ntsig zoo dua. Lub cav muaj peev xwm ua tiav qib siab uas yog kwv yees li ob zaug ntawm cov tshuab foob pob hluav taws ib txwm muaj, ua tsaug rau ib feem ntawm qhov kev ua tau zoo tshwj xeeb ntawm boron nitride-based nozzle.
Zuag qhia tag nrho, kev siv cov boron nitride hauv cov tshuab foob pob hluav taws sawv cev yog ib kauj ruam tseem ceeb rau pem hauv ntej hauv tshuab foob pob hluav taws. Nws muaj kev sib xyaw ua ke uas tsis tau muaj dua los ntawm lub zog, kav ntev, thiab kev ruaj ntseg, ua rau nws zoo rau kev xav tau ntawm qhov chaw mus ncig. Nrog rau kev tshawb fawb thiab kev loj hlob ntxiv, nws zoo li peb yuav pom ntau qhov kev siv tshiab ntawm cov khoom siv txuj ci tseem ceeb no nyob rau yav tom ntej qhov chaw tshaj tawm txoj moo zoo.
Shengyang New Material Co., Ltd. tau cog lus rau kev tsim cov boron nitride thiab boron nitride ua cov khoom, thiab tuaj yeem kho ntau yam boron nitride insulating ceramic qhov chaw raws li cov neeg siv khoom xav tau. Tiv tauj peb yog tias tsim nyog.
