Vim li cas thiaj tuaj yeem siv Boron Nitride los ua Ib Lub Cuab Yeej Cuab Yeej rau Spacecraft

Boron Nitride yog cov khoom siv zoo heev uas tau pom dav siv los ua cov ntaub thaiv npog thermal hauv lub dav hlau. Qhov no feem ntau yog vim nws qhov tshwj xeeb lub cev thiab cov khoom siv tshuaj lom neeg uas ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv nyob rau hauv qhov hnyav, qhov kub thiab txias.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm Boron Nitride yog nws qhov siab melting point. Thaum kub nce mus txog 3000 degree, cov khoom no pib mos, tab sis tsuas yog maj mam. Qhov no txhais tau hais tias nws tuaj yeem tiv taus cov cua sov uas tsim los thaum huab cua rov nkag, ib qho kev ua yeeb yam uas ob peb lwm cov ntaub ntawv tuaj yeem phim. Tsis tas li ntawd, Boron Nitride yog ib qho zoo heev conductor ntawm tshav kub, tso cai rau nws sai sai thiab zoo dissipate lub tshav kub generated thaum rov nkag.

Lwm cov cuab yeej tseem ceeb ntawm Boron Nitride yog nws lub peev xwm tiv taus siab thiab kev ntxhov siab. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv cov ntawv thov uas yuav tsum muaj kev kub ntxhov thiab kev ntxhov siab, xws li thaum tawm mus thiab tsaws. Tsis tas li ntawd, Boron Nitride muaj kev tiv thaiv zoo rau corrosion thiab oxidation, uas ua kom ntseeg tau tias nws tseem siv tau rau lub sijhawm ntev.

Thaum kawg, Boron Nitride yog ib qho khoom siv tau yooj yim thiab ua haujlwm tau zoo uas tuaj yeem ua tau zoo li tus thiab molded rau hauv cov duab nyuaj thiab teeb tsa. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv kev siv dav hlau, qhov twg cov duab thiab cov qauv tsim feem ntau xav tau.

Hauv kev xaus, Boron Nitride yog cov khoom tseem ceeb uas muaj kev sib xyaw ua ke ntawm cov khoom uas ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv nyob rau hauv lub tshav dav hlau thermal shields. Nrog nws muaj peev xwm tiv taus qhov kub thiab txias, kev kub ntxhov, thiab kev ntxhov siab, ua ke nrog nws cov thermal conductivity zoo heev thiab tiv thaiv corrosion thiab oxidation, Boron Nitride yog ib qho kev xaiv meej rau txhua daim ntawv thov dav hlau uas xav tau cov ntaub thaiv npog thermal.

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.
