Kev koom tes ntawm Boron Nitride rau Aerospace
Oct 30, 2023
Boron nitride thiab nws txoj kev koom tes rau kev lag luam aerospace
Hauv ntiaj teb dav dav ntawm aerospace, qhov chaw muaj kev nyab xeeb, kev cia siab, thiab kev ua tau zoo yog qhov tseem ceeb, kev siv cov khoom siv siab heev yog qhov tseem ceeb. Ntawm cov ntaub ntawv no, boron nitride tau tshwm sim los ua ntau yam khoom siv thiab ntau yam uas tau ua rau muaj txiaj ntsig zoo rau thaj chaw.
Boron nitride muaj cov thermal shock tsis txaus, siab thermal conductivity, thiab zoo heev hluav taws xob rwb thaiv tsev zog, ua rau nws yog ib qho zoo tagnrho xaiv rau ntau yam aerospace daim ntaub ntawv. Nws siv los ua cov khoom siv substrate rau microelectronics ntim, kev tiv thaiv thermal, thiab kev sib xyaw ua ke tau ua rau muaj kev cuam tshuam hauv kev tshawb nrhiav chaw, tsim dav hlau, thiab ntau ntxiv.
Ib qho tseem ceeb ntawm daim ntawv thov ntawm boron nitride yog nyob rau hauv kev tsim kho ntawm reusable spacecraft, qhov twg nws muab cov kev pab cuam tseem ceeb nyob rau hauv daim ntawv ntawm kev txhim kho tshav kub tswj thiab kev tiv thaiv. Raws li ib qho insulator, boron nitride tuaj yeem siv los ua cov txheej txheem los tiv thaiv thermal shock, thaum nws cov thermal conductivity siab tso cai rau nws kom tshem tawm cov cua sov kom zoo. Nws kuj yog siv los ua ib feem ntawm lub teeb yuag, muaj zog sib xyaw cov ntaub ntawv hauv cov qauv dav hlau, txo qhov hnyav thiab nce roj efficiency.
Lwm qhov txiaj ntsig tseem ceeb ntawm boron nitride yog nws lub peev xwm los tiv thaiv qhov kub thiab txias ib puag ncig. Nws yog resistant rau feem ntau cov tshuaj, hluav taws xob, thiab txawm ua ib tug lubricant nyob rau hauv high-temperature daim ntaub ntawv. Cov khoom no yog qhov tseem ceeb hauv kev txhim kho qhov chaw sojntsuam, satellites, thiab lwm yam khoom siv dav hlau, uas cov ntaub ntawv yuav raug tshav kub, txias, thiab hluav taws xob.
Tsis tas li ntawd, boron nitride kuj tseem siv tau los ua kom muaj txiaj ntsig thiab kev ua neej nyob ntawm cov roj turbines los ntawm kev txo qhov tsim cov kua qaub thiab coke deposits, uas tuaj yeem cuam tshuam kev ua haujlwm ntawm lub cav. Qhov kev nce hauv kev ua tau zoo no txhais tau tias txo qis hauv cov pa roj carbon monoxide, ua rau boron nitride yog cov khoom siv hauv eco hauv ntiaj teb niaj hnub no.
Hauv cov ntsiab lus, boron nitride tau ua pov thawj tias yog cov khoom siv tseem ceeb hauv kev lag luam aerospace, ua rau kev tsim kom muaj kev nyab xeeb dua, muaj txiaj ntsig zoo dua, thiab txhim khu kev qha ntau lub dav hlau thiab dav hlau. Nws txoj kev koom tes rau kev lag luam yog qhov tseem ceeb thiab yuav txuas ntxiv mus tshawb nrhiav thiab tsim kho yav tom ntej.
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.
