Granite yog cov pob zeb uas tsis muaj zog uas tsim los ntawm quartz, feldspar thiab mica, thiab muaj cov ntawv thov tshwj xeeb hauv kev lag luam aerospace, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv kho qhov muag. Kev siv granite hauv daim teb no yog los ntawm nws cov khoom zoo heev, uas yog qhov tseem ceeb rau qhov tseeb thiab kev ntseeg siab uas yuav tsum tau muaj hauv kev siv aerospace.
Ib qho ntawm granite qhov zoo tshaj plaws yog nws qhov kev ruaj ntseg. Tsis zoo li ntau cov khoom siv hluavtaws, granite muaj qhov thermal expansion tsawg, uas yog ib qho tseem ceeb rau cov khoom siv kho qhov muag uas yuav tsum muaj kev sib raug zoo raws li qhov kub thiab txias. Qhov kev ruaj ntseg no ua kom ntseeg tau tias cov tshuab kho qhov muag xws li telescopes thiab sensors ua haujlwm tau zoo hauv qhov chaw hnyav ntawm qhov chaw.
Tsis tas li ntawd, granite qhov ntom thiab hardness ua rau nws cov khoom siv vibration-damping. Hauv kev siv aerospace, txawm tias qhov kev vibrations me ntsis tuaj yeem ua rau muaj teeb meem loj hauv kev ntsuas qhov muag. Los ntawm kev siv granite ua ib qho chaw muag khoom lossis cov khoom siv rau cov khoom siv kho qhov muag, cov engineers tuaj yeem ua rau cov kev vibrations, yog li txhim kho qhov kev ua tau zoo thiab lub neej ntawm cov cuab yeej.
Granite lub ntuj polishing zog kuj ua lub luag haujlwm tseem ceeb hauv kev siv kho qhov muag. Granite lub ntsej muag du tuaj yeem ua tiav zoo los tsim cov khoom siv kho qhov muag zoo xws li lo ntsiab muag thiab tsom iav, uas yog qhov tseem ceeb rau kev ntes thiab tsom teeb pom kev hauv ntau lub tshuab aerospace. Qhov peev xwm no ua rau granite los tsim cov khoom siv uas ua tau raws li cov kev xav tau nruj ntawm kev siv tshuab thev naus laus zis niaj hnub no.
Hauv cov ntsiab lus, kev siv granite hauv aerospace optics qhia txog cov khoom tshwj xeeb ntawm cov khoom no. Nws ruaj khov, poob siab absorbing zog, thiab zoo polishing muaj peev xwm ua rau nws yog ib qho kev xaiv zoo tshaj plaws los xyuas kom meej qhov tseeb thiab kev ntseeg siab ntawm cov tshuab kho qhov muag hauv qhov xav tau aerospace ib puag ncig. Raws li thev naus laus zis txuas ntxiv mus, granite yuav zoo li tseem yog cov khoom siv tseem ceeb hauv kev txhim kho kev txiav-ntug aerospace optics.
