Hauv kev tshawb xyuas cov ntaub ntawv rwb thaiv tsev zoo tshaj plaws, polycrystalline tau tshwm sim los ua kev sib cav sib ceg rau lawv cov khoom siv thermal thermal rwb thaiv tsev. Hauv tsab xov xwm no, peb yuav delve rau hauv cov ntawv thov thiab ua kom zoo dua ntawm polycrystalline fibers nyob hauv thaj teb ntawm thermal rwb thaiv tsev.
Cov khoom muaj txiaj ntsig ntawm polycrystalline fibers:
Cov ntaub ntawv polycrystalline ua los ntawm polycrystalline alumina hais, nthuav qhia qhov khoom siv thermal heev uas ua rau lawv cov ntaub ntawv rwb thaiv tsev. Cov hauv qab no yog qhov tseem ceeb ntawm polycrystalline fibers:
1.Tuagow Thermal conductivity:
Polycrrystalline Fiber Qhia pom tias muaj qhov tsis tshua muaj cua sov qis heev, ua tau zoo qeeb ntawm cov txheej txheem kub hloov. Qhov no ua rau lawv zoo rau cov kev siv uas rwb thaiv tsev thermal uas tseem ceeb heev, xws li cov pa taws kub high-rwb thaiv tsev.
2.High-kub stability:
Cov fibrrystalline fibers ua yeeb yam ua tau zoo ntawm kev kub siab, tswj lawv cov khoom insulating stably. Qhov no ua rau lawv xaiv qhov zoo tshaj plaws rau kev lag luam ua haujlwm nyob rau hauv cov kev mob siab heev.
3.Corrosion Kuj:
Vim tias thawj qhov sib xyaw ntawm polycrystalline fibers yog alumina, lawv qhia tau zoo corrosion zoo heev. Qhov no ua rau lawv haum rau ib puag ncig raug rau corrosive gases lossis tshuaj lom neeg.
4.Thaum thiab lub zog siab:
Cov poj niam polycrystalline yog lub teeb ci tseem tsis tau muaj lub zog siab, muab cov khoom siv siab thiab yooj yim ntawm kev ua. Qhov no yog qhov tseem ceeb rau cov phiaj xwm xav tau yooj yim hauv cov qauv lossis cov duab tshwj xeeb.
Cov ntawv thov ntawm polycrystalline fibers:
Polycrystalline Fibers Nrhiav cov ntawv thov thoob plaws vim lawv cov khoom siv thermal rwb thaiv tsev:
1.Nthaum rauv taws rwb thaiv tsev:
Cov fibresstalline fibers yog qhov dav siv rau rwb thaiv tsev rau cov cua sov, ua kom muaj zog txo cov hluav taws xob hluav taws xob thiab txhim kho hluav taws xob ua haujlwm.
2.Pipeline Rwb thaiv tsev:
Hauv kev lag luam cuam tshuam nrog cov kav dej siab, polycrystalline ua haujlwm ua cov khoom siv thermal zoo tshaj plaws, pab tswj qhov chaw kub khov sab hauv cov kav dej.
3.Aerospace cov ntawv thov:
Lub teeb ci ntsa iab thiab kev ruaj ntseg siab ntawm polycrystalline fibers ua rau lawv cov khoom siv uas nyiam dua rau kev siv hluav taws xob, nrog phab ntsa thiab rwb thaiv tsev.
Xaus:
Polycrystalline fibers, nrog lawv qhov tshwj xeeb thermal rwb thaiv tsev zog, tab tom dhau los ua kev xaiv ua hauv thaj teb ntawm cov rwb thaiv tsev. Hla ntau txoj kev lag luam thiab thev naus laus zis, polycrystalline fibers ua si ib qho tseem ceeb hauv kev txhim kho kev ua haujlwm, thiab ua kom muaj kev nyab xeeb.
