Hauv kev tshawb nrhiav qhov zoo tshaj plaws thermal rwb thaiv tsev cov ntaub ntawv, polycrystalline fibers tau tshwm sim los ua ib tug neeg sib tw, garnering dav saib rau lawv tshwj xeeb thermal rwb thaiv tsev zog. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv daim ntawv thov thiab superior yam ntxwv ntawm polycrystalline fibers nyob rau hauv lub tshav pob ntawm thermal rwb thaiv tsev.
Unique Properties ntawm Polycrystalline Fibers:
Polycrystalline fibers yog cov ntaub ntawv fiber ntau ua los ntawm polycrystalline alumina hais, nthuav tawm cov thermal conductivity tsawg heev uas ua rau lawv cov ntaub ntawv rwb thaiv tsev zoo heev. Cov hauv qab no yog cov yam ntxwv tseem ceeb ntawm polycrystalline fibers:
1. Tsawg Thermal Conductivity:
Polycrystalline fibers ua kom pom qhov tsis tshua muaj thermal conductivity, ua kom qeeb ntawm cov txheej txheem hloov hluav taws xob. Qhov no ua rau lawv ua tau zoo nyob rau hauv cov ntawv thov uas muaj txiaj ntsig thermal rwb thaiv tsev yog qhov tseem ceeb, xws li kub-kub rauv hauv ob sab phlu thiab cov raj xa dej.
2.High-kub Stability:
Polycrystalline fibers muaj kev ua tau zoo heev ntawm qhov kub thiab txias, tswj lawv cov khoom insulating ruaj khov. Qhov no ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev lag luam ua haujlwm nyob rau hauv qhov kub thiab txias.
3. Corrosion Resistance:
Vim lub ntsiab muaj pes tsawg leeg ntawm polycrystalline fibers yog alumina, lawv qhia zoo heev corrosion kuj. Qhov no ua rau lawv haum rau ib puag ncig uas raug corrosive gases lossis tshuaj lom neeg.
4. Lub teeb yuag thiab siab zog:
Polycrystalline fibers yog lub teeb yuag tsis tau muaj lub zog siab, muab kev yoog raws thiab yooj yim ntawm kev ua haujlwm. Qhov no yog ib qho tseem ceeb heev rau tej yaam num uas xav tau kev hloov pauv hauv cov qauv lossis cov kev xav tau tshwj xeeb.
Kev siv ntawm Polycrystalline Fibers:
Polycrystalline fibers pom ntau daim ntawv thov vim lawv cov thermal rwb thaiv tsev zoo:
1.Industrial Rauv Rwb thaiv tsev:
Polycrystalline fibers yog dav siv rau rwb thaiv tsev nyob rau hauv high-temperature industrial furnaces, zoo txo thermal zog poob thiab txhim kho lub zog efficiency.
2. Pipeline rwb thaiv tsev:
Hauv kev lag luam uas cuam tshuam nrog cov kav dej kub kub, polycrystalline fibers ua cov khoom siv thermal rwb thaiv tsev zoo tshaj plaws, pab tswj qhov kub thiab txias hauv cov kav dej.
3.Aerospace Applications:
Lub teeb yuag thiab kub ruaj khov ntawm polycrystalline fibers ua rau lawv nyiam cov khoom siv rau kev siv dav hlau, nrog rau cov phab ntsa hauv tsev thiab cov foob pob hluav taws.
Xaus:
Polycrystalline fibers, nrog rau lawv cov khoom tshwj xeeb thermal rwb thaiv tsev, maj mam dhau los ua ib qho kev xaiv hauv kev thermal rwb thaiv tsev. Thoob plaws ntau yam kev lag luam thiab thev naus laus zis, polycrystalline fibers ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm, txo kev siv hluav taws xob, thiab ua kom muaj kev nyab xeeb.
