Mapulogalamu osindikizidwa pama board ozungulira
Popanga ma board osindikizidwa (omwe amatchedwa PCB), ulusi wa aramid umagwiritsidwa ntchito popanga zida zotsogola zapamwamba kwambiri zamagetsi.Thandizo lamtunduwu limakhala ndi mphamvu zolimba, kotero zimatha kupewa mapepala amkuwa ndi ma resin substrates pambuyo potenthedwa.mavuto kulekana.M'makampani amagetsi, kugwiritsa ntchito zipangizo za aramid kupanga matabwa a PCB kungapangitse mphamvu ndi khalidwe la matabwa a dera.Gulu lozungulira lamtunduwu limakhala ndi kukula bwino komanso gawo lokulitsa la 3×10-6/℃.Chifukwa cha kuchepa kwa dielectric pafupipafupi kwa board board, ndiyoyenera kufalitsa mizere yothamanga kwambiri.
Poyerekeza ndi zipangizo galasi CHIKWANGWANI, unyinji wa bolodi dera ili yafupika ndi 20%, motero kukwaniritsa cholinga kupanga kuwala kulemera ndi dongosolo laling'ono la zipangizo zamagetsi.Kampani ina ya ku Japan yapanga bolodi la PCB lokhazikika bwino, kusinthasintha kwapamwamba, komanso kukana chinyezi champhamvu.Popanga,ulusi wa aramidamagwiritsidwa ntchito mu meta-position, yomwe imafulumizitsa kukonzekera kwa epoxy-based resin resin.Poyerekeza ndi kugwiritsa ntchito zinthu zosiyana, ndizosavuta kuzikonza ndipo zimakhala ndi ntchito yabwino yoyamwitsa chinyezi.Ma PCB opangidwa ndi ma aramid fibers ndi opepuka komanso olimba pakuchita bwino, ndipo amatha kugwiritsidwa ntchito pamafoni ndi makompyuta apakompyuta.Kuphatikiza apo, ma board apano apano otengera ma aramid fiber okhala ndi mitundu ingapo amatha kuyika zida zamagetsi zolimba kwambiri, zomwe ndizoyenera kutumiza mabwalo othamanga kwambiri ndipo akhala akugwiritsidwa ntchito kwambiri m'makampani ankhondo.
Mapulogalamu mu Antenna Components
Chifukwa chakuti zinthu za aramid zili ndi zinthu zabwino za dielectric, zimagwiritsidwa ntchito m'zigawo za radome, zomwe zimakhala zowonda kwambiri kuposa magalasi amtundu wa radome, zolimba bwino komanso kutumizirana ma signal apamwamba.Poyerekeza ndi theka-wavelength radome, radome yomwe ili mu interlayer imagwiritsa ntchito zinthu za aramid kupangazisacholumikizira.Zomwe zili pachimake ndizopepuka komanso zamphamvu kuposa zida zamagalasi.Choyipa chake ndi mtengo wopanga.apamwamba.Choncho, ingagwiritsidwe ntchito popanga zida za radome m'madera apamwamba monga shipboard radar ndi airborne radar.Makampani aku America ndi Japan pamodzi adapanga mlongoti wa radar parabolic, pogwiritsa ntchito zida za para-aramid pamawonekedwe a radar.
Popeza kafukufuku pafiber aramidzida zinayamba mochedwa m'dziko langa, ukadaulo wakula mwachangu.Setilaiti yomwe yapangidwa pano APSTAR-2R imagwiritsa ntchito cholumikizira cha zisa ngati chowunikira cha mlongoti.Zikopa zamkati ndi zakunja za mlongoti zimagwiritsa ntchito zida za para-aramid, ndipo kuphatikizikako kumagwiritsa ntchito zisa za aramid.Popanga ndege ya radome, para-aramid imagwiritsidwa ntchito kupezerapo mwayi pakuyenda bwino kwa mafunde amtunduwu komanso kutsika kwapang'onopang'ono kowonjezera, kotero kuti pafupipafupi kwa chiwonetserochi kumatha kukwaniritsa zofunikira ziwiri za kapangidwe kake ndi ntchito yake. .ESA yapanga chowunikira chamitundu iwiri chokhala ndi mainchesi a 1.1m.Imagwiritsa ntchito mawonekedwe a meta-uchi mumpangidwe wa sangweji ndipo imagwiritsa ntchito zinthu za aramid ngati khungu.Kutentha kwa epoxy resin kapangidwe kake kumatha kufika 25°C ndi dielectric constant ndi 3.46.Zomwe zimatayika ndi 0.013, kutayika kwa chiwonetsero cha ulalo wamtunduwu wamtunduwu ndi 0.3dB yokha, ndipo kutayika kwa chizindikiro ndi 0.5dB.
Chowonetsera chamitundu iwiri chomwe chimagwiritsidwa ntchito mu setilaiti ku Sweden chili ndi mainchesi a 1.42m, kutayika kwa kutumiza kwa <0.25dB, ndi kutayika kowonetsa <0.1dB.Institute of Electronics yakudziko langa yapanga zinthu zofananira, zomwe zimakhala ndi masangweji ofanana ndi tinyanga zakunja, koma zimagwiritsa ntchito zida za aramid ndi zida zamagalasi zophatikizika ngati zikopa.Kutayika kwa chiwonetsero cha mlongoti uwu mu ulalo wotumizira ndi <0.5dB, ndipo kutayika kwapatsira ndi <0.3 dB.

Kuphatikiza pa ntchito zomwe zili pamwambazi, ma aramid fibers amagwiritsidwanso ntchito kwambiri pazinthu zamagetsi monga mafilimu ophatikizika, zingwe zotchingira / ndodo, zowononga ma circuit, ndi mabuleki.Mwachitsanzo: Mu chingwe cholumikizira cha 500kV, gwiritsani ntchito chingwe chotchingira chopangidwa ndi zinthu za aramid m'malo mwa insulating suspender ngati chida chonyamula katundu, ndipo gwiritsani ntchito chingwe chotchingira kuti mulumikizane ndi screw ndodo, yomwe imathandizira kulimbikitsa chitetezo pamwamba pa 3. ndodo imapangidwa makamaka ndi ulusi wa aramid ndi ulusi wa poliyesitala wolumikizana, woyikidwa mu vacuum, womizidwa mu epoxy utomoni wa zinthu, ndikuwumbidwa pambuyo pochiritsa.Ili ndi kukana bwino kwa dzimbiri pakagwiritsidwa ntchito, kulemera kopepuka komanso mphamvu yayikulu, ndipo izi zimakhala ndi ntchito yabwino yotchinjiriza.Mu mzere wa 110kV, kugwiritsa ntchito ndodo zotchingira kumakhala pafupipafupi, ndipo mphamvu yake yamakina imakhala yayikulu mukamagwiritsa ntchito, ndipo imakhala ndi mikhalidwe yabwino yolimbana ndi kutopa.Popanga makina amagetsi, kugwiritsa ntchito zida za aramid fiber kumatha kupititsa patsogolo kulimba kwa zigawo ndikuletsa kuvala kwakukulu pamwamba pazosintha zoumba.Ikhoza kusintha ulusi wagalasi muzipangizo zamagetsi.Ulusi wa ulusi wa aramid ndi 5%, ndipo kutalika kwake kumatha kufika 6.4mm.Mphamvu yamphamvu ndi 28.5MPa, kukana kwa arc ndi 192s, ndipo mphamvu yake ndi 138.68J/m, kotero kukana kuvala ndikokwera.
Komabe mwazonse,zipangizo za aramidamagwiritsidwa ntchito kwambiri pazamagetsi zamagetsi ndi zamagetsi, koma akukumananso ndi zovuta.Dziko liyenera kuchita ntchito monga zosinthira ndi zida zotumizira mphamvu kuti zilimbikitse kulimbikitsa ndi kugwiritsa ntchito zinthu zamtunduwu pakutchinjiriza magetsi, ndikuchepetsa mosalekeza ntchito zaukadaulo ndi zinthu zakunja.kusiyana pakati.Panthawi imodzimodziyo, ntchito zogwira ntchito kwambiri m'mabwalo ozungulira, radar ndi madera ena ziyenera kulimbikitsidwa kuti zipereke masewera athunthu ku ubwino wa ntchito zakuthupi ndikulimbikitsa chitukuko chabwino cha minda yamagetsi yamagetsi ndi magetsi a dziko langa.
