Ndi kupita patsogolo kwa kusintha kwa digito ndi luntha la anthu, kugwiritsa ntchito zingwe zowunikira kukufalikira kwambiri. Ulusi wowala, monga njira yotumizira uthenga mu zingwe zowunikira, umapereka kufalikira kwa bandwidth yayikulu, liwiro lalikulu, komanso kuchedwa kochepa. Komabe, ndi mainchesi a 125μm okha komanso opangidwa ndi ulusi wagalasi, ndi ofooka. Chifukwa chake, kuti zitsimikizire kuti kufalikira kwa ulusi wowala kuli kotetezeka komanso kodalirika m'malo osiyanasiyana monga nyanja, nthaka, mpweya, ndi malo, zipangizo zapamwamba za ulusi ndizofunikira ngati zida zolimbikitsira.
Ulusi wa Aramid ndi ulusi wopangidwa ndi ukadaulo wapamwamba womwe wasintha kuyambira pomwe unayamba kugwiritsidwa ntchito m'mafakitale m'ma 1960. Ndi maulendo angapo, wapanga mndandanda ndi mafotokozedwe osiyanasiyana. Makhalidwe ake apadera—kulemera kopepuka, kusinthasintha, mphamvu yayikulu yolimba, modulus yayikulu yolimba, kukulitsa kotsika kwa mzere, komanso kukana bwino chilengedwe—kumapangitsa kuti ikhale chinthu choyenera cholimbikitsira zingwe zamagetsi.
1. Zipangizo zopangira zingwe zowala
Zingwe zowunikira zimakhala ndi pakati polimbikitsidwa, pakati pa chingwe, m'chimake, ndi gawo loteteza lakunja. Kapangidwe ka pakati kakhoza kukhala kokhala ndi pakati pa chimodzi (mitundu yolimba ndi yolumikizidwa ndi chubu) kapena kokhala ndi pakati pambiri (mitundu yosalala ndi yolumikizidwa). Gawo loteteza lakunja likhoza kukhala lotetezedwa ndi zitsulo kapena losakhala lachitsulo.
2. Kapangidwe ka Aramid Fiber mu Zingwe Zowala
Kuyambira mkati mpaka kunja, chingwe chowunikira chimaphatikizapoulusi wowala, chubu chomasuka, chotchingira kutentha, ndi chivundikiro. Chubu chomasuka chimazungulira ulusi wowala, ndipo malo pakati pa ulusi wowala ndi chubu chomasuka amadzazidwa ndi gel. Chivundikirocho chimapangidwa ndi aramid, ndipo chivundikiro chakunja ndi chivundikiro cha polyethylene chopanda utsi wambiri, chopanda halogen, chomwe chimaphimba chivundikiro cha aramid.
3. Kugwiritsa Ntchito Aramid Fiber mu Zingwe Zowala
(1) Zingwe Zowunikira Zamkati
Zingwe zofewa za kuwala za single- ndi double-core zimadziwika ndi bandwidth yayikulu, liwiro lalikulu, komanso kutayika kochepa. Zimagwiritsidwa ntchito kwambiri m'malo osungira deta, zipinda za seva, ndi mapulogalamu a fiber-to-the-desk. Mu ma network a mobile broadband omwe amagwiritsidwa ntchito kwambiri, malo ambiri oyambira ndi makina ogawa nthawi mkati amafunikira kugwiritsa ntchito zingwe zowala zakutali ndi zingwe zowala za micro-optical hybrid. Kaya ndi zingwe zofewa za single- kapena double-core kapena zingwe zowala zakutali ndi zingwe zowala za micro-optical hybrid, kugwiritsa ntchito zingwe zowala zamphamvu kwambiri, zapamwamba, komanso zosinthasintha.ulusi wa aramidmonga chinthu cholimbikitsira chimaonetsetsa kuti chitetezo cha makina, kuchedwa kwa moto, kukana chilengedwe, komanso kutsatira zofunikira za chingwe.
(2) Chingwe Chodzithandizira Chokha cha Dielectric (ADSS) Chonse
Ndi chitukuko chofulumira mu zomangamanga zamagetsi ku China komanso mapulojekiti amphamvu kwambiri, kuphatikiza kwakukulu kwa maukonde olumikizirana magetsi ndi ukadaulo wa 5G ndikofunikira kwambiri pakupanga ma gridi anzeru. Zingwe zowunikira za ADSS zimagwiritsidwa ntchito m'mizere yamagetsi, zomwe zimafuna kuti zizigwira ntchito bwino m'malo okhala ndi ma electromagnetic field ambiri, kuchepetsa kulemera kwa chingwe kuti zichepetse katundu pamizere yamagetsi, ndikupanga kapangidwe ka dielectric yonse kuti zisawombere mphezi ndikuwonetsetsa kuti ndi otetezeka. Ulusi wa aramid wamphamvu kwambiri, wokwera modulus, komanso wocheperako umateteza bwino ulusi wowunikira mu zingwe za ADSS.
(3) Zingwe Zolumikizidwa ndi Optoelectronic Composite
Zingwe zolumikizidwa ndi zinthu zofunika kwambiri zomwe zimalumikiza nsanja zowongolera ndi zida zowongolera monga mabaluni, zombo za ndege, kapena ma drone. Munthawi ya chidziwitso chofulumira, kusintha kwa digito, ndi luntha, zingwe zolumikizira zamagetsi ziyenera kupereka mphamvu zamagetsi komanso kutumiza chidziwitso mwachangu kwambiri pazida zamakompyuta.
(4) Zingwe Zoyendera za Mafoni
Zingwe zoyendera zamagetsi zimagwiritsidwa ntchito makamaka pazochitika zakanthawi zolumikizirana, monga minda yamafuta, migodi, madoko, mawailesi apawailesi yakanema, kukonza mizere yolumikizirana, kulumikizana mwadzidzidzi, kukana zivomerezi, komanso kuthandiza pakagwa masoka. Zingwezi zimafuna kulemera kopepuka, mainchesi ang'onoang'ono, komanso kusunthika, pamodzi ndi kusinthasintha, kukana kuwonongeka, kukana mafuta, komanso kukana kutentha kochepa. Kugwiritsa ntchito ulusi wosinthasintha, wamphamvu kwambiri, komanso wokwera modulus aramid ngati mphamvu kumathandizira kukhazikika, kukana kuthamanga, kukana kuwonongeka, kukana mafuta, kusinthasintha kutentha kochepa, komanso kuchedwa kwa moto kwa zingwe zoyendera zamagetsi.
(5) Zingwe Zowongolera Zowongolera
Ulusi wa kuwala ndi wabwino kwambiri potumiza uthenga mwachangu, bandwidth yotakata, kukana kusokonezedwa kwa maginito, kutayika kochepa, komanso mtunda wautali wotumizira mauthenga. Makhalidwe amenewa amawapangitsa kuti azigwiritsidwa ntchito kwambiri m'makina owongolera mawaya. Pa zingwe zowongolera ma missile, ulusi wa aramid umateteza ulusi wofooka wa kuwala, kuonetsetsa kuti umagwiritsidwa ntchito mwachangu ngakhale panthawi youluka missile.
(6) Zingwe Zoyikira Zinthu Zotentha Kwambiri mu Aerospace
Chifukwa cha makhalidwe awo abwino monga mphamvu yayikulu, modulus yapamwamba, kuchepa kwa kachulukidwe, kuchedwa kwa malawi, kukana kutentha kwambiri, komanso kusinthasintha, ulusi wa aramid umagwiritsidwa ntchito kwambiri mu zingwe zamlengalenga. Mwa kuyika ulusi wa aramid ndi zitsulo monga zinc, siliva, aluminiyamu, nickel, kapena mkuwa, ulusi wa aramid woyendetsa umapangidwa, womwe umapereka chitetezo chamagetsi komanso chitetezo chamagetsi. Ulusi uwu ungagwiritsidwe ntchito mu zingwe zamlengalenga ngati zinthu zotetezera kapena zigawo zotumizira chizindikiro. Kuphatikiza apo, ulusi wa aramid woyendetsa umatha kuchepetsa kulemera kwambiri pamene ukuwonjezera magwiridwe antchito, kuthandizira chitukuko cha kulumikizana kwa microwave, zingwe za RF, ndi mapulojekiti ena oteteza ndege. Ulusi uwu umaperekanso chitetezo chamagetsi m'malo opindika pafupipafupi m'zingwe zamagetsi zotera ndege, zingwe zamlengalenga, ndi zingwe za robotic.
