Mu ma network amakono olumikizirana, kaya m'malo oikamo zinthu zakunja kapena makina olumikizirana a fiber optic amkati, kukhazikika kwa nthawi yayitali kwa zingwe zowunikira kumadalira kwambiri chinthu chofunikira cholimbitsa zingwe—ulusi wa aramid. Ndi mawonekedwe ake opepuka, mphamvu yayikulu yolumikizirana, komanso kusinthasintha kwabwino kwa chilengedwe, ulusi wa aramid umagwiritsidwa ntchito kwambiri mu zingwe za ADSS, zingwe za FTTH fiber optic, zingwe zamkati zolumikizirana, ndi zingwe zosiyanasiyana zolumikizirana, komwe umagwira ntchito ngati gawo lofunikira kwambiri lolimbitsa zingwe, zomwe zimapangitsa kuti ikhale gawo lofunikira kwambiri pazinthu zamakono zolumikizirana.
1. Ulusi wa Aramid: Chipangizo Cholimba Kwambiri Chothandizira Kulimbitsa Chingwe
Ulusi wa Aramid ndi ulusi wa polyamide wonunkhira bwino kwambiri. Mu makampani opanga zingwe zowunikira, ulusi wa aramid wokhala ndi modulus wambiri nthawi zambiri umakonzedwa kukhala ulusi wa aramid, womwe umagwiritsidwa ntchito kulimbitsa mphamvu yokoka komanso kukhazikika kwa kapangidwe ka zingwe zowunikira.
Poyerekeza ndi zipangizo zolimbitsa zitsulo zachikhalidwe, ulusi wa aramid umakhala wopepuka komanso wamphamvu kwambiri. Kuchuluka kwake ndi gawo limodzi mwa magawo asanu okha a waya wachitsulo, pomwe mphamvu yake yeniyeni ndi yayikulu kwambiri kuposa yachitsulo. Izi zimathandiza kuti ichepetse kulemera kwa chingwe chonse pamene ikuperekabe chithandizo chodalirika chamakina, zomwe zimapangitsa kuti ikhale chinthu chabwino kwambiri cholimbitsa chingwe cha kuwala.
Kuphatikiza apo,ulusi wa aramidIli ndi modulus yolimba kwambiri komanso yocheperako, zomwe zimathandiza kuchepetsa kupsinjika kwa makina komwe kumapita ku ulusi wa kuwala. Izi zimathandiza kuchepetsa kutayika kwa ma micro-bending ndi kuchepetsa chizindikiro. Monga chingwe cha kuwala chogwira ntchito bwino, ulusi wa aramid umaperekanso kukhazikika kwa kutentha, kukana ukalamba, kukana dzimbiri kwa mankhwala, komanso mphamvu zabwino kwambiri zotetezera kutentha. Ilibe zigawo zachitsulo ndipo motero imachotsa chiopsezo cha dzimbiri, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito kwa nthawi yayitali mu zingwe zolumikizirana.
2. Zingwe za ADSS: Ulusi wa Aramid wopangira malo amlengalenga aatali
Mu gawo la kulumikizana kwa magetsi, chingwe cha ADSS (All-Dielectric Self-Supporting) ndi chimodzi mwa zinthu zofunika kwambiri pa ulusi wa aramid. Popeza zingwe za ADSS zimayikidwa m'mizere yotumizira mphamvu yamagetsi amphamvu kwambiri kwa nthawi yayitali, zimafuna zipangizo zolimbitsa chingwe zomwe zimakhala ndi mphamvu yokoka komanso zoteteza kutentha.
Mu kapangidwe ka chingwe cha ADSS, ulusi wa aramid wamphamvu kwambiri nthawi zambiri umagwiritsidwa ntchito ngati chinthu chachikulu cholimbikitsira kuti chipirire katundu wa mphepo, kulemera kwake, ndi kupsinjika kwa span. Poyerekeza ndi kapangidwe kachitsulo kothandizira, ulusi wa aramid ndi wopepuka kwambiri ndipo supanga mphamvu yoyambitsa, zomwe zimapangitsa kuti ukhale woyenera kwambiri pa malo amphamvu amphamvu kwambiri.
Mwa kusintha kapangidwe ndi kuchuluka kwa ulusi wa aramid, zingwe za ADSS zitha kupangidwa kuti zigwirizane ndi ma span osiyanasiyana komanso zofunikira pa mphamvu ya makina. Chifukwa chake, zimagwiritsidwa ntchito kwambiri m'madera amapiri, m'malo owolokera mitsinje, komanso m'njira zolumikizirana zamagetsi zomwe zimatumizidwa kutali.
3. Zingwe Zowunikira Zamkati: Kukonza Kusinthasintha ndi Kukhazikika kwa Kukhazikitsa
Poyerekeza ndi zingwe za ADSS, zingwe zowunikira zamkati zimayang'ana kwambiri kusinthasintha ndi kukana kupindika. M'malo monga malo osungira deta, ma netiweki a FTTH, ndi makina olumikizirana, zingwe nthawi zambiri zimapindika pafupipafupi ndikuyika ma conduit, zomwe zimapangitsa kuti zinthu zolimbitsa chingwe zikhale zofunika kwambiri.
Zingwe zodziwika bwino zamkati, monga zingwe za GJPFJV, zimakhala ndi kapangidwe ka "ulusi wothina + ulusi wolimbitsa ulusi wa aramid + chigoba chakunja". Mu kapangidwe kameneka, ulusi wa aramid umagwiritsidwa ntchito kuyamwa mphamvu zomangika ndi kupsinjika kwa makina akunja, kuteteza ulusi wa kuwala ndikuwonjezera kukhazikika kwa kutha.
Chifukwa cha kusinthasintha kwake kwabwino komanso magwiridwe antchito a makina, ulusi wa aramid umachepetsa kuwonongeka komwe kumachitika chifukwa chopindika panthawi yoyika ndikugwiritsa ntchito, zomwe zimapangitsa kuti zingwe zowunikira zamkati zikhale zolimba kwa nthawi yayitali. Chifukwa cha izi, zakhala chinthu chofunikira kwambiri m'makina amakono amagetsi owunikira amkati.
Mapeto
Monga chinthu chofunikira kwambiri cholimbitsa chingwe cha kuwala, ulusi wa aramid umagwiritsidwa ntchito kwambiri mu zingwe za ADSS, zingwe zamkati, zingwe za FTTH, ndi machitidwe osiyanasiyana a zingwe zolumikizirana. Ndi kapangidwe kake kopepuka, mphamvu yayikulu yolimba, kukana kwachilengedwe, komanso magwiridwe antchito okhazikika amakina, ulusi wa aramid umagwira ntchito yofunika kwambiri pakukweza kudalirika kwa chingwe komanso kukhazikika kwa ntchito kwa nthawi yayitali. Kwa opanga zingwe za kuwala, kusankha ulusi wapamwamba wa aramid ndikofunikira kwambiri kuti zitsimikizire kuti chingwe chikugwira ntchito bwino komanso nthawi yayitali yogwirira ntchito.
