Mafunso Ofunsidwa KawirikawiriKukana kwa Makoswe a Mitundu Yosiyanasiyana ya Zingwe za Ulusi Wowala
1. Chiyambi
Pakutumiza ndi kukonza chidziwitso, Optical Fiber Cables (OFCs) imagwira ntchito yofunika kwambiri. Amaonedwa kuti ndi misewu yayikulu yolumikizirana ndi ma telematics. Chifukwa chake, ndikofunikira kwambiri kuti atsimikizire kulumikizana kotetezeka nthawi zonse. Komabe, nthawi zina, nthawi yogwira ntchito ya OFC ikhoza kuopsezedwa ndi makoswe, mwachitsanzo pamene ma OFC aikidwa m'mitsempha yomwe makoswe amatha kufikako mosavuta. M'malo otere, ma OFC ayenera kutetezedwa, chifukwa makoswe ali ndi chizolowezi chachilengedwe choluma ndi kuukira ma OFC pamene kutuluka kwawo kwatsekedwa m'mitsempha iyi.
Kuti apange chingwe chabwino kwambiri, opanga chingwe amakonda kugwiritsa ntchito chinthu chomwe chimaphatikiza zinthu zolimbitsa ndi chitetezo cha makoswe. Amafunanso kuti ma OFC akhale osinthasintha komanso opepuka, komanso akhale ndi mainchesi ochepa. Zipangizo zolimbitsa ma OFC a dielectric makamaka ndi aramid ndi E-glass pang'ono. Kugwiritsa ntchito aramid ndikotchuka kwambiri ndipo kukuchulukirachulukira chifukwa cha kuphatikiza kwake kosayerekezeka kwa zinthu zamakanika ndi mankhwala komanso zinthu zake zabwino zokonzera, zomwe zimapangitsa kuti ma OFC akhale otsika mtengo kwambiri okhala ndi magwiridwe antchito abwino komanso odalirika kwa nthawi yayitali. Komabe, funso loti E-glass ndi aramid zimateteza makoswe mokwanira nthawi zambiri lafunsidwa. Zinali zovuta kupeza yankho lomveka bwino kuchokera kwa ogwiritsa ntchito OFC. Mwachitsanzo, zomwe ogwiritsa ntchito OFC adakumana nazo ku Switzerland, zidawonetsa kuti nthawi zina zingwe zonse za E-glass ndi aramid zolimbikitsidwa zidawonongeka kwambiri ndi makoswe kotero kuti sizinagwirenso ntchito bwino. Kuti timvetse bwino momwe zinthu zilili pankhani yoteteza makoswe komanso kuthandizira opanga ma dielectric OFC, tinaganiza mogwirizana ndi m'modzi mwa makasitomala athu aku Switzerland kuti tiitane bungwe lodziyimira pawokha lofufuza, TNO (bungwe la ku Dutch lofufuza zasayansi), kuti lichite kafukufuku pansi pa mikhalidwe yothandiza kuti tiyese kukana makoswe amitundu ingapo ya ma OFC.
2. Kuyesera
Kukhazikitsa mayeso
Pofuna kuyesa kukana kwa makoswe a OFC, TNO idagwiritsa ntchito makoswe a Sprague Dawley omwe adasungidwa m'makhola omwe adapangidwira kafukufukuyu. Makhola awa adagawidwa m'makhola awiri pogwiritsa ntchito gawo lokhala ndi dzenje lozungulira kuti alumikize magawo awiriwa (onani Chithunzi 1). Chigawo chimodzi chidawunikiridwa ndipo chinacho chidadetsedwa. Pa nthawi ya mayesowo, khomo lolowera m'chipinda chamdima, momwe munali chakudya cha makoswe, linatsekedwa ndi ma OFC poyesa. Popeza makoswe amakonda malo amdima, nthawi yawo yambiri amakhala kumbali yamdima. Chifukwa chake, panali zinthu ziwiri zomwe zimapangitsa makoswe kulowa m'chipinda chamdima. Pa nthawi yonse yoyesa makoswe anali ndi mwayi wopeza madzi. Makoswe atazolowera momwe zinthu zilili m'makhola, mayeso oyamba adayamba.
Chithunzi 1: Khola loyesera lagawidwa m'zigawo ziwiri.
Poyamba mayeso, makoswe atatu anaikidwa m'zipinda zowala za khola lililonse kwa masiku awiri otsatira, pomwe dzenje lomwe linali m'chigawocho linatsekedwa ndi kapangidwe ka OFC poyeserera (onani Chithunzi 2). Pambuyo pa nthawiyi makoswewo anasamutsidwira ku zikwama zina kwa masiku anayi kenako n’kubwezeretsedwa ku zikwama zoyesera kwa masiku ena awiri.
Chithunzi 2: Bowo mu gawo lotsekedwa ndi OFCs poyeserera.
Mapangidwe a OFC ayesedwa
Mapangidwe asanu ndi anayi osiyanasiyana a OFC adawunikidwa kuti awone ngati makoswe sakukhudzidwa ndi matendawa. Mapangidwe awa onse ndi gawo la gulu la mapangidwe omwe amawerengera gawo lalikulu la msika wa OFC. Ma OFC akhoza kugawidwa m'magulu awiri:
1. Mapangidwe a OFC okhazikika pogwiritsa ntchito ulusi wa aramid kapena galasi la E (lokhala ndi kapena lopanda impregnation) ngati zinthu zolimbikitsira pansi pa chidebe chakunja cha PE (Zithunzi 3a mpaka 3d).
2. Mapangidwe apadera a OFC kuti apewe kuukira kwa makoswe, mwachitsanzo zomangamanga zokhala ndi zigawo ziwiri kapena zomangamanga zokhala ndi PA12 kapena chitsulo chosungunuka (Zithunzi 3e mpaka 3i).
Chithunzi 3a: Gawo lozungulira la kapangidwe ka OFC kokhazikika. Chithunzi 3b: Gawo lozungulira la kapangidwe ka OFC kokhazikika.
Chithunzi 3c: Gawo lozungulira la kapangidwe ka OFC kokhazikika.Chithunzi 3d: Gawo lozungulira la kapangidwe ka OFC kokhazikika.
Chithunzi 3e: Gawo la mtanda wa kapangidwe kapadera ka OFC.Chithunzi 3f: Gawo la mtanda wa kapangidwe kapadera ka OFC.
Chithunzi 3g: Gawo la mtanda wa kapangidwe kapadera ka OFC.Chithunzi cha 3h: Gawo la mtanda wa kapangidwe kapadera ka OFC.
Chithunzi 3i: Gawo la mtanda wa kapangidwe kapadera ka OFC.
3. Zotsatira ndi zokambirana
Pambuyo pa nthawi ziwiri zoyeserera za masiku awiri, kuwonongeka komwe kudachitika chifukwa cha kuukira kwa makoswe kudawunikidwa. Mu Zithunzi 4a mpaka 4i muwona zithunzi ziwiri za kapangidwe ka chingwe chilichonse choyesedwa; chithunzi chapamwamba chikuwonetsa chosawonongeka kwambiri ndi chapansi chikuwonetsa OFC yowonongeka kwambiri. Zotsatira za kufufuza kwa macroscopic kwa zingwe zikuwonetsa bwino kusiyana kwa kuwonongeka pakati pa mapangidwe asanu ndi anayi a OFC. Koma, monga mukuonera pazithunzi, ma OFC onse - kupatula kapangidwe ka chitsulo cholimba/aramid - awonongeka mwanjira yoti munthu angayembekezere kuti katundu wotumizira nthawi yayitali akhudzidwe. Izi zimagwiranso ntchito pa mapangidwe a OFC PE/galasi lolowetsedwa/tepi yoletsa madzi (Chithunzi 4d) ndi PE/galasi lolowetsedwa/PE/aramid (Chithunzi 4h), ngakhale mapangidwe awa akuwonetsa kuwonongeka kochepa. Komabe, m'machitidwe, munthu amachita ndi makoswe omwe si a m'nyumba, omwe angayambitse kuukira koopsa komanso kosalekeza ngati khoswe wagwidwa. Chifukwa chake, potengera zotsatira za mayeso a TNO, mfundo iyenera kukhala yakuti pa mapangidwe oyesedwa, kapangidwe ka chitsulo/aramid kokha ndi komwe kamalimbana ndi makoswe.
Kukana kwa makoswe a OFC kungawongoleredwenso pogwiritsa ntchito zipolopolo zakunja zopangidwa ndi polyamide kapena polyamide copolymers zopanda mawonekedwe okhala ndi kuuma kwakukulu kwa Shore D. Chifukwa chake, tikupangira opanga mawaya kuti akonze kukana kwa makoswe a OFCs pogwiritsa ntchito chitsulo chopangidwa ndi corrugated steel (monga Zetabon) kapena zipolopolo zopangidwa ndi polyamide kapena polyamide copolymers zopanda mawonekedwe (monga Grilamid). Kugwiritsa ntchito corrugated steel kumawoneka ngati chisankho chabwino kwambiri.
Lingaliro lakuti kukula kwa chingwe kumakhudza kukana kwa makoswe a OFC - zomwe zikutanthauza kuti kuyambira kukula kwa chingwe kupita mtsogolo mphamvu yabwino pa kukana kwa makoswe ikhoza kuchitika - ndi losangalatsa ndipo kafukufuku wowonjezera ungakhale wothandiza kwa opanga ma chingwe.
Chithunzi 4a: Kapangidwe ka chingwe cha PE/aramid pambuyo poyesa; m'mimba mwake 13.5 mm.
Chithunzi 4b: Kapangidwe ka chingwe cha E-glass chopangidwa ndi PE/chodzazidwa pambuyo poyesa; m'mimba mwake ndi 11.8 mm.
Chithunzi 4c: Kapangidwe ka chingwe cha PE/E-glass pambuyo poyesa; m'mimba mwake 9.5 mm.
Chithunzi 4d: Kapangidwe ka chingwe cha PE/galasi la E/lotsekeredwa madzi pambuyo poyesa; m'mimba mwake 15.5 mm.
Chithunzi 4e: Kapangidwe ka chingwe cha PE/galasi la E/PE/aramid chodzazidwa ndi madzi pambuyo poyesa; m'mimba mwake 8.8 mm.
Chithunzi 4f: Kapangidwe ka chingwe cha PE/aramid/PE/aramid pambuyo poyesa; m'mimba mwake 21 mm.
Chithunzi 4g: Kapangidwe ka chingwe cha PE/PA12/aramid pambuyo poyesa; m'mimba mwake 8.5 mm.
Chithunzi cha 4h: Kapangidwe ka chingwe cha PE/galasi la E/aramid chodzazidwa ndi PE/chodzazidwa ndi madzi pambuyo poyesedwa; m'mimba mwake 15.7 mm
Chithunzi 4i: Kapangidwe ka chingwe cha PE/chitsulo cha dzimbiri/PE/aramid pambuyo poyesedwa; m'mimba mwake 14.7 mm.
4. Mapeto
Potengera zotsatira za mayesowa, TNO yatsimikiza kuti mwa mapangidwe a OFC omwe ayesedwa, kapangidwe ka chitsulo/aramid kokha ndi komwe kamalimbana ndi makoswe. Mapangidwe ena onse (olimbikitsidwa ndi galasi la E lomwe lili ndi kapena lopanda impregnation- kapena aramid, kapena ndi chidebe cha PA12) sanathe kukana mokwanira kuukira makoswe. Kafukufukuyu akuwonetsa momveka bwino kuti ngati pakufunika kukana makoswe, munthu ayenera kuyang'anitsitsa kapangidwe ka chingwe.
