1. Chivundikiro chakunja:
1. Jekete lakunja la zingwe zowunikira zamkati nthawi zambiri limapangidwa ndi polyvinyl chloride (PVC), polyethylene, kapena polyurethane yoletsa moto (LSZH). Jekete ili ndi losalala, lonyezimira, losinthasintha, komanso losavuta kuchotsa. Jekete lakunja la zingwe zowunikira zosalimba lili ndi mawonekedwe oipa ndipo limakonda kumamatira ku ulusi wolimba komanso wa aramid.
2. Chigoba chakunja cha zingwe zowunikira zakunja chiyenera kupangidwa ndi polyethylene yakuda yapamwamba kwambiri (HDPE, MDPE). Chingwecho chikapangidwa, chigoba chakunja chiyenera kukhala chosalala, chonyezimira, chokhuthala mofanana, komanso chopanda thovu. Chigoba chakunja cha zingwe zowunikira zosalimba chimapangidwa makamaka ndi zinthu zobwezerezedwanso. Chigoba chakunja cha zingwe zowunikira zosalimba chimakhala cholimba chifukwa cha kuchuluka kwa zinyalala (fumbi la laimu) mu zipangizo zopangira, zomwe zimapangitsa kuti pakhale mabowo ang'onoang'ono ambiri mu chigoba chakunja cha chingwecho. Ngati chigoba chakunja cha chingwe chowunikira chipindidwa mobwerezabwereza, chidzawonongeka ndikukhala choyera. Chigoba cha kuwala chitayikidwa kwa nthawi ndithu, chigoba chakunja chidzasweka ndikulola madzi kulowa.
2. Ma fiber optics:
Opanga zingwe zowunikira wamba amagwiritsa ntchito ma fiber cores a Class A ochokera kwa opanga otsogola. Zingwe zowunikira zotsika mtengo komanso zotsika mtengo nthawi zambiri zimagwiritsa ntchito ulusi wa Class C, Class D, ndi zinthu zobisika zomwe sizikudziwika komwe zimachokera. Ulusi uwu uli ndi magwero ovuta ndipo wakhala kunja kwa fakitale kwa nthawi yayitali. Nthawi zambiri umakhala wonyowa komanso wosintha mtundu, ndipo ulusi wa multimode nthawi zambiri umasakanizidwa ndi ulusi wa single-mode. Mafakitale ang'onoang'ono nthawi zambiri sakhala ndi zida zoyesera zofunika ndipo sangathe kuwunika mtundu wa ulusi. Ulusi uwu sungadziwike ndi maso. Mavuto omwe amakumana nawo popanga ndi awa: bandwidth yopapatiza kwambiri komanso mtunda waufupi wotumizira; makulidwe osafanana, kuletsa kulumikizana ndi pigtail; komanso kusowa kusinthasintha, zomwe zimapangitsa kuti ulusiwo usweke nthawi zambiri ukazungulira.
3. Waya wolimbitsa chitsulo:
Mawaya achitsulo omwe ali mu zingwe zodziwika bwino za fiber optic zakunja amakhala ndi phosphate ndipo ali ndi pamwamba pa imvi. Mtundu uwu wa waya wachitsulo suwonjezera kutayika kwa haidrojeni pambuyo poyika, suchita dzimbiri, ndipo uli ndi mphamvu yolimba kwambiri. Zingwe za fiber optic zosalimba kwambiri zimapangidwa makamaka ndi zingwe zopyapyala zachitsulo kapena aluminiyamu. Izi zitha kuzindikirika ndi mawonekedwe awo oyera komanso kuti zimatha kupindika mosavuta zikagwidwa m'manja. Zingwe za fiber optic zopangidwa ndi mitundu iyi ya zingwe zachitsulo zidzapangitsa kutayika kwina kwa haidrojeni mtsogolo, ndipo pakapita nthawi, malekezero awiri a mabokosi a fiber optic adzasungunuka ndikusweka.
4. Lamba wachitsulo wotetezedwa ndi zida:
Opanga zinthu wamba amagwiritsa ntchito zingwe zachitsulo zokulungidwa ndi pulasitiki yokhala ndi mbali ziwiri, yopakidwa burashi, komanso yosagwira dzimbiri. Zingwe zowala zosalimba zimapangidwa ndi mapepala wamba achitsulo, ndipo nthawi zambiri mbali imodzi yokha ndi yomwe imakonzedwa kuti ipewe dzimbiri.
5. Chikwama cha kuwala kwa fiber:
Chubu chosasunthika chozungulira ulusi wa kuwala mu chingwe chowunikira chiyenera kupangidwa ndi zinthu za PBT. Zinthuzi zimakhala ndi mphamvu zambiri, sizimasinthasintha, ndipo sizimakalamba. Zingwe zowunikira zosalimba nthawi zambiri zimapangidwa ndi PVC. M'mimba mwake wakunja kwa zingwezi ndi woonda kwambiri komanso wofewa, zimaphwanyika mosavuta zikamakanidwa. Zili ngati udzu wothira madzi ndipo sizipereka chitetezo chokwanira ku ulusi wa kuwala.
6. Mafuta a ulusi:
Ufa wopangidwa ndi ulusi womwe umagwiritsidwa ntchito mu zingwe zakunja za kuwala ungalepheretse kusweka kwa siliva, kutayika kwa haidrojeni, komanso kusweka kwa ulusi wopangidwa ndi kuwala komwe kumachitika chifukwa cha chinyezi. Ufa wopangidwa ndi ulusi wochepa kwambiri umagwiritsidwa ntchito mu zingwe za kuwala zosalimba, ndipo thovu lina limatha kuwoneka ndi maso. Kapenanso, ufa wopangidwa ndi ulusi wosalimba umagwiritsidwa ntchito, zomwe zimafupikitsa kwambiri moyo wa zingwe za kuwala.
7. Aramid:
Ulusi wa aramid womwe umadziwikanso kuti Kevlar, ndi ulusi wa mankhwala amphamvu kwambiri womwe umagwiritsidwa ntchito makamaka m'makampani ankhondo. Umagwiritsidwa ntchito popanga zipewa zankhondo ndi ma vesti osalowa zipolopolo. Pakadali pano, ulusi wa aramid womwe uli pamsika umachokera makamaka ku kampani yaku America ya DuPont. Zingwe zamagetsi zamkati ndi zakunja (ADSS) zimagwiritsa ntchito ulusi wa aramid ngati chowonjezera. Chifukwa cha mtengo wokwera wa aramid (200,000 yuan/tani), zingwe zamagetsi zamkati zotsika mtengo nthawi zambiri zimakhala ndi mainchesi ochepa kwambiri akunja, zomwe zimatha kusunga ndalama pochepetsa kuchuluka kwa ulusi wa aramid womwe umagwiritsidwa ntchito. Mtundu uwu wa chingwe chowunikira umawonongeka mosavuta ukadutsa mumsewu.
8. Chingwe chopachika:
Ulusi wakunja wa chingwe cha fiber optic umalumikizidwa kunja kwa chivundikiro cha fiber optic kuti uteteze chingwecho ku chinyezi. Ulusi wapamwamba kwambiri umasakanikirana mofanana ndipo sumalekanitsidwa ukagwiritsidwa ntchito kwa nthawi yayitali. Mu zingwe zowala zochepa, ulusi wa chingwe umatha kusungunuka kapena chodzaza sichidzakhala chokwanira, zomwe zimakhudza momwe chingwecho chimagwirira ntchito kuti chisanyowe.
