Kusankha zinthu zakunja kwa chingwe cha fiber optic kumaphatikizapo kuganizira zinthu zingapo zokhudzana ndi kagwiritsidwe ntchito ka chingwe, chilengedwe, ndi zofunikira pakuchita.Nazi zina zofunika zomwe zingakuthandizeni kusankha zida zoyenera zakunja za zingwe za fiber optic:
Mikhalidwe Yachilengedwe: Yang'anani momwe chingwe chidzakhazikitsidwira.Ganizirani zinthu monga kusiyanasiyana kwa kutentha, kukhudzana ndi chinyezi, mankhwala, kuwala kwa UV, abrasion, ndi zoopsa zina.
Kutetezedwa Kwamakina: Dziwani kuchuluka kwa chitetezo chamakina chofunikira.Ngati chingwecho chidzayikidwa m'malo ovuta kapena madera omwe amatha kuwonongeka, mudzafunika zida za sheath zomwe zimapereka kukana kwakukulu kwa abrasion ndi kukhudzidwa.
Kulimbana ndi Moto ndi Lawi:Ntchito zina, makamaka zomwe zili m'mafakitale kapena malo omwe ali pachiwopsezo chachikulu, angafunike zingwe zokhala ndi zingwe zozimitsa moto kapena zakunja zosagwira moto kuti zigwirizane ndi malamulo achitetezo.
Flexibility ndi Bend Radius:Pakuyika komwe chingwe chingafunikire kupindika kapena kupindika, kusankha chinthu cha sheath chomwe chimapereka kusinthasintha popanda kusokoneza magwiridwe antchito a chingwe ndikofunikira.
Kukaniza Chemical:Onani ngati chingwecho chikhala ndi mankhwala kapena zinthu zowononga.Sankhani chinthu cha sheath chomwe chingakane zinthu izi kuti musunge kukhulupirika kwa chingwe.
Kukaniza kwa UV:Ngati chingwecho chidzayatsidwa ndi kuwala kwa dzuwa kapena kunja, zida zolimbana ndi UV zimalepheretsa kuwonongeka pakapita nthawi chifukwa chakukhala kwanthawi yayitali ndi kuwala kwa ultraviolet.
Kuganizira za Mtengo:Yerekezerani zofunikira zogwirira ntchito ndi zopinga zamtengo.Zida zina zapadera zimatha kupereka katundu wapamwamba koma zimabwera pamtengo wokwera.
Kutsatira ndi Miyezo:Onetsetsani kuti zinthu zosankhidwa za sheath zikugwirizana ndi miyezo yamakampani ndi malamulo omwe akufunidwa.
Zida zomwe zimagwiritsidwa ntchito popanga zingwe zakunja mu zingwe za fiber optic ndi izi: Momwe Mungasankhire chingwe chakunja cha fiber optic?
1 PVC
2 PE
3 LSZH
4 AT
5 Anti-Koswe
6 Anti-flame
Zithunzi za PVC
PVC ndiye chimagwiritsidwa ntchito kwambiri CHIKWANGWANI chamawonedwe chingwe kunja m'chimake zakuthupi.Ili ndi machitidwe abwino, kukana kwamankhwala abwino komanso kukana kwanyengo, mtengo wotsika, kutsika kwamoto, ndipo imatha kukwaniritsa zofunikira zanthawi zonse.Komabe, chingwe chowoneka bwino cha PVC chidzatulutsa utsi wandiweyani ukawotchedwa, zomwe sizogwirizana ndi chilengedwe.
PE
Zipangizo za m'chimake za polyethylene ndizopanda fungo, zopanda poizoni, zimamveka ngati sera.Ili ndi kukana kwambiri kwa kutentha kochepa (kutentha kwambiri kumatha kufika -100 ~ -70 ° C), kukhazikika kwa mankhwala abwino, ndipo kungathe kupirira ma acid ambiri ndi alkalis (osagonjetsedwa ndi okosijeni) Chikhalidwe cha asidi).Ndi insoluble mu zosungunulira ambiri kutentha firiji, ali otsika mayamwidwe madzi ndi kwambiri kutchinjiriza magetsi.
Chifukwa cha kachulukidwe kakang'ono, mpweya wabwino, kutsekemera kwabwino komanso kukana kwa UV kwa PE fiber chingwe chakunja, nthawi zambiri amagwiritsidwa ntchito m'malo akunja.Kutengera kachulukidwe ka chingwe chakunja cha PE, palinso MDPE (kachulukidwe wapakatikati) ndi HDPE (kachulukidwe kwambiri).
Mtengo wa LSZH
LSZH (utsi wochepa zero halogen) ndi m'chimake choletsa moto wodzadza ndi ma inorganic fillers (aluminium hydroxide, magnesium hydroxide).LSZH sheathed CHIKWANGWANI chamawonedwe chingwe osati kuchepetsa ndende ya zinthu zoyaka, komanso kuyamwa kutentha kwaiye chifukwa kuyaka, ndipo nthawi yomweyo kupanga chosayaka chotchinga mpweya.
LSZH CHIKWANGWANI chamawonedwe chingweimakhala ndi ntchito yabwino yoletsa malawi, utsi wochepa ukayaka, palibe utsi wakuda wapoizoni, palibe mpweya wowononga, kulimba kwamphamvu, kukana kwamafuta ndi kufewa, kukana kwamphamvu kwambiri, koyenera chilengedwe chokhala ndi zofunikira zoletsa moto komanso kupirira zofunikira zamagetsi.Choyipa chake ndikuti sheath ya LSZH ndiyosavuta kusweka.
AT
Chophimba chakunja cha chingwe cha kuwala cha AT chakuthupi chikhoza kupezeka powonjezera zowonjezera ku PE.Mtundu woterewu umakhala ndi magwiridwe antchito abwino oletsa kutsatira, chifukwa chake chingwe chowunikira chomwe chimagwiritsidwa ntchito pamagetsi apamwamba kwambiri chimafunikira sheath ya zinthu za AT.
Anti-Koswe
Wina wambakuwala chingwesheathing material ndi zinthu zotsutsana ndi makoswe, zomwe zimagwiritsidwa ntchito pazingwe za kuwala zomwe zimayikidwa mu tunnel ndi ntchito zapansi.Makinawa amagawidwa kukhala chitetezo chamankhwala komanso chitetezo chathupi.Pakati pawo, chitetezo chakuthupi ndi njira yolemekezeka kwambiri, ndipo ulusi wa aramid ndi zida zachitsulo zokhala ndi zida zitha kugwiritsidwa ntchito popewa kuluma makoswe.
Anti-Flame
Chingwe cha fiber optic chikagwiritsidwa ntchito m'migodi kapena malo ena otetezedwa kale, mawonekedwe abwino odana ndi moto a chingwe cha fiber optic ndikofunikira.Chingwe chotchinga moto ndi chotchingira moto cha polyethylene sheath m'malo mwachingwe chowoneka bwino cha polyethylene sheath, kotero kuti chingwe chowunikira chimakhala ndi zinthu zoletsa moto.
