Ukukhetha i-outerial sheath yentambo ye-fiber optic kuhlanganisa ukucabangela izici ezimbalwa ezihlobene nokusetshenziswa kwentambo, indawo, kanye nezimfuneko zokusebenza.Nakhu okunye okucatshangelwayo okubalulekile okuzokusiza ukuthi ukhethe okubalulekile kwesheath yangaphandle yezintambo ze-fiber optic:
Izimo Zemvelo: Hlola izimo lapho intambo izofakwa khona.Cabangela izici ezifana nebanga lokushisa, ukuchayeka kumswakama, amakhemikhali, ukukhanya kwe-UV, imihuzuko, nezinye izingozi ezingaba khona.
Ukuvikelwa Kwemishini: Thola izinga lokuvikelwa komshini elidingekayo.Uma ikhebuli izofakwa ezindaweni ezimazombezombe noma ezindaweni ezisengozini yokulimala ngokomzimba, uzodinga okokusebenza komgodla okunikeza ukumelana okuphezulu nemihuzuko nomthelela.
Ukumelana Nomlilo Nelangabi:Ezinye izinhlelo zokusebenza, ikakhulukazi lezo ezisezindaweni zezimboni noma ezinobungozi obukhulu, zingadinga amakhebuli anamalangabi angavimbeli umlilo noma angaphandle angangeni ukuze athobele imithetho yezokuphepha.
Ukuvumelana nezimo kanye ne-Bend Radius:Ekufakweni lapho ikhebula ingase idinge ukugoba noma ukugoba, ukukhetha okokusebenza kwe-sheath okunikeza ukuguquguquka ngaphandle kokuphazamisa ukusebenza kwekhebula kubalulekile.
Ukumelana Namakhemikhali:Linganisa ukuthi ikhebula lizochayeka yini kumakhemikhali noma ezintweni ezonakalisayo.Khetha okokusebenza kwe-sheath okungamelana nalezi zinto ukuze ugcine ubuqotho bekhebula.
Ukumelana ne-UV:Uma ikhebula lizochayeka elangeni noma ezimweni zangaphandle, izinto ezimelana ne-UV zizovimbela ukuwohloka ngokuhamba kwesikhathi ngenxa yokuchayeka isikhathi eside emisebeni ye-ultraviolet.
Izindleko zokucatshangelwa:Linganisa izidingo zokusebenza nezinkinga zezindleko.Ezinye izinto ezikhethekile zinganikeza izakhiwo eziphakeme kodwa zize ngezindleko eziphakeme.
Ukuhambisana Namazinga:Qinisekisa ukuthi impahla ekhethiwe ye-sheath ihambisana namazinga emboni kanye nemithethonqubo yokusetshenziswa okuhlosiwe.
Izinto ezijwayelekile ezisetshenziselwa imigodla yangaphandle ezintamboni ze-fiber optic zifaka:Indlela yokukhetha i-fiber optic cable outer sheath material?
I-PVC engu-1
2 PE
3 LSZH
4 AT
5 I-Anti-Rodent
6 I-Anti-Flame
I-PVC
I-PVC isetshenziswa kabanzi kakhulu i-fiber optic cable outer sheath material.Inokusebenza kahle, ukumelana namakhemikhali okuhle kanye nokumelana nesimo sezulu, izindleko eziphansi, ukuvutha okuphansi, futhi ingahlangabezana nezidingo zezikhathi ezijwayelekile.Kodwa-ke, ikhebula le-PVC elicwebezelayo lizokhipha intuthu eminyene lapho lishiswa, elingahambisani nemvelo.
PE
Izinto ze-polyethylene sheath azinaphunga, azinabuthi, zizwakala njengengcina.Inokumelana okuhle kakhulu nokushisa okuphansi (izinga lokushisa eliphansi kakhulu lingafinyelela -100~-70 ° C), ukuzinza okuhle kwamakhemikhali, futhi likwazi ukumelana nama-acid amaningi nama-alkali (ayikwazi ukumelana ne-oxidation) Imvelo ye-asidi).Ayincibiliki kuma-solvents ajwayelekile ekamelweni lokushisa, inokumunca amanzi aphansi kanye nokufakwa kukagesi okuhle kakhulu.
Ngenxa yokuminyana okuphansi, ukungena komoya okuhle, ukwahlukanisa okuhle kakhulu kanye nokumelana ne-UV kwe-PE fibre cable sheath yangaphandle, ivamise ukusetshenziswa ezindaweni ezingaphandle.Ngokusekelwe kubuningi be-PE fibre sheath yangaphandle, kukhona ne-MDPE (middle density) ne-HDPE (high density).
I-LSZH
I-LSZH (intuthu ephansi engu-zero halogen) iwumthombo we-sheath ongabambezeli ilangabi ogcwele izigcwalisi ezingaphili (i-aluminium hydroxide, i-magnesium hydroxide).Ikhebula le-LSZH elakhelwe nge-fiber optic alikwazi nje kuphela ukuthambisa ukuhlangana kwezinto ezivuthayo, kodwa futhi limunca ukushisa okukhiqizwa ukusha, futhi ngesikhathi esifanayo likhiqize umgoqo we-oxygen ongashi.
Intambo ye-fiber optic ye-LSZHinokusebenza okuhle kakhulu kokunqanda amalangabi, intuthu encane lapho kusha, ayikho intuthu emnyama enobuthi, ayikho igesi egqwalayo ephumayo, amandla aqinile aqinile, ukumelana nowoyela nokuthambile, ukumelana kahle kakhulu nomfutho ophezulu, ilungele indawo enezimfuneko zokunqanda amalangabi futhi imelana nezidingo zikagesi.Okubi ukuthi i-LSZH sheath kulula ukuqhekeka.
AT
I-sheath yangaphandle yekhebula le-optical ye-AT impahla ingatholakala ngokungeza izithasiselo ku-PE.Lolu hlobo lomgodla lunokusebenza okuhle kokulwa nokulandela umkhondo, ngakho-ke intambo yokubona evame ukusetshenziswa endaweni yolayini wamandla kagesi aphezulu idinga umgodla wezinto ze-AT.
I-Anti-Rodent
Okunye okuvamileintambo yokubonaI-sheathing material i-anti-rodent material, esetshenziselwa izintambo ezibonakalayo ezibekwe emhubheni namaphrojekthi angaphansi komhlaba.Umshini uhlukaniswe ukuvikelwa kwamakhemikhali nokuvikelwa ngokomzimba.Phakathi kwazo, ukuvikela ngokomzimba kuyindlela ehlonipheke kakhudlwana, futhi intambo ye-aramid kanye nezinto ezivikelayo zensimbi zingasetshenziswa ukuvimbela ukulunywa kwamagundane.
I-Anti-Flame
Uma ikhebula le-fiber optic lisetshenziswa ezimayini noma kwenye indawo yangaphambili yokuphepha, izici ezinhle zokunqanda ilangabi zekhebula le-fiber optic zibalulekile.Ikhebula le-optical elingabusheki ilangabi liwumsebenzi we-polyethylene ongagayi amalangabi esikhundleni sezinto ezijwayelekile zekhebula le-polyethylene sheath, ukuze ikhebuli yokubona ibe nezakhiwo ezinganqamuki ilangabi.
