Ukukhetha imathiriyeli ye-sheath yangaphandle yentambo ye-fiber optic kubandakanya ukuqwalasela izinto ezininzi ezinxulumene nesicelo sentambo, okusingqongileyo, kunye neemfuno zokusebenza.Nantsi eminye imiba ephambili yokukunceda ukhethe imathiriyeli efanelekileyo yesheath yangaphandle yeentambo zefiber optic:
Iimeko zokusingqongileyo: Vavanya iimeko apho intambo iya kufakwa khona.Qwalasela izinto ezinjengoluhlu lobushushu, ukuba sesichengeni kukufuma, imichiza, ukukhanya kweUV, ukugqabhuka, kunye nezinye iingozi ezinokubakho.
Ukukhuselwa komatshini: Ukumisela inqanaba lokhuseleko lomatshini olufunekayo.Ukuba intambo iya kufakwa kwiindawo ezinqabileyo okanye iindawo ezithanda ukonakala ngokwasemzimbeni, uya kufuna i-sheath material enika ukuchasana okuphezulu kwi-abrasion kunye nefuthe.
Ukumelana noMlilo kunye nedangatye:Ezinye izicelo, ngakumbi ezo zikwiimeko zemizi-mveliso okanye ezinomngcipheko omkhulu, zinokufuna iintambo ezineeshethi ezingatshiyo okanye ezinokumelana nomlilo ukuze zithobele imigaqo yokhuseleko.
Ukuguquguquka kunye nokuGobela iRadiyosi:Ufakelo apho intambo inokufuna ukugoba okanye ukugoba, ukukhetha i-sheath material enikezela ukuguquguquka ngaphandle kokuphazamisa ukusebenza kwentambo kubalulekile.
Ukumelana neMichiza:Vavanya ukuba ingaba intambo iya kuba sesichengeni kwiikhemikhali okanye kwizinto ezonakalisayo.Khetha imathiriyeli ye-sheath enokumelana nezi zinto ukugcina ingqibelelo yentambo.
Ukumelana neUV:Ukuba intambo iya kuboniswa kukukhanya kwelanga okanye iimeko zangaphandle, izinto ezichasene ne-UV ziya kuthintela ukuthotywa kwexesha ngenxa yokuvezwa ixesha elide kwimitha ye-ultraviolet.
Ukuqwalaselwa kweendleko:Linganisa iimfuno zokusebenza kunye nemiqobo yeendleko.Ezinye izixhobo ezikhethekileyo zinokubonelela ngeepropati eziphezulu kodwa ziza ngexabiso eliphezulu.
Ukuthotyelwa kunye neMigangatho:Qinisekisa ukuba imathiriyeli ye-sheath ekhethiweyo ihambelana nemigangatho yoshishino kunye nemimiselo yesicelo esicetywayo.
Izixhobo eziqhelekileyo ezisetyenziselwa i-sheaths zangaphandle kwiintambo zefayibha optic ziquka:Unokukhetha Njani imathiriyeli ye-fiber optic cable?
I-PVC eyi-1
2 PE
3 LSZH
4 AT
5 I-Anti-mpuku
6 Anti-idangatye
I-PVC
I-PVC yeyona nto isetyenziswa kakhulu kwi-fiber optic cable yangaphandle.Inokusebenza kakuhle, ukuchasana kakuhle kweekhemikhali kunye nokumelana nemozulu, ixabiso eliphantsi, ukutsha okuphantsi, kwaye inokuhlangabezana neemfuno zezihlandlo eziqhelekileyo.Nangona kunjalo, intambo ye-PVC ene-sheathed optical iya kuvelisa umsi oshinyeneyo xa utshisiwe, ongahambelani nokusingqongileyo.
PE
Izinto ze-polyethylene sheath azinavumba, azinatyhefu, zivakalelwa njenge-wax.Inokumelana neqondo lokushisa eliphantsi kakhulu (iqondo lokushisa eliphantsi kakhulu linokufikelela -100 ~ -70 ° C), ukuzinza kakuhle kweekhemikhali, kwaye inokumelana nobuninzi be-acids kunye ne-alkali (engenakuchasana ne-oxidation) Ubume be-asidi).Ayinyibiliki kwi-solvents ngokubanzi kwiqondo lobushushu begumbi, inokufunxeka kwamanzi aphantsi kunye nokufakelwa kombane okugqwesileyo.
Ngenxa yoxinano oluphantsi, ukungena komoya okulungileyo, ukugquma okugqwesileyo kunye nokumelana ne-UV ye-PE fiber cable yangaphandle sheath, ihlala isetyenziswa kwiindawo ezingaphandle.Ngokusekelwe kubuninzi be-PE fiber cable sheath yangaphandle, kukho kwakhona i-MDPE (ubuninzi obuphakathi) kunye ne-HDPE (ubuninzi obuphezulu).
I-LSZH
I-LSZH (umsi ophantsi we-zero halogen) yimpahla ye-sheath-retardant sheath ezaliswe zi-inorganic fillers (i-aluminium hydroxide, i-magnesium hydroxide).Intambo ye-LSZH ene-sheathed fibre optic ayikwazi nje ukungcungcuthekisa ukuxinana kwezinto ezinokutsha, kodwa iphinde ifunxe ubushushu obuveliswa kukutsha, kwaye kwangaxeshanye ivelise umqobo weoksijini ongatshiyo.
Intambo ye-fiber optic ye-LSZHinomsebenzi ogqwesileyo wokunqanda amadangatye, umsi omncinci ngexesha lokutsha, akukho msi umnyama unetyhefu, akukho gesi enomhlwa ibalekayo, ukomelela okuhle kokuzibamba, ukuxhathisa kwe-oyile kunye nokuthamba, ukumelana noxinzelelo oluphezulu olugqwesileyo, ilungele imekobume eneemfuno zokubuyiswa komlilo kunye nokumelana neemfuno zombane.Ukungalungi kukuba i-sheath ye-LSZH kulula ukuyiqhekeza.
AT
I-sheath yangaphandle yentambo ye-optical ye-AT ingafumaneka ngokufaka izongezo kwi-PE.Olu hlobo lwesingxobo lunomsebenzi olungileyo wokuchasana nokulandela umkhondo, ke ngoko intambo yokukhanya edla ngokusetyenziswa kwindawo yombane ophezulu wombane ifuna isheath yezinto ze-AT.
I-Anti-Rodent
Enye eqhelekileyointambo yokukhanyai-sheathing material yi-anti-rodent material, esetyenziselwa iintambo ezibonakalayo ezibekwe kwiitonela kunye neeprojekthi eziphantsi komhlaba.I-mechanism ihlukaniswe ngokukhuselwa kweekhemikhali kunye nokukhuselwa ngokomzimba.Phakathi kwabo, ukhuseleko lomzimba yindlela ehloniphekileyo, kwaye umsonto we-aramid kunye nezixhobo zentsimbi ezixhobileyo zingasetyenziselwa ukuthintela ukulunywa kweempuku.
Anti-Idangatye
Xa intambo ye-fiber optic isetyenziswa emigodini okanye kwenye indawo ekhuselekileyo yokhuseleko, iimpawu ezilungileyo zokulwa nomlilo ze-fiber optic cable zibalulekile.Intambo ye-optical retardant-flame-retardant yi-polyethylene sheath material ebuyisela idangatye endaweni ye-optical cable ye-polyethylene sheath material eqhelekileyo, ukwenzela ukuba intambo ye-optical ibe neempawu zokunqanda ilangatye.
