Ngemva kweminyaka yokuthuthuka, ubuchwepheshe bokukhiqiza izintambo ze-optical sebuvuthwe kakhulu. Ngaphandle kwezici ezaziwayo zomthamo omkhulu wolwazi kanye nokusebenza okuhle kokudlulisa, izintambo ze-optical nazo ziyadingeka ukuze zibe nezinzuzo zobukhulu obuncane nesisindo esincane. Lezi zici zekhebula le-optical zihlobene eduze nokusebenza kwe-fiber optical, ukwakheka kwesakhiwo sekhebula le-optical kanye nenqubo yokukhiqiza, futhi zihlobene eduze nezinto ezihlukahlukene kanye nezakhiwo ezakha ikhebula le-optical.
Ngokungeziwe kuma-optical fibers, izinto zokusetshenziswa eziyinhloko ezintanjeni ze-optical zihlanganisa izigaba ezintathu:
1. Izinto ze-polymer: impahla yeshubhu eqinile, i-PBT loose tube material, i-PE sheath material, i-PVC sheath material, amafutha okugcoba, itheyiphu yokuvimbela amanzi, itheyiphu ye-polyester
2. Izinto eziyinhlanganisela: itheyiphu eyinhlanganisela ye-aluminium-plastiki, itheyiphu eyinhlanganisela yensimbi-yepulasitiki
3. Izinto zensimbi: ucingo lwensimbi
Namuhla sikhuluma ngezici zezinto eziyinhloko zokusetshenziswa kwekhebula le-optical kanye nezinkinga ezivame ukwenzeka, ngethemba lokuba usizo kubakhiqizi bekhebula le-optical.
1. Tight tube material
Iningi lezinto zokuqala eziqinile zamashubhu kwakusetshenziswa inayiloni. Inzuzo ukuthi inamandla athile kanye nokumelana nokugqoka. Okubi ukuthi ukusebenza kwenqubo kumpofu, izinga lokushisa lokucubungula lincane, kunzima ukulawula, futhi izindleko ziphezulu. Njengamanje, kunezinto ezintsha ezisezingeni eliphezulu nezingabizi kakhulu, njenge-PVC eguquliwe, ama-elastomers, njll. Kusukela ekubukeni kokubuka, i-flame retardant kanye ne-halogen-free material iwumkhuba ongenakugwenywa wezinto eziqinile zamashubhu. Abakhiqizi bezintambo ze-Optical badinga ukunaka lokhu.
2. PBT loose tube material
I-PBT isetshenziswa kabanzi ku-loose tube material ye-fiber optical ngenxa yezakhiwo zayo ezinhle kakhulu zemishini kanye nokumelana namakhemikhali. Izakhiwo zayo eziningi zihlobene eduze nesisindo samangqamuzana. Lapho isisindo samangqamuzana sikhulu ngokwanele, amandla aqinile, amandla okuguquguquka, amandla omthelela aphezulu. Ekukhiqizeni nasekusetshenzisweni kwangempela, kufanele kuqashelwe ekulawuleni ukushuba kwenkokhelo ngesikhathi sekhebula.
3. Ukugcwalisa amafutha
I-fiber optical izwela kakhulu ku-OH–. Amanzi nomswakama kuzokwandisa ama-micro-cracks ebusweni be-fiber optical, okuholela ekunciphiseni okukhulu kwamandla e-fiber optical. I-hydrogen ekhiqizwa ukusabela kwamakhemikhali phakathi komswakamo nezinto zensimbi izobangela ukulahleka kwe-hydrogen kufiber optical futhi ithinte ikhwalithi yentambo ye-fiber optical. Ngakho-ke, i-hydrogen evolution iyinkomba ebalulekile yamafutha.
4. I-tape yokuvimbela amanzi
I-tape yokuvimbela amanzi isebenzisa i-adhesive ukuze inamathele i-resin emunca amanzi phakathi kwezingqimba ezimbili zezindwangu ezingezona ezilukiwe. Lapho amanzi engena ngaphakathi kwekhebula le-optical, i-resin emunca amanzi izomunca ngokushesha amanzi futhi yandise, igcwalise izikhala zekhebula le-optical, ngaleyo ndlela ivimbele amanzi ukuthi angagelezi ngobude nangobubanzi kukhebula. Ngaphezu kokumelana okuhle kwamanzi nokuzinza kwamakhemikhali, ukuphakama kokuvuvukala kanye nezinga lokumunca amanzi ngesikhathi seyunithi yizinkomba ezibaluleke kakhulu ze-tape yokuvimbela amanzi.
5. Itheyiphu eyinhlanganisela yepulasitiki yensimbi kanye netheyiphu eyinhlanganisela yepulasitiki ye-aluminium
Itheyiphu eyinhlanganisela yepulasitiki yensimbi kanye netheyiphu eyinhlanganisela yepulasitiki ye-aluminium kukhebula yokubona ngokuvamile kuvame ukugoqa okude okuboshwe ngothayela , futhi kwenza umgodla obanzi oneshevu yangaphandle ye-PE. Amandla ekhasi etheyiphu yensimbi/ucwecwe lwe-aluminium kanye nefilimu yepulasitiki, amandla okuvala ukushisa phakathi kwamateyipu ayinhlanganisela, namandla okubopha phakathi kwetheyiphu eyinhlanganisela kanye ne-PE yangaphandle sheath kunomthelela omkhulu ekusebenzeni okuphelele kwentambo yokubona. Ukuhambisana kwegrisi nakho kubalulekile, futhi ukubukeka kwetheyiphu eyinhlanganisela yensimbi kufanele kube isicaba, kuhlanzeke, kungabi nama-burrs, futhi kungabi nokulimala komshini. Ngaphezu kwalokho, njengoba itheyiphu eyinhlanganisela yepulasitiki yensimbi kufanele isongwe ngobude ngokufa kokulinganisa ngesikhathi sokukhiqiza, ukufana kogqinsi namandla emishini kubaluleke kakhulu kumkhiqizi wekhebula lokukhanya.
