Hauv kev sib txuas lus niaj hnub no, optical cables tau dhau los ua qhov nruab nrab tseem ceeb rau kev xa cov ntaub ntawv. Txhawm rau txhim kho lub neej ntev thiab kev ntseeg siab ntawm cov kab hluav taws xob kho qhov muag thiab tiv thaiv kev ya raws uas tuaj yeem ua rau kev ua haujlwm tsis zoo, kev tsim cov dej thaiv yog qhov tseem ceeb. Tsab ntawv xov xwm no tsom mus rau cov cuab yeej siv dej thaiv dej ntawm kev sib tshooj ntawm cov hlau nplaum hauv cov kab hluav taws xob kho qhov muag, tshawb xyuas nws qhov tseem ceeb, cov teeb meem, thiab cov txheej txheem ua kom zoo.
Cov Lub luag hauj lwm ntawm Hlau daim kab xev thiab Overlapping Joints
Cov hlau tapes feem ntau siv rau hauv cov khoom siv kho qhov muag (xws li, daim kab xev aluminium, steel daim kab xev) feem ntau yog kev tiv thaiv, kev tiv thaiv, thiab dej thaiv txheej. Cov kab xev no feem ntau yog qhwv ntev ib ncig ntawm cov hlua xoob uas muaj cov fibers optical thiab nruj nreem khi nrog cov ntaub qhwv sab nrauv, ua kom muaj kev tiv thaiv zoo. Txhawm rau kom muaj kev ncaj ncees ntawm cov txheej thaiv no, cov kab sib tshooj ntawm cov hlau nplaum yuav tsum raug kaw kom ruaj ntseg. Txawm li cas los xij, cov pob qij txha no suav tias yog cov ntsiab lus tsis muaj zog hauv cov qauv tag nrho. Yog tias tsis ua haujlwm zoo, cov dej noo tuaj yeem nkag mus los ntawm cov pob qij txha, cuam tshuam rau lub sijhawm ntev ntawm kev ruaj ntseg ntawm cable.
Qhov tseem ceeb ntawm kev thaiv dej ntawm cov sib tshooj sib tshooj
Cov dej thaiv kev ua haujlwm ntawm cov pob qij txha sib tshooj ncaj qha cuam tshuam rau cov kab hluav taws xob kho qhov muag cov dej noo thiab dej tsis kam. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv ib puag ncig zoo li hauv av ducts thiab submarine cables, qhov twg cov cables feem ntau raug rau cov dej ntub dej lossis cov dej hauv dej. Yog tias cov dej xau los ntawm cov hlau nplaum sib tshooj, nws tuaj yeem kis tau raws cov cores fiber ntau, ua rau lub teeb liab attenuation, fiber ntau breakage, los yog tag nrho cov system tsis ua hauj lwm. Yog li, kev kho dej thaiv kev ua haujlwm zoo ntawm cov pob qij txha no yog qhov tseem ceeb.
Common Water-Blocking Techniques for Metal Tape Overlaps
1) Txheej nrog Water-Blocking gel
Siv cov dej tshwj xeeb-thaiv cov gel ntawm cov pob qij txha sib tshooj tuaj yeem kaw qhov khoob thiab tiv thaiv kom tsis txhob ya raws. Txoj kev no yog qhov yooj yim thiab ntau yam, haum rau ntau hom optical cables. Txawm li cas los xij, lub thickness thiab uniformity ntawm gel txheej cuam tshuam rau kev ua haujlwm ntawm cov dej thaiv, yuav tsum muaj kev tswj xyuas nruj ntawm cov txheej txheem tsis.
2) Sealing nrog Kub-melt Adhesive daim kab xev
Kub-melt nplaum daim kab xev tuaj yeem siv los kaw cov ntaub nplaum hlau sib tshooj. Cov kab xev yog rhuab nrog lub rhaub, tso cai rau nws kom nruj rau cov hlau nto, uas ua rau muaj kev sib khi zoo heev thaum txhim kho cov khoom siv hluav taws xob cable. Tus yuam sij rau cov txheej txheem no yog nyob rau hauv kev xaiv cov khoom siv nplaum nplaum thiab kev tswj xyuas meej ntawm qhov kub thiab txias.
3) Co-Extruded Water-Blocking Txheej
Thaum lub sij hawm extrusion ntawm cable sheath, cov khoom siv thermoplastic nrog dej thaiv cov khoom yog co-extruded los npog cov hlau daim kab xev overlaps. Cov txheej txheej co-extruded no tsis yog tsuas yog muab cov dej ua haujlwm zoo xwb tab sis kuj tseem txhim kho kev tiv thaiv txhua yam. Txawm hais tias cov txheej txheem no muaj tus nqi siab, nws muaj kev tiv thaiv dej ntev ntev.
4) Seam Vuam rau Overlaps
Cov tswv yim zoo xws li micro laser vuam lossis ultrasonic vuam tuaj yeem siv los vuam cov hlau daim kab xev sib tshooj rau hauv ib qho kev sib koom ua ke, kaw cov qauv. Txoj kev no muab cov nyhuv dej thaiv zoo tshaj plaws tab sis yuav tsum muaj cov khoom siv high-end, ua rau nws tsim nyog rau cov khoom siv kho qhov muag zoo tshaj plaws.
Optimization thiab kev sib tw hauv Dej-txhim thev naus laus zis
1) Xaiv cov khoom thaiv dej
Xaiv cov khoom thaiv dej kom raug yog qhov tseem ceeb rau kev ua haujlwm ntawm cov dej thaiv cov cuab yeej ntawm cov hlau nplaum sib tshooj. Cov ntaub ntawv uas muaj xws li dej-thaiv gels, kub-melt nplaum nplaum, thiab cov ntaub ntawv co-extrusion. Thaum xaiv cov ntaub ntawv no, nws yog ib qho tseem ceeb uas yuav tau xav txog yam xws li kev sib raug zoo nrog cov hlau nplaum, lub zog adhesion, kub tsis kam, thiab kev laus ua haujlwm.
2) Precise Control of Process Parameters
Hauv kev tsim khoom tiag tiag, nws yog qhov tseem ceeb rau kev tswj hwm ntau yam tsis zoo ntawm cov txheej txheem dej thaiv. Piv txwv li, cov thickness ntawm cov dej thaiv cov gel txheej, cov cua kub kub rau cov nplaum nplaum nplaum, thiab cov thickness ntawm co-extruded txheej tuaj yeem cuam tshuam ncaj qha rau qhov kawg dej thaiv kev ua haujlwm. Txhawm rau txhim kho kev ua haujlwm ntawm cov khoom lag luam thiab cov khoom sib xws, cov khoom siv hluav taws xob siv hluav taws xob tau pom zoo rau kev tswj xyuas kom meej.
3) Environmental Adaptability Testing
Cov kab hluav taws xob kho qhov muag tau npaj rau cov xwm txheej sib txawv (piv txwv li, submarine, hauv av, lossis qhov chaw ntub dej) yuav tsum tau ua ntau yam kev ntsuas dej-thaiv kev ua tau zoo, suav nrog kev nrawm nrawm, kev ntsuas ntsev ntsev, thiab kev sim rau hauv av, kom muaj kev ruaj ntseg hauv kev siv tiag tiag.
Xaus
Cov dej thaiv tshuab ntawm kev sib tshooj ntawm cov hlau nplaum hauv cov kab hluav taws xob kho qhov muag yog qhov tseem ceeb hauv kev ua kom ruaj ntseg cable. Raws li kev sib txuas lus thev naus laus zis txuas ntxiv mus ntxiv, daim ntawv thov scenarios rau optical cables tau dhau los ua ntau haiv neeg thiab nyuaj, ua rau muaj kev txwv nruj rau kev ua haujlwm ntawm cov dej thaiv. Nyob rau hauv lub neej yav tom ntej, peb cia siab tias yuav leveraging txoj kev loj hlob ntawm cov ntaub ntawv tshiab thiab advanced technologies los txhim kho cov dej-blocking peev xwm ntawm optical cables, zoo dua raws li kev lag luam xav tau.
