Kev Xaiv thiab Sib Piv ntawm Cov Zoo ntawm Optical Cable Hlau Thiab Cov Uas Tsis Yog Hlau

1. Hlau hlau
Yuav kom ntseeg tau tias lub cable tuaj yeem tiv taus qhov nruj axial txaus thaum tso thiab siv, lub cable yuav tsum muaj cov khoom uas tuaj yeem dais qhov hnyav, hlau, tsis yog hlau, hauv kev siv cov hlau muaj zog siab ua ib feem txhawb zog, yog li ntawd lub cable muaj kev tiv thaiv sab zoo heev, kev cuam tshuam tsis kam, hlau kuj siv rau lub cable ntawm lub plhaub sab hauv thiab lub plhaub sab nraud rau kev ua tsov rog. Raws li nws cov ntsiab lus carbon tuaj yeem faib ua cov hlau carbon siab thiab cov hlau carbon qis.
(1) Cov hlau carbon siab
Cov hlau hlau uas muaj carbon ntau yuav tsum ua tau raws li cov kev cai ntawm GB699 cov hlau carbon zoo, cov ntsiab lus ntawm sulfur thiab phosphorus yog li 0.03%, raws li kev kho qhov chaw sib txawv tuaj yeem muab faib ua cov hlau galvanized thiab cov hlau phosphating. Cov hlau galvanized xav kom cov txheej zinc sib xws, du, thiab ruaj khov, qhov chaw ntawm cov hlau hlau yuav tsum huv, tsis muaj roj, tsis muaj dej, tsis muaj xim; Cov txheej phosphating ntawm cov hlau phosphating yuav tsum sib xws thiab ci, thiab qhov chaw ntawm cov hlau yuav tsum tsis muaj roj, dej, xeb thiab mob. Vim tias qhov ntau ntawm hydrogen evolution yog me me, daim ntawv thov ntawm cov hlau phosphating yog ntau dua tam sim no.
(2) Cov hlau tsis muaj carbon tsawg
Feem ntau, cov hlau carbon tsawg yog siv rau cov xov hlau armored, qhov saum npoo ntawm cov hlau hlau yuav tsum tau plated nrog ib txheej zinc sib xws thiab txuas ntxiv mus, cov txheej zinc yuav tsum tsis muaj kab nrib pleb, cim, tom qab kev sim winding, yuav tsum tsis muaj cov ntiv tes liab qab tuaj yeem tshem tawm qhov tawg, lamination thiab poob tawm.

2. Cov hlau hlua
Nrog rau kev txhim kho ntawm cov cable mus rau tus lej loj ntawm cov tub ntxhais, qhov hnyav ntawm cov cable nce ntxiv, thiab qhov kev nruj uas cov khoom txhawb nqa yuav tsum tau dais kuj nce ntxiv. Txhawm rau txhim kho lub peev xwm ntawm cov cable kho qhov muag kom dais lub nra hnyav thiab tiv taus qhov kev ntxhov siab axial uas yuav tshwm sim hauv kev tso thiab daim ntawv thov ntawm cov cable kho qhov muag, cov hlau strand ua qhov txhawb nqa ntawm cov cable kho qhov muag yog qhov tsim nyog tshaj plaws, thiab muaj qee qhov kev ywj pheej. Cov hlau strand yog ua los ntawm ntau cov hlau hlau twisting, raws li cov qauv seem tuaj yeem faib ua 1 × 3,1 × 7,1 × 19 peb hom. Cov khoom txhawb nqa cable feem ntau siv 1 × 7 hlau strand, cov hlau strand raws li lub zog tensile nominal yog muab faib ua: 175, 1270, 1370, 1470 thiab 1570MPa tsib qib, qhov elastic modulus ntawm cov hlau strand yuav tsum ntau dua 180GPa. Cov hlau siv rau cov hlua hlau yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm GB699 "Cov Kev Cai rau cov qauv hlau carbon zoo", thiab qhov chaw ntawm cov hlau galvanized siv rau cov hlua hlau yuav tsum tau plated nrog ib txheej zinc sib xws thiab txuas ntxiv mus, thiab yuav tsum tsis muaj cov pob, tawg thiab qhov chaw tsis muaj zinc plating. Lub cheeb tsam thiab qhov deb ntawm cov hlua hlau yog sib xws, thiab yuav tsum tsis txhob xoob tom qab txiav, thiab cov hlau ntawm cov hlua hlau yuav tsum tau sib xyaw ua ke, tsis muaj kev sib tshuam, tawg thiab khoov.

3.FRP
FRP yog lub npe luv ntawm tsab ntawv thawj zaug ntawm cov yas fiber reinforced Askiv, uas yog cov khoom siv tsis yog hlau nrog lub ntsej muag du thiab lub cheeb sab nraud sib xws tau los ntawm kev txheej ntawm ntau txoj hlua iav fiber nrog lub teeb kho resin, thiab ua lub luag haujlwm txhawb nqa hauv optical cable. Vim tias FRP yog cov khoom siv tsis yog hlau, nws muaj cov txiaj ntsig zoo li nram no piv rau cov hlau txhawb nqa: (1) Cov khoom siv tsis yog hlau tsis rhiab rau hluav taws xob poob siab, thiab optical cable yog qhov tsim nyog rau thaj chaw xob laim; (2) FRP tsis tsim cov tshuaj tiv thaiv electrochemical nrog dej noo, tsis tsim cov pa phem thiab lwm yam khoom, thiab yog qhov tsim nyog rau thaj chaw nag, kub thiab noo noo; (3) tsis tsim cov hluav taws xob induction, tuaj yeem teeb tsa ntawm cov kab hluav taws xob siab; (4) FRP muaj cov yam ntxwv ntawm qhov hnyav sib dua, uas tuaj yeem txo qhov hnyav ntawm cable. Qhov chaw FRP yuav tsum du, qhov tsis sib npaug yuav tsum me me, lub cheeb yuav tsum sib xws, thiab yuav tsum tsis muaj qhov sib koom ua ke hauv qhov ntev ntawm lub disc.

4. Aramid
Aramid (polyp-benzoyl amide fiber) yog ib hom fiber tshwj xeeb uas muaj zog thiab modulus siab. Nws yog ua los ntawm p-aminobenzoic acid ua monomer, nyob rau hauv qhov muaj catalyst, nyob rau hauv NMP-LiCl system, los ntawm kev daws teeb meem condensation polymerization, thiab tom qab ntawd los ntawm kev sib hloov ntub thiab kev kho cua sov siab. Tam sim no, cov khoom siv feem ntau yog cov qauv khoom KEVLAR49 tsim los ntawm DuPont hauv Tebchaws Meskas thiab cov qauv khoom Twaron tsim los ntawm Akzonobel hauv Netherlands. Vim nws qhov kev tiv taus kub siab zoo heev thiab kev tiv taus thermal oxidation, nws yog siv rau hauv kev tsim cov khoom siv hluav taws xob optical cable txhawb nqa tag nrho-nruab nrab (ADSS).

5. Cov xov paj iav fiber
Cov xov iav fiber yog cov khoom siv uas tsis yog hlau uas feem ntau siv rau hauv kev txhawb nqa cable optical, uas yog ua los ntawm ntau txoj hlua iav fiber. Nws muaj kev rwb thaiv tsev zoo heev thiab tiv taus corrosion, nrog rau lub zog tensile siab thiab qis ductility, ua rau nws zoo tagnrho rau kev txhawb nqa tsis yog hlau hauv cov cable optical. Piv rau cov khoom siv hlau, cov xov iav fiber sib dua thiab tsis tsim hluav taws xob induced, yog li nws yog qhov tshwj xeeb tshaj yog rau cov kab hluav taws xob siab thiab cov ntawv thov cable optical hauv cov chaw ntub dej. Tsis tas li ntawd, cov xov iav fiber qhia tau tias muaj kev tiv thaiv kev hnav zoo thiab tiv taus huab cua hauv kev siv, ua kom ntseeg tau tias lub cable ruaj khov mus sij hawm ntev hauv ntau qhov chaw ib puag ncig.
