1. Hlau hlau
Txhawm rau kom ntseeg tau tias lub cable tuaj yeem tiv taus txaus axial nro thaum tso thiab thov, lub cable yuav tsum muaj cov khoom uas tuaj yeem nqa lub nra, hlau, tsis yog hlau, hauv kev siv lub zog siab steel hlau ua ib qho kev txhawb zog, yog li ntawd. lub cable muaj zoo heev sab siab tsis kam, cuam tshuam tsis kam, steel hlau kuj yog siv rau lub cable ntawm lub puab sheath thiab cov txheej sheath rau armor. Raws li nws cov ntsiab lus carbon yuav muab faib ua high carbon steel hlau thiab tsawg carbon steel hlau.
(1) High carbon steel hlau
High carbon steel hlau hlau yuav tsum ua tau raws li cov kev cai ntawm GB699 high-zoo carbon steel, cov ntsiab lus ntawm leej faj thiab phosphorus yog hais txog 0.03%, raws li qhov sib txawv deg kho yuav muab faib ua galvanized steel hlau thiab phosphating steel hlau. Galvanized steel hlau yuav tsum tau zinc txheej kom zoo ib yam, du, ruaj khov, qhov saum npoo ntawm cov hlau hlau yuav tsum huv, tsis muaj roj, tsis muaj dej, tsis muaj stains; Cov phosphating txheej ntawm phosphating hlau yuav tsum zoo ib yam thiab ci, thiab saum npoo ntawm cov hlau yuav tsum tsis txhob muaj roj, dej, xeb me ntsis thiab bruises. Vim tias tus nqi ntawm hydrogen evolution me me, daim ntawv thov ntawm phosphating steel hlau yog ntau dua tam sim no.
(2) Tsawg carbon steel hlau
Tsawg carbon steel hlau feem ntau yog siv rau armored cable, nto ntawm steel hlau yuav tsum tau plated nrog ib tug niaj hnub zinc txheej, zinc txheej yuav tsum tsis txhob muaj cov kab nrib pleb, cov cim, tom qab winding xeem, yuav tsum tsis muaj cov ntiv tes liab qab yuav lwv. qhov tawg, lamination thiab poob tawm.
2. Hlau hlua
Nrog rau txoj kev loj hlob ntawm lub cable mus rau cov tub ntxhais loj, qhov hnyav ntawm lub cable nce, thiab qhov nro uas qhov kev txhawb zog yuav tsum tau dais kuj nce. Txhawm rau txhim kho lub peev xwm ntawm cov kab hluav taws xob kho qhov muag kom dais lub nra thiab tiv thaiv qhov kev ntxhov siab axial uas yuav raug tsim los ntawm kev tso thiab kev siv ntawm cov khoom siv kho qhov muag, cov hlau strand raws li lub zog ntawm cov khoom siv kho qhov muag yog qhov tsim nyog tshaj plaws, thiab muaj ib qho yooj yim. Hlau strand yog ua los ntawm ntau cov hlua steel hlau twisting, raws li cov qauv ntu tuaj yeem muab faib ua 1 × 3,1 × 7,1 × 19 peb hom. Cable reinforcement feem ntau siv 1 × 7 steel strand, steel strand raws li nominal tensile lub zog yog muab faib ua: 175, 1270, 1370, 1470 thiab 1570MPa tsib qib, lub elastic modulus ntawm cov hlau strand yuav tsum siab tshaj 180Gpa. Cov hlau siv rau steel strand yuav tsum ua kom tau raws li qhov yuav tsum tau muaj ntawm GB699 "Tsev Txheej Txheem rau cov qauv zoo carbon steel", thiab qhov saum npoo ntawm galvanized steel hlau siv rau steel strand yuav tsum tau plated nrog ib tug niaj hnub txheej thiab tas li ntawm zinc, thiab muaj yuav tsum tsis muaj pob, tawg thiab qhov chaw tsis muaj zinc plating. Txoj kab uas hla thiab nteg nyob deb ntawm cov hlua hlau yog sib xws, thiab yuav tsum tsis txhob xoob tom qab txiav, thiab cov hlau hlau ntawm cov hlua hlau yuav tsum tau ua tib zoo ua ke, tsis muaj crisscross, puas thiab khoov.
3.FRP
FRP yog cov ntawv luv ntawm thawj tsab ntawv ntawm cov lus Askiv fiber ntau reinforced yas, uas yog cov khoom siv tsis yog xim hlau nrog lub ntsej muag du thiab cov kab nruab nrab sab nraud tau los ntawm txheej txheej ntawm ntau cov iav fiber ntau nrog lub teeb curing resin, thiab plays lub zog ntxiv. lub luag haujlwm hauv optical cable. Txij li thaum FRP yog cov khoom siv tsis yog xim hlau, nws muaj qhov zoo hauv qab no piv nrog cov khoom siv hlau: (1) Cov ntaub ntawv tsis yog xim hlau tsis rhiab rau hluav taws xob poob siab, thiab kho qhov muag cable yog tsim rau cov chaw taws teeb; (2) FRP tsis tsim cov tshuaj tiv thaiv electrochemical nrog cov dej noo, tsis tsim cov pa phem thiab lwm yam khoom, thiab tsim nyog rau cov nag, kub thiab huab cua ib puag ncig; (3) tsis tsim induction tam sim no, tuaj yeem teeb tsa ntawm cov kab hluav taws xob siab; (4) FRP muaj cov yam ntxwv ntawm lub teeb yuag, uas tuaj yeem txo qhov hnyav ntawm cable. FRP nto yuav tsum du, qhov tsis yog-roundness yuav tsum me me, txoj kab uas hla yuav tsum yog uniform, thiab yuav tsum tsis txhob muaj kev sib koom ua ke nyob rau hauv tus qauv disc ntev.
4. Aramid
Aramid (polyp-benzoyl amide fiber) yog ib hom fiber ntau tshwj xeeb uas muaj zog thiab siab modulus. Nws yog tsim los ntawm p-aminobenzoic acid li monomer, nyob rau hauv lub xub ntiag ntawm catalyst, nyob rau hauv lub NMP-LiCl system, los ntawm kev daws condensation polymerization, thiab ces los ntawm ntub spinning thiab siab tension tshav kub kho. Tam sim no, cov khoom siv feem ntau yog cov qauv khoom siv KEVLAR49 tsim los ntawm DuPont hauv Tebchaws Meskas thiab cov khoom qauv Twaron tsim los ntawm Akzonobel hauv Netherlands. Vim nws qhov kub thiab txias tsis kam thiab thermal oxidation tsis kam, nws yog siv rau hauv kev tsim khoom ntawm txhua qhov nruab nrab tus kheej txhawb nqa (ADSS) kho qhov muag cable.
5. Cov iav fiber ntau
Cov iav fiber ntau yog cov khoom siv tsis yog xim hlau uas feem ntau siv rau hauv cov khoom siv kho qhov muag, uas yog ua los ntawm ntau cov iav fiber ntau. Nws muaj cov rwb thaiv tsev zoo heev thiab kev tiv thaiv corrosion, nrog rau lub zog tensile siab thiab tsis tshua muaj ductility, ua rau nws zoo tagnrho rau cov khoom siv tsis yog xim hlau hauv cov khoom siv kho qhov muag. Piv nrog rau cov ntaub ntawv hlau, iav fiber ntau yog sib dua thiab tsis tsim kom muaj kev cuam tshuam tam sim no, yog li nws yog qhov tshwj xeeb tshaj yog tsim rau cov kab hluav taws xob siab thiab cov khoom siv kho qhov muag hauv qhov chaw ntub dej. Tsis tas li ntawd, cov iav fiber ntau cov xov paj qhia tau hais tias hnav tsis kam thiab huab cua tsis kam siv, ua kom muaj kev ruaj ntseg ntev ntawm cov cable hauv ntau qhov chaw.
