Polybutylene terephthalate (PBT) yog ib hom yas engineering uas siv lead ua tau zoo heev. Nws muaj peev xwm ua tau zoo heev, loj me ruaj khov, nto zoo, tiv taus kub zoo heev, tiv taus kev laus thiab tiv taus tshuaj lom neeg, yog li nws muaj ntau yam siv tau. Hauv kev lag luam cable sib txuas lus, nws feem ntau yog siv rau txheej txheej thib ob ntawm cov fibers optical los tiv thaiv thiab thaiv cov fibers optical.
Qhov tseem ceeb ntawm cov khoom siv PBT hauv cov qauv fiber optic cable
Lub raj xoob yog siv ncaj qha los tiv thaiv cov fiber ntau optical, yog li nws qhov kev ua tau zoo yog qhov tseem ceeb heev. Qee cov chaw tsim khoom siv cable optic teev cov ntaub ntawv PBT ua qhov kev yuav khoom ntawm Class A cov ntaub ntawv. Vim tias cov fiber ntau optical yog lub teeb, nyias thiab brittle, xav tau lub raj xoob los sib xyaw cov fiber ntau optical hauv cov qauv cable optical. Raws li cov xwm txheej siv, kev ua tiav, cov khoom siv kho tshuab, cov khoom siv tshuaj lom neeg, cov khoom siv thermal thiab cov khoom siv hydrolysis, cov kev cai hauv qab no tau muab tso rau pem hauv ntej rau PBT cov raj xoob.
High flexural modulus thiab zoo bending tsis kam kom tau raws li kev tiv thaiv mechanical.
Cov coefficient thermal expansion qis thiab kev nqus dej tsawg kom tau raws li qhov hloov pauv kub thiab kev ntseeg siab mus sij hawm ntev ntawm cov fiber optic cable tom qab tso.
Yuav kom yooj yim rau kev sib txuas ua haujlwm, yuav tsum muaj kev tiv thaiv cov kuab tshuaj zoo.
Kev tiv thaiv hydrolysis zoo kom ua tau raws li qhov yuav tsum tau ua haujlwm ntawm cov cables optical.
Cov txheej txheem zoo fluidity, tuaj yeem hloov kho rau kev tsim khoom extrusion ceev ceev, thiab yuav tsum muaj kev ruaj khov zoo.
Kev cia siab ntawm cov ntaub ntawv PBT
Cov chaw tsim khoom siv hluav taws xob optical thoob plaws ntiaj teb feem ntau siv nws ua cov khoom siv txheej txheem thib ob rau cov fibers optical vim nws cov nqi ua tau zoo dua.
Hauv cov txheej txheem ntawm kev tsim khoom thiab kev siv cov khoom siv PBT rau cov xov hluav taws xob, ntau lub tuam txhab Suav tau txhim kho cov txheej txheem tsim khoom thiab ua kom zoo dua cov txheej txheem sim, yog li Tuam Tshoj cov khoom siv fiber ntau theem ob txheej PBT tau maj mam lees paub los ntawm lub ntiaj teb.
Nrog rau kev siv tshuab tsim khoom loj, kev tsim khoom loj, cov khoom zoo heev thiab cov nqi khoom pheej yig, nws tau ua qee yam kev pab rau cov tuam txhab tsim khoom siv hluav taws xob thoob ntiaj teb kom txo cov nqi yuav khoom thiab kev tsim khoom thiab tau txais txiaj ntsig zoo dua.
Yog tias muaj cov chaw tsim khoom hauv kev lag luam cable muaj qhov xav tau, thov hu rau peb kom sib tham ntxiv.
