Daim ntawv thov ntawm Carbon Black nyob rau hauv Conductive Fiber
Aug 08, 2022
Conductive fibers xa mus rau fibers uas nws resistivity yog tsawg dua 107Ω·cm nyob rau hauv tus txheej txheem lub xeev. High tshwj xeeb kuj conductive fibers yuav siv tau nyob rau hauv anti-static ua hauj lwm khaub ncaws, hnab looj tes, ntaub pua plag, curtains, tsheb sab hauv kho kom zoo nkauj, computer chav studios, tsev kho mob thiab lwm qhov chaw uas yuav tsum tau shielding los ntawm hluav taws xob zoo li qub. Medium tshwj xeeb kuj conductive fibers yog tsuas yog siv nyob rau hauv roj av, petrochemical, thee, yas, roj hmab thiab lwm yam lag luam. Tsawg tshwj xeeb kuj conductive fibers yog tsuas yog siv nyob rau hauv xov tooj cua, TV, electronics, precision khoom thiab lwm yam teb los tiv thaiv electromagnetic cuam tshuam.
Conductive fibers feem ntau hloov kho los ntawm kev sib xyaw cov organic fibers thiab cov khoom siv hluav taws xob. Txoj kev no yuav siv sij hawm kom zoo dua ntawm qhov yooj yim ntawm formability thiab softness ntawm lub polymer, tsis yog tsuas yog los ntawm txawv compounding txoj kev thiab qib ntawm compounding los kho cov degree ntawm hluav taws xob conductivity ntawm fibers, tab sis kuj los ntawm cov degree ntawm molecular orientation nyob rau hauv lub polymer. Nws anisotropy ntawm hluav taws xob conductivity.
Txoj kev npaj yooj yim ntawm carbon dub conductive fiber
1. Txheej txheej txheej
Conductive fibers tuaj yeem tau txais los ntawm txheej carbon dub hmoov nrog ib daim ntawv khi rau saum npoo ntawm cov fibers thiab tom qab ntawd kho lawv. Cov fibers npaj los ntawm txoj kev no muaj cov khoom siv hluav taws xob zoo, tab sis tsis zoo dyeability thiab durability, qis tawm los thiab tus nqi siab.
2. Composite spinning txoj kev
Siv txoj kev sib tov los yog sib tov, carbon dub yog uniformly dispersed nyob rau hauv lub matrix polymer los ua ib tug conductive tivthaiv, thiab ces compounded thiab spun nrog ib tug uas tsis yog-conductive Cheebtsam (lub ntsiab polymer) los npaj ib tug composite conductive fiber. Lub hauv paus polymer ntawm cov khoom siv hluav taws xob muaj xws li polyamide, polyester, polyethylene, polyethylene glycol thiab lwm yam. Cov khoom uas tsis yog-conductive tuaj yeem yog tib lub polymer, lossis ob lossis ntau dua polymers tuaj yeem xaiv.
Txheej txheem conductive fiber ntau
Carbon dub composite conductive fibers nrog carbon dub (acetylene dub, channel carbon dub, rauv dub, thermal cracking carbon dub, mos carbon dub, thiab lwm yam) raws li conductive Cheebtsam yog cov industrialized conductive fibers. ntau yam loj tshaj plaws. Cov pa roj carbon dub siv rau hauv nws yuav tsum muaj qhov tsis muaj zog thiab tuaj yeem tawg tau zoo hauv matrix polymer (polyamide, polyethylene, polyoxyethylene, fatty acid polyester, thiab lwm yam). Cov ntsiab lus ntawm cov pa roj carbon dub hauv cov khoom siv hluav taws xob yog nyob ntawm matrix polymer thiab hom carbon dub. Feem ntau, thaum cov ntsiab lus ntawm cov pa roj carbon dub nyob nruab nrab ntawm 3 feem pua thiab 40 feem pua, qhov kev sib tw tuaj yeem ua kom ntseeg tau zoo, thiab cov khoom siv ntawm cov fiber ntau yuav tsis txo qis. Raws li cov khoom uas tsis yog-conductive, fiber-forming polymers xws li polyethylene terephthalate, polyamide, polyurethane, thiab polyacrylonitrile tuaj yeem siv. Vim qhov sib ntxiv ntawm carbon dub, cov tsos ntawm cov conductive fiber yog dub. Txhawm rau txo qhov kev txwv ntawm cov tsos dub ntawm daim ntawv thov ntau yam, cov pa roj carbon dub sib xyaw ua ke nrog cov duab sib txawv thiab cov duab sib txawv tuaj yeem tsim thiab tsim.
