Product Description
Carbon fiber hmoov, tseem hu ua av carbon fiber, yog ib tug cylindrical particle ntawm sib npaug ntev tau los ntawm tshwj xeeb nto kev kho mob, sib tsoo, microscopic qhia, tshuaj ntsuam xyuas, thiab high-temperature ziab ntawm high-strength thiab siab modulus carbon fiber filaments. Nws khaws ntau yam zoo heev ntawm carbon fiber, thiab muaj ib tug me me, ntshiab nto, loj tshwj xeeb nto, thiab yog yooj yim wetted thiab uniformly dispersed los ntawm resin. Nws yog ib tug high-kev ua tau zoo composite muab tub lim. Cov xim ntawm carbon fiber hmoov yog dub grey.
Nws tuaj yeem sib xyaw nrog cov ntaub ntawv xws li cob, yas, hlau, roj hmab, thiab lwm yam kom muaj zog thiab hnav tsis kam ntawm cov khoom. Nws tau dav siv los ua cov khoom siv hluav taws xob zoo rau cov khoom siv hluav taws xob zoo thiab tsis zoo ntawm cov nickel hydrogen thiab nickel cadmium roj teeb, hluav taws xob chips, conductive daim hlau, conductive flooring, electronic machinery, anti-static industries (coatings, floors, paints, inks), anti -static lim cartridges, tiv thaiv lub teb chaws thiab tub rog industries, tsev rwb thaiv tsev, tshuaj lom neeg cov khoom noj ntxhib pom, maus taus mufflers, huab cua pom nyob rau hauv cov xim kom qhuav chav, polytetrafluoroethylene thiab lwm yam teb.
Nta
Cov conductivity thiab thermal conductivity ntawm carbon fiber hmoov nyob deb tshaj cov khoom siv hlau. Nws cov conductivity yog siab li 10 ⁴ S / m, ua rau nws dav siv nyob rau hauv hluav taws xob Cheebtsam, conductive coatings, thiab anti-static cov ntaub ntawv. Nyob rau tib lub sijhawm, thermal conductivity ntawm carbon fiber hmoov yog siab li 1000 W / m · K, uas tuaj yeem txhim kho cov khoom siv hluav taws xob ua kom sov thiab yog qhov kev xaiv zoo tshaj plaws rau cov ntaub ntawv thermal conductivity.
Txawm hais tias cov khoom ntawm carbon fiber ntau yog me me, nws tau txais lub zog siab thiab lub teeb yuag ntawm carbon fiber nws tus kheej. Nws lub zog tensile raug tshaj 4 GPa thiab nws qhov ceev tsuas yog 1.75 g / cm³. Qhov no ua rau cov hmoov carbon fiber ntau los txhim kho lub zog thiab rigidity ntawm cov ntaub ntawv sib xyaw thaum siv los ua tus neeg sawv cev txhawb zog, thaum tuav lub teeb, ua rau nws tsim tshwj xeeb rau cov ntawv thov uas xav tau lub zog siab thiab qhov hnyav.
Cov roj carbon fiber ntau muaj qhov kub thiab txias tsis kam thiab tuaj yeem nyob ruaj khov ntawm qhov kub txog li 3000 ° C yam tsis muaj melting lossis degradation. Tsis tas li ntawd, cov tshuaj inertness ntawm carbon fiber ua rau nws heev corrosion-resistant rau feem ntau acids, bases, thiab organic solvents. Qhov no ua rau cov pa roj carbon fiber ntau pom qhov zoo hauv cov ntawv thov hauv qhov chaw kub thiab corrosive, xws li cov khoom siv ntsuas kub, cov txheej txheem corrosion-resistant, thiab lwm yam.
Cov pa roj carbon fiber ntau dhau qhov kev ntsuas nruj thiab tshuaj xyuas cov txheej txheem, ua rau cov khoom sib xws. Qhov nruab nrab particle txoj kab uas hla yog 5-50 microns, thiab thaj chaw tshwj xeeb tuaj yeem ncav cuag 50 m ² / g. Cov khoom siv tshwj xeeb saum npoo av no tuaj yeem tsim cov qauv sib txawv hauv cov ntaub ntawv sib xyaw, txhim kho qhov cuam tshuam thiab tag nrho cov khoom siv kho tshuab, thaum tseem muaj cov txiaj ntsig zoo hauv conductivity, thermal conduction, adsorption, thiab lwm yam.
Cov pa roj carbon fiber ntau yog siv los txhim kho cov khoom siv ntawm cov khoom sib xyaw, tshwj xeeb tshaj yog nyob rau hauv cov khoom sib xyaw thiab cov khoom siv ceramic. Cov khoom sib xyaw nrog cov hmoov carbon fiber ntxiv tau txhim kho khoov lub zog, compression lub zog, thiab cuam tshuam toughness. Kev sim cov ntaub ntawv qhia tau hais tias thaum cov roj carbon fiber ntau ntxiv yog 5% -10%, lub zog dabtsi yog khoov ntawm cov khoom sib xyaw tuaj yeem nce ntxiv los ntawm 25% -40%, lub zog compressive tuaj yeem nce los ntawm 30 % -50%, thiab nws muaj kev qaug zog zoo dua.
Cov txheej txheem tsim cov pa roj carbon fiber ntau ua tau raws li qhov yuav tsum tau ua ntawm ib puag ncig, thiab cov khoom siv raw siv yog cov khoom siv txuas ntxiv. Yuav tsis muaj cov pa phem lossis cov dej khib nyiab tsim tawm thaum lub sijhawm tsim khoom. Daim ntawv thov ntawm carbon fiber hmoov kuj pab kom ntev lub neej kev pab cuam ntawm cov khoom, txo cov pov tseg los ntawm cov khoom aging los yog kev puas tsuaj, thiab ua tau raws li cov kev cai ntawm niaj hnub kev lag luam rau sustainable kev loj hlob.
