Cov txheej txheem ntau lawm ntawm carbon fiber

Txoj kev ntawm niaj hnub carbon fiber industrialization yog cov txheej txheem ua ntej fiber ntau carbonization, thiab cov ntsiab lus thiab cov ntsiab lus carbon ntawm peb cov ntaub ntawv raw siv tau qhia hauv lub rooj.
Lub npe ntawm cov khoom siv raw siv rau kev tsim cov roj carbon fiber Cov tshuaj muaj pes tsawg leeg Cov ntsiab lus carbon /% Carbon fiber ntau tawm los /% Viscose fiber (C6H10O5) n4521-35 Polyacrylonitrile fiber (C3H3N) n6840-55 Asphalt fiber C, H{{7 }}
Cov txheej txheem ntawm kev tsim cov pa roj carbon fibers siv peb hom raw fibers suav nrog kev kho kom ruaj khov (hauv huab cua ntawm 200-400 degree , lossis tshuaj kho mob nrog cov nplaim hluav taws kub nyhiab), carbonization (hauv nitrogen ntawm 400-1400 degree), thiab graphitization (siab tshaj 1800 degree hauv argon cua). Txhawm rau txhim kho qhov kev ua tau zoo ntawm cov pa roj carbon fiber ntau thiab cov khoom sib xyaw ua ke, kev kho deg, sizing, ziab thiab lwm yam txheej txheem yuav tsum tau ua.
Lwm txoj hauv kev rau kev tsim cov roj carbon fibers yog cov roj theem kev loj hlob. Los ntawm reacting ib tug sib tov ntawm methane thiab hydrogen nyob rau hauv lub xub ntiag ntawm ib tug catalyst ntawm ib tug kub ntawm 1000 degree, discontinuous luv luv txiav carbon fibers yuav ua tau, nrog ib tug ntev ntev ntawm txog 50cm. Nws cov qauv yog txawv ntawm polyacrylonitrile raws li asphalt raws li carbon fibers, uas yog nquag mus rau graphitization, zoo mechanical zog, siab conductivity, thiab yooj yim rau tsim interlayer tebchaw.
