Carbon fiber muaj kev
Taw qhia
Cov pa roj carbon thiab Graphite muaj lub siab mos mos ua kom lub siab hloov pauv lub teeb txuag lub ntsej muag ib txwm siv hauv lub tshuab nqus tsev thiab tiv thaiv ib puag ncig huab cua txog li 5432 ℉ (3000 ℃). High purity xav kub-kho kom 4712 ℉ (2600 ℃) thiab Halogen Purification muaj rau cov kev cai txiav txim siab ntau lawm. Tsis tas li ntawd, cov khoom siv tuaj yeem siv rau hauv oxidizing kub txog 752 ℉ (400 ℃).
Daim ntawv ntawm kev ua kom cov pa roj carbon fiber yog feem ntau yog kev xav, ntaub, filaments, nrog cov zaub fiber (viscose fiber) lossis lwm cov organic polymer ua cov ntaub ntawv raw, thawj tsim thiab tom qab ntawd ua kom carbonized ua kom zoo.Qhov lub ntsiab yog cov pa roj carbon. Cov atoms carbon muaj nyob rau hauv daim ntawv ntawm cov stacking random ntawm graphite zoo li microcrystals hauv tshuab txais carbon fiber. Kev xaj ntawm qhov chaw peb seem tsis zoo.
Lwm tus yam ntxwv yog tias nws muaj qhov chaw loj, thiab qhov ntau ntawm micropores tau qhib rau ntawm cov nqaij fiber. Hauv cov txheej txheem ntawm adsorption thiab tsim nyog, qhov molecular adsorption kab yog luv, thiab cov adsorbent tuaj yeem ncaj qha nkag mus rau cov micropores.Qhov no muab cov xwm txheej rau cov adsorption ceev ntawm carbon fiber ntau thiab siv cov micropores zoo.
Qhov tshwj xeeb thaj tsam ntawm cov roj carbon fiber carbon ua kom loj, cov pores zoo tsim, cov adsorption kev ua tau zoo, qhov desorption nrawm yog nrawm, tuaj yeem siv dua thiab lwm yam.
Dab tsi yog Qhov txawv ntawm Pan & Rayon Felts?
Polyacrylonitrile, tseem hu ua PAN, yog tsim tawm nrog cov taub loj dua cov kab ua rau ua rau thaj chaw qis dua thiab zoo dua oxidation tsis kam. Cov khoom yoog raws yooj yim yog stiffer thiab mos muag rau qhov kov kov piv rau Rayon. Kev ntsuas cua sov ntawm Rayon yog qis dua PAN ntawm qhov kub siab tshaj 3272 ℉ (1800 ℃).
Rau cov ntawv thov kho cua sov, peb lub chaw ua haujlwm tau pom zoo PAN carbon xav tau vim yog cov khoom siv tau yooj yim thiab txo tus nqi. Yog tias koj ua haujlwm kub tshaj 3272 ℉ (1800 ℃), thov siv Rayon.
NYIAJ POOB HAUJLWM
Yooj yim rau kev txiav thiab txhim kho.
Tsawg tsawg ntom ntom thiab thermal loj.
Siab ua hauj thermal.
Tsawg cov ntoo tshauv thiab cov ntsiab lus leej faj.
Tsis muaj outgassing.
Thov
(1) kuab tshuaj rov qab: benzene, ketone, ester, roj tuaj yeem rov qab adsorption.
(2) cua ntxuav: tuaj yeem nqus thiab lim cov huab cua hauv cov ntxhiab, tsw ntxhiab ntawm lub cev, haus luam yeeb, roj, O3, SO2, TSIS MUAJ.
(3) dej ntxuav: tuaj yeem tshem cov hlau ions hnyav hauv dej, carcinogenic tshuaj, tsw, pwm, kab mob thiab decolorization; Nws tuaj yeem siv rau kev kho cov kais dej, zaub mov kev lag luam dej thiab dej huv.
(4) ib puag ncig kev tsim hluav taws xob: kev tsim cov roj pov tseg thiab kev lim dej;
(5) lub tshuab ua pa, khaub ncaws tiv thaiv, luam tawm lim, thiab lwm yam;
6 cov khoom siv hlau muaj nuj nqis lossis rov ua kom rov qab zoo dua qub, adsorption ntawm cov khoom siv hluav taws xob, kuj tuaj yeem raug siv los ua cov kab hluav taws xob hauv cov roj av, cov roj chromatography ruaj ruaj ntu;
Tshuaj rau hauv pob, mob khaub thuas tiv thaiv kab mob, mob raum, thiab lwm yam;
E. Kev siv hluav taws xob thiab kev siv hluav taws xob, xws li lub peev xwm muaj peev xwm loj, lub roj teeb cia, thiab lwm yam.;
Cov khoom kub siab thiab rwb thaiv tsev.
Kev ua kom cov pa roj carbon fiber ntau raws li cov khoom siv tuaj yeem faib ua viscose, polyacrylonitrile ob series, raws li daim ntawv ntawm:
Cov roj carbon fiber ntau ua kom zoo ● cov ntaub carbon fiber
● tshuab txais carbon fiber ● tshuab txais carbon fiber ntau
