Cov roj carbon fiber
Kev Taw Qhia
Cov ntaub ntawv carbon thiab graphite yog cov khoom siv rwb thaiv tsev uas muaj qhov kub thiab txias thiab mos mos uas feem ntau siv rau hauv qhov chaw nqus tsev thiab chaw tiv thaiv huab cua txog li 5432℉ (3000℃). Cov ntaub ntawv purity siab uas tau kho cua sov txog li 4712℉ (2600℃) thiab Halogen Purification muaj rau cov xaj tsim khoom tshwj xeeb. Tsis tas li ntawd, cov khoom siv no tuaj yeem siv rau hauv qhov kub thiab txias oxidizing txog li 752℉ (400℃).
Cov qauv ntawm cov roj carbon fiber activated feem ntau yog ua los ntawm cov ntaub, cov xov, cov filaments, nrog cov zaub fiber (viscose fiber) lossis lwm cov organic polymer ua cov khoom siv raw, thawj zaug tsim thiab tom qab ntawd carbonized activation. Lub ntsiab lus tseem ceeb yog carbon. Cov pa roj carbon atoms muaj nyob rau hauv daim ntawv ntawm random stacking ntawm graphite-zoo li microcrystals hauv activated carbon fiber. Kev txiav txim ntawm peb-seem qhov chaw tsis zoo.
Lwm yam ntxwv yog tias nws muaj thaj chaw loj, thiab muaj ntau lub qhov me me qhib rau ntawm qhov chaw fiber. Thaum lub sijhawm adsorption thiab desorption, txoj kev adsorption molecular luv luv, thiab cov adsorbent tuaj yeem nkag mus rau hauv cov qhov me me ncaj qha. Qhov no muab cov xwm txheej rau kev adsorption sai ntawm cov roj carbon fiber thiab kev siv cov qhov me me zoo.
Qhov chaw tshwj xeeb ntawm cov fiber activated carbon yog loj, qhov pores tau tsim zoo, qhov kev ua tau zoo adsorption yog siab, qhov ceev desorption yog ceev, tuaj yeem siv dua thiab lwm yam.
Qhov txawv ntawm Pan & Rayon Felts yog dab tsi?
Polyacrylonitrile, tseem hu ua PAN, yog tsim los ntawm cov fibers loj dua uas ua rau thaj chaw qis dua thiab tiv taus oxidation zoo dua. Cov khoom siv yooj ywm yog tawv dua thiab tsis mos dua rau qhov kov piv rau Rayon. Kev ua haujlwm thermal ntawm Rayon qis dua PAN ntawm qhov kub ntau dua 3272 ℉ (1800 ℃).
Rau cov ntawv thov kho cua sov, peb lub chaw ua haujlwm pom zoo kom siv PAN carbon felt vim nws yooj yim tuav cov ntaub ntawv thiab tus nqi qis dua. Yog tias koj ua haujlwm ntawm qhov kub siab dua 3272 ℉ (1800 ℃), thov siv Rayon.
COV TXHOJ NYIAJ
Yooj yim txiav thiab teeb tsa.
Qhov ceev tsawg thiab thermal mass.
Kev ua haujlwm kub siab.
Muaj cov tshauv thiab sulfur tsawg.
Tsis muaj kev tso pa tawm.
Daim Ntawv Thov
(1) kev rov qab los ntawm cov kuab tshuaj: benzene, ketone, ester, roj tuaj yeem rov qab los ntawm kev nqus.
(2) kev ntxuav cua: tuaj yeem nqus thiab lim cov pa hauv cov ntxhiab tsw, ntxhiab tsw ntawm lub cev, pa luam yeeb, roj, O3, SO2, NO.
(3) kev ntxuav dej: tuaj yeem tshem tawm cov hlau hnyav hauv dej, cov tshuaj carcinogenic, tsw ntxhiab, pwm, kab mob thiab decolorization; Nws tuaj yeem siv rau kev kho dej kais, dej lag luam zaub mov thiab dej ntshiab kev lag luam.
(4) kev tsim kho ib puag ncig: kev kho cov pa roj khib nyiab thiab dej phwj tuaj;
(5) cov khoom siv ua pa, cov khaub ncaws tiv thaiv, cov lim luam yeeb, thiab lwm yam.;
6. Kev rho tawm lossis rov qab los ntawm cov hlau muaj nqis, kev nqus cov tshuaj radioactive, kuj tseem siv tau ua tus cab kuj catalyst, roj chromatography theem ruaj khov;
Tshuaj rau ntawm pob khoom, tshuaj tua kab mob sai, raum dag, thiab lwm yam.;
E. Cov ntawv thov hluav taws xob thiab lub zog, xws li cov capacitors muaj peev xwm siab, cov roj teeb cia khoom, thiab lwm yam;
Cov ntaub ntawv kub thiab rwb thaiv tsev.
Cov roj carbon fiber ua raws li cov khoom siv tuaj yeem muab faib ua viscose, polyacrylonitrile ob series, raws li daim ntawv ntawm:
● daim ntaub ua los ntawm cov pa roj carbon fiber ● daim ntaub ua los ntawm cov pa roj carbon fiber
● Cov roj carbon fiber uas ua kom cov pa roj carbon fiber ua haujlwm ● Daim ntawv ua kom cov pa roj carbon fiber ua haujlwm
