Carbon Fiber Felt

Muaj peb yam tseem ceeb ntawm cov pa roj carbon fiber ntau, uas yog polyacrylonitrile raws cov pa roj carbon zoo, nplaum raws li cov pa roj carbon monoxide, thiab asphalt raws li cov pa roj carbon monoxide. Ntawm lawv, polyacrylonitrile raws li carbon xav tau dav siv, thiab qhov peb feem ntau hu ua carbon fiber ntau yog polyacrylonitrile raws li cov pa roj carbon zoo. Polyacrylonitrile raws li cov pa roj carbon monoxide kuj tseem tuaj yeem muab faib ua ob hom: polyacrylonitrile raws li acrylic fiber ntau thiab polyacrylonitrile raws li (precursor) carbon xav. Lawv qhov txawv yog nyob rau hauv ib qho yog ua los ntawm acrylic fiber, thiab lwm yam yog ua los ntawm carbon fiber raw cov ntaub ntawv. Cov qub muaj kev ua haujlwm tsis zoo dua li yav tas los, nrog lub zog zoo dua, hnov, greyscale, thiab kev txwv piv rau polyacrylonitrile raws li (raws li lo lo ntxhuav) carbon zoo. Yog tias txoj kev ua haujlwm txawv, cov duab ntawm cov pa roj carbon fiber ntau yuav txawv. Muaj lawv ua los ntawm luv luv txiav carbon fiber, nws ua los ntawm pre oxidized fiber, thiab nws ua los ntawm re oxidizing thiab carbonizing cov tsim carbon xav.

Taking polyacrylonitrile based carbon felt as an example, with an area weight of 500g/m2 and 1000g/m2, longitudinal and transverse strengths (N/mm2) of 0.12, 0.16 and 0.10, 0.12 respectively, fracture elongation of 3%, 4% and 18%, 16% respectively, electrical resistivity (Ω · mm) of 4-6, 3.5-5.5 and 7-9, 6-8 respectively, thermal conductivity of 0.06W/(m · K) (25 ℃), specific surface area of>1.5m2/g, tshauv cov ntsiab lus tsawg dua 0.3%, thiab cov ntsiab lus sulfur tsawg dua 0.03%.

Lub cub hluav taws xob ib leeg tam sim no tsim los ntawm peb lub tuam txhab siv cov ntaub ntawv thermal teb uas tau ua kom huv huv hauv qhov kub thiab txias tshwj xeeb, thiab qhov purity tuaj yeem kho raws li cov neeg siv khoom xav tau. Ntawm lawv, cov pa roj carbon zoo li graphite tau raug txhim kho, nrog rau qhov chaw uas tsis muaj tes, tsis plam slag, siab purity, thiab zoo rwb thaiv tsev. Lub caij no, tom qab peb xyoos, kev sib khi zoo heev graphene carbon nanotube txheej slurry tau ua tiav, uas tuaj yeem tiv taus qhov kub thiab txias ntawm 3200 degree ntev thiab tau siv rau ntau lub lag luam.

Cov pa roj carbon slag yog ib qho yooj yim los poob ntawm qhov chaw ntawm cov graphite zoo tib yam

Cov pa roj carbon slag tsis yooj yim rau poob ntawm lub

nto ntawm graphite xav

Compressive zog 1.05-2.45MPa

Kub tiv taus ≥2000 degree siab

Qhov ceev 0 13-0.18g/cm

 

Viscose raws li cov pa roj carbon fiber ntau yog cov khoom siv high-kub rwb thaiv tsev uas ua los ntawm viscose dag silk ua raw khoom.
Nws muaj cov yam ntxwv dav dav ntawm lwm hom kev xav carbon
Nws tseem muaj cov yam ntxwv ntawm qhov ceev thiab qis thermal conductivity, ua rau nws haum rau kev siv cov ntaub ntawv rwb thaiv tsev thiab cov khoom siv xeb.
Tshwj xeeb tshaj yog tsim rau nruab nrab zaus induction high-temperature sintering furnaces thiab lub sij hawm nrog nruj kev cai rau rwb thaiv tsev kev ua tau zoo, nws kuj yog haum raws li ib tug cua sov khoom siv rau quartz cua sov raj thiab xav rau cov cav tov.
