Kugwiritsa ntchito Ultra-Short Carbon Fiber

Monga membala wofunikira pagawo lazophatikiza zapamwamba, ultra-short carbon fiber, yokhala ndi mawonekedwe ake apadera, yadzetsa chidwi chofala m'mafakitale ambiri ndi ukadaulo. Amapereka yankho latsopano lazinthu zogwirira ntchito kwambiri, ndipo kumvetsetsa mozama zamaukadaulo ndi njira zake ndikofunikira kuti pakhale chitukuko cha mafakitale ogwirizana.

Ma electron micrographs a ultrashort carbon fibers

Nthawi zambiri, kutalika kwa ultra-short carbon fibers ndi pakati pa 0.1 - 5mm, ndipo kachulukidwe kake ndi kochepa pa 1.7 - 2g / cm³. Ndi kachulukidwe kakang'ono ka 1.7 - 2.2g/cm³, kulimba kwamphamvu kwa 3000 - 7000MPa komanso modulus ya elasticity ya 200 - 700GPa, zida zabwino kwambiri zamakinazi zimapanga maziko ogwiritsira ntchito ponyamula katundu. Kuphatikiza apo, ili ndi kukana kwabwino kwambiri kwa kutentha kwambiri, ndipo imatha kupirira kutentha kopitilira 2000 ° C mumlengalenga wopanda oxidizing.

Tekinoloje ya Kugwiritsa Ntchito ndi Njira ya Ultra-short Carbon Fiber mu Aerospace Field

M'munda wamlengalenga, ultra-short carbon fiber imagwiritsidwa ntchito makamaka kulimbitsautomonimatrix kompositi. Chinsinsi chaukadaulo ndikupangitsa kuti mpweya wa kaboni ukhale wobalalika mu matrix a utomoni. Mwachitsanzo, kutengera akupanga kupezeka luso akhoza mogwira kuswa chodabwitsa cha mpweya CHIKWANGWANI agglomeration, kuti kupezeka koyenelera ukufika oposa 90%, kuonetsetsa kugwirizana kwa zinthu katundu. Pa nthawi yomweyo, ntchito CHIKWANGWANI pamwamba mankhwala luso, monga ntchitocoupling wothandizirachithandizo, akhoza kupangacarbon fiberndipo mphamvu yolumikizira utomoni idakwera ndi 30% - 50%.

Popanga mapiko a ndege ndi zida zina zomangira, kugwiritsa ntchito njira yopondereza yotentha. Choyamba, ultra-short carbon fiber ndi utomoni wosakanikirana ndi gawo lina lopangidwa ndi prepreg, zosanjikiza mu thanki yotentha yosindikizira. Kenaka amachiritsidwa ndikuwumbidwa pa kutentha kwa 120 - 180 ° C ndi kupanikizika kwa 0.5 - 1.5MPa. Njirayi imatha kutulutsa thovu la mpweya muzinthu zophatikizika kuti zitsimikizire kulimba komanso magwiridwe antchito apamwamba azinthuzo.

Ukadaulo ndi Njira Zogwiritsira Ntchito Ultra-Short Carbon Fiber pamakampani agalimoto

Mukamagwiritsa ntchito ultra-short carbon fiber pazigawo zamagalimoto, cholinga chake ndikuwongolera kugwirizanitsa kwake ndi zinthu zoyambira. Powonjezera ma compatibilizers enieni, kulumikizana kwapakati pakati pa kaboni ulusi ndi zida zoyambira (mwachitsanzo.polypropylene, etc.) zitha kuonjezedwa pafupifupi 40%. Panthawi imodzimodziyo, kuti apititse patsogolo ntchito zake m'madera ovuta kwambiri, teknoloji yopangira fiber orientation design imagwiritsidwa ntchito kusintha kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.

Njira yopangira jakisoni nthawi zambiri imagwiritsidwa ntchito popanga magawo monga ma hood agalimoto. Ma Ultra-short carbon fibers amasakanizidwa ndi tinthu tating'ono tapulasitiki kenaka amabayidwa mu nkhungu chifukwa cha kutentha kwambiri komanso kupanikizika. Kutentha kwa jekeseni nthawi zambiri kumakhala 200 - 280 ℃, kuthamanga kwa jekeseni ndi 50 - 150 MPa. Njirayi imatha kuzindikira kupangidwa mwachangu kwa magawo owoneka bwino, ndipo imatha kuwonetsetsa kugawidwa kofanana kwa ulusi wa kaboni muzinthuzo.

Tekinoloje ndi Njira Yogwiritsira Ntchito Kwambiri Kwambiri Carbon Fiber mu Electronics Field

Pankhani ya kutentha kwamagetsi, kugwiritsa ntchito matenthedwe amtundu wa ultra-short carbon fibers ndikofunikira. Ndi kukhathamiritsa graphitization digiri ya mpweya CHIKWANGWANI, matenthedwe madutsidwe ake akhoza ziwonjezeke kupitirira 1000W/(mK). Pakadali pano, kuwonetsetsa kukhudzana kwake bwino ndi zida zamagetsi, ukadaulo wazitsulo zam'madzi, monga kupaka utoto wa faifi tambala, kumatha kuchepetsa kukana kwa carbon fiber ndi 80%.

Ufa zitsulo ndondomeko angagwiritsidwe ntchito popanga kompyuta CPU heatsinks. The kopitilira muyeso-waufupi mpweya CHIKWANGWANI wothira zitsulo ufa (mwachitsanzo ufa wamkuwa) ndi sintered pansi kutentha ndi kukakamizidwa. Kutentha kwa sintering nthawi zambiri kumakhala 500 - 900 ° C ndipo kupanikizika ndi 20 - 50 MPa. Izi zimathandiza kuti mpweya wa carbon upange njira yabwino yopangira kutentha ndi chitsulo ndikuwongolera kutentha kwa kutentha.

Kuchokera pazamlengalenga kupita kumakampani amagalimoto kupita ku zamagetsi, ndi luso lopitilirabe laukadaulo ndi kukhathamiritsa kwa njira, kopitilira muyesocarbon fiberidzawala m'magawo ambiri, ndikulowetsa mphamvu zamphamvu za sayansi yamakono ndi zamakono ndi chitukuko cha mafakitale.
