Txhawm rau muab kev ua si tag nrho rau cov txiaj ntsig zoo ntawm cov koom haum tshawb fawb tshawb fawb thiab cov lag luam, tsim kom muaj txiaj ntsig kev tsim kho tshiab, thiab txhim kho kev ywj pheej innovation muaj peev xwm thiab kev sib tw ntawm cov lag luam, tom qab ntau qhov kev sib txuas lus thiab kev sib pauv nyob rau theem pib, thaum Lub Rau Hli 1, lub koom haum ntawm Cov ntaub ntawv ntawm Suav Academy ntawm Kev Tshawb Fawb (IMS) hauv Ningbo, Tuam Tshoj, thiab Shandong Kaitai Petrochemicals Company Limited (tom qab no hu ua Kaitai Petrochemicals) tau kos npe rau daim ntawv cog lus koom tes los tsim "PAN-based Carbon Fiber Engineering Technology Center". (tom qab no hu ua "Kaitai Petrochemical") tau kos npe rau daim ntawv cog lus kev koom tes los koom ua ke tsim "PAN-based Carbon Fiber Engineering thiab Technology Center", uas tau mob siab rau kev tsim kho tshiab thiab kev txhim kho ntawm qhuav polyacrylonitrile (PAN)-based carbon fiber technology.
Tam sim no, cov txheej txheem spinning ntau rau kev ua tau zoo fibers feem ntau muab faib ua ob pawg: yaj spinning thiab tov spinning, uas cov tshuaj spinning yuav muab faib ua qhuav tov spinning (qhuav txoj kev) thiab ntub dej spinning (xws li ntub spinning thiab qhuav. tshuaj tsuag ntub spinning). Qhuav spinning yog PAN spinning kua los ntawm lub metering twj tso kua mis thiab spinneret tsuag extrusion mus rau hauv cov roj ntws ntawm lub spinning lub tog raj kheej (lub tog raj kheej qhuav), cov kuab tshuaj volatilization thiab solidification rau fiber.
Schematic daim duab ntawm qhuav spinning
Kev lig kev cai, cov khoom siv spinning qhuav thiab cov txheej txheem tsis ua haujlwm yog qhov nyuaj, thaum lub spinning tus nqi yog ceev thiab tus nqi sib tw yog siab, uas ua rau nws nyuaj rau spin PAN filaments haum rau carbon fibers. Lub hom phiaj ntawm cov teeb meem kev cuam tshuam, Kaitai Petrochemical Company tau ua ntau txoj haujlwm tshawb fawb, tawg los ntawm lub fwj ntawm qhuav PAN filament ntau lawm tshuab rau kev ua tau zoo carbon fiber ntau, tsim ib tug series ntawm txawv specifications rau carbon fiber ntau ntawm qhuav PAN filaments. , thiab dhau los ntawm cov txheej txheem ua ntej oxidation, carbonization, kom tau txais kev npaj ntawm kev ua tau zoo ntawm PAN-raws li carbon fiber qhuav.
Raws li lub hom phiaj thiab cov dej num ntawm "PAN-based Carbon Fiber Engineering thiab Technology Center" ua ke tsim los ntawm ob tog, pab pawg carbon fiber thiab cov ntaub ntawv sib xyaw ntawm NAMI yuav siv nws cov pa roj carbon fiber ntau lub platform los ua kom tiav kev ntsuas kev ua tau zoo. ntawm qhuav PAN filaments uas tsim los ntawm Kaitai Petrochemicals, tsom rau lub physicochemical qauv ntawm qhuav PAN filaments, evolution ntawm cov qauv nyob rau hauv tus txheej txheem ntawm oxidative carbonization, raws li zoo raws li qhuav PAN-raws li carbon fibers. Nws tsom rau cov qauv physicochemical ntawm qhuav PAN filaments, cov txheej txheem evolution thaum lub sij hawm oxygen carbonization, thiab qhuav PAN-raws li carbon fiber prepreg molding txheej txheem, thiab lwm yam. Nyob rau tib lub sij hawm, nws muab kev cob qhia thiab optimization daws rau qhuav PAN filament cog. ntawm Kaitai Petrochemical.
Piv nrog rau cov txheej txheem ntub dej, cov pa roj carbon monoxide qhuav muaj cov qauv sib txawv tshwj xeeb (cov duab saum toj no qhia tau hais tias qhov sib txawv ntawm cov pa roj carbon fiber ntau ua rau ntawm cov pa roj carbon fiber ntau ntawm Ningbo Institute of Materials, siv Kaitai Petrochemical's qhuav PAN filament li. raw khoom).
Hais txog Shandong Kaitai Petrochemical Company
Shandong Kaitai Petrochemical Company yog tam sim no tsuas yog lub tuam txhab koom nrog hauv kev tsim cov khoom lag luam qhuav PAN-raws li carbon fiber series cov khoom lag luam hauv Suav teb, thiab tau cog lus ntev rau kev tshawb fawb thiab kev tsim kho thiab kev siv cov khoom siv roj carbon fiber ntau nrog cov khoom tshwj xeeb thiab zoo heev. kev ua tau zoo, thiab tau paub txog kev lag luam, high-end, sib txawv thiab kev tsim kho ntawm qhuav PAN-raws li carbon fibers. Lub tuam txhab cov haujlwm tseem ceeb hauv kev lag luam: carbon fiber filament thiab series ntawm cov khoom R & D thiab kev tsim khoom, kev ua haujlwm fiber ntau R & D thiab kev tsim khoom, kev ua haujlwm siab fiber ntau thiab cov ntaub ntawv sib xyaw R & D thiab kev tsim khoom.
Los ntawm kev sib pauv, kev sib tham thiab kev kwv yees nrog ntau lub tsev kawm qib siab, cov chaw tshawb fawb tshawb fawb thiab cov tuam txhab kev lag luam hauv kev tshawb fawb thiab kev tsim cov khoom tshiab PAN-raws li kev lag luam thiab kev cia siab rau kev lag luam, lub tuam txhab tau txiav txim siab txog kev tshawb fawb thiab kev tsim kho thiab kev tsim kho kev lag luam ntawm cov pa roj carbon fiber ntau. series cov khoom lag luam, thiab ua tiav kev tshawb fawb thiab kev tsim cov txheej txheem kev tsim khoom thiab cov khoom siv rau cov khoom siv qhuav PAN filament. 2022, "qhuav spinning ntawm high-performance PAN-raws li carbon fiber filaments rau industrialization" tau teev raws li cov cuab yeej tseem ceeb thiab cov cuab yeej tshawb fawb thiab kev loj hlob ntawm qhuav spinning ntawm high-performance PAN-raws li carbon fiber filaments. Cov thev naus laus zis tseem ceeb thiab cov cuab yeej tshawb fawb thiab kev txhim kho" tau teev tseg raws li Zibo tseem ceeb R & D txoj haujlwm (sab nraum lub nroog tsev kawm kev koom ua ke hauv nroog), hauv lub Peb Hlis ntawm tib lub xyoo, ua tiav thawj txheej ntawm domestic kiloton qhuav spinning PAN-based carbon fiber filament ntau lawm kab, tuaj yeem tsim ntau yam qauv thiab cov yam ntxwv ntawm cov khoom siv fiber ntau filament.
Qhuav-spun PAN-raws li carbon fiber filaments tsim los ntawm Kaitai Petrochemicals
Nyob rau hauv Lub Xya hli ntuj 2022, lub tuam txhab "qhuav spinning ntawm high-kev ua tau zoo PAN-raws li carbon fiber filament industrialization ntawm cov technologies tseem ceeb thiab cov cuab yeej siv kev tshawb fawb thiab kev loj hlob" tau dhau lub Tuam Tshoj Textile Industry Federation ntawm kev tshawb fawb thiab thev naus laus zis ua tiav kev soj ntsuam; nyob rau lub Peb Hlis 2024, thawj cov kab ntau lawm tom qab nthuav dav ntawm kev hloov pauv ntawm thawj txheej ntawm 1,000-ton qhuav spinning ntawm PAN-raws li carbon fiber filament ntau lawm kab nrog ib tug me me cab. kab ntau lawm. Lub tuam txhab tau tsim ntau tshaj 20 lub teb chaws patented technologies nyob rau hauv lub teb ntawm qhuav spinning PAN-raws li carbon fiber thiab nws raw cov ntaub ntawv.
