Makhalidwe, kugwiritsa ntchito ndi chitukuko cha carbon fiber
1.Makhalidwe ndi katundu wa carbon fiber
Zida za carbon fiber ndi zakuda, zolimba, zamphamvu kwambiri, zolemera zopepuka ndi zida zina zatsopano zokhala ndi zida zabwino zamakina.Mphamvu yokoka yake ndi yochepera 1/4 yachitsulo.Kulimba kwamphamvu kwa zinthu zophatikizika za carbon fiber resin nthawi zambiri kumakhala pamwamba pa 35000MPa, nthawi 7.9 kuposa chitsulo.The tensile modulus of elasticity ili pakati pa 230000MPa ndi 430000MPa.Choncho, mphamvu yeniyeni ya CFRP, ndiko kuti, chiŵerengero cha mphamvu ya zinthu ndi kachulukidwe kake, ndi pamwamba pa 20000MPa / (g / cm3), koma mphamvu yeniyeni ya A3 zitsulo ndi 590MPa / (g / cm3) zotanuka modulus ndi apamwamba kuposa zitsulo.Kukwera kwamphamvu kwachindunji kwa zinthuzo, kumachepetsa kudzilemera kwa gawolo, kukwezera modulus yeniyeni yeniyeni, kukulirakulira kwa gawolo.M'lingaliroli, chiyembekezo chogwiritsa ntchito kwambiri cha carbon fiber mu engineering chikuwonetsedwa.Kuyang'ana zinthu zabwino kwambiri zazinthu zambiri zomwe zikubwera, monga Polymer kompositi galasi fiber chuma, zitsulo zopangidwa ndi zitsulo zopangidwa ndi zitsulo zopangidwa ndi zitsulo zopangidwa ndi zitsulo zopangidwa ndi ceramic, akatswiri ambiri amaneneratu kuti zipangizo zamakono zidzalowa mu nthawi ya kufalikira kwa zinthu kuyambira zaka zachitsulo.
PAN carbon fiber ndi fiberglass zophatikizika:
(1) makina katundu, m'munsi kachulukidwe kuposa zitsulo, kuwala kulemera;high modulus, high rigidity, high mphamvu, mkulu kutopa mphamvu, kwambiri kuvala kukana ndi lubricity;kugwedezeka kwabwino kwa vibration;
(2) Small kutentha kukana, bata, matenthedwe kukulitsa coefficient, wabwino dimensional bata, madutsidwe matenthedwe;kwambiri kutentha kukana mu mpweya inert;
(3) Ndi yamitundu yosiyanasiyana yazinthu zomwe zimakhala ndi madulidwe amagetsi ndi ma electromagnetic wave shielding properties, komanso ma conductivity amagetsi ndi ma electromagnetic wave shielding properties.(4) Ndi yabwino kwambiri pa X-ray transmittance, ndipo kamangidwe koyenera kakhoza kupangidwa molingana ndi cholingacho.
Mu 2007, Japan wamkuluWopereka kaboni fiberToray Co., Ltd. inagwirizana ndi Nissan Motor ndi makampani ena kuti apange zipangizo zamakono pogwiritsa ntchito mpweya wa carbon, zomwe zingachepetse kwambiri kulemera kwa mbali zazikulu za galimoto, monga galimotoyo.Ukadaulo watsopano umachepetsa kulemera kwagalimoto ndi 10% ndikuwongolera kugwiritsa ntchito mafuta ndi 4% mpaka 5%.Kuphatikiza apo, kukana kwamphamvu kumakhala nthawi 1.5 kuposa momwe zimakhalira.Opanga akukonzekera kubweretsa ukadaulo watsopano ku magalimoto amalonda pazaka zitatu.Tekinoloje yatsopanoyi ikulonjeza kuti ifulumizitsa kusintha kwa zida zamagalimoto zapakati pazitsulo potengera malamulo okhwima amafuta kuti achepetse mpweya wowonjezera kutentha padziko lonse lapansi.
2.Kugwiritsa ntchito carbon fiber
Mpweya wa kaboni ndi mawu omwe amatanthauza ulusi wokhala ndi mpweya wopitilira 90%, ndipo amatchulidwa chifukwa cha kuchuluka kwake kwa mpweya.Mpweya wa kaboni uli ndi zinthu zabwino kwambiri za elemental carbon, monga mphamvu yokoka yaing'ono, kukana kutentha, kukana kutenthedwa kwa kutentha, kukana kwa mankhwala ndi ma conductivity, ndi zina zotero. Zimakhala ndi kulowetsedwa kwa fiber komanso makina abwino kwambiri.Makamaka, mphamvu zake zenizeni komanso zotanuka modulus ndizokwera, ndipo zimatha kupirira kutentha kwambiri kwa 2000 pansi pazikhalidwe zodzipatula mpweya.Ndi zofunika mafakitale fiberglass zopangirandipo ndi yoyenera kulimbikitsa zida zophatikizika, zida zotulutsa, ndi zida zotchinjiriza kutentha.Ichi ndi nkhani yatsopano yomwe idapangidwa koyambirira kwa zaka za m'ma 1960 ndipo tsopano yakhala chinthu chatsopano chofunikira kwambiri masiku ano.
Pakati pazinthu zosangalatsa, kugwiritsa ntchito koyamba kwa PAN carbon fiber ndi ndodo yophera nsomba.Pakali pano, padziko lonse lapansi kutulutsa ndodo zophera nsomba za carbon fiber ndi pafupifupi 12 miliyoni, ndipo kuchuluka kwa carbon fiber yomwe imagwiritsidwa ntchito ndi pafupifupi matani 1,200.Kugwiritsa ntchito mpweya wa kaboni m'magulu a gofu kunayamba mu 1972. Pakali pano, kutulutsa kwapachaka kwa fibra de carbonmakalabu a gofu padziko lonse lapansi ndi pafupifupi mabotolo 40 miliyoni, ndipo kuchuluka kwa mpweya wa carbon ndi wofanana ndi matani 2,000.Kugwiritsa ntchito ma racket a tenisi kunayamba mu 1974. Tsopano, dziko lapansi linapanga pafupifupi 4.5 miliyoni za carbon fiber racket chaka chatha, ndipo kugwiritsa ntchito mpweya wa carbon kumafuna matani pafupifupi 500.Mwa zina, mpweya wa carbon umagwiritsidwanso ntchito kwambiri pamasewera otsetsereka, mabwato a chipale chofewa, ski stick, mileme ya baseball, masewera apamsewu, ndi masewera apanyanja.
Kuzindikira kupepuka, kukana kutopa, kukana dzimbiri ndi zinthu zina za carbon fiber, zimagwiritsidwa ntchito kwambiri muzamlengalenga.M'malo owulukira mumlengalenga, ma fiber apamwamba a modulus carbon agwiritsidwa ntchito m'ma satelayiti ochita kupanga chifukwa cha kulemera kwawo (kukhazikika) komanso kusinthasintha kwamafuta okhazikika.M’zaka zaposachedwapa, akhala akugwiritsidwa ntchito m’masetilaiti olankhulana monga iridium.
The akamaumba pawiri makamaka wosanganiza mu thermoplastic utomoni mu mawonekedwe agalasi CHIKWANGWANI akanadulidwa zingwe, yomwe imakhala ndi mphamvu yolimbitsa, anti-static and electromagnetic wave shielding, ndipo imagwiritsidwa ntchito kwambiri pazida zapakhomo, zipangizo zamaofesi, ma semiconductors ndi madera ena.
3.Kupanga zinthu za carbon fiber m'dziko langa
Kupanga ndi kugwiritsa ntchito mpweya wa carbon m'dziko langa kudakali koyambirira.Mphamvu yopanga mpweya wa m'nyumba imakhala pafupifupi 0.4% ya zomwe zimatulutsidwamkulu ntchito carbon CHIKWANGWANI nsalupadziko lapansi, ndipo zoposa 90% ya zinthu zapakhomo zimadalira katundu wochokera kunja.Makhalidwe a PAN precursor nthawi zonse akhala akulepheretsa kupanga kwakukulu kwamakampani opanga kaboni m'dziko langa.Kuonjezera apo, chifukwa chakuti mpweya wa carbon wakhala ukugwiritsidwa ntchito ngati chinthu chofunika kwambiri, mayiko otukuka sanagwirizane ndi mayiko akunja.Chifukwa chake, akatswiri azamakampani amakhulupirira kuti kulimbikitsa kafukufuku woyambira ndiye maziko aukadaulo komanso njira yoyambira yopangira makampani apanyumba a carbon fiber.
Dziko langa linayamba kuphunzira za carbon fiber kuyambira 1960s mpaka 1970s, pafupifupi kuyenda ndi dziko.Pambuyo pazaka zopitilira 30 zogwira ntchito molimbika, kampani yaku Japan ya Toray yapanga zinthu za carbon fiber pafupi ndi mlingo wa T300, koma zotulukapo ndi mtundu wake sizingakwaniritse zofuna zapakhomo, zomwe zili kutali ndi mayiko akunja.Poyerekeza ndi mlingo mayiko patsogolo, mavuto apamwamba a m'banja mpweya CHIKWANGWANI ndi otsika mpweya CHIKWANGWANI mphamvu, osauka yunifolomu ndi bata, ndi mlingo chitukuko ndi pafupifupi zaka 20 mpaka 30 kumbuyo kwa mayiko otsogola, ndi sikelo kupanga ndi yaing'ono, zipangizo luso. yabwerera m'mbuyo, ndipo kupanga bwino ndi kotsika.
Pakadali pano, mphamvu yapadziko lonse lapansi yopanga fibra de carbon pret ndi pafupifupi matani 35,000, ndipo kufunikira kwapachaka pamsika waku China ndi pafupifupi matani 6,500.Ndiwogula wamkulu wa carbon fiber.Komabe, China chotulutsa mpweya CHIKWANGWANI mu 2007 anali pafupifupi 200 matani, ndipo makamaka otsika ntchito mankhwala.Makampani ambiri amadalira katundu wochokera kunja, ndipo mtengo wake ndi wokwera mtengo kwambiri.Mwachitsanzo, msika wamba wa T300 ulibe chithandizo chaukadaulo chokhala ndi ufulu wodziyimira pawokha waluso, ndipo mabizinesi apakhomo sanadziwebe ukadaulo wathunthu wa carbon fiber core.Ubwino, ukadaulo ndi kuchuluka kwa kaphatikizidwe ka carbon fiber m'dziko langa ndizosiyana kwambiri ndi zomwe zili m'maiko akunja.Pakati pawo, ukadaulo wapamwamba wa carbon fiber umayendetsedwa ndikutsekedwa ndi Japan ndi mayiko aku Western.Chifukwa chake, zimatenga nthawi yayitali kuti muzindikire kukhazikika kwa kaboni fiber.Chifukwa cha kusowa kwa msika, pakhala pali "carbon fiber fever" ku China m'zaka zaposachedwa, ndipo mabungwe ambiri ofufuza asayansi ndi mabizinesi ayambitsa kafukufuku wa carbon fiber ndi ntchito zamatani masauzande ambiri.
