Malinga ndi mmene carbon filament, n’chifukwa chiyani mtengo wa carbon fiber uli wokwera kwambiri?

Kuchita bwino kwa zinthu za carbon fiber kumapangitsa kuti ikhale yogwira ntchito kwambiri m'mafakitale ambiri.Pamene acarbon fibermankhwala amagwiritsidwa ntchito, amapezeka kuti mtengo wonse ndi wapamwamba.Malo omwe mtengo wamtengo wosweka wosweka umakhala wokwera ali ndi chochita ndi malo ambiri.Gulu lathu likuwuzani kuchokera kumalingaliro a carbon fiber.

Zopangira kaboni zomwe timaziwona ndizosiyana kwambiri ndi zida zathu za kaboni, chifukwa ulusi sungathe kupangidwa wokha, ndipo uyenera kuphatikizidwa ndi matrix a resin kuti amalize kupanga zinthu.Chimodzi mwa zifukwa zomwe mtengo wa zinthu za fiber umakhala wokwera mtengo kwambiri ndikuti mtengo wa carbon filaments ndi wokwera kwambiri, choncho choyamba tiyenera kumvetsetsa za carbon fiber tow material.

Pali mitundu itatu ya ulusi wosweka, kuphatikiza polyacrylonitrile (PAN)-based carbon fiber, pitch-based carbon fiber ndi chingamu.Mpweya wa carbon wodziwika kwambiri wa PAN ndi womwe umakhala wofala kwambiri, ndipo gawo lonse la msika likupitirira 90%, kotero thermoplastic carbon fiber yomwe ilipo panopa ikutanthauza PAN-based carbon fiber.

Polyacrylonitrile idapangidwanso koyambirira.Anapangidwa ndi Akio Kondo ku Japan mu 1959, ndipo kenako anapangidwa ndi misa ku Toray mu 1970. Polyacrylonitrile carbon filament ili ndi mphamvu zambiri komanso makhalidwe a nyenyezi yachitsanzo.Chingwe chopangidwa ndi asphalt chinapangidwa ndi yunivesite ya Gunma ku Japan ku 1965. Chojambula cha carbon fiber chimakhala ndi matenthedwe apamwamba kwambiri a 90OGPa, choncho amagwiritsidwa ntchito kwambiri pazinthu zapadera zogwirira ntchito.Viscose-based carbon fiber inkagwiritsidwa ntchito makamaka ngati zida zopangira zishango zotenthetsera zamlengalenga muzaka za m'ma 1950, komanso ndizinthu zomwe zigwiritsidwe ntchito pano.Chifukwa chake tidapeza kuti awiri oyambilira adapangidwa ndi aku Japan, ndichifukwa chake muyeso wa kuyeza kwa carbon fiber tow umachokera ku Toray carbon fiber material.

Zoonadi, kafukufuku ndi chitukuko cha carbon fiber tow precursors akupitirizabe kupita patsogolo m'zaka zaposachedwa, koma zotsatira zake sizinachitikebe.Masiku ano, PAN-based akadali chinsinsi.Popanga mpweya wa carbon filaments, zokolola za carbon za ma precursors atatu zimatha kufika kuposa B80%.Mwachidziwitso, mtengo wa carbon fiber filaments wotere udzakhala wotsika, koma kupanga phula kumayenera kukonzedwa ndikusinthidwa.Izi zidzakulitsa kwambiri ndalama zopangira ndikuchepetsa zokolola mpaka 30%.Chifukwa chake omwe ali ndi PAN akadali otchuka kwambiri.

Ndiye tiyeni tiwone za PAN carbon fiber yomwe imagwiritsidwa ntchito kwambiri.Mtengo wa PAN-based carbon fiber ndi wotsika kwambiri kuposa wa asphalt-based carbon fiber, ndipo ungagwiritsidwe ntchito m'madera ambiri.Mtengo wa CHIKWANGWANI chochokera ku PAN pa ma satelayiti ndi wokwera mpaka 200 yen/kg, pomwe mtengo wa carbon fiber pamagalimoto ndi wotsika kwambiri mpaka 2,000 yen/kg.

Kenako timagwiritsabe ntchito zinthu za Toray za carbon fiber monga maziko.Apa, ulusi wosweka wopangidwa ndi PAN umagawidwa kukhala zazikulu ndi zazing'ono.Mwachitsanzo, mtengo wa 3K wamba ndi 50-70 US dollars/kg, ndipo mtengo wa 6K ndi 4-50 US dollars/kg.Chifukwa chake, titha kumvetsetsanso chifukwa chake zingwe zazing'ono zimagwiritsidwa ntchito kwambiri m'magawo ochita bwino kwambiri.

Choncho, timati mtengo wa carbon fiber udzakhala wokwera mtengo kwambiri.Sizopanda chifukwa kuti ali ndi zambiri kuchita ndi zipangizo.Kuonjezera apo, mtengo wa carbon fiber ndi wokwera kwambiri, ndipo umagwirizana kwambiri ndi mfundo yakuti zinthu zathu za carbon fiber zimafuna ntchito ndi zipangizo zambiri.
