Ngokombono we-carbon filament, kutheni ixabiso le-carbon fiber liphezulu?

Ukusebenza okuphezulu kwezinto ze-carbon fiber kwenza kube nokusebenza okuphezulu kakhulu kwesicelo kumashishini amaninzi.Xa icarbon fiberimveliso isetyenziswa, kufumaniseka ukuba ixabiso lilonke liphezulu.Indawo apho ixabiso lemveliso yefayibha eyaphukileyo liphezulu linento yokwenza neendawo ezininzi.Iqela lethu liya kukuxelela ngokwembono ye-carbon fiber.

Iimveliso ze-carbon fiber esizibonayo ngokwenene zahluke kakhulu kwizinto zethu ze-carbon fiber, kuba iifayibha azikwazi ukuveliswa zodwa, kwaye kufuneka zidibaniswe ne-resin matrix ukugqiba ukuveliswa kweemveliso.Esinye sezizathu zokuba kutheni ixabiso leemveliso zefayibha lixabisa kakhulu kukuba ixabiso le-carbon filaments liphezulu kakhulu, ngoko ke kufuneka siqonde kuqala i-carbon fiber tow material.

Kukho iintlobo ezintathu ze-fiber tow ephukile, kuquka i-polyacrylonitrile (PAN)-based carbon fiber, i-pitch-based carbon fiber kunye ne-gum-based carbon fiber.Eyona nto ixhaphakileyo ye-PAN-based carbon fiber ngokwenene ixhaphake kakhulu, kwaye isabelo semarike siphela singaphezulu kwe-90%, ngoko ke i-carbon fiber ye-thermoplastic yangoku ibhekisela kwi-PAN-based carbon fiber.

I-Polyacrylonitrile nayo yaqanjwa kwasekuqaleni.Yasungulwa ngu-Akio Kondo eJapan ngo-1959, kwaye emva koko iveliswa ngobuninzi kwiToray ngo-1970. Yonke i-polyacrylonitrile carbon filament inamandla aphezulu kakhulu kunye neempawu zeenkwenkwezi zemodeli.I-fiber esekelwe kwi-asphalt yaphuhliswa yiYunivesithi yaseGunma eJapan ngo-1965. Le carbon fiber tow ine-conductivity ephezulu kakhulu ye-thermal ephezulu njenge-90OGPa, ngoko isetyenziswa kakhulu kwizinto ezikhethekileyo zokusebenza.Ifayibha yekhabhoni esekwe kwiViscose yayisetyenziswa ikakhulu njengesixhobo sokukhusela ubushushu kwiziphekepheke ngeminyaka yoo-1950, kwaye ikwayimathiriyeli eza kusetyenziswa ngoku.Ke siye safumanisa ukuba ezimbini zokuqala zayilwa ngamaJapan, yiyo loo nto umgangatho wokulinganisa ukusebenza kwekhabhoni yefiber tow usekwe kwiToray carbon fiber material.

Ngokuqinisekileyo, uphando kunye nophuhliso lwe-carbon fiber tow precursors luye lwaqhubeka luqhubela phambili kwiminyaka yamuva nje, kodwa umphumo wonke awukasebenzi.Namhlanje, iPAN-based iseyeyona nto iphambili.Ekuveliseni i-carbon filaments, imveliso yekhabhoni ye-precursors emithathu inokufikelela ngaphezu kwe-B80%.Ngokwethiyori, ixabiso le-carbon fiber filaments ngokuqinisekileyo liya kuba liphantsi, kodwa ukuveliswa kwe-pitch-based kufuneka kucocwe kwaye kulungiswe.Le nkqubo iya kwandisa kakhulu iindleko zemveliso kwaye inciphise isivuno ukuya kwi-30%.Ke ezi zisekwe kwiPAN zisathandwa kakhulu.

Ngoko ke makhe sijonge kwiPAN carbon fiber esetyenziswa ngokubanzi.Ixabiso le-PAN-based fiber fiber liphantsi kakhulu kune-asphalt-based carbon fiber, kwaye inokusetyenziswa kwiinkalo ezininzi.Ixabiso le-PAN-based fiber kwi-satellites liphezulu njenge-200 yen / kg, ngelixa ixabiso le-carbon fiber kwiimoto liphantsi njenge-2,000 yen / kg.

Emva koko sisasebenzisa iToray's carbon fiber material njengesiseko.Apha, i-PAN-based based fibers ephukileyo ihlulwe ibe yi-tows enkulu kunye encinci.Ngokomzekelo, iindleko ze-3K eziqhelekileyo ziyi-50-70 yeedola zase-US / kg, kunye neendleko ze-6K yi-4-50 yeedola zase-US / kg.Ke ngoko, sinokuqonda ukuba kutheni iitowuli ezincinci zisetyenziswa kakhulu kumasimi asebenza kakhulu.

Ngoko ke, sithi ixabiso le-carbon fiber liya kuba libiza kakhulu.Akunjalo ngaphandle kwesizathu ukuba inento eninzi yokwenza nezinto eziluhlaza.Ukongeza, ixabiso lemveliso ye-carbon fiber liphezulu kakhulu, kwaye linento eninzi yokwenza nenyaniso yokuba iimveliso zethu ze-carbon fiber zifuna umsebenzi omningi kunye nezixhobo.
