Nrog rau kev txhim kho cov khoom tsim kev tsim tshuab, nrog rau kev nkag siab sib txuas ntawm cov khoom lag luam hla kev lag luam hauv tsheb ciav hlau hla kev hauv tsheb thauj khoom tau maj mam nthuav dav. Cov hom, qib kawm qib thiab kev ua haujlwm ntawm cov khoom siv sib xyaw uas tau siv los kuj tau txhim kho tas li.
Cov hom ntawm cov khoom siv sib xyaw uas tau siv hauv tsheb ciav hlau hla kev muaj:
(1) nruj thiab sib zog semi-nruj undaturated polyester retin frp;
(2) Phenolic resin iav fiber ntau ntxiv txog yas;
(3) Cov nplaim hluav taws ruretive flame retaturant unsaturated polyester resin frp nrog lub zog siab;
(4) Cov nplaim hluavtaws ntxiv tsis tau txais Polyester Resin iav Fiber ntau ntxiv dag zog;
(5) Cov khoom siv fiber carbon fiber ntau.
Los ntawm cov khoom lag luam yog:
(1) Tes nteg-up frp seem;
(2) Moulded Frp Qhov;
(3) FRP qhov chaw ntawm cov qauv xuab zeb;
(4) Carbon Fiber tshooj.
Daim ntawv thov ntawm Frp hauv kev tsheb ciav hlau hla kev
1. Kev thov ntxov ntawm Frp hauv kev tsheb ciav hlau hla
Daim ntawv thov ntawm Frp hauv kev hloov tsheb kauj vab pib thaum xyoo 1980s, thiab nws tau siv thawj zaug tsim tawm 140km / h tsawg-ceev hluav taws xob tsheb ciav hlau. Cov kev ntsuas ntawm daim ntawv thov yog suav nrog:
● Lub vaj huam sib luag phab ntsa;
● Sab hauv phaj;
● Los sib sau cov iav fiber ntau txhawb nqa yas tsev dej;
Lub ntsiab lus thov lub hom phiaj nyob rau lub sijhawm ntawd yog Katsukiyogi. Hom FRP siv yog unsaturated polyester resin frp.
2. Batch daim ntawv thov ntawm Frp ntawm tsheb ciav hlau hla kev
Lub batch daim ntawv thov ntawm Frp ntawm Rail tsheb thauj mus los thiab nws cov lus tiav qib pib tau tshwm sim hauv xyoo 1990. Nws yog tsuas yog siv rau kev tsim cov kev tsheb thauj neeg cov neeg caij tsheb thiab nroog tsheb ciav hlau:
Vaj huam sib luag sab hauv ntawm chav qhua;
● Sab hauv phaj;
Ke Fuab Fiber Reinferced Yas Yas Wolding;
Inforty Grey Fiber cuam txhawb nqa dej yas chav;
Infortic Giber Fiber ntxiv txhawb cov ntxhua khaub ncaws yas;
Frp cua txias duct, pov tseg use use;
● rooj lossis rooj zaum.
Lub sijhawm no, lub ntsiab ntawv thov lub hom phiaj tau hloov pauv los ntawm hloov ntoo los txhim kho qib tsheb; Hom FRP siv tseem yog feem ntau tsis muaj tseeb polyester resin frp.
3. Nyob rau hauv xyoo tsis ntev los no, daim ntawv thov ntawm Frp hauv cov tsheb ciav hlau
Txij li thaum pib ntawm lub xyoo pua no, frp tau siv dav ntau siv hauv tsheb ciav hlau hla kev. Ntxiv rau kev siv nyob rau hauv kev tsim khoom ntawm cov khoom siv ntau yam, nws tseem muaj siv dav hauv kev tsim khoom ntawm:
● Ris vov;
Ib tug tshiab cua ciav ntawm lub ru tsev;
● Ntau ntau yam nrog cov duab ua nyuaj hauv lub tsheb, suav nrog peb-sab nkhaus sab hauv vaj huam sib luag thiab sab vaj tsev vov; Npog panels ntawm ntau cov qauv tshwj xeeb; Cov iav fiber cuam txhawb nqa yas honeycomb phab ntsa phab ntsa; hniav zoo nkauj.
Lub hom phiaj tseem ceeb ntawm FRP daim ntawv thov nyob rau theem no yog tsim cov khoom siv nrog cov kev ua haujlwm tshwj xeeb lossis cov qauv sib txawv. Tsis tas li ntawd, cov hluav taws kub tiv thaiv frp thov nyob rau hauv theem no kuj tau txhim kho. Rov qab siv cov nplaim hluavtaws rethaturant polyester resatin frp tau siv dav, thiab daim ntawv thov ntawm phenolic resin frp tau maj mam poob qis.
4. Daim ntawv thov ntawm Frp hauv High-Ceev Emu
Daim ntawv thov ntawm Frp hauv kev tsheb ciav hlau siab emus tau nkag mus rau theem paub tab. Vim tias:
(1) FRP yog siv rau hauv kev tsim cov khoom nrog cov haujlwm tshwj xeeb, thiab cov qauv hloov kho tshiab, thiab kaw cov pob zeb hauv av, ru tsev aerodynamic shrouds, thiab lwm yam..
(2) Moulded iav Fiber Reinferced Yas (SMC) tau siv dav
Kev siv cov iav iav fiber cuam tshuam txog yas los tsim cov heigh-ceev EMU neeg caij npav sab hauv muaj cov txiaj ntsig hauv qab no:
Qhov tseeb ntawm qhov tseeb ntawm cov ntu yog qhov siab;
● Kev tsim tau zoo thiab cov khoom lag luam,
● Ua tiav lub teeb nyem;
Tsim kom haum rau cov engineering pawg ntau lawm.
(3) txhim kho qib ntawm Frp thov hauv lwm qhov
● Nws tuaj yeem ua rau hauv cov chaw nrog ntau yam kev raws li xav tau;
Cov tsos zoo yog qhov zoo dua, thiab cov duab thiab qhov tseeb qhov tseeb ntawm cov ntu yog ntau dua;
● Cov xim nto thiab qauv tuaj yeem hloov kho tib lub sijhawm.
Nyob rau lub sijhawm no, daim ntawv thov ntawm Frp suav nrog kev paub txog cov haujlwm tshwj xeeb thiab cov hom phiaj, thiab qib siab dua xws li coj lub teeb thiab lub teeb yuag.
