xov xwm

Nrog rau txoj kev loj hlob ntawm kev tsim khoom siv technology, nrog rau kev nkag siab tob tob thiab kev nkag siab ntawm cov ntaub ntawv sib xyaw hauv kev lag luam tsheb ciav hlau, nrog rau kev ua tiav thev naus laus zis ntawm kev tsheb ciav hlau thauj mus los hauv kev lag luam, daim ntawv thov muaj peev xwm ntawm cov ntaub ntawv sib xyaw hauv tsheb ciav hlau muaj maj mam nthuav.Hom, qib thiab qib kev kawm ntawm cov khoom siv sib xyaw siv kuj tseem txhim kho tas li.

Daim ntawv thov ntawm FRP hauv Rail Transit Tsheb

1. Thaum ntxov daim ntawv thov ntawm FRP nyob rau hauv cov tsheb thauj mus los

Daim ntawv thov ntawm FRP hauv kev tsheb ciav hlau tsheb thauj mus los tau pib thaum xyoo 1980, thiab nws tau siv thawj zaug hauv kev tsim hluav taws xob hauv tsev 140km / h qis-ceev tsheb ciav hlau.Scope ntawm daim ntawv thov feem ntau suav nrog:

● puab phab ntsa vaj huam sib luag;

● puab sab saum toj phaj;

● Sib dhos iav fiber reinforced yas tso zis tso quav;

Lub hom phiaj tseem ceeb ntawm daim ntawv thov nyob rau lub sijhawm ntawd yog Katsukiyogi.Hom FRP siv yog unsaturated polyester cob FRP.

2. Batch daim ntawv thov ntawm FRP ntawm cov tsheb thauj mus los

Daim ntawv thov batch ntawm FRP ntawm tsheb thauj mus los thiab nws cov kev loj hlob zuj zus tshwm sim hauv xyoo 1990.Nws yog tsuas yog siv rau kev tsim cov tsheb ciav hlau neeg caij tsheb thiab tsheb ciav hlau hauv nroog:

Sab hauv phab ntsa vaj huam sib luag ntawm chav qhua;

● Sab saum toj phaj;

Sib dhos iav fiber reinforced yas tso zis tso quav;

Integral iav fiber reinforced yas chav dej;

Integral iav fiber reinforced yas ntxhua khaub ncaws;

FRP cua txias duct, khib nyiab duct;

● Lub rooj zaum lossis lub rooj zaum ncej.

Lub sijhawm no, lub hom phiaj tseem ceeb ntawm daim ntawv thov tau hloov pauv los ntawm kev hloov ntoo mus rau kev txhim kho qib ntawm cov tsheb;Cov hom FRP siv tseem yog cov tsis muaj xim polyester resin FRP.

3. Nyob rau hauv xyoo tas los no, daim ntawv thov ntawm FRP hauv tsheb ciav hlau

Txij li thaum pib ntawm lub xyoo pua no, FRP tau siv dav hauv tsheb thauj mus los.Ntxiv nrog rau kev siv hauv kev tsim cov khoom lag luam uas tau hais los saum no, nws kuj tau siv dav hauv kev tsim khoom:

● Cov ntaub thaiv npog;

Ib lub tshuab cua tshiab ntawm lub ru tsev;

● Ntau yam khoom siv nrog cov duab nyuaj hauv lub tsheb, suav nrog peb-seem nkhaus sab hauv phab ntsa panels thiab sab ru tsev panels;npog panels ntawm ntau yam tshwj xeeb duab;iav fiber reinforced yas honeycomb phab ntsa panels;kho kom zoo nkauj qhov chaw.

Lub hom phiaj tseem ceeb ntawm FRP daim ntawv thov nyob rau theem no yog los tsim cov khoom siv nrog cov kev cai tshwj xeeb lossis cov qauv tsim qauv.Tsis tas li ntawd, qhov hluav taws kub tsis kam ntawm FRP thov nyob rau theem no kuj tau txhim kho.Reactive thiab additive nplaim retardant unsaturated polyester cob FRP tau dav siv, thiab daim ntawv thov ntawm phenolic resin FRP tau maj txo.

4. Daim ntawv thov ntawm FRP hauv high-ceev EMU

Daim ntawv thov ntawm FRP nyob rau hauv high-ceev railway EMUs tau nkag mus rau hauv ib tug paub tab theem.vim:

(1) FRP yog siv rau hauv kev tsim cov khoom siv nrog cov haujlwm tshwj xeeb, cov duab thiab cov qauv tsim, thiab kev ua haujlwm zoo heev uas tuaj yeem tiv taus cov khoom loj, xws li FRP cov khoom siv hluav taws xob, pem hauv ntej-kawg qhib thiab kaw mechanisms, ru tsev aerodynamic shrouds, lwm..

(2) Moulded iav fiber reinforced yas (SMC) tau siv dav

Kev siv molded iav fiber reinforced yas los tsim high-ceev EMU neeg nrog caij sab hauv phab ntsa panels nyob rau hauv batch muaj cov nram qab no zoo:

Qhov tseeb qhov tseeb ntawm qhov chaw yog siab;

● Kev tsim khoom zoo thiab qib khoom,

● Tau lub teeb yuag;

● Tsim nyog rau engineering loj ntau lawm.

(3) Txhim kho qib ntawm FRP siv rau lwm qhov chaw

●Nws tuaj yeem ua rau hauv qhov chaw nrog ntau yam textures raws li xav tau;

Cov tsos zoo yog zoo dua, thiab cov duab thiab qhov tseeb ntawm cov khoom yog siab dua;

●Nto xim thiab qauv tuaj yeem hloov kho tib lub sijhawm.

Nyob rau lub sijhawm no, daim ntawv thov ntawm FRP suav nrog kev ua tiav ntawm cov haujlwm tshwj xeeb thiab cov duab, thiab cov hom phiaj siab dua xws li kev coj tus yam ntxwv thiab lub teeb yuag.
