"Txheej txheem winding filament" yog ib txoj kev tsim khoom siv rau kev tsim cov qauv cylindrical, xws li cov kav dej, cov tank, thiab cov raj, siv cov khoom sib xyaw. Hauv cov ntsiab lus no, "fiberglass roving" txhais tau hais tias cov pob ntawm cov xov fiberglass uas tsis sib txuas uas siv rau hauv cov txheej txheem winding filament.
Kev Npaj: Lub fiberglass roving yog npaj los ntawm kev unwinding nws los ntawm spools. Lub roving ces raug coj los ntawm lub dab dej resin, qhov twg nws yog impregnated nrog cov resin xaiv (piv txwv li, epoxy, polyester, lossis vinylester).
Kev Sib Tw: Cov khoom siv roving impregnated yog qhwv rau ntawm lub mandrel tig hauv tus qauv uas tau teem tseg. Tus qauv sib tw (piv txwv li, helical lossis hoop winding) thiab lub kaum sab xis ntawm kev sib tw raug xaiv raws li cov khoom xav tau ntawm cov khoom kawg.
Kev Kho: Thaum lub winding tiav lawm, cov resin yuav tsum tau kho kom tawv thiab khov kho. Qhov no tuaj yeem ua tiav ntawm chav tsev kub lossis hauv qhov cub, nyob ntawm seb lub cev resin siv.
Tso Tawm: Tom qab kho, cov qauv qhov txhab raug tshem tawm ntawm lub mandrel, ua rau muaj cov qauv sib xyaw ua ke, cylindrical.
Kev Xaus: Cov khoom kawg yuav dhau los ntawm cov txheej txheem ntxiv xws li kev txiav, kev khawb, lossis kev txheej, nyob ntawm nws daim ntawv thov.
Cov txheej txheem filament winding siv fiberglass roving muaj ntau qhov zoo:
Lub Zog Siab: Vim yog qhov xwm txheej tas mus li ntawm cov fibers thiab lub peev xwm los taw qhia lawv hauv cov kev taw qhia xav tau, cov khoom kawg muaj lub zog siab hauv cov kev taw qhia ntawd.
Kev Kho Kom Haum: Tus qauv winding thiab fiber orientation tuaj yeem kho kom haum rau lub zog tshwj xeeb thiab kev nruj.
Kev Lag Luam: Rau kev tsim khoom loj, filament winding tuaj yeem pheej yig dua piv rau lwm cov txheej txheem tsim khoom sib xyaw.
Kev Siv Tau Ntau Yam: Muaj ntau yam khoom uas muaj ntau qhov ntau thiab tsawg thiab duab sib txawv.
Fiberglass roving yog qhov tseem ceeb rau cov txheej txheem filament winding, muab lub zog, kev ywj pheej, thiab kev siv nyiaj tsawg rau cov khoom sib xyaw ua ke.
Fiberglass roving applicant hauv FRP yeeb nkab
Cov Khoom Siv Txhawb Nqa: Cov iav fiber yog cov khoom siv txhawb nqa feem ntau siv rau hauv cov kav dej FRP. Nws muab cov kav dej nrog lub zog thiab kev ruaj khov.
Kev Tiv Thaiv Kev Xeb: Piv rau ntau lwm yam khoom siv, cov kav dej FRP muaj kev tiv thaiv kev xeb zoo dua, feem ntau yog vim lawv cov qauv iav fiber-reinforced. Qhov no ua rau cov kav dej FRP tshwj xeeb tshaj yog rau cov tshuaj lom neeg, roj, thiab roj av, qhov twg kev xeb yog qhov teeb meem loj.
Qhov Sib Nqus: Cov kav dej FRP uas muaj iav fiber ntau dua li cov kav hlau lossis hlau ib txwm muaj, ua rau kev teeb tsa thiab kev thauj mus los yooj yim dua.
Kev Tiv Thaiv Kev Hnav: Cov kav dej FRP muaj kev tiv thaiv kev hnav zoo heev, ua rau lawv muaj txiaj ntsig zoo hauv kev thauj mus los ntawm cov kua dej uas muaj xuab zeb, av, lossis lwm yam khoom siv abrasives.
Cov Khoom Siv Rwb Thaiv Kub: Cov kav dej FRP muaj cov khoom rwb thaiv kub zoo, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev siv hluav taws xob thiab kev sib txuas lus.
Kev Lag Luam: Txawm hais tias tus nqi pib ntawm cov kav dej FRP yuav siab dua li qee cov khoom siv ib txwm muaj, lawv lub neej ntev, kev saib xyuas tsawg, thiab kev kho yuav ua rau lawv pheej yig dua hauv cov nqi ntawm lub neej tag nrho.
Kev Tsim Qauv Yooj Yim: Cov kav dej FRP tuaj yeem hloov kho kom tau raws li qhov xav tau ntawm cov ntawv thov tshwj xeeb, txawm tias yog qhov loj me, ntev, lossis tuab.
Hauv kev xaus lus, kev siv cov iav fiber hauv cov kav dej FRP muab ntau yam kev lag luam nrog kev daws teeb meem pheej yig, ruaj khov, thiab ua haujlwm tau zoo.
Vim li cas fiberglass roving hauv FRP yeeb nkab
Lub Zog thiab Kev Rigid: Fiberglass roving muab cov kav dej FRP nrog lub zog tensile siab thiab kev rigidity, xyuas kom meej tias cov kav dej tswj lawv cov duab thiab kev ua haujlwm zoo nyob rau hauv ntau yam kev ua haujlwm.
Kev Txhawb Nqa Kev Taw Qhia: Cov fiberglass roving tuaj yeem muab tso rau kev taw qhia kom muab kev txhawb nqa ntxiv rau hauv cov kev taw qhia tshwj xeeb. Qhov no tso cai rau cov kav dej FRP kom raug kho rau cov kev xav tau tshwj xeeb.
Cov Khoom Zoo Wetting: Fiberglass roving muaj cov khoom zoo wetting nrog cov resins, xyuas kom meej tias cov resin impregns cov fiber thaum lub sijhawm ntau lawm, ua tiav qhov kev txhawb nqa zoo tshaj plaws.
Kev Siv Nyiaj Txiag: Piv rau lwm cov ntaub ntawv txhawb nqa, fiberglass roving yog qhov kev xaiv pheej yig, muab cov kev ua tau zoo yam tsis ntxiv cov nqi tseem ceeb.
Kev Tiv Thaiv Kev Xeb: Fiberglass roving nws tus kheej tsis xeb, tso cai rau FRP cov kav dej ua haujlwm zoo hauv ntau qhov chaw corrosive.
Cov Txheej Txheem Tsim Khoom: Siv fiberglass roving ua kom yooj yim thiab ua kom cov txheej txheem tsim khoom ntawm FRP cov kav dej yooj yim dua, vim tias qhov roving tuaj yeem yooj yim qhwv ib puag ncig cov pwm tsim khoom thiab kho ua ke nrog cov roj hmab.
Yam Ntxwv Sib Nqus: Fiberglass roving muab qhov kev txhawb nqa rau FRP cov kav dej thaum tseem khaws cia qhov sib dua, ua rau kev teeb tsa thiab kev thauj mus los yooj yim dua.
Hauv kev xaus, daim ntawv thov ntawm fiberglass roving hauv FRP cov kav dej yog vim nws muaj ntau yam zoo, suav nrog lub zog, kev nruj, kev tiv thaiv corrosion, thiab kev siv nyiaj tsawg.
Cov txheej txheem txuas ntxiv mus tas li yog tias cov hlau txuas txav mus los rov qab - thiab - tawm mus ncig. Cov txheej txheem Fiberglass winding, compound, xuab zeb suav nrog thiab kho thiab lwm yam tiav ntawm kev txav mus rau pem hauv ntej mandrel core thaum kawg cov khoom raug txiav ntawm qhov ntev thov.
