Hauv ntiaj teb ntawm kev tsim cov khoom sib xyaw, cov peev txheej tseem ceeb tau siv los ua kom zoo dua cov tshuaj resin, ua kom nrawm dua, thiab kho cov fiber-rau-resin piv. Txawm li cas los xij, ib qho tseem ceeb feem ntau raug saib tsis taus kom txog thaum cov kab ntau lawm nres lossis ib pawg ntawm cov khoom tiav lawm tsis ua tiav qhov kev sim siab:qhov chaw cia khoom ntawmfiberglass roving.
Fiberglass rovingtsis yog khoom siv inert. Nws yog ib yam khoom siv uas tau tsim los ntawm kev siv tshuaj lom neeg uas muaj ntau yam tshuaj lom neeg sib xyaw ua ke uas ua lub luag haujlwm sib txuas ntawm cov iav inorganic thiab cov organic resin. Cov tshuaj lom neeg no yog qhov rhiab heev, thiab nws qhov kev puas tsuaj thaum lub sijhawm khaws cia tuaj yeem ua rau muaj kev puas tsuaj loj heev hauv kev ua haujlwm ntawm cov qauv.
Hauv phau ntawv qhia no, peb tshuaj xyuas seb qhov kub thiab txias, av noo, thiab kev khaws cia lub cev ua rau muaj kev ua tau zoo ntawm koj cov ntaub ntawv txhawb nqa li cas.
Tus Yeeb Ncuab Tsis Pom: Av noo thiab Hydrolysis
Qhov kev hem thawj loj tshaj plaws rau kev khaws ciafiberglass rovingyog dej noo. Cov iav fiber yog hydrophilic ntuj (dej-nqus). Thaum cov iav filaments lawv tus kheej yog ruaj khov, lubqhov system ntsuas qhov loj me—tus choj tshuaj uas tso cai rau cov resin "ntub tawm" thiab khi rau cov fiber—yog qhov yooj yim rauhydrolysis.
Thaum twgiav fiberkev mus ncigkhaws cia rau hauv qhov chaw muaj av noo siab:
Kev puas tsuaj ntawm qhov loj me:Cov dej noo ua rau cov tshuaj sib txuas hauv qhov ntsuas me me tawg, ua rau nws tsis muaj txiaj ntsig zoo rau kev txhawb nqa kev nplaum.
Kev ntub dej tsis zoo:Thaum lub sijhawm tsim khoom, cov resin tsis nkag mus rau hauv cov fiber bundle tag nrho, ua rau "qhuav me ntsis" thiab voids hauv qhov kawg composite.
Kev Ua Haujlwm Capillary:Yog tias qhov kawg ntawm cov bobbins raug nthuav tawm, cov dej noo tuaj yeem rub mus tob rau hauv pob khoom los ntawm kev ua haujlwm capillary, ua rau kev ua haujlwm tsis sib xws thoob plaws hauv lub yob.
Kev Hloov Pauv Kub thiab Kev Hloov Chaw Loj
Thaumiav fibermuaj kev tiv taus cua sov siab, qhov kev ntsuas qhov loj me tsis ua. Yog tias lub tsev rau khoom raug cua sov heev (saum toj no 35 ° C / 95 ° F), ib qho xwm txheej hu uakev hloov pauv qhov loj metej zaum yuav tshwm sim. Cov tshuaj txheej no yuav txav tau me ntsis, sib sau ua ke rau hauv qab ntawm lub bobbin lossis tsim "cov pob nplaum."
Ntawm qhov tod tes, khaws cia roving hauv qhov chaw khov thiab tom qab ntawd tsiv nws mus rau hauv pem teb sov ua raukev sib xyaw ua keQhov dej noo sai sai no ntawm qhov chaw ntawm cov fiber yog qhov ua rau muaj kev tawg hauv cov kav dej thiab cov hlab siab.
Kev Sib Piv: Qhov Zoo Tshaj Plaws piv rau Qhov Tsis Zoo Tshaj Plaws ntawm Kev Khaws Cia
Yuav pab koj pab neeg tswj xyuas zoo tshuaj xyuas koj cov chaw, saib cov lus qhia hauv qab no rau cov qauv ntsuas kev lag luam.
Cov Qauv Cia Khoom Fiberglass Roving
| Cov Qauv | Qhov Zoo Tshaj Plaws (Kev Xyaum Zoo Tshaj Plaws) | Cov Xwm Txheej Tsis Zoo Li Qub (Kev Pheej Hmoo Siab) | Kev Cuam Tshuam Rau Kev Ua Tau Zoo |
| Kub | 5°C txog 35°C (Ruaj khov) | Qis dua 0°C los yog siab tshaj 40°C | Kev ntsuas qhov loj ntawm kev tsiv teb tsaws chaw, cov fibers tawg, lossis cov condensation. |
| Qhov av noo sib piv | 35% txog 65% | Tshaj 75% | Hydrolysis ntawm qhov loj me, kev sib txuas tsis zoo ntawm cov resin-rau-fiber. |
| Kev Hloov Mus Rau Qhov Zoo | 24–48 teev hauv lub chaw ua haujlwm ua ntej siv. | Siv ncaj qha los ntawm qhov chaw cia khoom txias. | Cov kab nrib pleb me me hauv cov resin matrix vim yog dej noo. |
| Kev sib sau ua ke | Cov pallets qub; siab tshaj plaws 2 qhov siab (yog tsim los). | Cov bobbins xoob; qhov siab stacking siab dhau. | Kev hloov pauv ntawm lub cev ntawm cov bobbins; teeb meem kev nruj. |
| Kev Raug Teeb | Ib puag ncig tsaus ntuj los yog qis UV. | Tshav ntuj ncaj qha (nyob ze qhov rais). | Kev puas tsuaj ntawm UV ntawm cov khoom ntim khoom thiab cov tshuaj ntsuas qhov loj. |
Kev Ncaj Ncees ntawm Lub Cev: Kev Sib Sau Ua Ke thiab Kev Nyuaj Siab
Fiberglass rovingfeem ntau yog qhwv rau ntawm cov bobbins nrog kev nruj kom raug. Yog tias cov bobbins no tau khaws cia tsis raug - xws li raug teeb tsa kab rov tav yam tsis muaj kev txhawb nqa lossis raug tsoo thaum muaj qhov hnyav ntau dhau - qhov geometry sab hauv ntawm lub pob hloov pauv.
Kev hloov pauv ntawm lub zog:Cov bobbins uas raug tsoo ua rau muaj "kev them nyiaj tsis sib npaug" thaum lub sijhawm pultrusion lossis filament winding. Qhov no ua rau qee cov fibers nruj dua li lwm tus, tsim kev ntxhov siab sab hauv ntawm qhov tiav lawm uas tuaj yeem ua rau warping lossis ua tsis tiav ua ntej lub sijhawm.
Fuzz thiab tawg:Thaum cov bobbins raug thawb lossis rub hla cov plag tsev tsis ruaj khov, cov txheej sab nraud ntawm lub iav raug puas tsuaj. Cov filaments tawg no tsim "fuzz" hauv cov kab ntau lawm, uas tuaj yeem txhaws cov lus qhia thiab ua rau lub dab dej resin qias neeg.
Lub Luag Haujlwm ntawm Kev Ntim Khoom: Vim Li Cas "Thawj" Zoo Tshaj Plaws
Kev siv fiberglass zoo tshaj plawsfeem ntau xa tuaj rau hauv cov ntaub qhwv uas tiv thaiv UV nrog cov pob desiccant. Ib qho yuam kev ntau hauv cov chaw tsim khoom yog rhuav cov ntim khoom no ua ntej lub sijhawm.
Cov ntaub qhwv thawj ua peb txoj haujlwm tseem ceeb:
Kev Tiv Thaiv Dej Ntxias:Nws ua haujlwm ua lub tiv thaiv tseem ceeb tiv thaiv cov av noo ib puag ncig.
Kev Tiv Thaiv Pluav Plua Plav:Cov khoom me me (hmoov av, sawdust, lossis cov hlau shavings) los ntawm ib puag ncig Hoobkas tuaj yeem cuam tshuam rau cov tshuaj sib txuas ntawm cov iav thiab cov resin.
Kev Kaw:Nws tiv thaiv qhov roving los ntawm "sloughing" lossis poob ntawm lub bobbin thaum lub sijhawm tuav.
5 Txoj Kev Ua Zoo Tshaj Plaws rau Kev Tswj Xyuas Qhov Zoo ntawm Roving
Yuav kom ntseeg tau tias koj cov khoom siv ua haujlwm raws li tus neeg tsim khoom tau teev tseg, siv tsib txoj cai hauv tsev rau khoom no:
Ua Ntej-Hauv, Ua Ntej-Tawm (FIFO): Fiberglass rovingmuaj lub sijhawm khaws cia, feem ntau yog 6 txog 12 lub hlis. Xyuas kom tseeb tias cov khoom qub siv ua ntej kom tiv thaiv kev laus ntawm qhov loj.
Txoj Cai 24-Teev:Yuav tsum nqa cov khoom roving los ntawm lub tsev rau khoom mus rau hauv chav tsim khoom tsawg kawg yog 24 teev ua ntej siv. Qhov no ua rau cov khoom siv mus txog "kev sib npaug ntawm qhov kub thiab txias," tiv thaiv kom tsis txhob muaj dej noo thaum lub pob qhib.
Chaw Cia Khoom Siab:Tsis txhob muab cov pallets ntawm cov khoom siv roving tso rau ntawm pem teb uas muaj cov pob zeb ua ke, vim tias cov khoom no yuav "nqus" cov dej noo. Siv cov racking lossis cov pallets ntoo.
Cov Khoom Siv Sib Txuas Ib Nrab:Yog tias lub bobbin tsuas yog siv ib nrab xwb, tsis txhob cia nws tshwm sim rau ntawm lub tshuab. Rov qhwv nws nrog yas ua ntej xa rov qab mus rau qhov chaw cia khoom.
Saib xyuas nrog Hygrometers:Nruab cov ntsuas kub thiab av noo digital hauv koj cov chaw khaws khoom. Cov ntaub ntawv no muaj nqis heev thaum daws teeb meem qhov teeb meem ntawm kev tsim khoom nce siab sai sai.
Xaus Lus: Tiv Thaiv Koj Cov Nyiaj Txiag
Fiberglass rovingyog ib yam khoom siv ua tau zoo heev, tab sis nws txoj kev ua tau zoo tsis yooj yim puas tsuaj kom txog thaum nws kho tau hauv cov resin matrix. Los ntawm kev kho cov xwm txheej cia khoom nrog tib theem ntawm kev tshuaj xyuas zoo li koj cov kev tsim khoom, koj tuaj yeem txo cov nqi pov tseg, txhim kho qhov sib xws ntawm ib feem, thiab xyuas kom meej tias koj cov khoom sib xyaw ua haujlwm tau ntev.
