Hauv lub ntiaj teb niaj hnub no uas muaj kev tsim khoom thiab kev tsim kho, kev nrhiav cov ntaub ntawv uas sib dua, muaj zog heev, thiab pheej yig yeej tsis muaj qhov kawg. Lub plawv ntawm qhov kev hloov pauv no yog cov ntaub ntawv uas tsis muaj zog tab sis muaj zog:fiberglass strand txiav.
Txawm koj yog tus neeg cog lus ua vaj tse uas tab tom nrhiav kev tiv thaiv kom tsis txhob muaj kab nrib pleb lossis tus neeg tsim khoom sib xyaw ua cov khoom siv tsheb ua tau zoo, nkag siab txog qhov sib txawv ntawmfiberglass txiav strandsyog qhov tseem ceeb. Phau ntawv qhia no qhia tob txog cov hom, kev siv, thiab cov txiaj ntsig ntawm cov cuab yeej me me tab sis muaj zog no.
Dab tsi yog Chopped Strands tiag tiag?
Cov xov txiavyog tsim los ntawm kev txiav cov iav fiber filaments mus rau hauv qhov ntev tshwj xeeb, feem ntau yog txij li 3 hli (1/8 ") txog 50 hli (2 "). Cov strands no tau coated nrog ib tug tshwj xeeb "sizing" (ib tug tshuaj kho nto) uas ua kom lawv sib txuas zoo meej nrog cov khoom matrix - nws yog yas resin, gypsum, lossis cement.
Ob Lub Ncej: E-Iav vs. AR-Iav
Thaum nrhiav cov iav fiber txiav strands, qhov sib txawv tseem ceeb tshaj plaws yog hom iav siv:
1.E-Iav (Iav Hluav Taws Xob):Qhov no yog tus qauv kev lag luam rau feem ntau ntawm cov ntawv thov sib xyaw.E-iav txiav cov xov hlaumuab kev rwb thaiv hluav taws xob zoo heev thiab lub zog kho tshuab siab. Lawv feem ntau siv nrog cov thermoset resins (polyester, epoxy) los tsim txhua yam los ntawm lub nkoj hulls mus rau cov vaj huam sib luag hluav taws xob.
2.AR-Iav (Alkali-Resistant):Tsim tshwj xeeb rau kev lag luam kev tsim kho, AR fiberglass strands txiavmuaj Zirconia (ZrO2). Qhov no tso cai rau lawv kom tiv taus qhov chaw muaj alkali ntau ntawm Portland cement, uas yuav "noj" lossis ua rau E-iav puas tsuaj.
Cov Ntawv Thov Tseem Ceeb: Txij Li Cov Pob Zeb Ua Los Ntawm Cov Khoom Siv High-Tech Composites
1. Cov Fiberglass Txiav Rau Kev Txhawb Nqa Pob Zeb
Ib qho ntawm cov khoom siv nrov tshaj plaws rau cov khoom siv no yog nyob rau hauv kev tsim kho.Fiberglass strands rau concreteua raws li kev txhawb nqa thib ob. Tsis zoo li cov hlau mesh, uas tsuas yog muab lub zog hauv ib lub dav hlau,cov fiberglass strands txiav rau cov pob zeb ua vaj tsetsim kom muaj ntau txoj kev txhawb nqa.
Kev Tswj Xyuas Kev Ntsws:Lawv txo qhov "kev tawg ntawm cov yas shrinkage" uas tshwm sim thaum cov pob zeb qhuav.
Kev Cuam Tshuam:Cov iav AR ua rau lub zog nqus ntawm cov pob zeb ua vaj tse thiab cov vaj huam sib luag GFRC (Iav Fiber Reinforced Concrete) zoo nkauj nce ntxiv.
Tsis Muaj Kev Xeb:Tsis zoo li cov hlau,iav txiav cov xovyuav tsis xeb, ua rau lawv zoo tagnrho rau cov chaw marine lossis cov chaw noo noo siab.
2. Kev Siv Thermoplastic thiab Thermoset Reinforcement
Hauv kev lag luam yas,cov iav fiber uas raug txiavyog sib xyaw nrog cov resins los tsim Bulk Molding Compounds (BMC) thiab Sheet Molding Compounds (SMC). Cov no yog siv los tsim:
Cov khoom siv hauv tsheb (dashboards, bumpers).
Cov tsev nyob ntawm cov khoom siv.
Cov yeeb nkab khoom siv.
Nkag Siab Txog Qhov Loj: Vim Li Cas 1/4 "Chopted Fiberglass Tseem Ceeb
Qhov ntev ntawm cov fiber, xws li1/4 fiberglass strand txiav(kwv yees li 6 hli), tsis yog kev xaiv random. Nws dictates qhov kev ua tau zoo thiab qhov tiav ntawm cov khoom kawg.
Tsim tshwj xeeb rau cov ntawv thov siab precision,1/4" (6 hli) cov fiberglass txiav ua tej daim me mezoo heev hauv kev ua tiav qhov chaw zoo nkauj, du heev rau cov GFRC kho kom zoo nkauj thiab cov pwm vaj tsev nyuaj uas qhov kev nthuav dav yog qhov tseem ceeb. Lawv yooj yim tawg thiab muab qhov chaw du yam tsis muaj "fuzzing."
Rau cov ntawv thov siab load,1/2 nti rau 1 nti iav fiber strandsmuab kev txhawb nqa zoo dua qub, pauv qhov yooj yim ntawm kev tawg rau qhov kawg hauv kev tiv thaiv tawg thiab lub peev xwm thauj khoom.
Cov Kev Zoo ntawm Cov Iav Fiber Strands

Kev Nkag Siab Txog Kev Lag Luam: Cov Yam Ntxim Saib Txog Tus Nqi ntawm Cov Iav Fiber Uas Muab Hlais
Yog tias koj tab tom nrhiav qhov zoo tshaj plawstus nqi ntawm cov iav fiber txiav, nws yog ib qho tseem ceeb kom nkag siab txog yam uas tsav lub lag luam. Feem ntau cov nqi raug hais rau ib kilogram lossis ib tuj, thiab lawv hloov pauv raws li:
1.Hom iav:AR-iav kim dua E-iav vim yog cov ntsiab lus Zirconia.
2.Kev ntsuas Chemistry:Cov txheej txheem tshwj xeeb rau cov resins tshwj xeeb (xws li epoxy-compatible sizing) tuaj yeem ua kom muaj nqi siab.
3.Ntim:Cov xaj lag luam wholesale ua lag luam txo tus nqi ib chav piv rau cov hnab me me DIY hobbyist.
4.Kev Thauj Khoom:Vim tias cov iav fiber ntau thiab hnyav, cov nqi xa khoom yog qhov tseem ceeb hauv tus nqi kawg.
Yuav Siv Cov Strands Uas Tau Txiav Lawm Li Cas
Yuav kom tau txais txiaj ntsig ntau tshaj plaws ntawm kojtxoj hlua khicov ntaub ntawv, ua raws li cov lus qhia tshaj lij no:
Rau Kev Sib Tov Pob Zeb:
Txoj Cai "Tail End": Ib txwm ntxiv koj lifiberglass txiav rau concrete thaum kawg ntawm lub voj voog sib tov. Kev sib tov ntau dhau tuaj yeem ua rau cov pob khoom tawg thiab txo lawv cov txiaj ntsig.
Kev Siv Tshuaj: Rau kev tswj qhov tawg, kev siv tshuaj ntawm 0.6kg txog 1.0kg rau ib lub cubic meter yog ib txwm muaj. Rau GFRC, feem pua yuav siab dua (3-5% los ntawm qhov hnyav).
Rau cov khoom sib xyaw ua ke:
Tsis txhob muaj qhov khoob:Thaum sib tov tes iav txiavrau hauv cov resin, siv kev txav uas quav kom tsis txhob ntes cov npuas cua, uas ua rau muaj cov chaw tsis muaj zog hauv qhov chaw kho.
