Fiberglass strand lev hais txog cov ntaub uas tsis yog-woven ua los ntawm iav fiber ntau monofilaments interwoven rau hauv lub network thiab kho nrog ib tug resin binder.Nws yog cov khoom siv inorganic non-metallic nrog kev ua tau zoo heev., Zoo corrosion kuj thiab siab mechanical zog, tab sis qhov tsis zoo yog brittleness thiab tsis zoo hnav tsis kam.3m fiberglass lev feem ntau yog siv los ua cov khoom siv txhawb zog hauv cov ntaub ntawv sib xyaw, cov khoom siv hluav taws xob insulating thiab cov ntaub ntawv thermal rwb thaiv tsev, cov khoom siv hluav taws xob thiab lwm yam kev lag luam hauv lub tebchaws.
Ib, Cov yam ntxwv thiab daim ntawv thov ntawm iav fiber lev
Cov iav fiber ntau muaj cov yam ntxwv ntawm kev kub kub ua haujlwm kub, zoo thermal rwb thaiv tsev kev ua tau zoo, siab lub suab nqus tus nqi, siab tso pa roj purification efficiency, corrosion tsis kam, tiv thaiv npauj-noj, los tiv thaiv mildew, tsawg nqus tus nqi, zoo vibration kuj, nplaim taws. retardant, lub teeb yuag thiab lwm yam.
Thick fiberglass lev yog dav siv los ua fiberglass puag daim ntaub, tiv thaiv corrosion, thermal rwb thaiv tsev, hluav taws-retardant, waterproof khoom, epoxy tooj liab clad laminate thiab hluav taws xob rwb thaiv tsev khoom.Nws yog qhov tsim nyog rau kev ua haujlwm tsis tu ncua ntawm lub tshuab lossis tes nteg ua ntau yam khoom FRP (FRP), daim hlau, kav dej, tso tsheb hlau luam, tso tsheb hlau luam, yachts, khoom siv tu cev thiab lwm yam khoom.
E-iav fiber ntau yog siv rau epoxy tooj liab clad laminates thiab cov khoom hluav taws xob rwb thaiv tsev.Alkali iav fiber nyias nyias yog cov khoom siv zoo rau cov roj teeb cais, lub ru tsev waterproofing, gypsum board tiv thaiv vaj huam sib luag, yas pem teb thiab cov tshuaj yeeb dej caw hauv ob sab phlu rau kev tiv thaiv tawm thiab tiv thaiv corrosion.
、 Cov iav fiber ntau daim ntawv thov yuav tsum tau ua
Tes lay-up: Tes nteg-up yog txoj kev tseem ceeb ntawm FRP ntau lawm hauv kuv lub teb chaws.iav fiber ntau tws strand lev, nruam lev thiabFiberglass Koob Mat txhua tus tuaj yeem siv rau tes nteg.Kev siv cov stitch-bonded xav tau tuaj yeem txo cov txheej txheem thiab txhim kho kev ua haujlwm ntawm tes lay-up.Txawm li cas los xij, vim tias qhov kev xav ntawm stitchbonded muaj ntau cov tshuaj fiber ntau stitchbonding threads, cov npuas tsis yooj yim rau kev tsav tsheb, thiab cov khoom siv fiberglass muaj ntau rab koob-puab npuas, thiab qhov chaw zoo li ntxhib thiab tsis du.Ntxiv rau,Koob Matpwm npog yog luv dua li ntawm kev txiav kev xav thiab kev xav tsis tu ncua.Thaum ua cov khoom nrog cov duab complex, nws yog ib qho yooj yim los tsim voids ntawm khoov.Cov txheej txheem lay-up yuav tsum tau cov lev kom muaj cov yam ntxwv ntawm cov resin infiltration ceev, yooj yim tshem tawm cov npuas npuas thiab pwm zoo.
Pultrusion: Cov txheej txheem pultrusion yog ib qho tseem ceeb ntawm kev sivFiberglass combo lev thiab stitchbonded mats.Feem ntau, nws yog siv ua ke nrog untwisted roving.Sivsib mat thiab stitched xav li cov khoom pultruded tuaj yeem txhim kho lub hoop thiab transverse lub zog ntawm cov khoom thiab tiv thaiv cov khoom los ntawm kev tawg.Cov txheej txheem pultrusion yuav tsum tau cov lev kom muaj cov khoom siv fiber ntau, lub zog tensile siab, ceev resin infiltration tus nqi, zoo saj zawg zog thiab pwm filling, thiab cov lev yuav tsum muaj ib tug ntev ntev.
RTM: Resin hloov moulding (RTM) yog txheej txheem kaw-pwm molding.Nws yog tsim los ntawm ob ib nrab pwm, ib tug poj niam pwm thiab ib tug txiv neej pwm, lub twj tso kua mis pressurizing thiab ib rab phom txhaj, tsis muaj xovxwm.Cov txheej txheem RTM feem ntau yog siv cov lev txuas ntxiv thiab cov ntaub pua plag es tsis yoge-iav tws strand lev.Cov ntawv xav tau yuav tsum muaj cov yam ntxwv uas cov ntawv xav tau yuav tsum tau yooj yim saturated nrog resin, zoo huab cua permeability, zoo resin scour kuj thiab zoo overmoldability.
Winding txheej txheem: Feem ntau, tws strand lev thiab nruam lev yog siv rau winding thiab tsim cov resin-nplua nuj txheej tsuas yog siv rau cov khoom, nrog rau cov hauv ob sab phlu txheej thiab txheej txheej txheej.Cov kev cai rau cov iav fiber lev nyob rau hauv cov txheej txheem winding yog qhov zoo ib yam li cov hauv tes lay-up txoj kev.
Centrifugal casting molding: tws strand lev feem ntau yog siv los ua raw khoom.Lub chopped strand lev yog pre-ntev nyob rau hauv lub pwm, thiab tom qab ntawd cov resin ntxiv rau hauv lub rotating qhib pwm kab noj hniav, thiab cov cua npuas yog tawm los ntawm centrifugation kom cov khoom ntom.Cov ntaub ntawv xav tau yuav tsum muaj cov yam ntxwv ntawm kev nkag tau yooj yim thiab zoo huab cua permeability.
Kev faib tawm ntawm iav fiber ntau lev
iav fiber ntau mats feem ntau muab faib ua peb pawg: nto mats, nruam mats thiab tws strand mats
1.Fiberglass Surface Mat: Feem ntau, txhawm rau txhim kho cov nyhuv saum npoo thiab txo qhov cuam tshuam ntawm daim ntaub qauv ntawm qhov chaw, nws yog txau los ntawm fiber ntau strands;
2. Nruam kev xav: Txoj kev tsim yog txau nrog cov fiber ntau txuas ntxiv;feem ntau yog siv los ua cov khoom siv sib txawv, cov khoom siv sib tw yuav siv me ntsis hauv cov txheej txheem ntawm tes kom nce lub zog interlayer, thiab nws siv tsawg dua.
3.Cplam strand cov ntaub ntawv mat: Txoj kev molding yog sprayed nrog luv fiber strands;
Qhov sib txawv ntawm qhov chaw muaj kev xav, kev xav tsis tu ncua thiab tws strand xav
Qhov kev xav ntawm qhov chaw feem ntau yog siv los txhim kho cov nyhuv saum npoo thiab txo qhov cuam tshuam ntawm daim ntaub qauv ntawm qhov chaw; qhov sib txawv ntawm cov mats txuas ntxiv thiab tws strand mats, raws li lub npe qhia, yog txoj kev tsim yog siv luv fiber ntau filaments los yog nruam filaments.Nruam kev xav feem ntau yog siv los ua cov khoom siv sib txawv, thiab cov khoom siv sib txawv yog siv me ntsis hauv cov txheej txheem ntawm tes kom nce lub zog interlayer thiab siv tsawg dua.
