Dab tsi yog cov yam ntxwv tseem ceeb thiab kev txhim kho cov ncauj ke ntawm cov fiberglass composites?
Iav yasCov ntaub ntawv puas xa mus rau cov ntaub ntawv tshiab uas tau ua tiav thiab tsim los ntawm kev siviav yasRaws li ntxiv lub cuab lub zog thiab lwm yam khoom siv sib xyaw ua matrix. Vim yog cov yam ntxwv ntawmiav yasCov ntaub ntawv sib xyaw lawv tus kheej, lawv tau siv dav hauv ntau thaj teb. Kab lus no ntsuas qee yam yam ntxwv ntawmiav yasCov ntaub ntawv sib xyaw thiab muab qee cov qauv thiab cov lus qhia rau lawv txoj kev txhim kho, uas tuaj yeem siv rau kev nkag siab zoo thiab tshawb pom cov ntaub ntawv fiberglass sib xyaw.
Cov yam ntxwv tseem ceeb ntawm cov ntaub ntawv fiberglass sib xyaw:
1. Cov khoom siv zoo tshaj plaws. Lub zog tensile ntawmiav yasCov ntaub ntawv sib xyaw yog qis dua li ntawm cov hlau, siab dua li ntawm cov hlau uas muaj ntau dua li 3 zaug ntawm cov hlau thiab 10 zaug ntawm cov hlau cooj.
2. Zoo corrosion tsis kam. Los ntawm kev xaiv raw tsim nyog thiab tshawb fawb tuab tsim,iav yasCov ntaub ntawv sib xyaw tuaj yeem siv rau lub sijhawm ntev hauv cov huab cua organic ib puag ncig xws li cov kua qaub, alkali, thiab ntsev.
3. Zoo thermal rwb thaiv tsev kev ua haujlwm. Cov khoom siv fiberglass muaj cov yam ntxwv muaj cov yam ntxwv ntawm cov thermal tsawg thiab yog cov khoom siv hluav taws xob zoo tshaj plaws. Yog li ntawd, nyob rau hauv cov xwm txheej ntawm qhov sib txawv me me, tsis tas yuav muaj kev tiv thaiv tshwj xeeb kom ua tiav cov txiaj ntsig thermal rwb thaiv tsev zoo.
4. Me me thermal nthuav kev coefficiention. Vim yog cov thermal me me nthuav tawm coefficient ntawmiav yasCov ntaub ntawv sib xyaw, lawv tuaj yeem siv tau ua haujlwm ntau nyob rau hauv ntau yam hnyav xws li sab npoo av, av av, hiav txwv txias, thiab suab puam.
5. Kev tiv thaiv hluav taws xob zoo heev. Nws tuaj yeem siv los ua kom cov insulators. Nws tseem tuaj yeem tswj cov khoom zoo dielectric zoo ntawm cov nquag nquag. Nws muaj cov hloov microwave zoo thiab yog haum rau siv hauv lub hwj huam kis thiab minefields.
Txoj kev txhim kho txuas ntawm cov khoom siv fiberglass muaj raws li hauv qab no:
1. Tam sim no, siab - Kev ua yeeb yam fiberglass muaj cov peev xwm loj hlob, tshwj xeeb tshaj yog siab} silicaiav yasmuaj kev zoo. Muaj ob txoj kev loj hlob txuas rau qhov siab- performance performance performanceiav yas: Ib qho yog tsom rau kev ua tau zoo dua, thiab lwm qhov yog los tsom rau kev tshawb nrhiav thev naus laus zis ntawm high - kev ua yeeb yamiav yas, thiab siv zog los txhim kho cov txheej txheem kev ua tau zoo ntawm high - Kev ua yeeb yam fiberglass, thaum txo tus nqi thiab txo cov kuab paug thiab txo cov kuab paug thiab txo cov pa paug.
2. Muaj qee qhov shortcomings nyob rau hauv cov khoom npaj: kev npaj ntawm qee qhov siab fiberglass tseem muaj teeb meem xws li iav crystallization, siab nyoos fiber ntau, thiab tus nqi siab. Nyob rau tib lub sijhawm, nws tsis tuaj yeem ua tau raws li qhov xav tau ntawm lub zog hauv qee qhov kev siv tshwj xeeb. Thaum thermosetting cob yog siv los ua cov matrix, cov khoom npaj txhij muaj cov teeb meem muaj qhov teeb meem ntawm kev nyuaj siab ua thiab rov ua dua tshiab. Nws tsuas yog ua tiav los ntawm kev txiav, thiab kev rov ua dua tshiab tsuas yog nqa tawm los ntawm cov tshuaj lom tshwj xeeb thiab cov oxidants muaj zog. Cov nyhuv tsis zoo tagnrho. Txawm hais tias cov khoom siv hluav taws xob ua rau muaj kev tsim tawm, cov teeb meem raug nqi tseem yuav tau tswj hwm.
3. Nyob rau hauv cov txheej txheem synthesis ntawmiav yas, cov fiberglass sib xyaw tshiab yog npaj nrog kev pab ntawm ntau cov synthesis thev naus laus zis thev naus laus zis. Nyob rau hauv xyoo tsis ntev los no, nyob rau hauv thiaj li yuav tau raws li cov kev xav tau nyob rau ntau yam kev tshwj xeeb, ntau yam thev naus laus zis tau tsim los ua kev hloov kho tshwj xeeb rau saum npoo ntawmiav yasCov. Kev hloov kho deg yog qhov hloov tshiab hauv kev txhim kho cov fiberglass muaj cov khoom siv thev naus laus zis yav tom ntej.
4. Yav Tom Ntej, tshwj xeeb tshaj yog cov kev thov hauv cov thawj coj ntawm kev loj hlob, thiab qhov zoo ntawm cov thawj coj ntawm kev lag luam yuav pom tseeb. Piv txwv, Tuam Tshoj cov tuam txhab fiberglass sawv cev los ntawm Jushi pab pawg yuav ua si ib tug coj ua thiab coj txoj kev ua haujlwm hauv ntiaj tebiav yaskev lag luam yav tom ntej.Iav yasCov ntaub ntawv sib xyaw tau dhau los ua ib qho ntawm cov ntaub ntawv raw tseem ceeb rau kev lag luam automotive.Iav yasThermopoplastic cov ntaub ntawv muaj ib daim ntawv thov loj hlob vim lawv txoj kev lag luam zoo thiab ua tau zoo. Tam sim no, cov dav siviav yasThermoplastic cov ntaub ntawv siv hluav taws xob muaj xws li lub cuab yeej muaj vaj huam sib luag, npog lub cav thiab cov qauv hauv feem ntau ntawm cov tsheb.
5. Me thiab nruab nrab {- qhov chaw ua haujlwm me dua li ob peb lub iav fiber ntau pob nyiaj tau los ntawm 35% ntawm kuv lub teb chawsiav yasKev lag luam tawm. Feem ntau ntawm lawv muaj ib ntau yam, siv tshuab tsis muaj zog, thiab ntau dua 90% ntawm tag nrho cov neeg ua haujlwm. Lawv muaj tsawg cov peev txheej thiab kev tswj hwm tsis zoo ntawm kev lag luam kev pheej hmoo. Lawv yog cov tseem ceeb thiab kev nyuaj ntawm kev lag luam kev hloov tswv yim. We should actively support and guide small and medium-sized enterprises to take the path of coordinated development, and achieve the goal of development by forming small and medium-sized enterprise groups and strengthening cooperation and competition with the outside world. Nrog kev sib nrig sib pom ntawm kev lag luam, kev sib tw ntawm cov lag luam tsis yog ib qho kev sib ntaus, tab sis yog manifested raws li kev koom tes nrog kev koom tes thiab kev sib koom tes.
