Dab tsi yog lub zog tensile ntawm basalt ntxhia fiber ntau?

Lub zog tensile ntawm basalt ntxhia fibersyog ib lub ntsiab lus uas yuav tsum tau soj ntsuam los ntawm ntau qhov kev xav. Ua ntej, nws yog ib qho tseem ceeb kom paub meej tias lub zog tensile yog hais txog qhov siab tshaj plaws tensile kev nyuaj siab uas cov khoom tuaj yeem tiv taus ua ntej tawg. Rau Basalt Fiber ntaus, tus nqi no feem ntau yog nruab nrab ntawm2000 MPa thiab 4800 MPa. Tus nqi tshwj xeeb yog cuam tshuam los ntawm cov khoom xws li cov khoom siv raw, cov txheej txheem tsim khoom, thiab txoj kab uas hla fiber ntau.

Vim li cas ua basalt fiberspuas muaj zog tensile siab? Qhov no yog ze ze rau lawv cov microstructure. Basalt nws tus kheej yog pob zeb volcanic nrog cov khoom tseem ceeb xws li silicon dioxide, aluminium oxide, thiab hlau oxide. Tom qab kub-kub melting, cov khoom no tsim ib tug nruam peb-dimensional network qauv, uas muab cov fiber ntau rigidity. Cov cua txias ceev ceev thaum lub sijhawm Fiber ntau txheej txheem ua rau cov txheej txheem molecular denser, ntxiv txhim kho nws cov khoom siv kho tshuab.

Cov yam ntxwv tshwj xeeb cuam tshuam rau lub zog tensile tuaj yeem pom los ntawm cov hauv qab no:

1. Raw Material Composition: Cov muaj pes tsawg leeg ntawm basalt ore los ntawm txawv keeb kwm txawv. Feem ntau, cov khoom siv raw nrog cov ntsiab lus silicon dioxide ntawm 46% thiab 52% tsim cov fibers nrog lub zog zoo dua. Cov ntsiab lus hlau oxide ntau dhau tuaj yeem ua rau txo qis zog.

2. Txheej txheem ntau lawm: Lub melting kub yog qhov zoo tshaj plaws tswj ntawm 1400-1500 ° C. Yog tias qhov kub thiab txias qis dhau, cov yaj viscosity yuav siab, ua rau kev teeb duab nyuaj; yog tias nws siab dhau lawm, nws yuav ua rau cov khoom volatilization. Cov duab nrawm kuj yog qhov tseem ceeb parameter; yog tias nws ceev heev, lub fiber txoj kab uas hla yuav tsis sib npaug.

3. Fiber ntau: Basalt fibers nrog ib tug pa txoj kab uas hla ntawm 9-13 microns muaj ib tug nrov tensile zog kev ua tau zoo. Txawm hais tias theoretically thinner fibers muaj zog dua, lawv muaj feem cuam tshuam rau kev tsim khoom tiag tiag.

4. Kev kho deg: Qee cov khoom raug kho nrog txheej txheej, uas ob leeg tiv thaiv cov fiber ntau thiab tej zaum yuav muaj qee yam cuam tshuam rau nws lub zog.

Hauv kev siv tswv yim, yuav ua li cas xaiv txoj cai basalt fiber ntau? Qhov no yuav tsum tau txiav txim siab raws li kev siv tshwj xeeb. Rau cov ntawv thov uas xav tau lub zog siab, xws li cov khoom siv txhim khu kev qha, nws raug nquahu kom xaiv cov khoom uas muaj lub zog nominal siab tshaj 4000 MPa. Rau lub hom phiaj dav dav, xws li cov ntaub ntawv rwb thaiv tsev, qhov yuav tsum tau muaj zog tuaj yeem txo qis kom tsim nyog. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov ntaub ntawv kuaj sim yuav txawv ntawm qhov ua tau zoo hauv qhov chaw siv tiag tiag. Cov yam ntxwv xws li kub, av noo, thiab kev thauj mus ntev tuaj yeem cuam tshuam rau kev ua haujlwm fiber ntau.

Hais txog kev sib piv ntawm basalt fiber ntau lub zog nrog lwm cov fibers, ob peb cov ntsiab lus siv tau siv rau kev siv: lub zog tensile ntawm zoo tib yam E-iav fiber ntau yog li 3000 MPa, S-iav fiber ntau tuaj yeem ncav cuag 4500 MPa, thiab carbon fiber nyob nruab nrab ntawm 3000-7000 MPa. Los ntawm qhov kev xav no, lub zog ntawm basalt fiber yog nyob rau nruab nrab-rau-siab. Txawm li cas los xij, nws qhov zoo yog nyob rau hauv cov khoom siv qis qis thiab zoo dua qhov kub thiab txias thiab kev ruaj ntseg tshuaj.

Nyob rau hauv cov nqe lus ntawm kev tswj kom zoo, ib leeg-fiber tensile xeem txoj kev yog tam sim no siv los txiav txim lub zog. Thaum lub sij hawm sim, tshwj xeeb yuav tsum tau them rau tus qauv npaj txheej txheem kom tsis txhob muaj kev qhia txog qhov tsis xws luag vim tib neeg yam. Cov qauv kev lag luam feem ntau xav tau kev sim tsawg kawg 50 fibers thiab noj qhov nruab nrab tus nqi raws li qhov kawg tshwm sim. Txij li thaum muaj qee qhov kev tsis sib haum xeeb hauv fiber ntau, qhov kev ntsuas no tuaj yeem ua kom ntseeg tau ntawm cov ntaub ntawv.

Hais txog kev txhim kho yav tom ntej, cov kws tshawb fawb tau sim ua kom muaj zog ntxiv ntawm basalt fibers los ntawm txoj kev xws li nanomodification thiab composite spinning. Piv txwv li, ntxiv me me ntawm cov khoom tshwj xeeb rau cov khoom siv raw tuaj yeem ua kom zoo dua cov khoom yaj; siv electromagnetic teb-pab kos duab thev naus laus zis tuaj yeem txhim kho qhov sib xws ntawm cov qauv fiber ntau. Txawm hais tias cov txheej txheem tshiab no tseem nyob rau theem kev sim, lawv qhia tau zoo rau daim ntawv thov.

Kev tuav lub zog tensile kuj yog ib qho kev txhawj xeeb rau cov neeg siv. Kev sim cov ntaub ntawv qhia tau hais tias nyob rau hauv ib qho chaw qhuav ntawm chav tsev kub, lub zog tuav tus nqi ntawm zoo basalt fibers tseem tuaj yeem ncav cuag ntau dua 90% tom qab kaum xyoo. Txawm li cas los xij, nyob rau hauv qhov kub thiab txias los yog corrosive ib puag ncig, tus nqi no yuav txo qis. Yog li ntawd, hauv kev siv engineering tiag tiag, kev tiv thaiv tsim nyog yuav tsum raug xaiv raws li ib puag ncig.

Thaum kawg, nws yuav tsum tau nco ntsoov tias txawm hais tias basalt fiber ntau muaj lub zog tensile siab, qhov kev sib txuas ntawm kev sib txuas kuj yuav tsum tau xav txog hauv cov khoom tshwj xeeb. Piv txwv li, hauv daim ntawv thov kev txhawb nqa pob zeb, lub zog sib txuas ntawm cov fiber ntau thiab cov matrix feem ntau tseem ceeb dua li lub zog ntawm fiber ntau nws tus kheej. Qhov no yuav tsum tau ua kom zoo dua los ntawm kev kho saum npoo los yog ntxiv cov coupling agents.
